Description
Hot-dip galvanized steel grating has strong impact resistance, strong corrosion resistance and heavy load capacity, elegant and beautiful, and has excellent performance in municipal subgrade and steel platform construction projects. The high cost performance is the construction project of the hot galvanized steel lattice plate widely used in the pavement of the old and new subgrade.
It has long service life is, it is generally within the range of 40 years -50 years. The hot-dip galvanized steel plate is a very good steel frame structure and bearing platform without the participation of the destructive factors.
