As a reliable manufacturer and one-stop supplier of steel structures, HAISHENG offers immediate stock availability of galvanized steel tie rods for structural bracing. These tie rods are specialized components for steel structure facilities; made from round steel, they feature threaded ends and an overall galvanized anti-corrosion coating. Used in conjunction with nuts and sleeves within roof and wall bracing systems, they provide tension and stability, distribute lateral loads, and control structural deformation.

HAISHENG is a specialized manufacturer and supplier of Self Tapping Screws for Steel Cladding Systems. These fasteners are engineered for use in steel structure facilities—specifically for roofing, wall cladding, flashing, and corner trim—and utilize their own threading or drill-point structures to fasten metal sheets directly. They fall into two main categories: standard self-tapping screws and self-drilling self-tapping screws. Most feature anti-corrosive zinc plating, making them suitable for outdoor environments.

HAISHENG is a specialized manufacturer and one-stop supplier of steel structure fasteners, offering readily available Hot Dip Galvanized Bolts for Steel Structures. We support bulk purchasing, customization of non-standard specifications, and the supply of complete connection assemblies. Our products feature two anti-corrosion finishes—electro-galvanizing and hot-dip galvanizing—and span strength grades from 4.6 to 10.9, making them suitable for steel structures in coastal, outdoor, and chemically corrosive environments.

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.
