HAISHENG supplies high-quality Cold Rolled C Section Steel Purlins, we are a professional manufacturer and supplier of steel structural components. These C-section purlins are formed through the continuous cold-roll forming of hot-rolled steel strips using fully automated machinery. They feature a standard C-shaped cross-section and are classified as lightweight, thin-walled structural profiles. Produced without the need for hot processing, they offer precise dimensions and an optimized cross-sectional shape. They are widely used as load-bearing and structural support components—such as wall purlins, roof purlins, brackets, columns, and secondary beams—in steel-structured buildings.

As a reliable manufacturer and one-stop supplier of steel structures in China, HAISHENG provides Steel Roof Gutter System for Buildings. These are trough-like drainage components installed between roof spans, at the junctions of high and low roof sections, or along parapet walls. They serve as core elements of organized drainage systems, collecting rainwater from the roof and channeling it into downpipes for discharge, thereby preventing uncontrolled runoff from eroding walls and foundations.

Choose HAISHENG—a China-based, one-stop supplier of prefabricated steel wall cladding panels. We offer three core procurement services: custom cutting, complete system customization, and full-container direct shipping. Our panels feature a range of Al-Zn (Aluminium-Zinc) substrates and paint finishes, making them suitable for exterior wall cladding in inland, riverside, coastal, and chemical plant environments.

As a specialized manufacturer and one-stop supplier of steel structures in China, HAISHENG offers direct shipment of corrugated steel roofing panels for structural buildings. Roll-formed from Al-Zn (Aluminium-Zinc) coated steel substrates, these panels integrate waterproofing, thermal insulation, and wind-resistant enclosure functions. Available in a wide range of profiles and easy to install, they are widely used in steel-structured factories, as well as large-span space frame and reticulated shell roofing projects.

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.
