Steel bar grating with high strength and firm structure is made up of carbon steel, aluminum steel, or stainless steel. According to the manufacturing methods, it can be divided into four types: welded, press-locked, swage-locked, and riveted gratings. According to the surface shapes, it can be divided into smooth and serrated gratings. With various styles and sizes for choice, steel gratings are widely used in everyday life, such as stair treads, walkways, platforms, floors, various covers, wheeled equipment, security screens, heavy-duty constructions, and so on.

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 materials and ideal for architectural and ornamental applications.

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.
