Composite Steel Grating

Composite steel grating is a heavy-duty metal grating that combines a load-bearing steel grating base with a checkered plate top surface. The grating base is manufactured by welding flat steel bars and twisted cross bars together, while the checkered plate is welded on top to create a solid, slip-resistant walking surface. This composite construction delivers the strength and rigidity of steel grating together with the closed, anti-slip surface of checkered plate, making it ideal for areas where small objects must not fall through and where a solid walking surface is required.composite steel grating.

Frequently Asked Questions

What is composite steel grating used for?

Composite steel grating is used for industrial platforms, walkways, stair treads, drainage covers, trench covers, and structural flooring where a solid, slip-resistant surface is required and small objects must not fall through.

What is the difference between composite steel grating and standard steel grating?

Standard steel grating has an open pattern that allows liquids and debris to drain through. Composite steel grating adds a checkered plate top surface, creating a closed walking surface that prevents small objects from falling through while still providing structural strength.

What flat bar sizes are available?

Standard flat bar widths include 20mm, 25mm, 30mm, 32mm, 35mm, 40mm, 50mm, and 60mm. Custom sizes are available on request.

What spacing options are available?

Flat bar spacing options include 20mm, 30mm, 40mm, 50mm, and 60mm, with a minimum center-to-center spacing of 15mm. Cross bar spacing is typically 50mm or 100mm, with custom widths such as 30mm, 40mm, 60mm, and 80mm also available.

What checkered plate thicknesses are available?

Checkered plate thickness ranges from 3mm to 5mm, depending on load and wear requirements.

What materials are available?

Composite steel grating is available in carbon steel, galvanized steel, stainless steel, and aluminum to suit different environments and load requirements.

What is the lead time for bulk orders?

Standard lead time is 15 to 25 days after deposit, depending on order quantity and customization.

What payment terms do you accept?

We accept T/T, L/C, and other negotiable terms. Our sales team will provide detailed payment information with your quotation.

Heavy-duty steel grating

Heavy-duty steel grating is a high-load-bearing metal grating designed for the most demanding industrial and infrastructure applications. It is manufactured using thicker and wider load-bearing flat steel bars, with a thickness of 6mm or more and a width of 50mm or more, welded or pressure-locked with cross bars to form a rigid, one-piece structure. Heavy-duty steel grating is capable of supporting loads exceeding 10 tons, making it ideal for heavy traffic areas, large-span platforms, and critical structural flooring.

FRP Grating

FRP grating, also known as fiberglass reinforced plastic grating, is a high-strength, corrosion-resistant composite grating manufactured from glass fiber rovings and thermosetting resin. Unlike steel grating, FRP grating does not rust, does not conduct electricity, and is not affected by most chemicals, making it the preferred choice for chemically aggressive, humid, and electrically sensitive environments. It is widely used for walkways, platforms, stair treads, trench covers, and structural flooring in chemical plants, water treatment facilities, marine environments, and food processing plants.

Trench cover

Trench cover grating is a heavy-duty metal grating specifically designed to cover drainage trenches, cable channels, and service ducts while supporting pedestrian and vehicular traffic. Each cover is manufactured by welding load-bearing flat steel bars and twisted cross bars together to form a rigid, open, and slip-resistant surface. The open pattern allows water, oil, and debris to drain freely into the trench below, preventing surface flooding and keeping walkways and traffic areas clean and safe.

Stainless Steel Grating

Serrated steel grating is a high-strength, slip-resistant metal grating manufactured with serrated edges on the load-bearing flat steel bars. The serrated profile creates additional grip points on the top surface of each bar, delivering superior traction in wet, oily, icy, or contaminated conditions. This makes serrated steel grating the preferred choice for industrial platforms, walkways, stair treads, drainage covers, and structural flooring where standard smooth grating may not provide sufficient slip resistance.
