Our Range

Spring Solutions for Every Industry

From automotive to aerospace, we manufacture springs that meet the most demanding specifications.

Helical Coil Spring

Helical Coil Spring

Open-coil helical springs wound from high-quality wire. The most common spring type, used across automotive, HVAC, and industrial machinery applications.

  • Consistent coil pitch & diameter
  • Carbon, alloy & stainless steel
  • Custom wire gauges available
Know More →
Leaf Spring Suspension

Leaf Spring Suspension

Multi-layer flat springs designed for vehicle suspension systems. Absorb road shocks and support heavy axle loads in trucks, buses, and trailers.

  • Multi-leaf & mono-leaf variants
  • High-carbon spring steel
  • Heavy load & OEM-spec builds
Know More →
Railway Bogie Spring

Railway Bogie Spring

Heavy-duty coil springs engineered for railway bogie assemblies. Designed to withstand extreme dynamic loads, vibration, and long service cycles on rail networks.

  • Meets EN 13298 rail standards
  • Shot-peened for fatigue life
  • Load-tested & certified
Know More →
Volute Spring

Volute Spring

Conically wound flat-strip springs that compress within themselves. Ideal for machinery requiring a compact, high-force solution with built-in vibration damping.

  • Self-damping under load
  • Compact compressed height
  • Flat strip or wire construction
Know More →
Tension Spring

Tension Spring

Closely wound coil springs with return hooks that store energy under extension. Widely used in garage doors, trampolines, and medical equipment.

  • Precision hook formation
  • High tensile strength wire
  • Multiple end-type options
Know More →
Conical Spring

Conical Spring

Tapered coil springs that collapse to a very flat height. Excellent where a low solid height and progressively increasing resistance is required.

  • Low solid / compressed height
  • Progressive rate behaviour
  • Used in buttons & valves
Know More →
Disc Spring

Disc Spring

Also known as Belleville washers — conical disc springs that deliver very high forces in tight spaces. Commonly stacked in series or parallel for different load curves.

  • High load in minimal space
  • Stackable series/parallel
  • DIN 2093 compliant
Know More →
Torsion Spring

Torsion Spring

Springs that work with twisting or rotary motion, exerting torque when the arms are deflected. Used in hinges, clothespins, vehicle tailgates, and industrial machinery.

  • Precise torque characteristics
  • Left & right-hand wind
  • Tight angular tolerances
Know More →
Heavy Duty Coil Spring

Heavy Duty Coil Spring

Extra-heavy industrial coil springs built for severe-duty environments. Handles extreme compressive loads in mining, construction, and heavy press machinery.

  • Wire dia. up to 50mm
  • Shot-peened & stress-relieved
  • Built to customer spec & load
Know More →
Pipe Support

Pipe Support

Engineered pipe support assemblies that carry the dead weight of piping systems while allowing controlled thermal movement. Essential in power plants, refineries, and chemical plants.

  • Variable & constant load types
  • Thermal expansion compensation
  • ASME / MSS SP-58 standards
Know More →
Spring Support

Spring Support

Coil-spring-based pipe hangers and supports that absorb vibration and accommodate vertical pipe movement caused by temperature changes and pressure fluctuations.

  • Variable & constant hanger types
  • Pre-set load configurations
  • Suitable for high-temp pipelines
