I Shape Steel Grating Factory - Plain and Serrated Options

I Type Steel Plate Surface Treatment

Hot galvanizing, cold galvanizing, painting, dipping rust oil, no treatment (general stainless steel without treatment).

I Type Steel Plate Production Method

I type steel plate is composed of load flat steel and horizontal bar arranged according to a certain spacing of longitude and latitude, using 200 tons of hydraulic resistance welding automation equipment welding into the original plate, after cutting, opening, rimming and other processes processed into customer requirements.
