Product Description

Product Description

Steel Grating

Hot DIP galvanized steel grating has three kinds of steel gratings, they are Plain Style Steel Grating, Serrated Style Steel Grating and I Bar Type Steel Grating.

 

They are widely used in steel structure platforms, stair treads, sidewalks, drainages and well covers etc.

 

We can design and manufacture standard steel grating and in customized shapes per client's requirements.

Grating Manufacturing Methods

Welded Grating:

_{The most commonly used and economical design suitable
for most industrial applications. Manufactured by welding
the bearing bar and cross bar intersection, typically with
automated forge welding equipment or professional manual
welding. Available in carbon steel or stainless steel.}

Dovetail Pressure Locked:

Insert the cross bar into the pre-punched bearing bar and
hydraulically deform it to lock it in place. The cross bar here
is usually a straight plate shaped like a bearing bar.

Swaged Pressure Locked:

_{Assembled by inserting pre-punched bearing and cross bars
into an "egg-crate"configuration and deforming the cross
bars under intense hydraulic pressure. Available in all mate-
rials and ideal for architectural and ornamental applications.}

Welded Swaged Pressure Locked:

_{It is an upgraded version of the swaged pressure locked.
Each intersection is manually welded once to make it stron-
ger and can withstand more loads.}

 

Customized Size

Material:

Excellent material, strong and durable.

Our steel grating is made of high-quality galvanized Q235 steel, ensuring excellent durability and corrosion resistance. It can withstand long-term outdoor use without rusting or corroding, ensuring a long lifespan.

Strength:

High strength, low damage. It can efficiently handle vehicle and pedestrian traffic while maintaining excellent drainage performance. Pressure welding structure of the product makes it strong and durable. Cars crushing the driveway drain cover will not cause any deformation or denting, making it very safe.

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.
