Steel Door Frame

The Steel Door Frame are light weight, sturdy, and manufactured from Galvanized steel with the thickness from 0.9-2.0mm.

The Steel door frames can be used extensively and are often preferred to timber due to their cost efficiency as they have installation advantages over timber door frames. Metal door frames can be easily fitted during construction or retrofitted. Their overall resilience and surface finish make them a popular and often more viable option to timber.

There are 2 main kinds of steel door frames:

Single Rebate Door Frame, The Doors only can be assembled in one side of the frame

Double Rebate Door Frame, The Doors can be assembled both side of the door frame

The Corners of Steel Door Frame

1. Butted knocked down joint

2. Welded Joint

3. Mitered Joint

4. Spot Welded joint

5. Mitered welded

6. Latest design, self joint. which is widely used in steel door industry. Believe Industry Company a whole automatic roll forming machine to produce such door frame
