Core Application Areas & Typical Scenarios

Steel grating (also known as bar grating) is a metal component formed by cross-welding flat steel and twisted square steel at specific intervals. It boasts core advantages, including high strength, anti-slip performance, ventilation, light transmission, and ease of installation/maintenance, making it widely used in industrial production, infrastructure, construction engineering, and other fields.

1. Industrial Plants & Workshops

Platforms & Walkways: Operating platforms for factory equipment, maintenance walkways, and stair treads (e.g., chemical workshops, machinery processing plants, steel mill converter workshops). Steel grating's high strength can withstand heavy equipment and personnel loads (conventional load capacity ≥ 3kN/m²), while its anti-slip surface (serrated/anti-slip flat steel) prevents slips caused by oil or water stains. The ventilated and light-

2. Infrastructure Projects

Roads & Bridges: Bridge sidewalks and maintenance passages: Used for pavement of highway and railway bridge sidewalks, offering excellent anti-slip performance and reducing rainwater accumulation (e.g., cross-sea bridges, urban overpasses);

Tunnel ventilation gratings: Ventilation opening gratings on tunnel ceilings/walls, balancing ventilation and safety protection (preventing debris from falling), suitable for long-distance highway and railway tunnels.

Municipal Engineering:Urban pipe network manhole covers: Covers for rainwater wells, sewage wells, and gas wells in municipal roads, parks, and residential areas. Steel grating manhole covers have strong load-bearing capacity (heavy-duty covers can withstand ≥ 250kN, suitable for vehicle rolling), anti-theft design (lockable), and are not easily clogged (hollow structure facilitates drainage and cleaning);

Sewage treatment plants: Aeration tank gratings, sedimentation tank walkways, and sludge treatment workshop platforms.

Ports & Terminals: Terminal loading/unloading platforms, approach bridge walkways, and anti-slip pedals for ship berths. High-strength steel grating can bear loads from container cranes and heavy trucks, and anti-corrosion treatment (e.g., hot-dip galvanizing + spraying) resists seawater erosion (e.g., coastal ports, inland river terminals).
