1. The vertical beams are cold rolled steel material, a square structure increases the force area, so that the material is not easy deformation, greatly increasing the number of reuses. (Reusable proper custody about 300 times) 2. vertical bar free expansion, which can meet the wall using different heights. 3. To improve the use of technology, greatly improve the progress of the project, but the wall is not easy to make the run mode, higher flatness. The steel timber to save a lot of wood, to achieve a high environmental benefits. 5. The beams are double pipe, this also increases the contact area, up to prevent mold. 6. The construction is simple, convenient, labor, material saving, time-saving and more security. 7. Our welding process uses carbon dioxide arc welding, greatly guarantee the quality of welding, to ensure safe use, but also increases the life of the product. 8. crossbar and primary steel pole used greatly to ensure product quality. 9, shear wall support system can withstand up three tons clamping force, do not run up the mold does not die, the better to ensure construction quality.
