Hot Dipped Galvanized Steel Grating Building Materials

Grating Manufacturing Methods

Surface Options (Bearing Bar Type)

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.
