18 Apr, 2026 When you choose a hinge for your door, you want strength and long life. That is why Stainless Steel Welded Hinges are the first choice for homes, offices, and factories. In India, the demand for strong and rust-free hinges is growing fast. And one name that stands behind quality is Crown ISI.
In this blog, you will learn the full process of SS hinges making India. We will also explain why Stainless Steel Hinges 304G and SS Butt Hinges are better for your doors. Let us start from the beginning.
Why Stainless Steel Welded Hinges?
A welded hinge is not like a regular pressed hinge. In stainless steel welded hinges, every part is joined with high heat and pressure. This makes the hinge one solid piece. There is no gap, no weak point, and no rust starting from inside.
That is why builders and homeowners trust Crown ISI for their classic door fittings accessories. Because a door opens and closes thousands of times. Only a welded hinge can take that daily load without breaking.
The Full Process of SS Hinges Making India
Making a high-quality Stainless Steel Hinge is not easy. It takes skill, good machines, and strict checking. Here is the step-by-step process used by Crown ISI for SS hinges making India.
Step 1: Choosing the Right Raw Material
Everything starts with the metal. For Stainless Steel Hinges 304G, we use grade 304 stainless steel. This grade has 18% chromium and 8% nickel. It does not rust, even in humid weather. Many cheap hinges use low-grade steel. But Crown ISI never compromises here.
Step 2: Cutting and Shaping
The steel sheets are cut into small flat pieces. These pieces become the left leaf, right leaf, and the knuckles (the round parts where the pin goes). High-pressure machines punch the exact shape. Every piece is checked for smooth edges.
Step 3: Creating the Knuckles
This is the most important step for stainless steel welded hinges. The knuckles are rolled perfectly round. Then they are welded onto the leaf. Welding is done with argon gas shielding. This keeps the weld clean and strong. No gap means no water entry. No water means no rust.
Step 4: Assembly and Pin Insertion
Now the two leaves are placed together. The knuckles interlock. A polished stainless steel pin is inserted through the middle. This pin is also made of 304G grade. In SS Butt Hinges, the pin is removable for door fitting. In welded hinges, the pin is tight and permanent.
Step 5: Grinding and Polishing
After welding, there are small rough marks. Skilled workers grind every weld smooth. Then the whole hinge is polished. The finish can be satin (matte) or mirror (shiny). Crown ISI gives both options in their classic door fittings accessories collection.
Step 6: Quality Testing
Every hinge goes through a load test. We open and close it 50,000 times on a machine. We also do a salt spray test for 200 hours. This ensures Stainless Steel Hinges 304G will not rust for years. Only after passing all tests, a hinge gets the Crown ISI stamp.

Frequently Asked Questions (FAQ)
1. What is the difference between welded hinges and normal hinges?
Normal hinges are pressed and have gaps. Welded hinges have joints fused with heat. No gap means stronger and no rust.
2. Why is 304G stainless steel better for hinges?
304G has high chromium and nickel. It does not rust in rain, humidity, or coastal air. Cheap hinges use 200 series steel which rusts fast.
3. Are Crown ISI hinges really made in India?
Yes. Crown ISI manufactures all stainless steel welded hinges in our Indian factory. We control quality from raw material to final packing.
4. Can I use SS Butt Hinges for a heavy main door?
For normal main doors, yes. But for very heavy wooden doors above 60 kg, use stainless steel welded hinges for extra safety.
5. How do I know a hinge is welded or pressed?
Look at the knuckles. If you see a smooth continuous line without any gap, it is welded. If you see a gap or loose fitting, it is pressed.
6. What is the warranty on Crown ISI hinges?
We give 5 years of warranty against rust, breaking, or welding failure. No other brand in India gives this confidence.
7. Do you make classic door fittings accessories other than hinges?
Yes. Crown ISI makes tower bolts, door handles, and latch sets in matching stainless steel finish.
