The carbon content of cold heading steel is generally controlled by the middle and lower limits. The silicon content in the steel exceeds 0.10%. As the silicon content increases, the tensile strength and hardness of the steel increase, but the elongation is low, and the reduction of the area shrinkage is more significant, which is not conducive to cold deformation. The medium manganese content in steel can improve the existence and distribution of sulfur in steel, which is beneficial to improve the cold formability of steel.
Steel Plastic Composite Geogrid : Ultimate tensile Strengths from 20kN/m to 600kN/m . Range: Steel Plastic composite fake top network used underground in the coal mine .
1. It reinforce old asphalt concrete road surface and asphalt layer, and prevents damage ;
2. It is used for rebuilding cement concrete road surface into composite road surface and restraining reflection caused by block contraction .
3. It is used in road expansion and improvment project and crack caused by old and new combination position and uneven sedimentation ;
4. It is used in soft soil base reinforcement treatment , is favorable for soft soil water separation and concretion,restrains sedimentation effectivly,distributes stress uniformly and improve overall strength of road base;
5. It is sued for preventing contraction crack caused by new road semi-rigid base layer,and reinforces and prevents road surface crack caused by foundation crack reflection.
