Our engineering and production teams review customer drawings, technical specifications, dimensions, material grades, welding requirements and surface treatment requirements before production.
Steel plates, beams and sections are selected according to project requirements and inspected before fabrication.
Steel plates and sections are processed using CNC plasma cutting, flame cutting, laser cutting or other suitable methods depending on material thickness and project requirements.
Connection holes, bolt holes and other machining requirements are completed using CNC drilling, punching and machining equipment.
Steel components are positioned and assembled according to approved fabrication drawings to ensure dimensional accuracy.
Experienced welders perform structural welding according to the required welding procedure.
Depending on the product, welding processes may include:
MIG Welding
MAG Welding
CO₂ Shielded Welding
Submerged Arc Welding
Manual Arc Welding
Weld appearance, size, position and quality are inspected according to project requirements.
Additional non-destructive testing can be arranged where required by the project.
Fabricated steel components can be shot blasted or sand blasted to remove rust, scale and surface contaminants before coating.
Surface protection options include:
Anti-Rust Primer
Epoxy Coating
Intermediate Paint
Finish Coating
Hot-Dip Galvanizing
Customized Anti-Corrosion Systems
Dimensions, welds, connection plates, bolt holes, surface finish and component identification are checked before packing and shipment.

We provide an integrated manufacturing process covering:
Material Preparation → Cutting → Drilling → Assembly → Welding → Surface Treatment → Inspection → Packing → Delivery
Our team can review fabrication drawings and help optimize components for manufacturing efficiency.
Different sizes, materials, thicknesses, connection details and surface treatments can be produced according to customer requirements.
Welding parameters, weld appearance and structural connections are checked during production.
Critical dimensions, hole positions, connection plates and overall component dimensions are inspected before shipment.
Customers can source multiple steel fabrication processes from one supplier, reducing coordination between different manufacturers.
Components can be marked and packed according to erection sequence, drawings or customer requirements for easier site identification.
