Steel grid panels are commonly used in industry, construction and public areas, and their main functions include:
Anti-slip and drainage: The open hole design of the steel grid helps to drain water and prevent water accumulation and slip accidents. They are commonly used on platforms, steps, walking paths and work areas to provide a reliable non-slip surface.
Bearing and support: Due to the strong structure and high strength of steel grids, they can be used to carry and support heavy equipment, cargo, vehicles and pedestrians. They are commonly used in places such as industrial facilities, Bridges, docks and cargo warehouses.
Ventilation and light transmission: The open hole design of the steel grid can promote air circulation and natural lighting, suitable for environments requiring good ventilation and perspective, such as basements, garages and computer rooms.
Security fence: Steel grids can be used to make security fences and fences to define areas, control access and provide security.
