Ordinary Surface
Galvanized Surface (hot-dip galvanizing thickness ≥ 85μm, service life up to 15-20 years),
Black Oil Surface
Construction: Served as frame beam and column and high-rise office, apartment, shopping mall and other building construction; also used in building industrial plant and crane beam.
Bridge Applications: Used for small- and medium-span highway and railroad bridges in the deck system and in the substructure.
Municipal & Special Structures: Employed in subway stations, city pipeline carriers, tower crane bases, and temporary construction strut work.
Industrial Plant Supports: The vertical support beam is a critical element for stability, that enhances the framework of an industrial building by providing stability in both the vertical and horizontal planes.
