ASTM A588GR.B I BEAM STEEL

A588 Grade B I Beam steel is for high strength low alloy structural steel with 345Mpa minimum yield point to 100mm thickness.When propertly exposed to the atmosphere, A588 Grade B I Beam steel is suitable for many applications in the bare condition. A588 Grade B I Beam steel could be produced in 200mm in our Steel mill.
A588 Grade B I Beam Steel Application
A588GrB I Beam steel is widely used to manufacture mills. general building, all kinds of mining equipment, mining track, excavators, loaders, bulldozers, variouscranes, mining machinery and equipment such as hydraulic supports and other structural parts.

ASTM A588 Grade B I Beam steel is categorized as Alloy Steel. A588 Grade B steel is intended primarily for use in welded bridges and buildings where savings in weight or added durability are important. The atmospheric corrosion resistance of this uncoated steel in most environments is substantially better than that of carbon structural metal steels with or without copper addition. When properly exposed to the atmosphere,A588 Grade B I Beam steel is suitable for many applications in bare condition without any coating.
Shanghai Katalor Enterprises Co., Ltd is a A588 Gr B I Beam steel supplier, we can offer High quality A588 Gr B I Beam steel and pretreatment of the advanced equipment. If you want to know more about A 588 Gr B I Beam steel, please contact us.
