Product Description

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.

Different Types

Surface Finish

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.

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.
