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 Steel Plate Welding Service is a professional welding processing service for customer-supplied or customer-specified steel components. ZSJH performs welding service for thick plates, heavy built-up members and high-load steel parts, with welding method, joint preparation and inspection arranged according to approved drawings and project requirements.
Zinc-Rich Primer Coating Service provides zinc-rich primer application for enhanced corrosion protection of properly prepared steel. The service covers the agreed preparation, application, curing and inspection stages for fabricated structural steel supplied or specified by the customer.
Welded Steel Assembly Shot Blasting prepares welded frames, brackets, nodes, stiffened components and assembled steel parts 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) Steel Equipment Bases are equipment bases, mounting platforms and installation frames made to customer interface requirements. ZSJH manufactures non-standard steel parts for OEM customers under customer-controlled drawings, specifications, samples and revision requirements.
Welded Tubular Steel Structures are completed pipe and hollow-section structures with welded nodes. The product is supplied as a completed structure or component, not as a standalone welding service. ZSJH combines circular pipes, square tubes and rectangular hollow sections formed into frames, trusses and supports and delivers the assembly ready for transport, installation or equipment integration.
Hot-Dip Galvanized Steel Trusses are galvanized roof, canopy and outdoor truss assemblies with protected members and welded nodes. 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.
Welded Steel Plate Girders are deep fabricated beams made from separate web and flange plates. They provide an efficient solution for long spans, heavy bending and high shear demands that exceed the economical range of common rolled profiles.
Custom Steel Connection Plates are finished interface components used to join beams, columns, braces and secondary steelwork. Hole groups, end geometry, plate thickness, weld preparation and match marks are produced from coordinated connection drawings.
Custom Cruciform Steel Columns use intersecting plates or welded H-sections to form a cross-shaped profile. The geometry distributes stiffness around two principal axes and can provide efficient support at framing intersections, architectural corners and heavily loaded column lines.
Heavy-Duty Equipment Support Platforms provide elevated structural support and safe operating access for machinery, vessels and process systems. Platforms are customized to customer drawings and may integrate primary framing, columns, bracing, steel grating, stairs, ladders, guardrails and equipment mounting points.
