WHAT WE FABRICATE

Structural Steel Beams, Columns & Built-Up Sections

We fabricate primary structural steel components based on project drawings and technical specifications. Each component is reviewed by our engineering team before production, marked per erection drawings, and packed with matching material documentation.

Steel Columns

H-section columns, box columns, tapered columns and built-up columns with base plates, connection plates and bolt holes fabricated to drawings.

Steel Beams

Welded H-beams, roof beams, floor beams and crane girders with stiffeners, camber and connection details per structural design.

Welded H Sections

Custom-welded H-sections to specified dimensions, web and flange thicknesses, suitable for long-span and heavy-load structural applications.

Box Columns

Welded box-section columns with internal stiffeners, access holes and connection details for high-rise and heavy industrial buildings.

Built-Up Sections

Custom built-up steel sections, plate girders and composite members fabricated per project requirements and connection design.

Connection Components

Connection plates, stiffeners, splice plates, base plates and end plates with precise drilling and welding per connection design.

FAQ

Frequently Asked Questions

Yes. ZhongSai can review structural drawings, shop drawings and BOQ for fabrication quotation and project supply. Our engineering team verifies the component list, connection details and fabrication requirements before providing a quote.

For an accurate fabrication quote, please provide: structural drawings or shop drawings, BOQ/BOM with component list, project country, required design standard, surface treatment requirements, and delivery destination. The more detail provided, the faster we can review and respond.

Yes. Every fabricated component is marked per erection drawings for on-site identification and assembly sequence. Marking includes component numbers, orientation indicators and project reference. A detailed packing list is delivered alongside the shipment.

Yes. Components are bundled and packed for container shipment with bundle labeling, packing lists and container loading plans. We optimize packing for safe transport, customs clearance and efficient unloading at destination. Container loading support is part of our export service.

Yes. If you have preliminary design drawings but not fabrication-ready shop drawings, our engineering team can provide detailing support, including shop drawings, connection details and BOM. Detailing is connected to our fabrication capability, ensuring drawings are production-ready.

ZhongSai provides overseas installation technical guidance, including erection drawings, assembly instructions, video support and engineer on-site guidance when required. Local construction and erection are performed by the customer's or local installation team. We do not act as a local general contractor.
