Zero-compromise quality inspection — every batch dimensionally verified and load-tested before dispatch.
Our quality management system is built around a zero-compromise inspection philosophy. Every batch undergoes multi-point dimensional checks, material verification and mechanical load validation before dispatch.
Full QMS covering design, production, inspection and delivery with regular third-party surveillance audits.
Approved and audited supplier to Ordnance Factory Medak (AVNL), Ministry of Defence, Government of India.
Full material traceability with mill test certificates and in-house test reports available for every supply batch.
Applied for compression, torsion and tension spring design parameters and tolerances.
BIS specification for spring steel wires used in all Indian defence and industrial supply orders.
Cold-drawn carbon steel wire standard specified for certain BHEL and ordnance applications.
High-tensile chromium vanadium alloy steel — preferred material for defence-grade compression springs.
Every production batch is checked against these parameters before dispatch.
