With the increasing use of hook mesh, the method of bridge rail is also different. The height of the outer railing of the walkway or seat belt should not be lower than 1.10 meters. The net distance between railings should not be greater than 140 mm and horizontal bar rails should not be used. The planning of the hook mesh is necessary to be safe and reliable, the bolt should be installed on the basis of the railing, its strength should meet the requirements of the standard.

Some welding methods of galvanized steel mesh will reduce the quality of low carbon steel welded joints, such as electroslag welding. Because the line energy is high, the coarse grains in the heat affected zone of welding will become very coarse, leading to a severe reduction in impact toughness. After welding, it is necessary to normalize with refined grains to improve impact toughness.

2. Start running water. Make sure the water is warm so the cat won’t put up a fight.

4, the material requirements of silk: wire drawing weaving, electric galvanized wire weaving, hot galvanized wire weaving, first woven after hot plating.
