ISO 9001:2015
CERTIFIED
Quality is not an afterthought at Tirupati Hinges & Hardware Exports — it's engineered into every step of our process. From incoming raw material inspection to final pre-shipment checks, we operate a rigorous quality management system certified to ISO 9001:2015.
Whether it's SS 304, SS 316, brass, or zinc alloy hinges, we guarantee consistent quality and flawless performance in every piece. Defective or subpar products never leave our facility — ensuring our clients receive only the best.
Testing & Quality Control
Every batch is tested in a salt spray chamber for up to 1,000 hours to verify corrosion resistance in coastal and humid export markets.
Hinges are cycled 200,000+ times under load to simulate years of real-world door use before a design is approved for production.
Coordinate Measuring Machine checks confirm every hinge meets exact tolerances — critical for consistent fit across bulk orders.
Incoming raw material (SS 304, SS 316, brass, zinc alloy) is verified for grade and hardness before it enters production.
Every finish — polished, brushed, PVD, powder-coated — is inspected for consistency, scratches, and plating adhesion.
Before any export order is packed, a final QC pass checks quantity, labeling, and packaging integrity — with photo/video proof provided to the buyer.
Quality Built In, Not Inspected In
Our in-house QC team is equipped with advanced testing tools and follows documented procedures aligned with international standards at every stage of production — not just at final inspection.
With Tirupati Hinges & Hardware Exports, you're not just getting hinges — you're getting assurance of long-term reliability, safety, and value on every export shipment.
