Hot-DIP Galvanized Steel Grating with 3mm-7mm Thickness and 30mm-40mm Pitch for Heavy Duty Applications

Welded Grating
The most commonly used and economical design suitablefor most industrial applications. Manufactured by weldingthe bearing bar and cross bar intersection, typically withautomated forge welding equipment or professional manualwelding.Available in carbon steel or stainless steel.
Dovetail Pressure Locked:
Insert the cross bar into the pre-punched bearing bar andhydraulically deform it to lock it in place. The cross bar hereis usually a straight plate shaped like a bearing bar.
Swaged Pressure Locked:
Assembled by inserting pre-punched bearing and cross barsinto an "egg-crate" configuration and deforming the crossbars under intense hydraulic pressure. Available in all mate-rials and ideal for architectural and ornamental applications
Welded Swaged Pressure Locked:
It is an upgraded version of the swaged pressure lockedEach intersection is manually welded once to make it stron-ger and can withstand more loads.

Surface Treatment
We provide four finishes for anti-corrosion treatment of carbon steel bar grating:
Black / Bare Steel: No finish, life is very short, but the price is the cheapest.
Painted Coat: The anti-rust effect is general and can be any color.
Electro-galvanized: A small amount of zinc coating, easy to cause slight corrosion in humid environment.
Hot-dip galvanized: The most commonly used method to provide the best anti-rust effect, strictly in accordance with ASTM A123 or GB/T 13912-2002.
