The best heavy duty racks, compared.
Top pick: Forthcan 140 cm wire rack Best value: DIVCHI 5-tier boltless rack – About £21.29 for one bay, with 4.0 from 666 reviews, when you will seat the tabs lightly. Updated October 2026.
A heavy duty rack is a freestanding garage or shed bay, not pallet racking and not a wall bracket. On amazon.co.uk you are choosing a cheap boltless frame, a wire rack that may have wheels, or one solid metal shelf. What matters is a size that fits the doorway, a load line you can read without a second conflicting figure, and reviews that still call the uprights straight after a mallet. That review text is the same block as the black pair, so the two counts are not two samples. Doorway, load, deck and damp are set out in the [heavy duty rack buying guide](/hub/workshop/heavy-duty-rack/sub/heavy-duty-rack-buying-guide). The largest kilogram in the title is not that check.

Personal buying guide
Question 1 of 2
How many bays do you need?
The Forthcan 14045180-5B is a black five-tier wire rack about 140 cm wide at £129.99, with levelling feet and no wheels stated. Each shelf is stated at up to 640 lb, about 290 kg if converted, and 3,200 lb total with the feet, which the kilogram field prints as 1,451.5 kg. The star line is 5.0 from one review, and the capture has no review text, so there is no buyer account of assembly or rust. The minimum door width is 140 cm, which rules it out of most UK internal doors and many garage side doors. A size line also prints 180.3 × 140.9 × 45.7 cm beside the 140 × 45 × 180 cm bullets. Tool-free assembly in under 15 minutes is a claim, not something a review in this capture confirms.
Pros
Cons
Best for: You have already measured a 140 cm route into the garage and you accept buying on a single rating.
Less suitable: You are treating 5.0 from one review as evidence the bay is the strongest rack in the set.
Specifications
Common questions
Will it fit through a standard doorway?
The minimum door width is printed as 140 cm. Measure the door before you order.
What load is stated?
Each shelf up to 640 lb, and 3,200 lb total with the levelling feet. The kilogram field is 1,451.5 kg, which matches 3,200 lb.
How many written reviews are in the capture?
The star line is 5.0 from 1 review. The raw file has no review text.
The Mapleyard wire rack is a black five-tier unit at £67.99 with four wheels and four levelling feet. The bullets state 114 kg per shelf and 567 kg when it is standing still, and they do not print a moving limit. Across 11 reviews at 4.7, buyers say it is easy to clip together and useful in a garage, and they also say it is not as heavy-duty as the advertising and that the wire feels thin. One review says only one wheel locks, against a two-lock claim in the bullets. The title prints 90 × 35 × 183 cm while the bullets print 91 × 40 × 193 cm, so the doorway is not a single number. The material-type field says wood, which contradicts the alloy-steel wire in the bullets. An NSF sentence appears in the bullets without a certificate image in the capture.
Pros
Cons
Best for: You want a wheeled wire rack for crates and bins, and you will check both locks before you roll it.
Less suitable: You need a flat deck for loose fixings, or a review sample in the hundreds.
Specifications
Common questions
Does this Mapleyard rack have wheels?
Yes. The bullets say four wheels, two of them lockable, plus four levelling feet. One review says only one wheel locks.
Which size should you plan for?
The bullets say 91 × 40 × 193 cm. The title says 90 × 35 × 183 cm.
What load is stated when it is standing still?
The bullets say up to 567 kg total when stationary and up to 114 kg per shelf. A moving limit is not printed.
The Forthcan 183672-5B is a black five-tier wire rack at £93.99, about 91 cm wide, with four wheels and four levelling feet. The bullets state 1,100 lb with the feet down and a recommended maximum of 550 lb while it is moving, about 499 kg and 249 kg if you convert the pounds. Across 23 reviews at 4.6, several buyers say it assembles easily and matches the advertisement, while at least one title says not to waste your money and another cites poor delivery. Height is printed as 190.5 cm with the wheels and 182.9 cm on the dimensions line. Two of the four castors are said to lock. The sample is short, so the 4.6 does not describe a settled pattern such as bent uprights.
Pros
Cons
Best for: You want a wire rack you can roll, and you will use the lower figure while it is moving.
Less suitable: You will load it to the standing figure and then wheel it, or you need a board for loose screws.
Specifications
Common questions
What load applies when the rack is moving?
The bullets say 1,100 pounds with the levelling feet, and a recommended maximum of 550 pounds while moving on the wheels.
Are the wheels lockable?
The bullets say two of the four castors lock, and that four levelling feet are included.
How tall is it?
One bullet says 190.5 cm high with the wheels. The item-dimensions line says 182.9 cm high.
The Forthcan 11545180-5B is a black five-tier wire rack, 115 × 45 × 180 cm, at £110.99, with 25 mm pipes stated and no wheels in the listing. The only load figure printed is 907 kg, used as both the maximum and the minimum, with no per-shelf split. Across 14 reviews at 4.5, the written heads praise strength and a size that fitted a tight space, and they criticise the instructions and, in one case, delivery. The bullets claim a tool-free clip build in about 15 minutes for one person, and they say the top bar can be split to make new shelves. The minimum door width is 115 cm, so a standard internal door will not pass it. Little in this short set describes a repeated frame failure, and 907 kg remains an untested listing figure.
Pros
Cons
Best for: You have measured a 115 cm opening and you want a wide standing wire rack rather than wheels.
Less suitable: You need a per-shelf kilogram, a normal internal door, or a sample larger than 14 reviews.
Specifications
Common questions
What load is printed?
907 kg appears as both the maximum and the minimum weight. A per-shelf kilogram is not printed.
How wide is the bay?
The bullets say 115 × 45 × 180 cm, and the minimum door width is 115 cm.
Does it need tools?
The bullets say no tools: snap the clips onto the posts and slide the shelves down. They allow about 15 minutes for one person.
The SUPEER is a black five-tier metal shelf, 183 × 90 × 40 cm, at £89.99, with rubber foot pads and no wheels stated. The bullets say up to 200 kg per shelf and 1,000 kg for the five shelves, while a separate field says a minimum weight of 600 kg. Across 149 reviews at 4.4, buyers call it solid once built and usable as garage shelving, and they also call the plastic connectors and feet brittle and some frame sections thin. At least one review says assembly needs a mallet, which the listing does not spell out as a method. The item weight is about 20.6 kg, and the minimum door width is 90 cm. This is the solid metal deck in the set, so boxes sit on steel rather than MDF, but the load fields do not agree and we did not test either figure.
Pros
Cons
Best for: You want steel under the boxes, a 90 cm door, and a bay that stays where you built it.
Less suitable: You need wheels, one agreed kilogram, or a cheaper pair of board bays for ordinary boxes.
Specifications
Common questions
What load does SUPEER print?
The bullets say up to 200 kg per shelf and 1,000 kg for the five shelves. A separate field says a minimum weight of 600 kg.
Does it have wheels?
Wheels are not stated. The bullets describe rubber foot pads on the legs.
What are the outside dimensions?
The bullets say H183 × D40 × W90 cm, and the minimum door width is 90 cm.
Harbour Housewares HH-MS4890 is a galvanised pair of 90 × 40 × 180 cm boltless bays at £45.99, with engineered-wood decks and shelf steps of 3 cm. Each unit is stated at 175 kg per shelf, and the bullets quote 875 kg as the total without saying the pair doubles it. Across 421 reviews at 4.2, the dominant praise is value for a garage or shed, and buyers say the second bay is easier once the first is understood. The criticism is that you should not expect industrial racking: thin metal, missing pieces, and awkward first-bay instructions show up in the first 50 reviews. The number-of-items field says 1 while the title, unit count, and pack count say 2. Assembly needs a mallet and no bolts. Galvanised is the finish name on the listing, not proof that the boards survive a wet shed floor.
Pros
Cons
Best for: You want two galvanised frames and a review sample that belongs to this ASIN, for a garage or a shed you will keep reasonably dry.
Less suitable: You wanted industrial racking, or you need the pack-count fields to agree before you order.
Specifications
Common questions
How many racks are in the Harbour pack?
The title and the bullets say a set of two. The number-of-items field says 1, while unit count and number of packs say 2.
What is the stated shelf load?
The bullets say each 5-tier unit holds up to 175 kg per shelf, and they quote 875 kg as the total load capacity.
What do you need to assemble it?
The assembly line says no tools besides a mallet, and no bolts or nails.
The silver SONGMICS pair, model GLR040E02, is two 90 × 40 × 180 cm boltless bays at £42.99, with yellow MDF and shelves that step every 5 cm. The bullets state 175 kg per tier and 875 kg in total, and they do not say that figure doubles because the pack contains two bays. An anti-tip kit is included, and the listing claims a slot-in build with no tools. The star line is 4.1 from 19,832 reviews, and the captured review texts match the black pair, so this is not a separate sample from that ASIN. Reviewers praise the price of a pair and the flat decks, and they criticise slots that are too small, thin MDF, and a flimsy feel against the heavy-duty title. One captured review title calls a unit not fit for purpose and hazardous. The installation field says wall while the mounting type says floor, so plan a freestanding bay and use the anti-tip kit.
Pros
Cons
Best for: You want two board bays for a private garage and you will use the anti-tip kit on a floor-standing frame.
Less suitable: You need metal decks, wheels, or a doorway under 90 cm, or you wanted a review sample that is not shared with the black pair.
Specifications
Common questions
Is the 875 kg figure for both bays?
The bullets say each tier supports up to 175 kg, totalling 875 kg. They do not say that figure is doubled because the pack contains two bays.
Does the box include an anti-tip kit?
Yes. The bullets and the included-components line both name anti-tipping accessories.
How far apart can the shelves move?
The silver listing says shelves adjust every 5 cm. The black pair, a different ASIN, says every 3 cm.
The black SONGMICS pair, model GLR040B02, is two 90 × 40 × 180 cm bays at £45.99, with yellow MDF and shelves every 3 cm. The contents line lists two units, two anti-tip kits, and one manual, and the bullets claim a slot-in build without screws. It prints the same 4.1 from 19,832 reviews as the silver ASIN, including the same names and dates, so do not add the two counts. Reviewers like the flat MDF for boxes, and they complain that the tab slots are too small, the boards are thin, and parts can be missing. A highlight prints model GLR042B01, which is not GLR040B02. A door-width field says 40 cm while the size line is a 90 cm bay, so measure a 90 cm opening. A one-year manufacturer warranty is printed without the terms attached.
Pros
Cons
Best for: You want the black powder coat and 3 cm shelf steps, and you already know the reviews are the same pool as the silver pair.
Less suitable: You are paying the extra £3 because you think 19,832 is a second, independent test.
Specifications
Common questions
How is the black pair different from the silver pair?
This ASIN is model GLR040B02 at £45.99, black, with shelves every 3 cm. The silver ASIN is GLR040E02 at £42.99, with shelves every 5 cm. Both show the same 19,832-review block.
What is in the box?
The included-components line lists two shelving units, two anti-tipping accessories and one instruction manual.
What warranty line is printed?
The listing says a 1-year manufacturer warranty. It does not attach terms.
The DIVCHI five-tier rack is one silver boltless bay, stated as 40 × 80 × 180 cm, at £21.29, with 175 kg per shelf and 875 kg for the unit. Across 666 amazon.co.uk reviews at 4.0, buyers say it goes rigid once the tabs are seated and that it holds tools in a shed. The same reviews call the metal thin and flimsy out of the box, and several say a hard mallet blow bends the uprights. The technical line names aluminium and prints the item weight as 200 g, which is not a plausible weight for this bay, and the bullets never name the deck. A mallet is required and is not in the box. Treat 175 kg as the seller's claim for an evenly spread load, not a figure we tested. Among these listings it is the best value when you want one bay and you will seat every tab lightly.
Pros
Cons
Best for: You want one cheap boltless bay for boxes in a dry garage or shed, and you will tap the tabs home with your own rubber mallet.
Less suitable: You need a named steel specification, a named deck, or a frame the listing says you can split.
Specifications
Common questions
What load does the DIVCHI listing state?
The listing states up to 175 kg per shelf and 875 kg for the unit. It does not show a test report.
How does this boltless rack go together?
The bullets say it clips into place with a mallet, and that the mallet is not included. There are no bolts.
What size is printed?
The technical line says 40 × 80 × 180 cm. The material line says aluminium, and the item weight is printed as 200 g.
The REQUISITE NEEDS RN-332 is one black boltless bay, 40 × 90 × 180 cm, at £23.99, with MDF decks and a stated 175 kg evenly distributed on each of five tiers. The bullets say the frame can be split into a 3-tier and a 2-tier, and that the joints click in with a rubber mallet and no bolts. Across 100 reviews at 3.8, the lowest star line in this set, some buyers say it holds garage storage once it is up. The repeated complaint is flimsy, thin metal: locking pieces come undone as the next joint is tapped, and uprights bend if you hit them hard. Several reviewers describe returns. The material-type field says engineered wood while the bullets name a powder-coated alloy-steel frame and moisture-resistant MDF. The 875 kg total is the five-shelf sum for this one bay, not a result we measured.
Pros
Cons
Best for: You need one 90 cm bay that the listing says you can split, and you will stop if an upright creases.
Less suitable: You want the calmer review record of the £21 bay, or a pair with its own large sample.
Specifications
Common questions
Can this REQUISITE NEEDS bay be split?
The bullets say the frame can be split into a separate 3-tier and a 2-tier. It is sold as one unit.
What load is stated?
Up to 175 kg evenly distributed on each tier, and 875 kg for the bay. No test report is in the listing.
What tool does assembly need?
The listing says a click-lock joint with no nuts or bolts, tapped with a rubber mallet.
Shelf prices, stars and review counts are the amazon.co.uk listings in this comparison, read on 19 October 2026. No bay was lab-tested. The score is 0–100 from four parts, and the highest score is the top pick once. Best value is the highest value-part score that is not the top pick.
Stars
40%Amazon stars out of 40: the listing rating divided by 5, times 40, then rounded. A page with no rating line scores 0 on this part.
Sample
25%Review count out of 25. 1,000 or more reviews score 25, 200 or more score 20, 50 or more score 12, 10 or more score 6, and fewer than 10 score 2. The two SONGMICS pages print the same 19,832-review block. Each still receives the sample points on its own page. The fit note records that the counts are not two samples.
Fit for the rack
25%Up to 25 points for a coherent load line, a deck that matches the room, and reviews that describe real assembly. Conflicts, a shared review pool, thin metal and a missing review text pull this down.
Value in this set
10%Up to 10 points for price against a readable listing. Two usable bays near £43 with a large sample score 10. One bay near £21 with hundreds of reviews scores 8. A pair that repeats the same review block, or a galvanised pair with a review title that says not heavy duty, scores 7. A single rating at the top of the price list scores 2. The value award is not given to the top pick.
Buy the doorway, the deck and a single load line before the largest kilogram in the title. A heavy duty rack here is a freestanding garage or shed bay. It is not pallet racking. 90 cm is the common width. 115 cm and 140 cm will not pass a normal internal door. 875 kg on a boltless listing is five shelves of one bay, not the pair. The two SONGMICS star rows are one review block. A private garage is outside PUWER. A staffed store is not.
A heavy duty rack in this UK set is a freestanding garage or shed bay. It is not pallet racking and it is not a wall bracket. On amazon.co.uk the choice is a cheap boltless frame with a board, a wire rack that may have wheels, or one solid metal shelf. Quality shows up as a size that matches the doorway, a load line you can read without a second conflicting figure, and reviews that still call the uprights straight after a mallet. The largest kilogram in the title is not that check.
175 kg per shelf and 875 kg for five shelves is one bay's sum. SONGMICS and Harbour do not say the pack doubles it. A point load is not the same as a figure that says evenly distributed. None of these lines was tested in a lab.
Both SONGMICS ASINs print 4.1 from 19,832 and the same review text. That is one pool, not two. The black pair costs about £3 more and steps every 3 cm rather than 5 cm. Do not pay the difference because the count looks new.
DIVCHI prints the item weight as 200 g and the material line as aluminium. Mapleyard's material field says wood against alloy-steel wire. Harbour's number-of-items field says 1 against a set of two. Use the size and load lines you can reconcile, and stop if a mallet creases an upright.
Measure the door before the kilogram. Several listings print a minimum door width equal to the bay width. 90 cm is the common boltless width on both SONGMICS pairs, Harbour, REQUISITE NEEDS and SUPEER. DIVCHI is the narrow exception at 80 cm wide, printed as 40 × 80 × 180 cm. The Forthcan 115 cm wire rack prints a 115 cm door, and the 140 cm Forthcan prints 140 cm. A normal UK internal door will not pass either wide wire bay, and many garage side doors will not pass 140 cm.
Read the load as printed, and read it once. The boltless rows repeat 175 kg per shelf and 875 kg for five shelves. That 875 kg is one bay's five-shelf sum. It is not every shelf at once, and it is not doubled because Harbour or SONGMICS sells a pair. SUPEER's bullets say 200 kg per shelf and 1,000 kg for five shelves, while a separate field says 600 kg. Mapleyard states 114 kg per shelf and 567 kg standing, with no moving limit.
Three typical situations, each with a recommendation from this comparison.
You want one bay near £20 for boxes in a dry garage. The DIVCHI five-tier rack is best value at about £21.29, with 4.0 from 666 reviews and a stated 175 kg per shelf. Reviews call the metal thin, the item weight is printed as 200 g, and the deck is not named. Seat the tabs lightly with your own mallet.
You want a galvanised frame and you should not rely on bare MDF in damp air. Harbour Housewares is the galvanised pair at about £45.99, with 4.2 from 421 reviews that are not the SONGMICS block. Galvanised is the finish name. It is not proof the boards survive standing water. Varnish MDF if the shed stays damp.
If the bay is work equipment, HSE INDG412 and HSG76 apply. None of these listings is pallet racking, and none shows a SEMA mark or BS EN 15512. For ordinary boxes the silver SONGMICS pair is the top pick at about £42.99. Do not read 875 kg as the capacity of both bays, and do not add the black pair's review count.
The top pick is the silver SONGMICS pair, GLR040E02, at about £42.99. It scores 85, the highest here: two 90 × 40 × 180 cm bays, yellow MDF, shelves every 5 cm and an anti-tip kit, with 4.1 from 19,832 reviews. That review block matches the black pair. Thin MDF, small tab slots, and a wall-versus-floor field are the deductions. Best value is the DIVCHI five-tier bay at about £21.29. It is the strongest price row that is not the silver pair: 4.0 from 666 reviews and a stated 175 kg per shelf. The metal is thin, the weight field says 200 g, and the deck is not named.
DIVCHI 5-tier boltless rack
About £21.29 for one bay, with 4.0 from 666 reviews, when you will seat the tabs lightly.
