Hot-rolled steel is one of the most important intermediate or terminal products in the steel production process. It mainly refers to heating the steel billet above the recrystallization temperature and rolling it into various shapes through a rolling mill.

Hot-rolled steel sheet piles are high-strength steel section products made through high-temperature rolling processes. Their cross-sectional shapes include U-shaped, Z-shaped and straight web types. They are mainly used in water conservancy projects, foundation pit support, bridge cofferdams and rail transit construction. They feature strong bending resistance, high construction efficiency and reusability.

The anti-corrosion protection of pipelines is a key link to ensure the long-term safe operation of the entire system. At the joints of pipelines, due to welding or connection operations, the original anti-corrosion coating may be damaged. Therefore, re-coating or re-coating must be carried out. This process is called field joint coating.

In HVAC and industrial cooling systems, the chilled water system is an important component for achieving efficient energy transmission. To ensure the stable operation of the system, choosing the appropriate pipe material is of vital importance.

DH36 and AH36 Marine steel plates are two extremely important high-strength ship plate materials. Both DH36 and AH36 belong to high-strength hull structural steel and comply with the standards of the Classification Society Association.

Marine steel plate is one of the core materials in the fields of shipbuilding and Marine engineering. It needs to have high strength and excellent welding performance, and also be able to resist the erosion of seawater and various harsh environments.

Cement mortar lining (CML) is a protective technology in which cement mortar is sprayed or centrifugally poured on the inner wall of steel pipes or ductile iron pipes.

Hot-rolled steel plates possess outstanding performance, precision and surface quality. They are one of the most widely used steels in modern industry and are extensively applied in fields such as building structures, mechanical manufacturing, Bridges, shipbuilding and pressure vessels.

Pile pipes are key materials for ensuring the stability of the foundation and the safety of the structure. Whether it is a bridge, port terminal or high-rise building project, choosing a reliable pile pipe supplier can directly affect the quality, schedule and cost of the project.

SSAW pipe piles are large-diameter steel pipes made by spirally welding hot-rolled steel strips, and are widely used in bridge foundations, port terminals, offshore platforms and deep foundation pit support and other projects.

Hot-rolled steel plates are widely used in construction, shipbuilding, pressure vessels, Bridges and heavy machinery, etc. The surface quality directly affects the performance, appearance and market value of the products.

Steel pipe piles are widely used in foundation and Marine engineering, and different production methods affect performance and cost. When choosing piling pipes for foundation projects, should you choose ERW or LSAW?

Piling pipe is a kind of hollow steel pipe structure, which is usually used for bearing of foundation and supporting engineering. It can be used either as a steel pipe pile (directly as a bearing pile) or as a casing/casing (for drilling, pouring and temporary support).

ERW pipes are steel pipes that melt the edges of steel strips through resistance heating and then apply pressure to form weld seams. EFW pipes are made by melting the base material and filler metal through high temperatures generated by electric arcs or electron beams and then welding them together, which belongs to fusion welding.

Seamless rectangular tubes are steel pipes with a rectangular cross-sectional area, manufactured through a seamless process and without weld seams. It is usually made of high-quality carbon steel, alloy steel and stainless steel, featuring excellent strength, precision and corrosion resistance.
