Aluminum Steel Bar Grating for Catwalk Deck and Floor Steel Applications

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.

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.

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.

Steel Grating Accessories for Installing
Steel grating accessories are used to install and fix steel grating. They are very necessary. Steel grating accessories have wear resistance, high strength and resistance to stress, rust-proof performance.
Classifications of steel grating accessories:
Saddle clips: A special bent-clip type fastener for removable bar grating panels.
G-clips: A special friction fastener can be used with aluminum, stainless steel and galvanized steel.
Grate fast clips: Grating can be connected by one man only, working from above, without the need to drill the steel or weld on site.
Weld lugs: Weld lugs may be used for installations where grating is subject to removal.
Z-clip: This is the most versatile clip anchor. They are especially helpful in holding down riveted grating.
R-clip: A special formed metal fastener available in various sizes to fit any job.
Countersunk land: It is available for aluminum grating only. Not available for steel.
Anchor block: It can be used to fasten permanent or removable grating panels.

Steel Gratings Types We Supply

GNEE Steel Grating Application

Steel grating are designed and manufactured for various industrial and civil constructions in city road, gardens, yard, airport, railway and industrial engineering.

• Hot dip galvanized steel grating is the best choice for steel platforms in airports. Grating with 30 × 3 mm thick load bearing bars with a pitch of 30 mm and traverse bars at 50 mm or 100 mm is the suitable one.
• Steel grating, with robust design and spanning abilities, is very strong and safe for the support of floors and elevated walkway. It can be used for ceiling, interior decoration, platform aisle, ventilation windows, (Wells), advertising plaque and other construction.
• Widely used in the petrochemical industry, power plants, waterworks, sewage treatment plants, municipal works, sanitation projects in areas such as platforms, corridors, bridge, ditch cover, covers, ladders, fences, rails, and so on.
