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.
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.
Industrial field
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.
