Sheets and plates are flat-rolled products used for fabricated equipment, vessels, tanks, structures, liners and machined components. They are chosen by grade (corrosion, temperature or wear resistance), thickness and size, and – for stainless in particular – by surface finish, which affects both appearance and cleanability.
We supply hot and cold rolled material from stock and to order, cut to your dimensions: full sheets, plates, coils, strips, circles and profile-cut blanks, with mill test certificates traceable to the heat number.
The names are defined by thickness and width. ASTM A480 gives the following classification for stainless flat products.
| Product | Thickness | Width | Typical Use |
|---|---|---|---|
| Sheet | Under 4.76 mm (3/16") | 600 mm (24") and over | Cladding, panels, kitchen & dairy equipment, light fabrication |
| Plate | 4.76 mm (3/16") and over | Over 250 mm (10") | Vessels, tanks, structures, machined parts, liners |
| Strip | Under 4.76 mm | Under 600 mm | Components, pressings, narrow-width fabrication |
| Coil | Sheet or strip thickness | Slit to width | Continuous feed for pressing, roll forming, tube making |
The rolling route decides the thickness range, tolerances and the finish you can achieve.
Rolled above the recrystallisation temperature, then annealed and pickled. Economical for heavy sections, with a matte No.1 surface and wider thickness tolerances.
Reduced at room temperature and annealed, giving closer thickness tolerances, better flatness and a smoother, brighter surface suitable for polishing.
Supplied in coil form for continuous processing, or slit to the exact width you need for pressing, roll forming and component manufacture.
Patterned plate for anti-slip flooring, perforated sheet for screens and guards, and circles or blanks cut for pressing, dished ends and flange facings.
Finish affects appearance, cleanability and corrosion behaviour. Designations follow ASTM A480 / EN 10088-2.
Hot rolled, annealed and pickled. Dull, matte and slightly rough – the standard finish for plate.
Vessels, tanks, structural, high-temperature workCold rolled, annealed and pickled. Uniform matte grey with good paint and coating adhesion; suits deep drawing.
Pressings, deep-drawn parts, painted work2D followed by a light skin pass on polished rolls – smooth, semi-reflective. The most common general-purpose sheet finish.
General fabrication, equipment, chemical plantBright annealed in a controlled atmosphere, so no scale forms – highly reflective, smooth and easy to clean.
Architectural, pharma, hygienic, decorativeUniform directional abrasive finish, typically 150–180 grit. Hides fingerprints and scratches better than bright finishes.
Kitchens, dairy, food equipment, lifts, façadesLong, continuous fine brush lines running the length of the sheet – popular for architectural cladding and lift panels.
Cladding, elevators, signage, interiorsProgressively polished and buffed to a reflective, almost image-clear surface with no visible grit lines.
Decorative panels, columns, display, reflectorsRaised diamond or tear-drop pattern rolled into the surface for grip underfoot, in stainless, carbon steel and aluminium.
Walkways, stair treads, platforms, vehicle bodiesPVC film protection is applied on polished and mirror material to prevent handling marks. Other finishes – electropolished, embossed, etched, coloured PVD – can be arranged on request.

How flat products are made – and why the route determines thickness, tolerance and finish.
Steel is melted and refined (AOD / VOD for stainless) and continuously cast into slabs. Each melt carries a heat number that stays with the material to delivery.
The reheated slab is rolled down to plate or hot band on a reversing or Steckel mill, controlling temperature to develop the required structure.
Solution annealing (typically 1040–1120 °C for austenitic grades) followed by quenching, then pickling to remove scale and restore the passive layer – producing the No.1 finish.
Cold reduction on a Sendzimir or tandem mill gives closer tolerance and better flatness; a light skin pass on polished rolls produces the 2B surface, or bright annealing produces BA.
Roller levelling corrects flatness; abrasive belts produce No.4, hairline or mirror finishes, with PVC film applied to protect the surface.
Material is cut to size, inspected for dimensions, flatness and surface, marked with grade and heat number, then packed for dispatch.

It is a matter of thickness and width. Under ASTM A480, stainless material under 4.76 mm (3/16") thick and 600 mm or wider is a sheet; 4.76 mm and over, wider than 250 mm, is a plate. Narrow, thin material is strip. Sheets are usually cold rolled with a bright finish; plates are usually hot rolled with a No.1 finish.
2B is the general-purpose cold rolled finish: smooth, semi-reflective and economical. BA (bright annealed) is more reflective and easier to clean, used in pharma, hygienic and decorative work. No.4 is a brushed satin finish that hides fingerprints and scratches, widely used for kitchen, dairy and architectural surfaces.
Yes. We supply cut-to-size plates, circles, rings and profile-cut blanks, from a single piece upwards. Send your cutting list or drawing – supplying material ready to use saves you handling, scrap and machine time.
Yes – SA 516 Gr. 60/70 and SA 387 for boilers and pressure vessels, and 400/500 HBW class abrasion-resistant plate such as Hardox for liners, buckets and chutes, along with SAILMA high-tensile structural plate.
Yes. Straight-beam ultrasonic examination to ASTM A578 (or A435) can be arranged for pressure-vessel and heavy-plate applications, with the report supplied alongside the mill test certificate.
Weight per square metre equals thickness in mm × density (7.85 for carbon steel, 7.93 for SS 304, 2.70 for aluminium). Multiply by the area in m². For example, a 2000 × 1000 × 10 mm SS 304 plate weighs 2 m² × 79.3 = 158.6 kg. Our weight calculator does this for any material.
