Steel sheet piles can be divided into cold-formed steel sheet piles and hot-rolled steel sheet piles.
The more common steel sheet pile is called Larson steel sheet pile.Hot-rolled steel sheet piles are made of hot-rolled steel plates through shearing, flanging, rolling and other processes. Its cross-sectional shape is Z-shaped or U-shaped, which can effectively absorb and disperse external forces and improve the bending and shear resistance of the pile.
Cold-formed steel sheet piles are continuously rolled and formed by a cold-forming unit, and the side locks can be continuously overlapped to form a steel structure with a sheet pile wall. Cold-formed steel sheet piles are made of thin plates (common thickness is 8mm ~ 14mm) and processed by cold-forming forming units. Its production cost is lower, the price is cheaper, and the fixed-length control is more flexible.
Cold-formed steel sheet piles are made of thinner sheets and processed by cold-forming forming units. Its production cost is lower, the price is cheaper, and the fixed-length control is more flexible. However, due to the crude processing method, the thickness of each part of the pile body is the same, and the cross-sectional size cannot be optimized, resulting in an increase in the amount of steel used; the shape of the locking part is difficult to control, the joints are not fastened tightly, and water cannot be stopped; due to the capacity constraints of the cold bending processing equipment, only It can produce products with low steel strength and thin thickness; and the stress generated during the cold bending process is large, and the pile body is prone to tearing during use, so its application has great limitations. In engineering construction, the application range of cold-formed steel sheet piles is relatively narrow, and most of them are only used as supplementary materials.
Features of cold-formed steel sheet piles: According to the actual conditions of the project, the most economical and reasonable cross-section can be selected to optimize the engineering design. It saves 10-15% of materials compared with hot-rolled steel sheet piles of the same performance, greatly reducing construction costs.
Advantages of U-shaped cold-formed steel sheet piles
1. The large cross-section width ensures that the mechanical properties of the cross-section are fully utilized.
2. The structure is symmetrical and easy to reuse.
3. The product’s cross-sectional structure is reasonably designed and has a high “quality coefficient”
4. The use of steel sheet piles is not restricted by weather conditions;
5. The construction has significant environmental protection effects, greatly reducing the amount of soil taken and the amount of concrete used, effectively protecting land resources;
6. Green and environmentally friendly.
Advantages of Z-shaped cold-formed steel sheet piles
1. The cross-section width is large and the pile sinking effect is remarkable.
2. Large section modulus.
3. The moment of inertia is higher, which enhances the stiffness of the steel sheet pile wall and reduces structural deformation.
4. Excellent anti-corrosion effect.
5. The construction is simple and the construction period is shortened.
6. The use of steel sheet pile materials can simplify the complexity of inspection materials and system materials.
Over the years, through the research, development, production and practice of cold-formed steel sheet pile products, the following characteristics of the WR series cold-formed steel sheet piles have been formed:
1. The cold-formed steel sheet piles produced are relatively complete in variety.
2. Product specifications form a series
3. The product’s cross-sectional structure is reasonably designed and has a high “quality coefficient”
4. Can provide cold-formed steel sheet pile products in a variety of steel grade materials
5. Implement strict quality standards
6. Products with special specifications can be provided.
