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.
Welded Steel Structure Fabrication provides customized manufacturing of structural steel components for industrial, commercial, infrastructure and steel building projects.
Structural Steel Beam and Column Welding Service is a professional welding processing service for customer-supplied or customer-specified steel components. ZSJH performs beam and column welding for customer-supplied structural steel members, with welding method, joint preparation and inspection arranged according to approved drawings and project requirements
Structural Steel Primer Painting Service provides base corrosion-protection primer application for fabricated steel members. The service covers the agreed preparation, application, curing and inspection stages for fabricated structural steel supplied or specified by the customer.
Steel Beam and Column Shot Blasting Service prepares H-beams, welded beams, box columns and large load-bearing members 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) Welded Steel Components are repeatable welded parts and subassemblies produced to customer drawings, samples and brand requirements. ZSJH manufactures non-standard steel parts for OEM customers under customer-controlled drawings, specifications, samples and revision requirements.
Custom Welded Structural Steel Assemblies are finished project-specific welded and assembled steel components. The product is supplied as a completed structure or component, not as a standalone welding service. ZSJH combines beams, columns, plates, braces, stiffeners and connection details combined into ready-to-install assemblies and delivers the assembly ready for transport, installation or equipment integration.
Hot-Dip Galvanized Steel Frames are complete galvanized frames for outdoor buildings and industrial structures. 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(Computer Numerical Control) Plasma Steel Cutting Service uses programmed plasma equipment to cut CAD profiles in carbon steel. It supports fast, accurate production of plates, brackets, gussets, stiffeners and structural parts.
Base plates transfer column or equipment reactions into concrete foundations. They are cut, drilled, slotted, beveled and finished to approved drawings, with anchor-bolt layouts, leveling details and stiffeners coordinated for site installation.
Custom Welded H-Shaped Steel Columns are open H-section load-bearing members fabricated from web and flange plates. Their depth, flange width, thickness, length and connection details can be optimized for building loads and grid dimensions instead of being limited to standard rolled sizes.
Custom Welded H-Beam Fabrication provides project-specific H-shaped structural members fabricated from web and flange plates. It is a practical solution when standard rolled sections cannot meet the required depth, flange width, load capacity or connection details.
Prefabricated Industrial Structural Steel Frames are manufactured in controlled workshop conditions and supplied as marked members or frame subassemblies. Accurate fabrication and planned connection details help simplify transportation and site erection.
