Heavy steel grating is a type of steel grating with enhanced load-bearing capacity, typically used in scenarios involving heavy loads.
It is fabricated by pressure welding, manual welding, or press-locked welding of load-bearing flat steels and cross bars arranged at specific intervals. Its surface is usually treated with hot-dip galvanizing to enhance corrosion resistance.
Features of Heavy Steel Grating
-
Super strong bearing capacity
Gratings can withstand large-tonnage heavy equipment and vehicles, suitable for dynamic and static loads.
-
Solid structure
Through high-strength welding or pressure welding process, it has extremely high strength and stability, which can effectively prevent deformation.
-
Strong durability
Hot-dip galvanizing makes it with good corrosion resistance and long service life, especially suitable for humid and highly corrosive environments.
-
Anti-slip and safety
Heavy duty steel grating can be made of serrated surface, which has excellent anti-slip performance and is especially suitable for oily or humid areas.
-
Good ventilation and drainage
The grating’s opening structure can not only maintain good ventilation and lighting effects, but also quickly drain water and reduce water accumulation problems.
-
Customizability
Flexibly adjust the specifications, spacing, shape and surface treatment of the load-bearing flat steel according to the scene requirements.
Application Fields of Heavy Duty Steel Grating
-
Setor industrial
Heavy equipment platform: such as equipment maintenance platform in petrochemical plants, power plants, and metallurgical plants.
Corridor: Passages in industrial plants used to carry pedestrians and small vehicles.
-
Traffic and transportation
Bridge pavement: as a load-bearing plate in bridge structures.
Ports and docks: used to bear the load of heavy cranes and trucks.
-
Municipal and civil engineering
Drainage cover: heavy-duty drainage ditch cover is suitable for high-load areas such as urban roads, parking lots, and airports.
Underground pipeline maintenance platform: large bearing capacity and long service life.
-
Mining and energy field
Mining facilities: heavy-duty load-bearing platforms used in mining, stockpiling yards and other areas.
Power plant equipment area: large equipment operating platform or maintenance walkway.

Design and installation considerations
-
Design load
Clarify the dynamic or static load requirements during the design stage and select the appropriate flat steel thickness and spacing.
-
Installation method
Welding or clamping can be used. Welding is more suitable for permanent installation, and clamping is convenient for later maintenance and disassembly.
-
Size customization
Customize the appropriate steel grating specifications in advance according to the size of the actual installation site to reduce secondary processing.
-
Anti-slip design
For ramps and wet areas, it is recommended to choose toothed steel grating to increase friction.
