Stainless steel No.4 surface is polished and tempered and rolled with No.150-180 abrasive belt for 2D or 2B products, with better gloss, discontinuous fine grain, streak finer than No.3.
Stainless steel No.1 surface is an industrial grade surface obtained by heat treatment (annealing) and pickling after hot rolling, commonly found on austenitic stainless steels (e.g. 304, 316, etc.).
Stainless steel Hairline finish (also known as Hairline or Straightline finish) is a fine straight line textured finish created by a mechanical grinding process. It is a uniform, continuous, fine-grained surface with a soft, contemporary texture that is often used for decorative purposes.
Stainless steel Chequered surfaces, i.e. patterned plate surfaces. Through a special rolling process, regular pattern patterns, such as lentil,
diamond or round, are embossed on the stainless steel sheet. It significantly enhances the friction and anti-slip performance, commonly used in
stair treads, industrial platforms, ship decks and other slippery areas; at the same time, the unique pattern also gives it a decorative character
and enhances the overall aesthetics
