Product Overview

Heavy Steel Fabrication is heavy-section steel fabrication for large welded members, industrial structures and load-bearing assemblies. It is supplied as a project-specific solution rather than a fixed catalogue item. Geometry, member sizes, connections, protection systems and delivery segmentation are confirmed from approved documents.
The engineering and fabrication scope can coordinate transport envelopes, lifting points, equipment supports and site splice locations. Early review of drawings, loads, site conditions and transport limits helps define a practical supply package and reduces interface risk.

Key Features

- Project-specific engineering: The heavy steel fabrication is developed around heat input, distortion control, lifting geometry and heavy-section weld quality; final member sizes and details follow approved calculations and drawings.
- Coordinated interfaces: Design and detailing account for transport envelopes, lifting points, equipment supports and site splice locations, reducing conflicts during fabrication and site assembly.
- Controlled prefabrication: CNC processing, documented fit-up and controlled welding improve dimensional consistency and traceability before shipment.
- Connection detailing: Bolted, welded and bearing interfaces are coordinated with the actual load path, access, tolerances and erection method.
- Inspection planning: Material verification, dimensional checks, weld inspection and specified NDT are tied to the approved quality plan.
- Delivery-ready documentation: Member marks, packing lists, inspection records and erection information are prepared to match the agreed supply scope.
