New Star Industries is a trusted HSFG Bolts manufacturer in Ludhiana, Punjab, supplying High Strength Friction Grip Structural Bolts for critical steel structures across India. Our HSFG bolts are manufactured using quality-approved raw materials and precision-controlled processes to ensure consistent mechanical properties, dimensional accuracy, and dependable joint performance.
As a trusted HSFG Bolts manufacturer in Ludhiana, New Star Industries has been supplying High Strength Friction Grip structural fasteners to India's most demanding civil and railway infrastructure projects since 1961. Our bolts are tightened to a controlled preload that generates a massive clamping force, transferring loads entirely through friction between connected surfaces — eliminating joint slip and providing far superior structural performance compared to ordinary bolts.
Manufactured at our Ludhiana facility in Punjab, every HSFG bolt undergoes rigorous quality control to meet IS 3757, EN 14399, and ASTM A325 standards — making them the preferred choice for railways, bridges, high-rise steel frames, and infrastructure tenders across India.
Our HSFG bolts carry RDSO approval, making them eligible for Indian Railways projects, bridge tenders, and government infrastructure procurement. The heavy hex head (8.8S / 10.9S) distributes clamping force over a larger bearing area, protecting structural plates from deformation under high preload.
Nuts are prevented from loosening because bolts are tensioned to proof load — ideal for railway bridges and structures subjected to constant dynamic loads.
High inherent material strength reduces fire hazards and structural failure risk. Friction-grip mechanism prevents any relative movement between joined plates.
Fewer bolts achieve the same structural strength compared to ordinary bolts, reducing material costs, installation time, and overall project manpower requirements.
Tightened with calibrated torque wrenches rather than pneumatic hammers — significantly lower installation noise, meeting urban project site requirements.
Our HSFG bolts from Ludhiana are supplied to major infrastructure and industrial project types across India:
| Industry / Project Type | Role of HSFG Structural Bolts |
|---|---|
| Railway Bridges & Girders | RDSO-approved HSFG bolts for fatigue-resistant connections in composite girder and truss bridges under dynamic rail loads. |
| Highway & Flyover Bridges | Friction-grip joints that resist slip under heavy traffic loads and vibration, ensuring long-term structural integrity. |
| Steel High-Rise Buildings | Connecting steel columns, beams, and bracing in moment-resisting and braced frame systems with controlled preload. |
| Industrial & Power Plants | Heavy-duty structural connections in boiler supports, turbine platforms, and crane runway girders. |
| PEB & Steel Fabrication | Column base plates, rafter connections, and mezzanine floor framing in pre-engineered buildings. |
