ZSJH
A steel building performs as a complete structural system only when every joint transfers loads safely and accurately. Our engineered steel connection solutions are designed for warehouses, workshops, industrial plants, commercial buildings, steel platforms, roof systems, and other prefabricated structures.
ZSJH Steel manufactures assembly-ready connection components for primary and secondary steel framing. Each part is produced from approved fabrication drawings and supplied with coordinated bolt holes, identification marks, compatible fasteners, and suitable corrosion protection.
Whether your project requires a simple shear connection, rigid moment joint, column splice, bracing node, or a fully customized connection assembly, we can provide an integrated solution from detailing and manufacturing to inspection and export delivery.
Manufactured for connecting primary beams, secondary beams, crane beams, floor beams, and roof beams. Available designs include fin plates, end plates, seated connections, angle cleats, flange plates, and welded brackets.
Designed for column extensions, segment assembly, foundation installation, and beam-to-column framing. Typical components include splice plates, base plates, stiffeners, anchor bolts, and erection plates.
Gusset plates, clevis connections, tension rods, turnbuckles, and bolted brackets can be supplied for roof bracing, wall bracing, and horizontal stability systems.
Customized welded or bolted nodes are available for roof trusses, pipe trusses, lattice structures, and hollow-section steel frames.
Connection accessories can be manufactured for purlins, girts, eave struts, sag rods, canopies, stair frames, handrails, and other secondary steel components.
Connection components are cut, drilled, welded, inspected, marked, and packed before shipment, reducing processing work at the construction site.
CNC drilling and controlled fabrication help maintain consistent bolt-hole spacing and improve alignment during installation.
Prefabricated bolted joints can minimize field welding, shorten installation time, and simplify quality control at the project site.
Plate dimensions, hole patterns, bolt specifications, steel grades, welding details, and surface treatments can be adjusted to suit each project.
Connection plates, bolts, nuts, washers, anchor bolts, stiffeners, brackets, and other accessories can be delivered as one coordinated package.
Components are classified, labeled, bundled, and packed according to the erection sequence to support easier unloading and installation.

Our technical team reviews member sizes, plate details, bolt arrangements, welding symbols, surface treatment, and installation requirements.
Materials are checked against the approved bill of materials before cutting and fabrication.
Plates and sections are cut, drilled, punched, or formed using controlled equipment.
Components are positioned using fixtures and assembled according to approved fabrication drawings.
Hole spacing, plate dimensions, angles, weld locations, and assembly tolerances are inspected.
Components receive the specified surface preparation, painting, powder coating, or galvanizing.
Finished parts are checked for quantity, dimensions, appearance, identification marks, and packaging requirements.
Small components are packed in cases or on pallets, while larger assemblies are bundled and protected for container transportation.
Please provide structural drawings, connection drawings, material specifications, quantities, bolt requirements, surface treatment, and delivery destination.
Yes. We can supply connection plates, brackets, gussets, bolts, anchor assemblies, and welded nodes separately or as part of a complete steel structure package.
We can review the submitted details and provide fabrication suggestions related to plate processing, welding access, bolt installation, transportation, and assembly efficiency.
They can be included according to the project scope. We can supply bolts, nuts, washers, anchor bolts, tension rods, turnbuckles, and related hardware.
Yes. Each component can be marked with an erection number corresponding to the fabrication drawings and packing list.
Trial assembly can be arranged for complex nodes or critical connection systems when specified in the project requirements.
