Replacing wood with steel has the following characteristics

1. Safe, reliable, simple and efficient. Square steel keel is more rigid, stable and reliable than wooden keel; Square steel is used, with consistent section, simple and convenient construction and high efficiency.

2. There are many times of turnover, less amortization expenses, and significant comprehensive economic benefits. Square steel is used to replace timber, and low value consumables in the project are changed into turnover materials. Square steel keel can be reused in multiple project construction, and can be used for more than 300 times.

3. Light weight, small volume and convenient transportation. The square steel keel is small in volume and light in weight, and convenient for short distance and long distance transportation, which can be used for off-site project turnover.

4. It occupies a small construction site and has obvious advantages for projects with a small construction site.

5. The members are standardized and modularized, and the square steel pipes are uniform in specifications, simple and reliable, and fast in installation. It is not only applicable to the construction of shear wall structures, but also to the construction of frame columns, beams, and slabs.

6. While improving the construction quality, it ensures the cleanness of the construction site and lays a foundation for civilized construction.

7. It is not affected by environmental conditions and the construction period is guaranteed.

8. Energy conservation and environmental protection. Save wood and protect limited forest resources; Reduce the use of wood, reduce wood chips, and reduce air pollution; Save labor and improve work efficiency.

9. After the square steel replaces the wooden square as the secondary keel, the structural stress performance is good, and the phenomenon of private pulling and random sawing is avoided from the source.
