Key Advantages

Extreme Load Capacity

Designed specifically for heavy vehicles and forklifts, providing maximum impact resistance and structural stability.

Superior Corrosion Resistance

Hot-dip galvanized coating according to GB/T13912-2008 ensures long-term protection in harsh environments.

Anti-Slip Traction

Recommended toothed steel lattice patterns provide enhanced friction and safety for pedestrian and vehicle traffic.

Precision Engineering

Pressing lock manufacturing effectively prevents bearing flat steel deformation and tilt instability.

Refined Finishing

All spatter, welding slag, and burrs are removed; corners are polished to eliminate sharp edges for safety.

Load Banding Security

Welded band bars distribute heavy loads evenly across the panel to minimize potential distortion.

Frequently Asked Questions

Q: What makes "Heavy Duty" steel grating different from standard grating?

Heavy Duty grating utilizes thicker bearing bars and reinforced load banding to support extreme weight, such as trucks and forklifts, whereas standard grating is for pedestrian or light-duty use.

Q: Which galvanizing standard is used for these products?

We strictly follow the GB/T13912-2008 hot-dip galvanizing standard, ensuring a zinc layer of at least 610g/㎡ for steel thicker than 5mm.

Q: How do I determine the correct bearing bar width for my project?

Selection depends on the clear span and the expected safe uniformly distributed load (U). We provide detailed load/deflection tables to help you choose the optimal specification.

Q: Can these gratings be used in corrosive environments?

Yes, the high-quality hot-dip galvanizing or the option for stainless steel (0Cr18Ni9) makes these products ideal for corrosive industrial settings.

Q: What is the purpose of the "pressing lock" method?

The pressing lock method prevents the bearing flat steel from tilting or shifting under load, ensuring the panel remains flat and stable over time.

Q: Are the edges safe for workers during installation?

Absolutely. All semi-finished parts undergo rigorous processing where spatter and burrs are removed, and all corners are polished to ensure there are no sharp edges.
