HAISHENG specializes in providing Prefabricated Non-Poured Steel Floor Deck Panels. As a Chinese manufacturer and one-stop supplier of steel structures, we distinguish our products from conventional open-profile, closed-profile, and rebar-truss composite decks (which require cast-in-place concrete). Our steel floor decks fall into two main categories—all-steel hollow-core and steel-sandwich composite—utilizing built-in stiffeners for independent load-bearing capacity and requiring absolutely no wet concrete work. These panels offer targeted solutions to industry challenges such as insufficient load-bearing capacity in existing beams and columns, inability to pour concrete during winter or rainy seasons, dust pollution affecting the neighborhood, and the inability to recycle materials during future demolition.

HAISHENG is a specialized manufacturer and supplier of Closed Steel Floor Decking Panels for Buildings. These panels are produced via cold-roll forming using high-zinc hot-dip galvanized steel strips as the base material. Featuring a fully enclosed interlocking cross-section and integrated shear-resistant ribs, they are installed over primary and secondary steel beams. They bond with cast-in-place concrete to form an integrated composite floor slab, serving multiple functions—permanent formwork, primary tensile reinforcement, and fire/sound insulation—making them a premium choice for load-bearing floors in high-rise steel structures.

As a one-stop steel structure supplier, HAISHENG offers direct shipment of in-stock Open Steel Decking Panels for Floors, featuring on-demand cutting, complete accessory kits, and compliance with national standards for material inspection. We handle bulk custom orders; our entire product range meets current national steel structure specifications and is suitable for various industrial and civil steel-concrete composite flooring projects.

HAISHENG is a professional manufacturer and supplier of square hollow steel tube purlins. These load-bearing structural components are fabricated from square seamless or welded rectangular steel tubes through processes such as straightening, cutting to length, punching, and anti-corrosion treatment. Featuring a standard square cross-section, they offer balanced load distribution across all four sides, high rigidity, and superior stability. They are widely used in light steel building roofs, walls, and load-bearing frameworks that require high load-bearing capacity, handle complex stress conditions, or feature regular geometric designs.

As a direct manufacturer, HAISHENG Steel Structure offers immediate stock of Hot Rolled Steel Channel Purlins for Roofing, with support for custom hole punching, accessory fabrication, and specialized anti-corrosion or color-coating treatments. Compliant with the GB/T707 national standard and manufactured from Q235B hot-rolled steel, our products feature anti-corrosion options including painting and hot-dip galvanizing. They are specifically designed to meet procurement needs for heavy-load roofing, the renovation of aging industrial facilities, and purlin replacement in high-temperature workshops.

Are you looking for a professional and reliable manufacturer of Cold Rolled Z Section Steel Purlins? HAISHENG supports bulk wholesale, custom specifications, and bundled shipping with matching accessories. Our profiles are cold-formed from Q235B hot-dip galvanized steel strip, making them suitable for various steep-slope, long-span steel structure roofs. We offer two tiers of anti-corrosion galvanizing standards tailored for inland and coastal environments. With our own in-house cold-forming production lines, we can simultaneously supply a complete set of installation accessories, including sag rods, flange braces, and purlin cleats.
