The best corrugated iron sheets, compared.
Top pick: Harbour Housewares anthracite 14-sheet pack – Highest score at 7.4: classic corrugated wording, 4.6 from 51 reviews, and no clash on pre-drilled holes. Best value: Mondeer dark grey 14-sheet pack – About £53.99 with 4.5 from 257 reviews for a claimed 7 m². Screws are not included, and the sheet is still stated at 0.25 mm. Updated 22.10.2026.
Corrugated iron sheets are galvanised steel panels, wavy or trapezoidal, for sheds, lean-tos, kennels and bin stores. In the UK the usual retail pack is a short single-skin sheet, about 45–46 cm wide, rather than a cut-to-length trade sheet. A trade 13/3 roofing sheet is a different product: one UK seller of that profile recommends 0.7 mm for its own roofing sheet and treats 0.5 mm as cladding. Thickness, claimed face area, profile wording and whether the screws are in the box are the checks that still apply when the brand changes. Those checks are set out in the [corrugated iron sheets buying guide](/hub/diy-supplies/corrugated-iron-sheets/sub/corrugated-iron-sheets-buying-guide). A square-metre figure is length times width times the sheet count, before any lap. Cover width is often not stated, so that figure is not the finished roof. Classic corrugated means a wavy sheet. A listing that also says trapezoidal is not a measured 13/3 pitch. Zinc weight is often missing, so galvanised is not a lifespan. A house roof is out of scope.

Personal buying guide
Question 1 of 2
What are you buying for?
The Harbour Housewares anthracite pack is 14 galvanised sheets at 110 × 46 cm, stated 0.25 mm, for £57.99, with a claimed cover of up to 7 m² before laps. On amazon.co.uk the line is 4.6 from 51 ratings, and this is the listing in the set that says classic corrugated rather than trapezoidal as well. Reviews describe a shed roof, an outdoor kitchen and a rabbit run, and they mention bolts with seal washers, about 85 in one account, even though the bullets do not list screws. The listing says the sheets are not pre-drilled. One review says the screw heads strip, which matters if you drive them into a thin crest. Ridge caps are sold separately: the page says one pack of five caps fits one pack of 14 sheets. It is the top pick here for a small coloured corrugated skin with a consistent listing, not because 0.25 mm matches a trade 0.7 mm roofing sheet.
Pros
Cons
Best for: You want a dark corrugated skin for a small shed, shelter or animal run and you will buy seal screws yourself.
Less suitable: You need screws in the box, a stated 0.7 mm roofing sheet, or a review sample that is not shared with the green pack.
Specifications
Common questions
Can it go on a shed?
The listing names sheds, outbuildings, shelters and animal enclosures. Reviews describe shed roofs, an outdoor kitchen and a rabbit run.
Are the sheets pre-drilled?
No. The listing says they are supplied without pre-drilled holes.
Are fixings in the box?
The bullets do not list screws. Reviews say bolts with seal washers arrived, about 85 in one review, and one review says the screw heads strip.
The green Harbour Housewares pack is listed at the same £57.99, the same 110 × 46 cm sheet, the same stated 0.25 mm and the same claimed cover of up to 7 m² as the anthracite listing. The model is HH-RB4967 rather than HH-RB4966. The title says a 14-pack, while the Number of Packs line says 2, and the listing does not explain the difference. The review text matches the anthracite listing, including 4.6 from 51 ratings, so those stars are not a separate test of the green colour. The listing says there are no pre-drilled holes. Ridge caps are sold separately, and the page says one pack of five caps fits one pack of 14 sheets. Choose green when the colour is the point and you accept that the written reviews are shared. Leave it if you need a star line that belongs only to this ASIN.
Pros
Cons
Best for: You want the green colour at the same stated size as the anthracite pack, and you will buy screws and a ridge yourself.
Less suitable: You are choosing on a review count that is independent of the anthracite pack, or you need one pack-count field.
Specifications
Common questions
How is this different from the anthracite pack?
The listing colour is green and the model is HH-RB4967. Price, thickness, sheet size and the review text match the anthracite listing.
What does the pack-count field say?
The title says a 14-pack. The Number of Packs line says 2. The listing does not explain the difference.
Is a ridge included?
No. The listing says Harbour Housewares ridge caps are sold separately, and that one pack of five caps fits one pack of 14 sheets.
Mondeer’s dark grey pack is 14 sheets at 110 × 46 cm and 0.25 mm for £53.99, with a claimed 7 m² and a packed weight of 15.2 kg. Across 257 amazon.co.uk ratings the line is 4.5, the largest sample in this comparison. Buyers often call the sheet thin, mention bent corners in the box, and still describe a shed or lean-to that was straightforward to fit once they supplied self-tapping roofing screws. Included components are the 14 sheets only. The bullets say there are no pre-drilled holes, while one review says the sheets were pre-drilled and that the description said so. One review says water still got into the shed. It is the best value here because £53.99 is the lowest price among packs with a real review count for a similar claimed area, not because the steel is thicker than the Harbour sheets.
Pros
Cons
Best for: You want the lowest price in this set among packs with a large review count, and you already have roofing screws.
Less suitable: You need the screws in the box, one profile name, or a sheet the listing calls 0.5 mm or 0.7 mm.
Specifications
Common questions
Do the screws come with it?
Included components are 14 roofing sheets. Reviews talk about using self-tapping roofing screws the buyer supplied.
Are the holes already drilled?
The bullets say there are no pre-drilled holes. One review says the sheets were pre-drilled and that the description said so.
What do reviews repeat?
Buyers often mention a thin sheet, bent corners in the box, and a shed or lean-to that was easy to fit. One review says water still got into the shed.
Warmfay’s black pack is 24 sheets at 115 × 45 cm, stated 0.25 mm, for £73.99, and it is the only listing here that states 400 screws and washers in the box. The packed weight is 29 kg. The bullets claim 12.42 m² while the unit-count field says 11.88 m², so you should not treat one figure as the finished roof. On amazon.co.uk the line is 4.0 from 20 ratings. One review says the supplied screws were too small, and another reports rust spots on every panel after about 20 days. A later delivery did not match the first size and pattern, according to one review, while other buyers say the sheets were easy to fit once screwed down. The bullets do not promise pre-drilled holes, and one review says there were none. Buy it when the screw bag is the reason, and weigh the rust report before you treat 24 sheets as a saving.
Pros
Cons
Best for: You want a 24-sheet black pack with fixings named in the box, and you will check those screws on one crest before you fix the whole roof.
Less suitable: You want a large review sample, a single area figure, or a coating you can treat as proven against early rust.
Specifications
Common questions
Are the screws in the box?
Yes. The listing states 400 screws and washers. One review says those screws were too small.
What area is claimed?
The bullets say 12.42 m². The unit-count field says 11.88 square metres. Both figures are on the listing.
What went wrong in reviews?
One review reports rust spots on every panel after about 20 days. Another says a later delivery did not match the first size and pattern. Others say the sheets were easy to fit once screwed down.
The TEOV 24-sheet listing is £67.75 for black panels at the same stated 115 × 45 cm and the same part number C150 as the 12-sheet pack, with the same image URL. The listing claims 12.42 m², which is the 12-sheet claim doubled, again before laps. The bullets say 0.25 mm and the item dimensions again begin 25 × 450 × 1150 mm. Weight is not given. Screws are not listed in the box, and pre-drilled holes are not stated. There is no customer-review line and no review text on the listing. A larger pack at a lower price per claimed square metre is still an unreviewed listing, so it does not outrank the packs that buyers have actually fitted. The material line says galvanised steel in the bullets and zinc plating in the material field.
Pros
Cons
Best for: You are pricing a larger black patch and you will inspect the sheets on arrival because this listing has no reviews.
Less suitable: You want a star line, screws in the box, or a thickness row that agrees with itself.
Specifications
Common questions
How does this relate to the 12-sheet TEOV pack?
Same brand, same part number C150, same image URL, and the same stated sheet size. This listing says 24 sheets and 12.42 m².
Why are there two thickness figures?
The bullets say 0.25 mm. Item dimensions start 25 x 450 x 1150 mm. The listing does not reconcile them.
Are there reviews?
No customer-review line and no review text on the listing.
The TEOV 12-sheet listing is black panels at 115 × 45 cm for £39.89, with a claimed 6.21 m² that matches the stated size times 12 before any lap. The bullets say 0.25 mm, while the item dimensions begin 25 × 450 × 1150 mm, and the listing does not reconcile those figures. Screws are not listed as included, even though the bullets tell you to secure the sheets with screws. The profile is described as trapezoidal grooves and also as corrugated. Part number C150 and the manufacturer field meiyitian also appear on the 24-sheet TEOV listing, which uses the same image URL. This listing has no customer-review line and no review text, so there is no star score beside the £39.89 price. It is the lowest shelf price in the set, and that is not evidence the sheet will stay flat or keep its colour.
Pros
Cons
Best for: You are pricing a small black patch and you will check the steel when it arrives, because this listing has no reviews.
Less suitable: You want a star line, screws in the box, or one thickness figure you can quote.
Specifications
Common questions
How much area does the listing claim?
The listing says 12 panels cover 6.21 m². That matches the stated sheet size times the count, before laps.
Are screws included?
The bullets say to secure the sheets with screws. They do not say the screws are in the box.
What do buyers say?
This listing has no customer-review line and no review text.
Shelf prices, stars and review counts are the amazon.co.uk figures already stored for these six listings. This is not a laboratory test, and there is no snow-load or zinc-weight measurement. Every pack states 0.25 mm, so thickness does not separate them. The score is 0–100 from four parts, and the figure shown beside each pack is that score divided by 10. The highest score is the top pick, once. Best value is the strongest value part among the other listings, once. A copied review block does not count as a second sample.
Stars
35%Amazon stars scaled to 35 points. No rating line scores 0. The green Harbour pack keeps its printed stars in the table, but a copied review block does not earn a second sample.
Review sample
25%A sample of 100–999 reviews scores higher than 30–99, which scores higher than 10–29. No review line scores 0. The green pack’s copied block scores 0 on this part.
Spec honesty
25%Classic corrugated wording scores above a listing that says corrugated and trapezoidal together. A 25 mm row beside 0.25 mm scores lower. Screws named in the box score above fixings that appear only in reviews. A clash on holes, pack count or area scores 0 on consistency, and a rust-in-weeks review is a deduction.
Value
15%Among listings with 30 or more reviews, a lower price per claimed face square metre scores higher. Screws are not added into that sum. A rust-in-weeks review caps this part. No review line stays on the low unreviewed band. Best value is this part, and it is not the top pick.
Buy the gauge and the real cover before the colour. A corrugated iron sheet for a UK shed or lean-to is a short galvanised panel, wavy or trapezoidal, and the retail packs state 0.25 mm. That is not a trade 13/3 sheet at 0.5 mm or 0.7 mm. Check whether screws and a ridge are in the box, and do not treat the title square metres as cover after laps.
A corrugated iron sheet, in the way UK shoppers use the phrase, is a galvanised steel panel with a wavy or trapezoidal profile. People buy it for sheds, lean-tos, kennels and bin stores. The short retail packs are about 45–46 cm wide and about 110–115 cm long. They are single-skin sheet, with no stated anti-condensation fleece, and they are not cut-to-length trade sheets. The thin retail packs state 0.25 mm. Trade 13/3 is a different buy.
A claim near 7 m² or 12.42 m² is length times width times the sheet count. Laps use some of that face. Cover width is not stated, so the title figure is not the finished roof.
Only Warmfay states 400 screws and washers. Harbour reviews mention bolts the bullets omit. Mondeer and TEOV do not list screws as included. Harbour ridge caps are a separate pack.
Every pack here states 0.25 mm. Two TEOV listings also print a 25 mm dimension. A galvanised line is not a zinc weight, a lifespan or a snow load. Plastic and board sold as corrugated iron are a different product.
These packs are 0.25 mm. Trade 13/3 is a different buy: one UK seller recommends 0.7 mm for its own roofing sheet and treats 0.5 mm as cladding. Face claims near 7 m² or 12.42 m² match length times width times count, before laps. Cover width is not stated. Harbour says classic corrugated. Mondeer, TEOV and Warmfay say corrugated and trapezoidal. That is not a measured 13/3 pitch. Warmfay also prints 11.88 m² beside 12.42 m².
Only Warmfay states 400 screws and washers, at about £73.99, with 4.0 from 20 reviews and one report of rust spots after about 20 days. Harbour reviews mention bolts the bullets omit, and ridge caps are separate. Mondeer and TEOV do not list screws. Colours are anthracite, green, dark grey or black. Zinc weight is not stated. On the stored amazon.co.uk prices, about £39.89 to £57.99 is the 12- and 14-sheet band, and about £67.75 to £73.99 is the 24-sheet band.
Three typical situations, each with a recommendation from this comparison.
You want a dark wavy skin for a shed, shelter or run, and you will buy seal screws. The Harbour Housewares anthracite pack is the top pick at about £57.99. It scores 7.4: classic corrugated wording, 110 × 46 cm, stated 0.25 mm, claimed up to 7 m², and 4.6 from 51 reviews. The listing says the sheets are not pre-drilled. It is not a 0.7 mm trade sheet.
You want the lowest price among packs with a large review count for a similar claimed area. The Mondeer dark grey pack is best value at about £53.99. It scores 7.3, with a claimed 7 m² and 4.5 from 257 reviews. Screws are not included. Buyers mention a thin sheet and bent corners. The profile line says both corrugated and trapezoidal.
You want the fixings written into the included list. The Warmfay black 24-sheet pack at about £73.99 states 400 screws and washers, with a packed weight of 29 kg and 4.0 from 20 reviews. One review says the screws were too small, and one reports rust spots after about 20 days. The listing prints both 12.42 m² and 11.88 m².
The top pick is the Harbour Housewares anthracite 14-sheet pack at about £57.99. It scores 7.4, the highest here: classic corrugated wording, 4.6 from 51 reviews, and a listing that says the sheets are not pre-drilled. Screws are not in the bullets. Best value is the Mondeer dark grey 14-sheet pack at about £53.99. It scores 7.3, with 4.5 from 257 reviews and a claimed 7 m². The screws are not included, and the stated thickness is still 0.25 mm. Warmfay at about £73.99 is the only pack that states 400 screws, with 4.0 from 20 reviews and one rust-in-weeks report. The two TEOV packs have no review line on the listing.
