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.
2. Bearing Bar Type:
Flat Bar Grating; Serrated Bar Grating ; I Bar Grating (include flat bearing bar and serrated bearing bar)

INSTALLATION OF STEEL GRATING:
1. There are two ways of installation for grating. One way is by welding and other is by using installation fastener. The welding method is suitable for those parts which will be fixed forever,such as platforms for equipments,while the method by using installation fastener has the properties of easy to assemble and disassemble and of preventing destroying the zinc layer.
2. Installation fastener is suitable for all types of gratings. It is made of up-fastener,down-fastener and inside cylinder bolt M10.
3. Welding method is angle welding at the first bearing bar of every corners on the grating.Welding seam of which is not less than 20mm length and not less than 3mm height.
4. It at least needs four sets of installation fasteners on every grating to fix.You had better install more fasteners on the supportable construction when the span is larger.
5. We can supply stainless steel installation fastener to satisfy our customer’s requirements.
6. Please indicate clearly the type,quantity and material when you purchase installation fastener.
