Steel Sheets: Sizes, Thickness Chart, Prices & Specifications

Steel Sheets: Sizes, Thickness Chart, Prices & Specifications<\/h2>

Steel sheets are flat-rolled steel products with thickness from 0.3 mm up to 6 mm, supplied in widths of 1000–2000 mm and lengths of 2000–6000 mm (including the standard 4 × 8 ft and 5 × 20 ft sizes). Sheets are the workhorse material of steel buildings — roof and wall cladding, purlin and girt profiles, decking, tanks, ducting, and enclosures. This page is the complete buying reference from Sino East Steel Group — a direct steel structure manufacturer in Tianjin, China: steel sheet sizes and the full steel sheet thickness chart, material and galvanizing options, 2026 export prices, and the exact way to order steel sheets for your project.

1. What Is a Steel Sheet?

A steel sheet is a flat, thin steel product rolled from hot-rolled or cold-rolled strip. The international convention places sheets at thicknesses up to about 3 mm (hot rolled) or 6 mm (as a practical rolling limit for many sheet applications), above which the product is classified as a plate. Sheets are produced in cut-to-length form or as coil, then optionally galvanized or coated for corrosion resistance. Because they are thin, sheets are formed by bending and roll forming into profiles — corrugated roofing, wall panels, purlins, cable trays, and hundreds of other components.

Steel sheets are supplied to EN 10025-2 and GB/T 3274 (hot-rolled structural sheet), GB/T 708 and EN 10131 (cold-rolled sheet tolerances), ASTM A36 and A1008 for US projects, and EN 10346 for continuously hot-dip coated (galvanized) sheet. Dimensional tolerances follow EN 10051 for hot-rolled and EN 10131 for cold-rolled sheet.

2. Steel Sheet vs Steel Plate: What Is the Difference?

Comparison	Steel Sheet	Steel Plate
Thickness	0.3–6 mm	3–120 mm
Production	Hot/cold-rolled from strip; often galvanized or coated	Hot-rolled from slab; leveled and cut
Typical widths	1000–2000 mm	1000–3000 mm
Best for	Cladding, profiles, ducting, tanks, enclosures	Base plates, gussets, beams, vessels
Surface finish	HR pickled, CR, galvanized, color-coated	Mill scale, blasted/primed on request

If your application needs load-carrying thickness for structural connections, buy plates; for cladding and lightweight members, sheets are the economical choice. See our steel plates page for thickness, weight, and pricing data above 6 mm.

3. Steel Sheet Sizes & Dimensions

Standard steel sheet sizes cover thickness from 0.3 mm to 6 mm, widths from 1000 mm to 2000 mm, and lengths from 2000 mm to 6000 mm. The most common stock sizes worldwide are 1220 × 2440 mm (4 × 8 ft) and 1250 × 2500 mm, with 1500 × 3000 mm, 1500 × 6000 mm (5 × 20 ft), and 2000 × 6000 mm available for larger components. The table below summarizes the series by thickness range.

Thickness Range	Common Widths × Lengths	Typical Applications
0.3 – 0.6 mm	1000–1250 × 2000–2500 mm	Color-coated roofing, ducts, small enclosures
0.8 – 1.5 mm	1000–1250 × 2000–3000 mm	Profiled cladding, tanks, trays
2.0 – 3.0 mm	1250–1500 × 2500–6000 mm	Light structural members, floor plates
3.5 – 6.0 mm	1500–2000 × 3000–6000 mm	Fabricated components, heavy cladding profiles

Thickness tolerances follow EN 10051 for hot-rolled sheet (±0.05–0.12 mm depending on thickness) and EN 10131 for cold-rolled sheet; width and length tolerances are +0/+5 mm on cut sheets. If you need sheets for roll forming, we can also supply in coil form — tell us your profile and required width.

4. Steel Sheet Thickness & Weight Chart (kg per m²)

Indicative theoretical weights for steel sheets, calculated as thickness (mm) × 7.85 kg/m². Galvanized sheet adds roughly 0.1–0.2 kg/m² per side of coating depending on the zinc mass (Z180–Z275). Use this chart for freight, cladding weight, and structural design checks.

Thickness	kg/m²	Thickness	kg/m²	Thickness	kg/m²
0.3 mm	2.4	1.2 mm	9.4	3.0 mm	23.6
0.4 mm	3.1	1.5 mm	11.8	3.5 mm	27.5
0.5 mm	3.9	1.8 mm	14.1	4.0 mm	31.4
0.6 mm	4.7	2.0 mm	15.7	5.0 mm	39.3
0.8 mm	6.3	2.5 mm	19.6	6.0 mm	47.1
1.0 mm	7.9	2.8 mm	22.0	—	—

Worked example: a 4 × 8 ft sheet of 1.2 mm steel measures 2.977 m² and weighs about 9.4 × 2.977 = 28.0 kg — useful for estimating roof cladding loads (typically 5–8 kg/m² including profiles and fasteners).

5. Steel Sheet Material Grades & Coatings

Grade / Option	Specification	Best For
Hot-rolled structural	Q235B / S235JR / SS400 — yield 235 MPa	Fabricated components, light framing
Cold-rolled	DC01 / SPCC / CR1 — improved surface and tolerance	Enclosures, panels, painted parts
High-strength sheet	Q355B / S355JR — yield 355 MPa	Lightweight high-capacity members
Hot-dip galvanized	DX51D / SGCC, Z180–Z275 per EN 10346	Roofing, cladding, outdoor exposure
Color-coated (pre-painted)	Polyester / PVDF over galvanized base	Architectural cladding and roofing
Aluzinc	AZ150 per EN 10346	Coastal roofing, long-life cladding

For building envelopes in humid or coastal regions — much of Africa, the Middle East, and Southeast Asia — specify at least Z275 galvanizing or Aluzinc AZ150 for the longest service life. Mill test certificates (EN 10204 3.1) accompany every batch.

10. Sheet Tolerances, Standards & Surface Quality

Hot-rolled sheet is supplied to EN 10051 with thickness tolerance typically ±0.05–0.12 mm and flatness per class N; cold-rolled sheet follows EN 10131 with tighter thickness and flatness tolerances. Galvanized sheet is produced to EN 10346 with the zinc mass (Z180, Z200, Z275) stamped on the coil or bundle certificate. Surface quality classes A and B apply to cold-rolled sheet, and the mill certificate records the actual coating mass in g/m².

For profiled cladding, confirm the required profile depth and sheet width with your panel supplier before ordering — roll forming consumes width, so profile suppliers quote the effective cover width separately. We can supply cut sheets or coils matched to your profile machine, including slitting to the exact width.

Two points worth confirming at enquiry stage keep your order moving smoothly. First, specify whether you need hot-rolled (mill finish), cold-rolled (smooth, paintable), or galvanized sheet — the price and lead time differ by several hundred US dollars per tonne. Second, state whether your quantities are in pieces or tonnes: a 40 ft container holds roughly 23–25 tonnes of stacked sheets, which is about 1,500–1,800 pieces of 4 × 8 ft in 1.2 mm, and our sales team prepares the loading plan so your freight cost per piece is known before you commit.

11. Packing, Shipping & Delivery

Sheets are packed in steel-banded bundles with protective corner boards and waterproof wrapping for coastal transit, then loaded into 20 ft or 40 ft containers at Tianjin Port. Coils are stowed on A-frames or in cradles to protect edges. Standard export documentation — commercial invoice, packing list, bill of lading, certificate of origin, and EN 10204 3.1 mill test certificates — is provided with every shipment.

Typical transit times: 3–4 weeks to the Middle East (Jebel Ali), 4–6 weeks to East and West Africa (Mombasa, Lagos), 4–5 weeks to Europe, and 3–5 weeks to North America. For full-project shipping details, read our international shipping and installation guide.
