The height of the shield should not be less than two meters. The length of the shield should be the width of the journey and the extension 10 meters away. The vertical load of the handrail on the bridge is 1.2KM/m, and the horizontal external load is 2.5KM/m, both of which should be calculated separately. Galvanized hook mesh is attributed to a hook mesh, it is the selection of galvanized wire, hot dip galvanized wire as raw materials, woven through the hook mesh crimping truncated.

Hot dip galvanizing is in the hot melt zinc liquid dip plating, production speed, thick but uneven coating, the market allows the low thickness of 45 microns, up to 300 microns above. It is dark in color, consumes more zinc metal, forms infiltration layer with base metal, and has good corrosion resistance. Hot dip galvanizing can be maintained for decades in outdoor environment.

Wire mesh first welding after galvanized is through the end of welding and then cold this company to produce wire mesh wire mesh steel mesh construction mesh floor heating mesh galvanized or hot dip galvanized. First galvanized after welding is to change wire mesh, after the end of welding can see the solder joint; The two processes are different in price. The cost of plating after welding is low, the appearance is smooth, and the cost of plating after welding is high, and it is not easy to rust.

Large roll galvanized wire welding net is made of high quality galvanized wire welding net, wire through the current, after mutual melting, strong connection point, and the formation of metal mesh. In the use of galvanized iron wire to find the thickness and soft and hard to the size of flowers, weight and softness corresponding to the degree, too soft florets to use fine wire, and heavy flowers, flowers with thick stems to use thick wire.
