Service Overview
We manufacture heavy-duty primary steel components—including columns, rafter sections, crane beams, and portal frames—in our state-of-the-art fabrication facility. Using high-tensile steel plates and automated submerged arc welding (SAW), we create built-up members that deliver superior load-bearing capacity and seismic resistance. Every member undergoes strict quality control, non-destructive testing (NDT), and surface preparation before delivery.
Key Advantages
Automated plate cutting and Submerged Arc Welding (SAW) for deep penetration
Use of high-grade steel plates (E250/E350 Grade) with mill test certificates
Custom fabrication of tapered and straight built-up sections to match structural plans
Rigorous Non-Destructive Testing (NDT) including Ultrasonic and Dye Penetrant testing
High-performance anti-corrosive primer and finish paint systems

Frequently Asked Questions
What steel grades do you use for primary columns and rafters?▼
We use high-tensile steel plates complying with IS 2062 E250 and E350 grades, as well as ASTM standards, depending on the client's specifications and load requirements.
How do you ensure the quality of welds in primary members?▼
All our welders are certified to AWS D1.1 standards. We perform Ultrasonic Testing (UT) on 100% of full-penetration butt joints, alongside daily visual and dye-penetrant testing.
