Application:
Steel grating has been widely used in all walks of life both at home and abroad, mainly used for industrial platform, staircase pedal, banister, channel floor ,railway bridge service, high tower platform, the drain cover, manhole covers, road barrier ,three-dimensional parking lot, organs, schools, factories, enterprises and institutions, the stadium fence, garden villa, also can be used as a residence outside the window, balcony guardrail, highway ,rail barrier ,etc.
Surface: there are three types:hot-dipped galvanized ,electro-galvanized and spraying brushing and soaking.anti-acid and alkali corrosion capacity the range PH6 to PH12.5,a stable protective film will be formed on the zinc surface.it has good anti-corrosive property.
Packing: normally packed in pilling up ways with two pieces of square wood on both upperand bottom sides. there are four or six pieces of M10 long bolt penetrading the gratings and screwing together. it is suitable for loading and unloading by fork-lift and crane.
