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.
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.
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.
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
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
Due to discoloration during welding and manufacturing, stainless steel bar grating usually requires a second cleaning:
Stainless steel pickling passivation:
Soak the entire stainless steel grating in the stainless steel pickling passivation solution, provide a uniform silver-white matte surface.
Stainless steel electrolytic polishing:
The stainless steel grating is immersed in the electrolytic solution that is energized and heated to 75 degrees for 1-3 minutes, can obtain a bright stainless steel surface.
