1).good anti-skipping, used in wet , slipping area, especially the sea oil platform
2).Hot-dipped galvanized,high anti-corrosion, 30years life time, can be used as channel cover with frame, anti-thief, safe and easy to open
3).High strength, and better than cast iron, can be used in wharf, airport and other long span and heavy loading environment.
4).Large hole for drainage, Water leakage area up to 83.3%, it is the best choice of forestair.
5).Good-looking : clean lines, silver appearance, modern idea, save material , save cost; when long span, heavy load, it is cheaper than cast iron.
