Heavy Steel Fabrication

Our Heavy Steel Fabrication service delivers large, high-strength structural components for demanding industrial and infrastructure projects. We manufacture heavy beams, columns, trusses, box sections, equipment supports, platforms, and complex welded assemblies according to approved drawings and load requirements. Our capabilities include thick-plate CNC cutting, beveling, drilling, assembly, welding, straightening, machining, shot blasting, painting, galvanizing, inspection, and export packaging. With controlled fabrication procedures, qualified welders, and strict dimensional and weld inspections, we provide reliable components for factories, bridges, mining facilities, energy projects, heavy machinery, and large-span structures.


  • Heavy Steel Fabrication for Industrial & Construction Projects
    Heavy Steel Fabrication provides customized manufacturing of large and heavy structural steel components for industrial, commercial, infrastructure, and construction projects. The fabrication process typically includes cutting, drilling, forming, fit-up, welding, straightening, surface treatment, and inspection. Steel beams, columns, built-up sections, frames, trusses, platforms, and other heavy steel components can be fabricated according to customer drawings and project requirements.
  • Heavy Structural Steel Components
    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.
  • Heavy-Duty Industrial Equipment Frames
    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.
  • Heavy-Duty Equipment Support Platforms
    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.
  • Heavy Steel Bridge Components
    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.
  • Heavy Long-Span Steel Trusses
    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.
  • Heavy Industrial Steel Modules
    Heavy Industrial Steel Modules combine structural framing, equipment supports, platforms and access systems into transportable prefabricated units. Modules are manufactured to customer drawings and can be delivered as structural frames, equipment skids or multi-level process modules.
