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.
Heavy Structural Steel Components are large, thick-plate load-bearing members engineered for industrial buildings, infrastructure, equipment foundations and other high-load structures. ZSJH Steel fabricates heavy beams, columns, box sections, girders, brackets and welded assemblies according to customer drawings and approved fabrication documents.
Steel Truss Welding Service is a professional welding processing service for customer-supplied or customer-specified steel components. ZSJH performs welding of truss chords, webs, nodes and assembled truss members, with welding method, joint preparation and inspection arranged according to approved drawings and project requirements.
Epoxy Coating for Structural Steel provides epoxy intermediate or protective coating for industrial steel exposed to demanding environments. The service covers the agreed preparation, application, curing and inspection stages for fabricated structural steel supplied or specified by the customer.
Steel Plate Shot Blasting Service prepares flat carbon-steel plates and cut plate blanks for subsequent coating or approved surface treatment. The service removes specified contaminants and develops the surface profile required by the coating specification.
OEM(Original Equipment Manufacturer) Production Machinery Frames are machine frames and production-line bases manufactured with controlled geometry and equipment interfaces. ZSJH manufactures non-standard steel parts for OEM customers under customer-controlled drawings, specifications, samples and revision requirements.
Shop-Welded Steel Frame Subassemblies are factory-completed transportable frame sections for efficient site erection. The product is supplied as a completed structure or component, not as a standalone welding service. ZSJH combines primary and secondary frame members with welded shop joints and coordinated site interfaces and delivers the assembly ready for transport, installation or equipment integration.
Hot-Dip Galvanized Steel Beams and Columns are primary load-bearing beams and columns with galvanized surface protection. 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.
Gusset plates connect braces, truss members and frame components at engineered nodes. Finished plates can include bolt holes, slots, copes, bevels, weld tabs and identification marks for accurate field assembly.
Custom Box Steel Columns are closed rectangular or square members fabricated from steel plates. The closed section provides strong biaxial stiffness and torsional resistance for heavily loaded frames, wide interfaces and structures where column stability is important.
Built-Up Steel Beam Fabrication combines plates, rolled sections and reinforcement details into one engineered member. The flexible configuration supports heavy loads, long spans, transfer zones and complex interfaces while allowing material to be concentrated where it is structurally needed.
Heavy-Duty Industrial Equipment Frames are rigid welded structures that support large machines, production systems and process equipment under high static, dynamic or vibration loads. Each frame can be fabricated according to customer drawings, equipment interfaces and installation requirements.
