ASTM A709 Grade 100W, A709 Grade 100W Angle steel

A709 Grade 100W Angle steel provides an improved level of atmospheric corrosion resistance over alloy steel without copper, This kind of high strength low alloy structural carbon steel is a used in building bridge projects.

The A709 Grade 100W Angle steel is used for various types of welded, bolted and riveted constructions e.g. steel frame structures, bridges, tanks and containers, exhaust systems, vehicles and equipment constructions. It is recommended to control the corrosion progress of protected parts out of weathering steel exposed to the influence of weather in reasonable time intervals.
