Reducing wind resistance: Due to good ventilation, wind resistance is small in case of strong wind, reducing wind damage.
Simple design: no need for small beams, simple structure, simplified design; no need to design detailed drawings of steel gratings, just indicating the model number, and the factory can design the layout drawing on behalf of the customer.
Good ventilation, lighting, heat dissipation, explosion-proof and anti-skid performance;
Acid-base corrosion ability: in the range of PH 6 to PH 12.5, a stable protective film is formed on the surface of the stainless steel manhole cover, with good corrosion resistance.
