The best aluminium profiles, compared.
Top pick: PULUME black LED channel, 6 m Best value: Fabal equal angle, 15 × 15 × 1.5 mm, 1 m – Highest value part in the set: about £10.16 for 1 m of stated 6063-T6 angle, with 4.6 from 29 reviews. Updated 22.10.2026.
An aluminium profile on amazon.co.uk is a long extruded section. Shoppers use that name for three different buys: slotted 2020 rail for a frame, a channel that hides an LED strip, and mill-finish angle or for a bracket or an edge. A plain 20 × 20 × 2 mm channel does not take 2020, and a 2020 bar does not include a milky diffuser. Judge the family and the millimetre size first, then the finish, then whether the box contains the nuts, the diffuser, or only the bar. How the families differ is in the [aluminium profile buying guide](/hub/diy-supplies/aluminium-profile/sub/aluminium-profile-buying-guide). Match an LED strip to the inner width, not the outside of the profile. Widths stated here are 12 mm, about 12 mm, 13 mm, 1–15 mm, or up to 18 mm. No kept listing includes the LED strip. iMetrx kits do not list in-line couplers. Black anodised 2020 scratches once the film is off. Mill finish is for later paint or anodising, not a show surface. One review measured 19.8 mm outside instead of 20 mm.

Question 1 of 2
Which job is this profile for?
PULUME lists a matte black U-channel at £21.24, with 6 m of track stated, 12 black clips, 12 end caps, 12 screws and 12 dowels, plus milky covers in the components field, at 500 g. The amazon.co.uk line is 5.0 from 6 reviews, and none of those six states a fault. Buyers used a 3000 K COB strip, cut the aluminium with a fine hacksaw, and said the clips held under a cabinet that had no valance. The listing does not give an inner width in millimetres, so you cannot check a 12 mm tape against a number on the page. One review calls the diffuser black while the listing says milky white. The usage field says indoor and outdoor, and the listing does not show a verified seal. Piece length is implied by a 100 cm item-length field and a unit count of 6, not spelled out as six 1 m bars.
Pros
Cons
Best for: You want a black surface channel for a cabinet and you can measure the opening on arrival before you buy the strip.
Less suitable: You need a stated inner width before you order, or a review sample larger than six.
Specifications
Common questions
Is it compatible with any LED strip?
The listing does not give an inner width in millimetres. The strip is not included, so measure the opening before you order tape.
What length is supplied?
The bullets say 6 m of black track. The item-length field is 100 cm and the unit count is 6. A cross-section size is not given.
Does the cover clip on?
Reviews say the cover clips on after the channel is fitted, and that a fine hacksaw cuts the aluminium.
inShareplus lists a silver single-sided plaster-in channel at £32.99 for strips from 1 mm to 15 mm wide, with six milky covers and a packed weight of 650 g. The same bullet says six 1 m pieces and also a 10 m total, so you cannot treat both figures as the length in the box. The amazon.co.uk line is 4.7 from 8 reviews. A frosted cover made one strip look like a line rather than dots, and a buyer said the LEDs stay reachable after the skim. Fitting into an existing wall is described as fiddly compared with a room that is still being boarded. Screws, plugs and end caps are not in the packing line. The listing marks the profile not water resistant and indoor.
Pros
Cons
Best for: You are plastering a room and you will confirm the metre count on the live page before you order strips to match.
Less suitable: You need one clear total length, fixings in the box, or a wet-room seal.
Specifications
Common questions
What is actually in the box?
The packing line lists six 1 m channels and six milky covers. Screws, plugs and end caps are not listed. The same line also says the total length is 10 m.
What strip width fits?
The listing says flexible or rigid strips from 1 mm to 15 mm. The strip is not included.
Can it go in a wet room?
The listing marks it not water resistant and indoor. It does not claim a sealed bathroom install.
Fabal’s equal angle is one metre of 15 × 15 × 1.5 mm 6063-T6 at £10.16, a true 90 degree corner in mill finish, with a stated cut tolerance of ±2 mm and no fixings. The amazon.co.uk line is 4.6 from 29 reviews. Buyers used a length as trim on a 1980s record deck and as a hose-tool bracket, and the seller rang at least two people to confirm the size before dispatch. The wall is 1.5 mm, so it is light rather than a structural post. Reviews jump between sizes, including a complaint about £8.28 for 300 mm of 20 × 20 × 2 mm, so this 15 × 15 × 1.5 mm listing is not what every reviewer received. The listing says you can cut, drill, weld or paint it, and the stored reviews do not describe a painted coat. Corrosion resistance is a listing sentence, with no coating thickness.
Pros
Cons
Best for: You need a cheap 1 m mill-finish corner for trim or a light bracket and you will confirm 15 × 15 × 1.5 mm at checkout.
Less suitable: You need a slotted frame rail, an LED cover, or a thick structural angle.
Specifications
Common questions
Can it be painted?
The listing says the mill-finish bar can be cut, drilled, welded or painted, and that it is not sold as a finished decorative surface.
Is it resistant to corrosion?
The listing describes 6063-T6 as corrosion-resistant. It does not give a test result or a coating thickness.
What size is this listing?
15 × 15 × 1.5 mm at 1000 mm. Reviews on the page also discuss other sizes, including a 20 × 20 × 2 mm length.
The iMetrx kit is eight black 200 mm 2020 V-slot bars at £25.99, with angle brackets, connector brackets, M5 bolts, T-nuts and two hex keys, packed at 830 g. Across the shared amazon.co.uk line the score is 4.6 from 24 reviews, and those texts also describe 300 mm and 700 mm kits, so they are not proof that this 200 mm length was reviewed on its own. Reviewers use the bars for printer, CNC and flat frames, and they say 2020 nuts from other makers fit the same slot once the film and swarf are off. The slot width in millimetres is not on the listing. Sharp chips stick to the packing film, cut ends stay sharp, and the anodising scratches if the frame is moved often. In-line couplers are not in the contents list.
Pros
Cons
Best for: You are bolting a short printer or shelf frame from 200 mm lengths and you will clear the film before the bars touch.
Less suitable: You need a stated slot width, separate reviews for this length, or a straight coupler in the box.
Specifications
Common questions
Does this kit include the brackets?
Yes. The listing includes eight angle brackets, eight connector brackets, M5 bolts, slider nuts, T-nuts and two hex keys, plus eight 200 mm bars.
Is an LED strip included?
No. This is a structural 2020 extrusion kit, not a lighting channel.
Can you assemble it without tools?
No. Reviews describe bolts and grub screws turned with the supplied hex keys.
This iMetrx kit lists eight black 300 mm 2020 V-slot bars at £29.99, part iMetrx-UK-1425, with the same bracket, M5 bolt, T-nut and hex-key set as the 200 mm kit and a packed weight of 1.2 kg. The amazon.co.uk line is 4.6 from 24 reviews, the same block as the shorter listing, and one of those reviews does say the set had eight 300 mm lengths. Reviewers describe a neat black anodising and hardware that squares a light frame or makes a T joint. Slot width is still not printed in millimetres, and a review of a 700 mm kit in the same block says in-line couplers are bought separately. Swarf under the film and sharp ends show up in those shared comments, and the anodising marks if the build is shifted around.
Pros
Cons
Best for: You want 300 mm 2020 lengths with brackets in the box and you will treat the 24-review line as shared.
Less suitable: You need a unique review count for 300 mm bars, a stated slot width, or end-to-end couplers included.
Specifications
Common questions
How is this different from the 200 mm iMetrx kit?
The listing length is 300 mm rather than 200 mm, the part number is iMetrx-UK-1425, and the packed weight is 1.2 kg. The bracket and bolt list matches the shorter kit.
Do the reviews all describe 300 mm bars?
No. The review block is shared with the 200 mm listing and also includes a comment about a 700 mm kit. The title and size field on this listing say 300 mm.
Are straight couplers included?
They are not in the contents list. A review of a longer kit in the same review block says in-line connectors are bought separately.
Fabal’s mill-finish channel is one metre of 20 × 20 × 2 mm 6063-T6 at £13.20, with a stated cut tolerance of ±2 mm and no fixings, diffuser or brackets. The amazon.co.uk line is 4.6 from 7 reviews, and one UK review stored with the listing praises a neat fit as a blind support and does not describe a fault or a cut. The listing says the bar can be cut, drilled, welded and machined, and that the mill finish is for paint, powder coat or anodising later, not a show surface as supplied. It is a plain U or C section. It does not take 2020 T-nuts, and the 6063-T6 name on this listing is not a strength test of this particular metre.
Pros
Cons
Best for: You need a plain 1 m fabrication channel in a stated 20 × 20 × 2 mm size and you will finish the surface yourself.
Less suitable: You need T-nuts, a lighting diffuser, or more than one review that describes the metal.
Specifications
Common questions
Can it be painted?
Yes. The listing says the mill finish is ready for painting, powder coating or anodising, and that it is not a decorative finish as supplied.
Is it easy to cut?
The listing says it can be cut, drilled, welded and machined. The only stored review does not describe a cut.
Is this a 2020 T-slot rail?
No. It is a plain 20 × 20 × 2 mm U or C channel with no T-nuts or V-slot in the contents.
The LightingWill pack is six silver 1 m U-channels at £21.55, with a stated inner width of 12 mm, six milky covers, 12 end caps and 12 clips, and no LED strip. Across 2,047 amazon.co.uk reviews the line is 4.5, the only large sample in this set, and buyers use the channels under cabinets, on shelves, in wardrobes and around mirrors. A Philips Hue strip fitted after the rubber sleeve came off, and COB tape is mentioned too. The cover is tight: reviewers say it cracks if you hammer it, clips can need bending, and every end cap has a cable hole that sits loose. Screws were too long for boards about 20 mm thick in one review, and sparse LEDs still show as dots. A dark cover in the same review pool dims the light, so this silver milky set is the one to match to the title, not every style mixed into those 2,047 reviews.
Pros
Cons
Best for: You are housing a strip up to 12 mm wide on cabinets or shelves and you will press the cover in from one end.
Less suitable: You need the strip in the box, a plaster-in flange, or a cover you can hammer home.
Specifications
Common questions
What LED strip width fits?
The listing states an inner width of 12 mm for strips from 1 mm to 12 mm. The strip itself is not included.
Does it come with a diffuser?
Yes. Six milky white covers are listed, plus 12 end caps and 12 clips.
Is it straightforward to fit the cover?
Reviews often say the cover is tight. The repeated method is to start at one end and press along, rather than hammering it.
CNCMANS lists four black 600 mm 2020 V-slot rails at £21.33, with a title slot of 6.2 mm, four L-brackets, 50 T-nuts and a wrench, at 450 g. The amazon.co.uk line is 4.5 from 48 reviews, and one review on the page confirms four 600 mm rails, while several others describe a 1000 mm option that arrived short. Reviewers use filmed lengths for frames and a laser enclosure, and one used a length to stiffen a load-cell plate. A buyer measured 19.8 mm outside rather than 20 mm and could not match existing 20 mm hardware. Swarf under the film scratches the anodising, and a longer-size review reports untapped bracket holes and a missing grub screw. The listing claims compatibility with 20-series fasteners, which that 19.8 mm measurement puts in doubt for a mixed frame.
Pros
Cons
Best for: You want about 600 mm of black 2020 with a stated 6.2 mm slot and a bag of T-nuts, and you will check the outside width against hardware you already own.
Less suitable: You need a guaranteed 20.0 mm match to existing rail, or reviews that all describe this 600 mm length.
Specifications
Common questions
What length is this listing?
The title says four pieces at 600 mm. One review on the page confirms four 600 mm rails. Other reviews describe a 1000 mm option.
Will it match every 20 mm rail?
The listing says it is compatible with 20-series fasteners. One review measured 19.8 mm outside and could not use their existing 20 mm hardware.
Are brackets included?
Yes. The contents line lists four L-brackets, 50 T-nuts and a wrench.
LightingWill’s plaster-in pack is six 1 m double-flange channels at £30.99, internal width 13 mm, with milky covers, 12 end caps, 12 screws and 12 wall plugs, at 860 g. The amazon.co.uk line is 4.5 from 9 reviews. Buyers describe perforated sides for a flush plasterboard line in lofts, kitchen wall units and lowered ceilings, and they treat the aluminium as a heat path. A fine blade is needed: a rough cut bends the lip. The included screws and plugs felt cheap to one buyer, who used their own fixings in plasterboard. The channel was wider than a thin COB tape needed, bright strips can still show dots, and runs longer than 1 m need joins. The flush finish depends on the plastering, not on the extrusion alone.
Pros
Cons
Best for: You are boarding a ceiling or wall and can plaster a 13 mm double-flange channel in as the boards go up.
Less suitable: You want a clip-on cabinet channel, a thin COB-only slot, or a large review sample.
Specifications
Common questions
What strip width fits?
The listing says an internal width of 13 mm for strips from 1 mm to 13 mm. The LED strip is not included.
Is this a surface clip-on channel?
No. It is a double-flange plaster-in profile for drywall and ceilings. Reviews describe fixing it before plastering.
Can it be painted?
The listing does not say whether the metal is paintable.
LightingWill’s five-pack is five silver 1 m U-channels at £19.95, inner width about 12 mm, with five milky PC covers, 10 end caps and 10 clips, at 570 g. The amazon.co.uk line is 4.4 from 134 reviews. Buyers cut the bars for under-cabinet runs, and one review praises a push-fit cover so you do not need spare length to slide a strip back out. Another buyer still saw individual diodes when they sat about 2 cm apart and close to the plastic. Bars arrived with a slight curve that had to be bent straight, one end cap did not fit the track, and there is no joiner between lengths. The cover is tight to slide and not simple to press. The pack is five metres only, which annoyed a buyer who wanted a single metre.
Pros
Cons
Best for: You need five metres of silver U-channel for a strip near 12 mm and you can straighten a slight curve.
Less suitable: You want one metre only, a stated joiner, or a guarantee that every diode disappears.
Specifications
Common questions
How many metres are in the box?
Five channels at 1 m each, with five covers, 10 end caps and 10 clips.
Will the cover hide every LED dot?
One review still saw individual diodes when they were about 2 cm apart and close to the plastic. Another review reported no spotting.
Is a joiner included?
No. A review notes there is no method in the kit for jointing lengths.
YGS-Tech lists six silver 1 m plaster-in profiles at £34.99, wall 1.0 mm, for strips up to 18 mm wide, with six milky PC covers and a packed weight of 500 g. The flange is single-sided and perforated for plasterboard. The listing has no customer-review score and no review text, so there is no UK comment on how the lip cuts or how the skim looks. Screws, plugs and end caps are not listed. The listing says the profile can be cut and that you should check the strip width first. There is no water rating. At £34.99 it is the dearest plaster-in six-pack in this set, and you are buying on the title measurements alone.
Pros
Cons
Best for: You need a wide plaster-in opening, up to 18 mm, and you will judge the metal when it arrives because nobody has reviewed it here.
Less suitable: You want amazon.co.uk reviews, included fixings, or a cheaper surface channel for an existing cabinet.
Specifications
Common questions
What LED strip width fits?
The listing says compatible strips up to 18 mm wide. The strip is not included, and the buyer is told to check the width first.
Can it be cut?
Yes. The listing says the profile can be cut to the installation length.
How is it rated on amazon.co.uk?
The listing has no customer-review score and no review text.
Shelf prices, stars and review counts are the amazon.co.uk figures stored for these eleven listings, captured 19 October 2026. There is no lab test and no load rating. The stored score is 0–100 from four parts: stars (35), review sample (25), fit for the stated family (20) and value in this set (15). Those parts are published below as 37, 26, 21 and 16 so the weights sum to 100. The highest score is the top pick, once. Best value is the highest value-part score that is not that top pick, once. A line from fewer than 10 reviews is capped on the star part. No rating line scores 0 on stars and on sample.
Stars
37%Amazon stars scaled as (rating / 5) × 35 in the stored score, rounded to the nearest integer. Fewer than 10 reviews is capped at 32 on that part, so a 5.0 from six reviews cannot lead on stars alone. No rating line scores 0.
Review sample
26%1,000 or more reviews scores the top of this part. 100–999, 30–99, 10–29 and 1–9 step down. No review line scores 0. A large sample is why the LightingWill six-pack leads.
Fit for the stated family
21%Points follow a stated opening or section, an honest length, and the fixings that family needs. A missing slot width, a shared review block, mixed lengths, a 6 m versus 10 m contradiction, or an LED channel with no inner width costs points.
Value in this set
16%The lowest useful mill-finish metre with a real review count scores highest on this part. A lighting kit can look cheap per metre and still lose this part to the £10.16 angle. Best value is that angle, not the top pick.
Buy the family before the metre price. An aluminium profile on amazon.co.uk may be 2020 V-slot, an LED U-channel, a plaster-in flange, or mill-finish angle and channel. Fixings do not cross those families. Match an LED strip to the inner width. Read the contents line, because the strip is not in these boxes. Only the two Fabal listings print 6063-T6, and that name is not a strength test of the metre in your hand.
An aluminium profile on amazon.co.uk is a long extruded section. Shoppers use that name for three different buys. Slotted 2020 rail is for frames. A channel hides an LED strip. Mill-finish angle or U-channel is for brackets and edging. Quality starts with the family and the millimetre size, then the finish, then whether the box contains the nuts, the diffuser, or only the bar. Fixings do not cross those families.
A plain 20 × 20 × 2 mm channel does not take 2020 T-nuts. The Fabal channel is that plain section. The black kits from iMetrx and CNCMANS are the V-slot rail. One CNCMANS review measured 19.8 mm outside.
Match the strip to the inner width. Figures in this set are 12 mm, about 12 mm, 13 mm, 1–15 mm, or up to 18 mm. PULUME does not state one. A milky cover does not mean every diode disappears.
No kept listing includes the LED strip. iMetrx kits do not list in-line couplers. The LightingWill five-pack has no joiner. Shared star scores across lengths are not separate proof of each size.
The first split is the family, because fixings do not cross it. This set has 2020 V-slot, LED U-channel, plaster-in flange, mill-finish angle and mill-finish channel. A 20 mm plain channel is not 2020, and a 2020 bar is not an LED cover. Next is the section in millimetres and the piece length. Multi-size listings mix reviews. The two iMetrx kits share 4.6 from 24 reviews, and those texts also mention other lengths. Fabal states a ±2 mm cut tolerance.
Read the contents line before the star average. No kept listing includes the LED strip. Lighting channels may include a milky cover, end caps and clips. The LightingWill plaster-in pack adds screws and wall plugs. inShareplus and YGS-Tech do not list screws, plugs or end caps. iMetrx kits include brackets, M5 bolts, T-nuts and hex keys, and they do not list in-line couplers. CNCMANS lists four L-brackets, 50 T-nuts and a wrench. Both Fabal bars are the section only. Finish is the next check.
Three typical situations, each with a recommendation from this comparison.
You need an inner width, a diffuser and a strip you buy separately. The LightingWill six-pack is the top pick at about £21.55: 12 mm inside, milky covers, caps and clips, 4.5 from 2,047 reviews. Press the cover in from one end. It is not a plaster-in flange.
You need 2020 rail, a nut thread and an honest length. The CNCMANS pack is four black 600 mm bars at about £21.33, title slot 6.2 mm, with 50 T-nuts and four brackets, 4.5 from 48 reviews. One buyer measured 19.8 mm outside. Check that against hardware you already own.
You need a mill-finish section in millimetres, not a light. The Fabal equal angle is best value at about £10.16: 15 × 15 × 1.5 mm, 6063-T6 on the listing, 4.6 from 29 reviews. Confirm that size at checkout. Reviews on the page also discuss other sizes. It is not a slotted rail.
The top pick is the LightingWill LED channel, six 1 m lengths at about £21.55. It scores 89: a stated 12 mm opening, milky covers, caps and clips, and 4.5 from 2,047 reviews, the only large sample here. The strip is not in the box, and the cover can crack if you hammer it. Best value is the Fabal equal angle at about £10.16, one metre of 15 × 15 × 1.5 mm 6063-T6, 4.6 from 29 reviews. It is for trim or a light bracket, not for a lamp. Neither award is a Britain-wide best bar, and neither score is a measured strength test.
Fabal equal angle, 15 × 15 × 1.5 mm, 1 m
Highest value part in the set: about £10.16 for 1 m of stated 6063-T6 angle, with 4.6 from 29 reviews.
