Composite steel grating is composed of checkered plate on sealed surface & steel grating with certain spanning capability.
Composite steel grating is formed of any type of steel grating and checkered plate in different thicknesses. The type JG323/40/100, JG253/30/100 and JG323/60/100 are generally used as base & the checkered plate with 3 mm thickness is used as sealing plate. Sometimes checkered plate with thickness of 4 mm, 5 mm or 6 mm is also used as sealing plate according to customers' requirements.
As thermal stress may cause shape distortion after hot-dip galvanizing treatment, especially when choosing large spacing grating, it's not easy to flatten. So special attention should be paid when choosing grating types.
Composite Steel Grating is an innovative steel grating solution that combines the strength of steel with a unique composite manufacturing process. It offers high load-bearing capacity, anti-slip performance, and multi-functional applications. The load-bearing bars and cross bars are arranged at precise intervals and fixed through welding or compression locking, while the surface is covered with patterned steel plates, steel mesh, or other anti-slip materials. The result is a grating that is not only durable but also visually appealing and suitable for harsh environments.
Key Features of Composite Steel Grating
Composite steel grating supports applications ranging from light pedestrian areas to heavy-duty industrial sites. The load-bearing bars typically have thicknesses from 3–8 mm, with crossbar spacing of 50–100 mm, and patterned steel plates of 3–6 mm thickness. This allows the grating to bear several tons to tens of tons per square meter, making it suitable for a variety of industrial and commercial projects.
Our Composite steel grating can be customized to meet the specific dimensions and shapes required for each project. This reduces on-site splicing, improves installation efficiency, and ensures precise fitment. Since hot-dip galvanizing can cause slight warping, our design team provides expert guidance for customized solutions.
To enhance durability and corrosion resistance, the grating is available with multiple surface treatments, including:
Hot-dip galvanizing (50–100 μm thickness, service life 15–30 years)
Painting
Electrostatic powder coating
Anti-slip surfaces achieve a friction coefficient of 0.6–0.8, ensuring safe operation in both industrial and public areas.
Composite steel grating can be manufactured from a variety of materials based on project needs:
Carbon steel
Stainless steel
Fiberglass
This flexibility allows the grating to withstand harsh environmental conditions, including marine, chemical, and industrial applications.
Our grating can include customized patterned steel plates, which are ideal for residential areas, villa decoration, or other projects requiring both safety and aesthetic appeal.
