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 Steel Frames for Industrial Buildings provide project-specific structural support for factories, warehouses, workshops and manufacturing facilities. Frame geometry, member sections, connections and protective coatings can be manufactured according to approved engineering drawings.
Box Section Steel Welding Service is a professional welding processing service for customer-supplied or customer-specified steel components. ZSJH performs welding for box sections, welded box columns, box girders and closed built-up members, with welding method, joint preparation and inspection arranged according to approved drawings and project requirements.
Polyurethane Topcoat for Steel Structures provides durable polyurethane finish coating for color retention, weathering resistance and appearance. The service covers the agreed preparation, application, curing and inspection stages for fabricated structural steel supplied or specified by the customer.
Heavy Structural Steel Shot Blasting prepares heavy built-up members, thick plate girders, box sections and oversized steel components 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 Manufacture) Fabricated Steel Brackets are custom brackets, supports and mounting components produced for customer products and assemblies. ZSJH manufactures non-standard steel parts for OEM customers under customer-controlled drawings, specifications, samples and revision requirements.
Welded Lattice Steel Structures are completed open-web structures assembled from chords, diagonals and nodes. The product is supplied as a completed structure or component, not as a standalone welding service. ZSJH combines chords, diagonal members, transverse members, gussets and end connections assembled as finished sections and delivers the assembly ready for transport, installation or equipment integration.
Hot-Dip Galvanized Steel Platforms are galvanized access and equipment platforms for wet or outdoor operating environments. 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.
CNC Thick Steel Plate Cutting provides programmed cutting for heavy-gauge steel plate used in structural and industrial components, with method and heat control matched to requirements.
Custom Steel Stiffener Plates reinforce webs, flanges, beam ends and column joints where local buckling or concentrated forces require additional capacity. Plates are supplied as finished, cut and prepared parts or welded subassemblies.
Custom Lattice Steel Columns are built-up compression members made from two or more longitudinal chords connected by lacing bars, battens or diaphragms. This open arrangement can deliver high radius of gyration and efficient load capacity for tall or widely spaced supports.
Custom Steel Box Girders are closed-section members made from top, bottom and side plates, often with internal diaphragms for torsional rigidity and biaxial stiffness.
Heavy Steel Bridge Components include fabricated plate girders, box-girder sections, cross girders, diaphragms, stiffeners and connection assemblies used in bridge and transport infrastructure. Components are produced to approved drawings, material requirements and project inspection plans.
