Description of Manufacturing:

    The grating with inserted and fixed vertically by twin flat bar is made by steel CNS2473.  After the steel grating is formed, the hot dip galvanization treatment usually comes as the first finishing process.  The thickness of the galvanization is required up to 610 g/m2, and the fixing pins and bolts as well as plate envelop on the steel grating are also required for the purpose of anti-theft design.  Most importantly, the certificate of Manufacturing and Certificate of Guaranty are required to be submitted by subcontractor before construction begins.
