Frequently Asked Questions
Plain grating provides a smooth surface for general use, while serrated grating features notched bearing bars to provide superior slip resistance in oily or wet environments.
Hot-dip galvanizing is highly recommended for outdoor and marine projects as it creates a thick, durable zinc layer that prevents corrosion from salt and moisture.
Yes, while we recommend pitches of 30, 40, or 50mm, we can manufacture any specific size according to your technical drawings and requirements.
We primarily use Mild Steel Q235 for industrial strength and Stainless Steel for environments requiring maximum chemical resistance and hygiene.
In civil construction, it is commonly used for road drainage covers, park walkways, trench covers, and maintenance platforms.
We use automatic press welding machines to fuse the bearing bars and cross bars, ensuring high-strength joints that are far more reliable than manual welding.
