Corten B Angle steel ,ASTM CortenB steel ,CortenB Atmospherical corrosion steels.

Posted:2015-11-30 01:13:03

ASTM CortenB , a weather resistant steel which is better suited for heavy and load bearing structures. The material forms its own protective layer when exposed to atmospheric elements. Essentially, the top layer corrodes which then protects the steel beneath it. The natural finish does not normally require any form of maintenance such as painting, which makes the material a highly cost effective alternative to other structural steels.

Corten B angle Steel Application

In most circumstances, Corten B steel for steel atmospheric corrosion resistance is better than carbon structural steel plate and sheet containing copper or not in essence. When fully exposed to the atmosphere, Corten B angle section steel can be widely used in many cases under bare (uncoated) condition ,so corten B steels are used for various types of welded, bolted and riveted constructions e.g. steel frame structures, building cladding, metal sculptures , chimneys, bridges, tanks and containers, exhaust systems, vehicles and equipment constructions.
