QUALITY IN
EVERY PIECE
Quality is not an afterthought at Tirupati Associates — it's engineered into every step of our process. From incoming raw material inspection to final pre-shipment checks, we follow a rigorous, documented quality control process.
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 Associates, you're not just getting hinges — you're getting assurance of long-term reliability, safety, and value on every export shipment.
