Marine steel grating is a product specially tailored for the shipbuilding industry. Due to the harsh working environment of the ship, the hull is subject to chemical corrosion, electrochemical corrosion of seawater, and corrosion of marine organisms and microorganisms. There are strict requirements for the selection of materials, processing technology, welding technology, edge-wrapped flat steel and twisted rod specifications, welding of fixed plates, and thickness of hot-dip galvanized zinc layer for marine steel grating. The products are used in various occasions such as furnace chamber passages, deck passages, cargo storage platforms, chimney platforms, and wheelhouse platforms.
