Technical Specifications and Material Characteristics

Industrial steel grating is primarily manufactured from high-grade carbon steel, often specified as ASTM A36, A1011, or equivalent international standards like EN 10025 S235JR. The material's inherent strength provides exceptional load-bearing capabilities. For enhanced durability and corrosion resistance, galvanization (EN ISO 1461) is a standard post-fabrication treatment.

Key structural components include bearing bars (load-carrying elements) and cross bars (spacing and lateral stability). The configuration of these bars, including their size, spacing, and connection method, dictates the grating's strength, open area, and suitability for specific applications. Riveted grating, in particular, offers a unique blend of rigidity and resilience.

A2: Bearing bar spacing is determined by the required load capacity, clear opening area, and safety factors like preventing objects from falling through. Tighter spacing increases load capacity and reduces open area. Our engineers can assist in calculating the optimal spacing based on your project's specific load requirements and safety standards for floor steel grating.

Q3: What is "steel grating galvanis" and why is it important?

A3: "Steel grating galvanis" refers to steel grating that has undergone hot-dip galvanization, a process where fabricated steel is immersed in a bath of molten zinc. This creates a metallurgical bond, forming a protective, corrosion-resistant coating that significantly extends the life of the grating, especially in harsh or outdoor environments.
