Steel Grating designed for mounting clip installation, and flat to be used for the specification model pitch phase; if the welding mode, you must solder joints after grinding, then spray zinc-rich paint, anti-corrosion effect has been reached. Our audit production according to customer requirements of various specifications galvanized grating, welcome to inquire order.
