Product Description 

Heavy duty steel gratings are also called heavy duty steel gratings. Heavy duty steel gratings are made of

a certain size of carbon flat steel, stainless steel, brass plates, aluminum plates through slots (holes),

plug-in locks, welding, finishing and other processes.

Made. The pressure lock grille plate culverts the characteristics of high-strength, anti-corrosion and

maintenance-free of the pressure-welded steel grid plate, and it has the unique combination of precision,

light and beautiful structure, natural harmony and elegant style.
Heavy duty steel gratings are widely used in civil engineering and commercial buildings, theaters, subways,

urban railways and other municipal engineering fields. They can be used in airport, highways, industrial

platforms, port terminals and other site platforms with special requirements.
