Frequently Asked Questions

Q: Which material is best for coastal environments?

For coastal areas, we recommend Hot-Dip Galvanized Steel (ASTM A123) with 85–100 µm zinc coating or Stainless Steel 316L, both of which offer superior salt spray resistance (1,500+ hours).

Q: Does your grating meet OSHA safety standards?

Yes, our products are designed to meet OSHA 1910.23 standards, featuring SlipGuard designs and compliant toe plates to eliminate tripping hazards in industrial catwalks.

Q: What is the difference between Electric Resistance Welding and Press-Locked?

Electric Resistance Welding provides uniform crossbars for consistent load distribution, while Press-Locked construction interlocks bearing bars for zero-slip performance, ideal for refinery treads.

Q: Can you provide custom sizes for tight industrial spaces?

Absolutely. While we offer standard 1m x 6m panels, we provide precision laser-cutting (±0.5 mm) for custom configurations to ensure seamless alignment in modular platforms.

Q: How do you test the load-bearing capacity of the grating?

We perform rigorous Load Deflection Tests according to EN 1990, validating that deflection remains ≤L/200 even under 1.5x the design load (e.g., 30 kN/m²).

Q: Is your stainless steel grating suitable for food processing?

Yes, our 304 stainless steel grating with hygienic electropolish (Ra ≤1.6 µm) is fully FDA compliant and ideal for food-grade and pharmaceutical facilities.
