1. Introduction of steel grating Hot dip galvanized steel grating features (1)Attractive appearance:beautiful outline,silver colour. (2)Optimum water draining: Seepage area reaches 89.3%,which is more larger than cast iron. (3)Hot-dip galvanizing:Hot dipped galvanized surface treatment is professional and can prevent rust effectively. (4)Design of preventing stealing:The cover is connected with the frame by gemel,which ensures protection, safety, and convenient opening. (5)Saving investment:With large span,the cost is lower than that of cast iron when under heavy load.And the replacement expenses in case of theft and crushing will be saved. (6)High strength:With strength:With strength and toughness far higher than those of cast iron,it can be used in the environment with large span and heavy load,such as the wharf and the airport. (7)Many specifications available: The requirement of different environments,loads,spans,sizes and shapes can be satisfied.
