The steel and wood keel is made of hot-dip galvanized square (rectangular) steel pipes or black pipes, which is a new product that replaces the traditional template to support the wooden keel (wooden square). It is also an upgraded replacement product for the (C-shaped steel+wooden square) steel and wood keel. This product belongs to the category of energy-saving and environmentally friendly products. In practical engineering applications, it can save 90% of wood, with a turnover rate of more than 40 times that of wooden keel. It is easy to store, transport, and construct, with strong universality. It has obvious economic and social benefits, and is a new product recommended by the Housing Wood Conservation and Development Center. The sales price of this product is only three times the price of wooden keel (wooden square), and the number of uses is 40 times that of wooden square.

Characteristics of steel and wood keel:

1. Safe, reliable, and simple. Square steel keel has better rigidity and stability than wooden square keel

Definitely reliable; The use of square steel ensures consistent cross-section, making construction simpler, more convenient, and more efficient.

2. With multiple turnover usage times and low amortization costs, it is an example of steel and wood keel engineering with significant comprehensive economic benefits. Steel and wood keels can be reused in multiple construction projects, with a turnover of over 300 times and low amortization costs.

3. Lightweight, compact, and easy to transport. The square steel keel has small size, light weight, and is convenient for long-distance transportation, making it suitable for long-distance engineering turnover.

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

5 components are standardized and modular, with simple attachments and strong applicability. The square steel specifications are uniformly connected with fixed accessories, which is simple and reliable, and the installation speed is fast. Not only suitable for shear wall construction, steel and wood keels are suitable for frame column, beam, and plate construction.

Due to the influence of unfamiliar environmental conditions, steel and wood keels replace wooden blocks, and the construction period is limited. The square steel back ridge is lightweight and easy to handle. It is completely manually disassembled and not affected by weather changes, and does not need to rely on large mechanical equipment to shorten the construction period.

7. Energy conservation and environmental protection. Save wood, steel and wood keel, and protect forest resources; Save steel and protect mineral resources; Saving plastic, promoting public health; No need to cut square wood, no wood chips, reducing atmospheric pollution; Save labor and improve work efficiency; Square steel can be recycled, and waste can be recycled.

The q235 square tube used in the production process of steel and wood keel is a long steel strip with a hollow cross-section and no seams around it. Steel pipes have a hollow cross-section, high flexural and torsional strength, and a relatively light weight. They are an economic cross-section steel that can improve material utilization, simplify manufacturing processes, save materials and processing time. Square pipes have high flexural strength, and some agricultural machinery skeletons and construction formwork support steel and wood keels are commonly used.
