Steel grating is a load-bearing metal product made of bearing bars and cross bars, widely used for industrial walkways, shipyard platforms, trench covers and offshore working floors. Its high strength, anti-slip and drainage advantages make it irreplaceable for marine and heavy industry projects. For shipyard and offshore environments, salt spray corrosion brings strict requirements on raw material and surface treatment. Choosing proper steel grating directly affects project safety and service life.

Product Overview of Steel Grating

Steel grating is fabricated by pressure welding steel bearing bars and twisted cross bars. Hot-dip galvanizing is the most common anti-corrosion treatment. Different bar height and thickness determine the load capacity. Hengyueda supplies shipyard grade steel grating, heavy duty platform grating and trench cover grating with full test reports for marine and industrial customers.

Shipyard environment contains high salt fog, humidity and frequent mechanical impact. Ordinary light galvanized grating will rust quickly. Shipyard projects usually require heavy hot-dip galvanizing with zinc coating over 85μm. Engineers also need to calculate span and load. Longer span needs higher bearing bar to avoid bending under worker or equipment weight. Anti-slip serrated steel grating is strongly recommended for wet marine platforms to reduce fall risks.

Many buyers make mistakes by only comparing unit price. Thin bearing bar grating may save initial cost but deform under load and cause safety hazards. Qualified steel grating suppliers can provide load test data and factory certificates. Hengyueda supports custom panel size, serrated surface and different bar spacing for shipbuilding and industrial platform projects.

Typical Application Scenarios

• Shipyard workshop walkway and offshore working platform
• Chemical plant, power station and oil refinery platform
• Drainage trench cover, stair treads
• Parking area, heavy equipment access floor
