Steel pipes are an indispensable component in construction, energy transmission, mechanical engineering, and infrastructure development. Among the many widely used materials, carbon steel pipes and low-carbon steel pipes stand out due to their balance of performance, usability, and cost-effectiveness.

Carbon steel and mild steel are two of the most widely used materials. While mild steel is technically a type of carbon steel, the differences in carbon content result in noticeable variations in strength, hardness, weldability, and application scope.

ERW welded pipe (Electric Resistance Welded pipe) is a type of welded steel pipe produced by forming steel coils into a cylindrical shape and welding the edges together using high-frequency electrical resistance.

CHWS stands for Chilled Water Supply. CHWS piping refers to the piping that transports chilled water produced by chiller units to cooling equipment, such as air handling units (AHUs), fan coil units (FCUs), heat exchangers, and cooling coils.

U-type steel sheet piles offer flexibility and ease of use for general applications, while Z-type profiles deliver maximum bending resistance and structural efficiency for demanding projects. Flat and special profiles further expand the range of engineering solutions available.

SCH 10 is suitable for low-pressure applications, SCH 40 serves as the industry standard for most pressure pipelines, and SCH 80 provides the highest pressure resistance for demanding operating conditions.

SCH 10 steel pipe is a common type of thin-walled steel pipe. For many projects, SCH 10 steel pipe is frequently used in stainless steel and some low-pressure carbon steel piping systems due to its thin wall thickness, light weight, and relatively controllable cost.

ASTM A36 steel is one of the most widely used carbon structural steels in the global market. Thanks to its balanced mechanical properties, good weldability, and cost-effectiveness, A36 steel is commonly specified in construction, fabrication, and general engineering projects.

ASTM A36 steel plate is one of the most widely used carbon structural steel plates in the global market. Thanks to its stable mechanical properties, good weldability, and cost-effectiveness, A36 steel plate is commonly specified in construction, fabrication, and general engineering projects.

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.
