The Three-Step Project Supply Plan.
Simple, transparent, and built to eliminate procurement delays. Here is exactly how we deliver from our Howrah works to your site.
Submit Specs & Drawings
Send your technical drawings, standard codes (IEC/ASTM/IS), and required gauges. Our Howrah engineering team performs a feasibility check within 24 hours.
Receive QA Plan & Quotation
We provide an itemized quote detailing exact weights, steel grades, and hot-dip micron options alongside our custom Quality Assurance Plan (QAP).
Direct Port Dispatch
Your order is fabricated, in-house galvanized, inspected by SGS/TUV, and containerized at Kolkata Port for direct ocean shipment to your destination.
The Sourcing Conflict: Factory Direct vs Sourcing Agents
When middle-men and trading houses stand between you and the welding floor, project specifications get lost in translation and prices carry heavy, hidden markups.
Why direct Howrah fabrication is the safest decision for your grid:
Standards-based engineering, certified.
Built to international specification and inspected in-house, with the documentation procurement teams need to sign off.
