Hot Dipped Galvanized Grating ( simplified as HDG Grating) is a versatile bar grating flooring material made of quality carbon steel in accordance with Chinese standard, American Standard, Australia or British Standard. The hot dipped galvanizing for the steel plate surface is processed according to standard: China GB/T13912-92 / ASTM (A123) / BS729. The thick zinc coating gives more protection and enables the grating floors excellent corrosion resistance for on-shore and off-shore elements. Hot dipped galvanized grating has bright metal aesthetic appearance and a light structure easy for loading and installation.
Features
Good anti-corrosion capacity;
Shiny surface appearance;
Ventilation;
Heat, explosion-proof;
Others.
Qindelin hot dipped galvanized steel grating meets the following standards:
Steel material we use meets the Standard of China GB700-88 / ASTM (A36) / BS4306 (43A).
HDG Grating production meets one of the following:
China YB/T4001-1998
America ANSI/NAAMM (MBG531-88)
Britain BS4592-1987
Australia AS1657-1992
Applications
Hot dipped galvanized grating with excellent corrosion resistance makes good choice for outdoor off shore industrial gangway flooring panels and ladders. Common sizes for hot dipped safety grate is 30 × 3mm thick load bearing bars with a pitch of 30mm and traverse bars at 50mm or 100mm.
