As a reliable manufacturer and one-stop supplier of steel structures in China, HAISHENG offers readily available standard steel connection bolts for construction. Manufactured from ordinary carbon steel without high-strength quenching and tempering, these bolts transfer loads through the tension and shear resistance of the bolt shank itself. They serve as general-purpose fasteners primarily used for secondary joints, temporary fixation, simple splicing, and non-load-bearing connections in steel structures.

HAISHENG is a professional and reliable manufacturer of steel structures and a one-stop supply provider. It offers spot-on and bulk supply of High Strength Bolts for Structural Steel Connections (large hexagon high-strength bolts). It supports customization of specifications, bulk purchasing, and engineering supply. It is suitable for the construction of various main and secondary load-bearing nodes of steel structures and complies with national construction acceptance standards.

HAISHENG is a reliable China structural steel Manufacturer and one-stop Supplier, supplying Torque Shear High Strength Structural Bolts in stock. The full standard name is Torque Shear High Strength Bolt Assemblies for Steel Structures, complying with GB/T 3632. Each complete set consists of 1 bolt with round head and tail spline, 1 nut and 1 washer only fitted on the nut side. A thin shear neck (twist-off groove) is set between the spline tail and bolt shank as a pre-set weak section. When fully tightened by a special electric wrench, the thin neck will be cut off, which means the required pre-tension force is achieved. The spline tail at the bolt end will be automatically twisted off once the pre-set pre-tension force is reached, providing a direct visual signal to confirm full tightening.

HAISHENG, a one-stop manufacturer of steel structures, offers ready-to-ship embedded steel base plates for structural installation. These products support customization for irregular hole patterns, hot-dip galvanizing for corrosion protection, and selectable anchor bar specifications. Designed for embedded anchoring at steel-concrete junctions—such as those for crane beams, curtain walls, and equipment supports—they effectively resolve issues associated with post-installed anchors, such as loosening and structural damage.

As a reliable manufacturer and one-stop supplier of steel structures in China, HAISHENG offers readily available Heavy Duty Anchor Bolts for Steel Structures. These specialized fasteners—embedded into concrete foundations—consist of a threaded rod, a hex nut, a flat washer, and a spring washer. They are primarily used to securely anchor structural components such as steel columns, equipment bases, and factory steel pillars to the foundation, serving to support loads, ensure precise positioning, resist pull-out and shear forces, and stabilize the overall structure.

As a direct manufacturer, HAISHENG offers immediate supply of Truss Supported Steel Floor Decking Panels, featuring customizable cut-to-length dimensions, a choice of bottom formwork types, and a complete set of anchoring accessories. These panels are designed for long-span, heavy-load cast-in-place floors; they feature an inherent two-way load-bearing structure that eliminates the need for extensive temporary shoring and comply with national acceptance standards for prefabricated construction.
