The steel back ridge is composed of the main back ridge and the secondary back ridge. The main back ridge is also called the main keel, which is used horizontally and horizontally in the formwork support, and the secondary back ridge is also called the secondary keel, which is used vertically and vertically in the formwork support. The structure includes small C shape, small square steel, small figure, steel clad wood, etc.

Introduce the advantages of steel backing in use. 1. Good molding effect. The new steel support system has high strength and stability, and the solid reinforcement system can eliminate the rising die, slurry leakage and structural deformation.

2. Low cost. The turnover times of the new steel support system can reach more than 300 times, the single use cost is low, and the residual rate is high. 3. It is conducive to safe and civilized construction. The new steel support system is used for construction. After demoulding, the site is free of garbage, rust, fire hazard, residual wood pins of chain saws and other construction garbage. The construction site is clean and meets the green building construction standards. 4. Simple technology and operation. The new steel support system is easy to install, operate and learn. The installation requires only simple training, and anyone can install it. 5. High construction efficiency and short construction period. Compared with the traditional formwork steel support system, the new formwork steel support system has high construction efficiency, can greatly shorten the construction period, save management costs for departments, and can also shorten the development cycle of real estate developers. 6. Wide application range. The steel support system is applicable to all shear wall structures, frame shear structures, frame structures and wall columns.
