11 May, 2026 If you are building a new home or renovating your office, one thing is sure. You need strong and good looking door fittings. The market is full of options. But two things matter the most. First, who is a trusted mortise handle manufacturer in Delhi. Second, how to pick the right mild steel handle for your doors.
In this blog, Crown ISI will help you understand everything. We will also talk about other important items like classic door fittings accessories, Stainless Steel Hinges 304G, and Brass Tower Bolts ISI. Let us start.
Why Delhi is a Hub for Mortise Handles
Delhi has many hardware manufacturers. But not all give good quality. A good mortise handle manufacturer in Delhi uses strong raw materials. They test every handle for smooth rotation and long life. Crown ISI is one such name. We make handles that work for years without jamming or rusting.
A mortise handle is the part you push or pull to open a door. It connects to the lock body inside the door edge. So if the handle is weak, the whole door system fails.
Mild Steel Handle – The Smart Choice
Now let us talk about the mild steel handle. Mild steel is strong, cheap, and easy to shape. It does not break under pressure. That is why most builders and homeowners prefer it.
But here is the catch. A mild steel handle can rust if the coating is poor. So always buy from a trusted mortise handle manufacturer in Delhi like Crown ISI. We give powder coated or zinc plated finishes. This stops rust for many years.
How to Choose a Mild Steel Handle
- Check the thickness – Thicker steel means stronger handle.
- Look at the finish – Smooth and even coating is a good sign.
- Test the spring – The handle should come back to its place after you leave it.
- Ask for brand – Always buy from Crown ISI or similar known names.
Other Important Door Fittings You Need
A good door is not just about handles. You need complete classic door fittings accessories to make everything work smoothly. Here is what Crown ISI suggests.
Stainless Steel Hinges 304G
Hinges hold the door to the frame. If they are weak, the door will sag. Stainless Steel Hinges 304G are the best for Indian weather. Grade 304G means high nickel and chromium. No rust, no noise, no bending. Crown ISI makes Stainless Steel Hinges that fit all wooden and metal doors.
SS Butt Hinges
SS Butt Hinges are the most common type. They have two leaves that fold like a book. You can use them for bedroom, bathroom, or office doors. They are small but very strong.
Stainless Steel Welded Hinges
For heavy doors like main gates, you need stainless steel welded hinges. These hinges have welded joints. So they never open or loosen over time. Crown ISI is a leader in SS hinges making India. Our welded hinges can hold doors up to 100 kg easily.
ss 304 stainless steel butt hinges
If you want the best, ask for ss 304 stainless steel butt hinges. Grade 304 is food grade quality. It never rusts, even near the sea. Crown ISI gives you real 304 grade, not fake ones.
Brass Tower Bolts ISI
Doors also need bolts for extra safety. Brass Tower Bolts ISI are the gold standard. ISI mark means the bolt follows Indian government quality rules. Brass does not rust and looks beautiful. Use them on bathrooms, balconies, and storage rooms.
Brass Sliding Door Bolt
For sliding doors, a normal bolt will not work. You need a Brass Sliding Door Bolt. It moves left and right smoothly. Crown ISI makes these bolts with strong brass bodies and stainless steel pins.
