80KN100KN national standard high-strength steel wire mesh, steel wire geogrid manufacturer wholesale

Description :

　　High strength steel wire mesh is a new type of reinforced mesh made by first welding multiple single high-strength steel wires horizontally and vertically into square holes through resistance welding, and then coating the welded steel wires with plastic.

　　It has the characteristics of high bidirectional strength and high rigidity. It is an ideal material to replace composite welded geogrids and woven geogrids produced.

　　This is because the steel wire mesh is determined by the following factors:

　　1、 The strength of the steel wire grid joints (tensile, shear, tear, and torsion resistance) should be high, and the joint force transmission performance of the longitudinal and transverse ribs of the grid should be good. It can transmit the force received by the transverse ribs to the longitudinal ribs through the joints, and vice versa. Therefore, it is required that the joint must have good overall integrity, and the strength of the joint must be relatively close to the strength of the rib (without breaking at the joint during tensile testing), or the difference in strength between the two must be small in order to match, which is the most reasonable and economical. Otherwise, if the strength of the joint is much lower than that of the rib, it will not be able to safely exert the tensile strength of the high-strength rib, resulting in a structural consequence of "big horse pulling small car" waste.

　　2、 The total area of the grid bars and ribs of the steel wire grating should be as small as possible compared to its opening area to ensure a relatively large mechanical interlocking and interlocking effect. That is to say, the mesh should bite as much soil as possible in order to fully utilize its biting effect. But the mesh size should not be too large, otherwise the stiffness of the ribs will decrease, which will actually reduce the biting force.

　　3、 The bars and ribs of the grille should be perpendicular to each other for more effective load transmission. If the two are not perpendicular, it will reduce the transmission effect of the load and deteriorate the reinforcement effect. This is different from pseudo grids (such as woven or composite welded). The nodes of the pseudo grid are woven or composite welded, with poor overall integrity and poor longitudinal and transverse force transmission performance.
