Frequently Asked Questions
Smooth grating is ideal for standard walkways, while serrated grating provides a textured surface that significantly increases grip, making it essential for areas prone to oil, water, or ice.
For most heavy-duty applications, ASTM A36 or Q235 carbon steel is recommended due to its excellent strength-to-weight ratio and durability.
Hot-dip galvanizing coats the steel in a layer of zinc, which acts as a sacrificial anode, preventing the underlying steel from oxidizing and corroding.
Yes, we specialize in customization. We can produce step gratings, special-shaped panels, and plug-in gratings according to your exact drawings or requirements.
They are widely used in city road drainage, airport runways, car parks, railway platforms, and industrial plant flooring for ventilation and drainage.
The I-Bar shape provides increased structural rigidity and higher load-bearing capacity while reducing the overall weight of the grating panel.
