From cable trays to
defence-grade parts.
One direct manufacturer across three procurement groups — electrical infrastructure, structural and industrial, precision and custom.
Electrical Infrastructure
Cable management, earthing, busbars, and protection hardware engineered to IEC, NEMA, BS and IS for utilities, data centres and EPC projects.
View group StructuralStructural & Industrial
Electroforged gratings, fabricated supports, tower assemblies, and solar mounting — galvanized for service life in heavy industrial environments.
View group PrecisionPrecision & Custom
Multi-axis CNC components, sheet-metal and deep-drawn parts, and defence-grade precision work held to ±0.01 mm under single-facility control.
View group
Cable Trays
Ladder, perforated, and raceway cable trays roll-formed in MS, GI, SS and aluminium — sized and finished to project load and environment.

Earthing & Grounding Systems
Earthing plates, pipes, rods/electrodes, and copper/GI strips and wire for safe, low-impedance grounding of plant and buildings.

Electroforged Gratings
Electroforged and press-locked steel gratings to IS 2713 for walkways, platforms and industrial flooring — galvanized for service life.

Tower Fabrication & Assemblies
Angle and tubular tower members and assemblies — cut, punched, formed and galvanized for transmission, telecom and solar structures.

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.
Certifications & standardsProcurement

Cable Tray as an Equipment Grounding Conductor: Standards and Compliance
Steel cable tray systems can function as an Equipment Grounding Conductor (EGC) under NEC 392.60 and IEC 61537, reducing the need for separate bonding conductors. This guide covers the criteria that must be met, how to verify continuity, and where the practice is not permitted.
Read guideIS 3043 Earthing Standard: A Practical Compliance Guide
IS 3043:2018 is India's primary earthing standard, covering electrode selection, earth resistance targets, earthing conductor sizing, and inspection requirements. This guide translates the standard's clauses into practical compliance steps for substation and industrial plant engineers.
