High-Performance Structural Steel Components for Durable Construction

HAISHENG is a specialized manufacturer and supplier of non-standard steel structural columns, offering profiles with unique cross-sections such as cruciform, L-shaped, and Y-shaped designs. Leveraging national standard base materials and advanced simulation analysis, these columns balance structural load-bearing requirements with efficient interior space utilization, making them suitable for residential, commercial complex, and cultural-tourism landmark projects.

As a specialized manufacturer and one-stop supplier based in China, HAISHENG offers custom, volume-produced Circular Tube Steel Structure Columns. Leveraging advanced anti-corrosion processes and a streamlined structural design, these columns are ideal for high-humidity, windy coastal environments. They balance structural load-bearing capacity with architectural aesthetics and support factory prefabrication, export-grade packaging, and comprehensive procurement services.

As an established Chinese manufacturer and supplier specializing in the steel structure sector, HAISHENG produces and distributes square steel tube structural columns. Crafted from Q235 and Q355 grade steel, these columns feature a closed-section design for balanced load-bearing and a sleek, minimalist aesthetic. With the advantage of readily available stock for rapid delivery, they are suitable for diverse applications including industrial facilities, curtain walls, and light-gauge steel buildings.

HAISHENG is a leading domestic manufacturer of high-quality steel structures, specializing in the on-demand customization and modular prefabrication of Long Span Steel Lattice Shell Structures. These structures are ideal for applications such as coal storage sheds, stadiums, and large-span curved roofs (including glazed domes). Leveraging the structural principles of arch-shell mechanics to optimize steel usage, the system includes comprehensive support and envelope components designed to withstand rigorous conditions, including high wind and snow loads and seismic activity.

HAISHENG is a professional manufacturer and one-stop supplier of steel structures in China. Our Large Span Steel Space Frame Structures—available from stock—are integral load-bearing systems assembled from multiple steel members arranged in a specific grid pattern and connected via welding or bolted spherical joints. Functioning as spatial trusses, they distribute loads uniformly across the entire structure. Characterized by long spans and high structural integrity, they are widely used for the roof and ceiling load-bearing systems of column-free, open-plan buildings.

HAISHENG is a professional manufacturer and supplier of steel knee bracing support members in China. Knee braces are specialized lateral support components for steel structure roofing; typically made of angle steel, they connect the roof purlin diagonally to the bottom flange of the steel beam. They act as tension-compression struts to effectively restrain the lateral displacement of purlins, preventing buckling or lateral bending deformation under compression, while simultaneously enhancing the overall lateral rigidity of the roof system. They are essential small-scale reinforcement components for light steel industrial building roofs.
