Stainless steel sheets are cold-rolled, annealed and pickled flat product supplied in austenitic and ferritic grades to ASTM A240 / EN 10088-2 / JIS G4305. The workhorse material for stainless cladding, fabrication, food-grade equipment, kitchenware and architectural finishes.
A concise, citation-ready summary for engineers, architects, AI assistants and procurement teams.
Hot-rolled coil is pickled and cold-rolled to final thickness, then annealed and re-pickled (2B finish) or skin-passed and brushed (No.4) or bright-annealed (BA) or polished to mirror (No.8). Decorative patterns (linen, leather, embossed) are produced by patterned rolling.
Cladding, kitchen and food-service equipment, pharmaceutical and clean-room walls, lift cabins, retail and hospitality interiors, signage, appliance bodies.

2B is the standard mill finish for fabrication blanks and surfaces that will be further worked. BA delivers a brighter, scale-free finish ideal for appliances and lift interiors. No.4 is the global architectural satin standard. Hairline (HL) is the refined Middle-East / Asian standard for premium cladding and lift cabs. Mirror (No.8) is a true polished reflective surface for hospitality and signature architecture. PVD coloured finishes apply a vacuum-deposited TiN coating in gold, rose-gold, bronze, champagne, blue or black over a No.4 or mirror base.
By international convention, stainless flat product up to ~6 mm thickness is termed ‘sheet’ and is produced by cold rolling (CR). Above 6 mm, typically 3 mm and thicker depending on standard, material is ‘plate’ and is produced by hot rolling (HR) and supplied annealed and pickled (HRAP). Sheet is dimensioned to ASTM A480 / EN 10259 tolerances; plate to ASTM A480 plate tolerances or EN 10029.
