Ekip Steel surface standards

F1

It is also called hot surface or NO:1. It is hot drawn, annealed, matte surface. It is uneven than a 2D or 2B (matte) surface. It is used in areas where visual quality is not important. It has a standard surface for thicknesses above 8mm.

2D

It is cold-drawn, annealed, cleaned, and slightly polished. It has a glossy surface between a matte and a warm surface.

2B

It is also called a matte surface. It is cold-drawn, annealed, cleaned, and slightly polished. It has a standard surface in thicknesses up to 8 mm.

3N

It is the surface obtained by applying the satination process on a cold-drawn matte surface. It is also called the ground surface. They are 3N thick ground surfaces. It is used in decorative areas.

4N

It is the surface obtained by applying the satination process on a cold-drawn matte surface. It is also called the ground surface. They are 4N finer ground surfaces. It is used in decorative areas.

YSB

It is the surface obtained by applying the scrubbing process on a cold-drawn matte surface. It is also called SB (scotch brite) surface. It is used in decorative areas.

ESB

It is the surface obtained by applying the scrubbing and very fine satination on a cold-drawn matte surface. It is also called SB (scotch brite) surface. It is used in decorative areas.

HL

It is the surface obtained by applying the scrubbing and very fine satination on a cold-drawn matte surface. It is also called a hairline surface. It is used in decorative areas.

BA

It is also called glossy surface or 2R. They are cold-drawn, annealed, and polished surfaces. It is used in decorative areas.

8K

It is also called a mirror surface. They are polished and mirror-like surfaces. It is included in the decorative stainless-steel group.

2M

It is also called a dot pattern. It is in the patterned hairline group. It is mostly used in the elevator industry.

5M

It is also called a diagonal square pattern. It is in the patterned hair group. It is mainly used in the elevator industry.

Stainless steel surface standards

EKİP STEEL ASTM EN DIN TYPE OF PROCESS ROUTE SURFACE FINISH EXPLAINATION
F1 1 1D C2/lla Hot rolled, heat treated, pickled Free of scale Usually standard for most steel types to ensure good corrosion resistance; also common finish for further processing. It is permissible for grinding marks to be present. Not as smooth as 2D or 2B.
2D 2D 2D h/lllb Cold rolled, heat treated, pickled, skin passed Smoother than 2B Most common finish for most steel types to ensure good corrosion resistance, smoothness and flatness. Also common finish for further processing. Skin passing may be by tension levelling.
2B 2B 2B h/llc Cold rolled, heat treated, pickled, skin passed Smoother than 2D Most common finish for most steel types to ensure good corrosion resistance, smoothness and flatness. Also common finish for further processing. Skin passing may be by tension levelling.
3N 3 2G o/IV Cold rolled, heat treated, satin polish (rough) Grinded Grade of grit or surface roughness can be specified. Unidirectional texture, not very reflective.
4N 6 2J P/V Cold rolled, heat treated, satin polish (neat) Smoother than ground Grade of brush or polishing belt or surface roughness can be specified. Unidirectional texture, not very reflective.
BA BA 2R m/lld Cold rolled, heat treated, polish surface Smooth, bright, reflective Smoother and brighter than 2B. Also common finish for further processing.
ESB – – – Soğuk çekilmiş, tavlamış,yüzeyi temizlenmiş, satine işlemi uygulanmış Satin Polish Additional specific requirements to a “J” type finish, in order to achieve adequate corrosion resistance for marine and external architectural applications.
YSB 4 2K – Cold rolled, heat treated, pickled, satin polished Satin Polish Additional specific requirements to a “J” type finish, in order to achieve adequate corrosion resistance for marine and external architectural applications.
HL / Hairline – – – Cold rolled, heat treated, pickled, satin polished Satin Polish It is only the surface that is brushed.
8K 8 2P – Polished mirror glossy surface Mirror glossy Mechanical polishing. Process or surface roughness can be specified. Non-directional surface, reflective with high image clarity.
1M / Göz yaşı Desen M2 Patterned Design to be agreed A fine texture finish mainly used for achitectural applications.
2M / Nokta Desen M2 Patterned Design to be agreed A fine texture finish mainly used for achitectural applications.
3M / Micro Nokta Desen M2 Patterned Design to be agreed A fine texture finish mainly used for achitectural applications.
4M / Düz Kare Desen M2 Patterned Design to be agreed A fine texture finish mainly used for achitectural applications.
5M / Çapraz Kare Desen M2 Patterned Design to be agreed A fine texture finish mainly used for achitectural applications.
