Stainless Steel ERW Pipes(SS ERW pipe) are produced from stainless steel raw materials using the Electric Resistance Welding (ERW) process.

Steel pipe piles are products made of steel pipes, tongues and grooves, and tenon pins.

Compared with welded steel pipes, cold-drawn seamless pipes are a type of steel processed through a series of cold drawing, cold bending and other technologies in a normal temperature environment.

During the construction of high-speed railway bridges, steel pipe piles are the main part of the bridge support system, and their construction technology has a direct impact on the bridge's support capacity.

The choice between Electric Resistance Welded (ERW) and Spiral Welded pipes depends on various factors, including project requirements, environmental conditions, and budget constraints.

Sheet pile soilless beton is a foundation construction technology used in projects such as roads, railways and dams. It uses steel sheet piles as the bearing body and is embedded in the ground to form a stable structure to support and distribute the load.
