Our Custom Steel Fabrication service delivers tailor-made steel components and structural assemblies based on customer drawings, specifications, and project requirements. Our capabilities include CNC cutting, drilling, bending, welding, assembly, surface treatment, inspection, and export packaging. We can customize material grades, dimensions, plate thicknesses, connection details, and protective finishes for different applications. With precise production, strict quality control, and reliable delivery, our fabricated steel products are widely used in industrial buildings, warehouses, bridges, equipment platforms, machinery supports, energy projects, and other complex steel structures.
Custom Industrial Steel Support Frames provide project-specific structural support for production equipment, processing systems, machinery and industrial installations. Each frame is fabricated according to approved drawings, load requirements and equipment interface details.
Tubular Steel Structure Welding Service is a professional welding processing service for customer-supplied or customer-specified steel components. ZSJH performs welding for round tubes, square tubes, hollow sections and tubular structural nodes, with welding method, joint preparation and inspection arranged according to approved drawings and project requirements.
Industrial Anti-Corrosion Steel Painting provides multi-layer primer, intermediate coat and topcoat systems for industrial corrosion protection. The service covers the agreed preparation, application, curing and inspection stages for fabricated structural steel supplied or specified by the customer.
Pre-Paint Steel Surface Preparation prepares mixed fabricated steel parts selected according to the coating project for subsequent coating or approved surface treatment. The service removes specified contaminants and develops the surface profile required by the coating specification.
Batch-Produced OEM Steel Plate Parts are repeat plate parts manufactured by cutting, drilling, bending and secondary fabrication. ZSJH manufactures non-standard steel parts for OEM customers under customer-controlled drawings, specifications, samples and revision requirements.
Welded Industrial Skid Frames are completed welded base frames for equipment, process skids and industrial modules. The product is supplied as a completed structure or component, not as a standalone welding service. ZSJH combines base beams, cross members, mounting plates, equipment supports and lifting provisions coordinated to layouts and delivers the assembly ready for transport, installation or equipment integration.
Hot-Dip Galvanized Steel Stairs and Walkways are galvanized stairs, walkways and maintenance access systems for exposed industrial sites. Components are fabricated to approved drawings and prepared for galvanizing so exposed surfaces, internal cavities and connection details can receive the specified corrosion-protection treatment.
Custom Flange and Web Plates are finished plate components for welded H-beams, plate girders and other built-up members. They can be supplied with cut profiles, butt-joint preparation, holes, slots, camber references and piece marks for controlled downstream assembly.
Custom Tubular Steel Columns are hollow circular, square or rectangular members fabricated or supplied to project requirements. Their closed geometry offers efficient compression behavior, clean appearance and useful resistance to torsion and buckling when correctly designed and detailed.
Industrial Steel Crane Beams support overhead-crane rails and repeated wheel loads. Fabrication focuses on rail-seat accuracy, bearing stiffeners, splice alignment and connection interfaces so the finished runway members can be installed and aligned efficiently.
Heavy Long-Span Steel Trusses are engineered load-bearing systems for wide column-free spaces and major roof structures. ZSJH Steel fabricates tubular, plate-built and box-section trusses according to customer drawings, approved connection details and project delivery requirements.
