Frequently Asked Questions

Q: Which bearing bar pitch is most suitable for general industrial platforms?

The 30mm pitch is the most widely used in industrial fields as it offers the strongest resistance to surface lash and heavy loads.

Q: How does hot-dip galvanizing benefit steel gratings?

It creates a metallurgical bond between the zinc and steel, providing a thick barrier that prevents oxidation and rust even in humid or chemical environments.

Q: Can you provide customized cutouts for my specific project drawings?

Yes, we can process gratings according to your specific drawings. Calculation will be based on the total outside size including cutouts and taps.

Q: What is the difference between Plain and Serrated bearing bars?

Plain bars (F) are standard for general use, while Serrated bars (S) provide a non-slip surface, making them ideal for oily or wet environments.

Q: Why is the 60mm pitch recommended for the mining industry?

The 60mm bearing bar pitch combined with 50mm cross bars is specifically designed to solve the problem of mineral splash and accumulation on the plate.

Q: How is the weight of the grating calculated after galvanizing?

Weight increases after the hot galvanizing process: approximately 12% for 30mm pitch, 14% for 40mm pitch, and 16% for 60mm pitch.
