18 Apr, 2026 When you choose hinges for your doors, you want strength, smooth movement, and no rust over time. That is whySS Butt Hinges and SS 304 stainless steel butt hinges are the first choice for homes, offices, and factories in India.
But not all hinges are made the same. Some look shiny outside but fail after a few monsoons. Others feel heavy but do not fit your door properly.
This guide gives you simple, practical buying tips. You will learn what to check, why material matters, and how Crown ISI makes some of the best Stainless Steel Hinges in the market.
Let us start with the most common question.
What Are SS Butt Hinges?
SS Butt Hinges are rectangular metal pieces with two leaves and a central pin. They fit into the gap between a door and its frame. The word "butt" comes from the way the two surfaces butt against each other.
These hinges are used for:
- Wooden doors
- Metal cabinets
- Heavy main doors
- Bathroom and kitchen shutters
When you buy SS Butt Hinges made from SS 304 stainless steel butt hinges grade, you get high corrosion resistance and load-bearing capacity.
Why Choose SS 304 Stainless Steel Butt Hinges?
Not all stainless steel is the same. Grade 304 is the most trusted for door fittings because:
- It contains 18% chromium and 8% nickel
- It does not rust even in humid or coastal areas
- It handles heavy door weight without bending
- It keeps its polish for years
Many people search for Stainless Steel Hinges 304G – the "G" stands for grade. Always ask your supplier for the grade certificate.
At Crown ISI, we use only genuine SS 304 for all our Stainless Steel Hinges. That is why our SS hinges making India process follows strict quality checks.
7 Buying Tips for SS Butt Hinges (Easy & Practical)
Here is what you must check before buying any SS Butt Hinges.
1. Look for the Grade Mark
A genuine hinge will have "SS 304" or "304G" engraved. If you see no mark, do not buy.
2. Check the Thickness
Thickness is measured in gauge or mm. For a main wooden door, use 2.0 mm to 2.5 mm. For light cabinets, 1.2 mm is enough.
3. See the Pin Construction
The pin should be of the same SS 304 material. Some cheap hinges use iron pins with a steel coating. Those will rust within months.
4. Ask for Welded Hinges for Heavy Doors
If your door is over 40 kg, use stainless steel welded hinges. Welded hinges have no removable pin. They are stronger and cannot be forced open from outside.
5. Match the Finish
Most SS Butt Hinges come in satin, mirror, or brushed finish. Choose one that matches your classic door fittings accessories like handles and towers.
6. Buy from a Trusted Indian Manufacturer
Local quality is often better than cheap imports. Crown ISI is known for SS hinges making India with consistent thickness and perfect drilling.
7. Pair with Good Bolts
Even the best hinge is useless if your locking is weak. Use Brass Tower Bolts ISI for the top and bottom of doors. For sliding doors, pick Brass Sliding Door Bolt with smooth action.

How to Maintain Your SS 304 Stainless Steel Butt Hinges
Good hinges do not need much work. But a little care makes them last longer.
- Wipe with a dry cloth once a month
- Do not use hard chemicals or steel wool
