8. Professional FAQ: Galvanized Grating Solutions

Q1: What steel grade is typically used for galvanized steel grating?

A1: Low-carbon mild steel such as Q235 or Q195, or international equivalents like SS400, are most common, providing an optimal balance of strength, ductility, and weldability.

Q2: What are the standard bar size and mesh pitch for galvanized grating?

A2: Main bar sizes range from 25×3mm to 50×5mm; common mesh pitches include 30×100mm, 40×100mm, and 50×100mm.

Q3: Which international standards govern grating galvanized quality?

A3: Key standards include ISO 1461 (hot-dip zinc coat), ISO 9001 (quality management), EN 1090 (fabrication), and ANSI/NAAMM MBG531 (North America).

Q4: How does load-bearing capacity differ among various galvanized grating products?

A4: Load capacity depends on bar size, steel quality, and weld strength. Standard 30×5mm bar, 30×100mm mesh, can usually support >4000kg/m² (per ISO 14122).

Q5: How is the galvanizing thickness controlled and tested?

A5: Each batch is inspected post-galvanizing using non-destructive digital gauge. Thickness (usually 85-110μm) adheres to ISO 1461. Test report provided upon request.

Q6: What is the expected service life of galvanized steel grate in outdoor industrial use?

A6: Generally 30–40 years, influenced by pH, chloride exposure, and traffic. Per ISO 9224, hot-dipped grating maintains structural strength for decades even in C3/C4 corrosion atmospheres.

Q7: Can galvanized grating be cut and installed on-site?

A7: Yes. Gratings can be custom-cut with proper tools. Post-cutting, edges should be re-galvanized using cold-galv spray to maintain anti-rust performance (per ASTM A780).
