Commodity name: SMA400BW steel

Product introduction

SMA400BW is a weather resistant steel created by alloying copper, chromium and nickel. SMA400BW has added phosphorous which makes the material best suited for gas flue applications and for aesthetic facias.

The specifications:
Thickness: 3mm--150mm
Width: 30mm--4000mm
Length: 1000mm--12000mm
Standard: ASTM EN10025 JIS GB
