Built-up column fabrication — welded plate columns for heavy plant steel
Built-up columns are fabricated vertical members made from plate — I-section columns with plate flanges and web, or box columns for high compression and bi-axial loading. They appear throughout process plants on pipe rack bents, equipment support frames, and multi-storey industrial structures where rolled UC sections are insufficient. Sun Corporation fabricates built-up columns at our Hyderabad workshop with the same WPS/PQR and inspection regime as our beam and rack work.

Hyderabad and pan-India supply
Columns are often the heaviest single pieces in a rack bent. We plan lift weights, transport permits, and site erection sequence with the EPC construction manager before fabrication release. Local supply from Jeedimetla suits Telangana and Andhra Pradesh industrial corridors; we dispatch built-up columns pan-India with our logistics coordination.
