Steel pipe piles and steel sheet piles are two widely used steel solutions, but they serve very different purposes on construction sites. Understanding their differences in construction applications helps you select the most suitable system for specific project requirements.

Steel pipe piles are widely used in modern construction projects, especially in situations requiring high reliability and deep foundation pits. With urban development and the increasing size and weight of buildings, traditional shallow foundation pits are insufficient to meet the requirements of bearing capacity and stability.

Sheet piles are widely used in modern construction engineering for retaining walls, foundation pit support, and complex hydraulic systems. Sheet piles interlock to form a continuous, impermeable wall, effectively preventing ground subsidence and soil erosion.

Larssen Sheet Piles (LSP) originated in Germany and are a classic type of sheet pile named after their inventor, Friedrich Larssen. It is not a single product model, but rather a high-performance sheet pile system produced using a hot-rolled process, featuring a unique U-shaped corrugated cross-section and a precision interlocking structure.

ASTM A36 round bar is a low carbon structural steel round bar produced based on ASTM A36/A36M standards with excellent weldability, good processability and moderate strength.

When selecting carbon steel plates for structural or pressure-bearing applications, two standards often come into play: ASTM A36 and ASME SA36. Although they appear very similar and are sometimes even interchangeable, they differ significantly in regulatory bodies, application scope, testing requirements, and certification standards.

ASTM A36 is one of the most widely used international standards for low-carbon structural steel. Developed by ASTM International, this standard specifies the types of steel, plates, and reinforcing bars used in general structural engineering.

Hot-rolled steel is the backbone of modern infrastructure—powering everything from skyscrapers and bridges to heavy machinery and pipelines. Unlike cold-rolled steel, which is processed further for surface finish, hot-rolled steel is prized for its cost-effectiveness, weldability, and mechanical properties.

Hot-rolled steel bars are bars produced by rolling under high-temperature conditions. Common cross-sections include round bars, square bars, flat bars, and hexagonal bars.

Common Defects and Prevention of Hot-Rolled Steel Pipes Hot-rolled steel pipes are critical to modern engineering—from high-pressure energy transmission and petrochemical piping to construction, machinery, and boilers.

In the industrial piping field, choosing between resistance welded steel pipes and seamless steel pipes is one of the most common decisions customers face. Pipe selection requires not only focusing on quality but also balancing structural integrity and project economy.

In the global steel pipe market, ERW steel pipe(Electrical Resistance Welded steel pipe) is the most cost-effective and widely used solution in the construction, infrastructure, and energy transmission sectors.

Seamless steel pipe is a type of steel pipe without any welded joints. It possesses excellent mechanical strength and a seamless, integrated structural characteristic.

The Schedule 40 pipe elbow is one of the most widely used pipe fittings in piping, industrial piping, and fluid transport systems. It features balanced wall thickness, reliable pressure resistance, and broad material compatibility, playing a crucial role in changing the direction of fluid flow while maintaining system integrity.

Steel pipes of different wall thickness grades (SCH) are widely used in various piping systems, with SCH 40 and SCH 80 being two of the most common choices. Both conform to ASME/ANSI B36.10 standards, but their wall thickness and load-bearing capacity differ significantly.
