Built on Steel. Driven by Precision.
Steel Stone Infra Private Limited is a New Delhi-based steel fabrication and supply company serving India's industrial sector for over 15 years.
From a Single Workshop to a Pan-India Steel Partner
Steel Stone Infra Private Limited was founded in New Delhi with a singular focus: to bring precision, reliability, and technical expertise to India's industrial steel supply chain. What began as a small fabrication workshop has grown into a full-service steel company trusted by plant engineers, EPC contractors, and procurement managers across the country.
Over the years, we have built deep relationships with India's leading steel mills — SAIL, Tata Steel, JSW, and RINL — giving our clients direct access to certified, traceable materials at competitive prices. Our in-house fabrication facility in Delhi NCR handles everything from structural steel components to complex custom process equipment.
Today, Steel Stone Infra operates across four core service lines: structural fabrication, steel supply and distribution, custom fabrication, and project-based supply management. Every order we fulfill carries the same commitment to quality and on-time delivery that has defined us from day one.
What We Stand For
Precision First
Every component we fabricate and every tonne we supply is held to exact specifications. We do not compromise on dimensional accuracy or material quality.
Full Traceability
All materials are sourced from BIS-certified mills with full mill test certificates. Our clients always know exactly what they are getting.
On-Time Delivery
We understand that project delays cost money. Our logistics network and inventory management are built around keeping your timeline intact.
Technical Partnership
We work as an extension of your engineering team — reviewing drawings, suggesting material optimizations, and solving problems before they reach the shop floor.
Long-Term Relationships
Most of our clients have been with us for over five years. We earn trust through consistent performance, not just competitive pricing.
Safety & Compliance
All fabrication work follows applicable IS codes and safety standards. Our facility maintains a strong safety record across all operations.
Certified. Compliant. Accountable.
Steel Stone Infra operates under a rigorous quality management framework. All materials are sourced from BIS-certified mills and are accompanied by full material test certificates. Our fabrication processes comply with applicable Indian Standards (IS codes) and international welding codes where required.
