Built-up beam fabrication — welded plate beams when rolled sections are not enough

Built-up beams are fabricated I-sections assembled from plate — top flange, bottom flange, and web — when the required depth, weight, or span exceeds standard rolled UB/UC availability, or when the designer needs a non-standard section for a specific load case. Sun Corporation fabricates built-up beams for pipe rack longitudinals, platform girders, crane runway segments, and industrial building primary frames.
When EPC specs call for built-up sections
- Pipe rack beams spanning between bents with heavy piping clusters
- Transfer beams supporting multiple equipment lines
- Long-span platform girders in process areas
- Crane runway beams where rolled sections cannot meet IS 807 span/loading
- Plate girders for access bridges and conveyor supports
Quality controls
Each built-up beam is fabricated to approved shop drawings with piece marks linked to the GA. Flange-to-web welds are executed under qualified WPS with NDT as listed in the ITP. Camber and sweep are checked against fabrication tolerances in IS 800 Annex F before dispatch. Material is IS 2062 with MTCs in the project dossier.
Companion scope: built-up column fabrication and plate girder fabrication.
