Fixed steel grating welding and mounting clip in two ways. Without dismantling of permanent, can be welded, welded on its supports. Specific location, at each corner of the first root of flat steel plate, the weld length is not less than 20 mm, a height of not less than 3 mm fillet welds. Has the advantage of using the mounting clip without damaging the zinc layer and easy removal of each plate should be used at least four mounting clips for larger plate on the best support available to install a few things more. Steel grating is widely used in power plants, construction, municipal engineering, transportation, multi-channel shelf, offshore engineering, plant wind truss channel chemical tank platform, parking, light industry, oil chemical, petrochemical, agriculture, refined oil refineries, sewage treatment, mining and refining, pulp and paper, gas tank maintenance platform and runs, industrial machinery, garden, textile chemicals, iron and steel industry, port engineering, steel cable through the gallery, waste disposal and disposal of chemical fertilizer industry, pesticide plant equipment maintenance platform, airport projects.
