1. Brief Introduction of press locked steel gratings

With Press-Locked Grating the cross bars and bearing bars are notched and pressed together through a high pressure manufacturing process. The result is a bi-direction flush surface that assures a firm, rigid connection and makes it aesthetically appealing for architectural applications. It is available from stock in twp bearing bars heights, in plain or corrosion-resistant galvanized steel, or aluminum. A variety of other bar heights, bar spacings and materials is available by special order.
