Cangzhou Zhongtuo manufactures professional Door Frame Making Machines for producing steel and metal door frames in different sizes and profiles. With a continuous roll forming process, the machine can shape galvanized steel and carbon steel into accurate door frame profiles while integrating feeding, punching, forming, cutting, and output into one production line.

For manufacturers serving residential, commercial, and industrial construction markets, a Steel Door Frame Roll Forming Machine offers a more efficient alternative to conventional bending methods. Moreover, Cangzhou Zhongtuo can customize the machine according to the customer’s door drawings, profile dimensions, punching requirements, and production standards.

Multi-Size Steel Door Frame Roll Forming Machine

Door frames must provide sufficient strength and dimensional stability while matching different wall structures and door sizes. Therefore, a multi-size roll forming line gives manufacturers greater flexibility when producing different frame specifications.

The machine can produce door frame profiles with widths based on customer requirements and applicable standards. The source design supports door frame widths from approximately 120–250 mm, while the forming system uses a gearbox and electric motor to process relatively thick steel materials consistently. In addition, the forming rollers are mounted on an 80 mm diameter shaft, supporting long-term production.

Depending on the required application, the machine can be configured for galvanized steel, carbon steel, stainless steel, and other suitable materials. Galvanized steel is particularly common for door frame production because of its combination of strength and corrosion resistance.

Door Frame Profiles and Automatic Punching

One major advantage of a Door Frame Roll Forming Machine is its ability to produce different frame designs on customized production lines. Depending on the customer’s drawings and market requirements, the equipment can be designed for profiles such as square bend, standard deluxe, robe, metro, shadow line, drywall, flush finish, split, single rebate, and double rebate door frames.

Furthermore, the punching system can be integrated into the production line. This allows manufacturers to create hinge holes, lock holes, and other required openings automatically during production rather than performing these operations manually afterward. The punching position can also be configured according to the door design and production requirements.

As a result, the complete line reduces additional processing steps and helps maintain consistent hole positions from one finished frame to another.

Complete Door Frame Manufacturing Process

The Steel Door Frame Making Machine combines several production stages into a continuous workflow. The standard configuration includes a manual decoiler, pre-shearing device, feeding guide, roll forming system, punching machine, cutting unit, control system, and output table.

The production process generally follows:

Manual Decoiler → Feeding → Roll Forming → Punching → Cutting → Output Table

During operation, the steel coil enters the forming line through the feeding system. The rollers gradually shape the strip into the required door frame profile. Afterward, the punching system creates the specified holes, and the cutting unit separates the finished profiles into preset lengths.

This continuous structure improves production efficiency and dimensional consistency. At the same time, the forming rollers can create a smooth finished surface without the scratches that may occur with some conventional processing methods.

Technical Specifications of Door Frame Machine

The exact machine configuration can be customized according to the customer’s profile drawings and production requirements. A typical configuration described in the source includes the following specifications:

The forming rollers use first-grade steel with heat treatment and hard chrome coating, helping the machine maintain stable forming performance during continuous operation. The standard technical configuration can also be adjusted when customers require different steel thicknesses, frame dimensions, or production speeds.

Why Choose a Door Frame Roll Forming Line?

Traditional door frame production may rely heavily on sheet bending and separate punching operations. In contrast, an integrated Door Frame Roll Forming Line combines several processes into one automated workflow.

First, the machine can continuously form steel strips into precise profiles. Second, manufacturers can integrate punching operations into the forming process, which helps improve the positioning of hinge and lock holes. Finally, the cutting system produces finished profiles at the required length.

The system is particularly suitable for steel door manufacturers, residential construction, commercial buildings, apartment projects, and other construction-related applications. By selecting the appropriate roller configuration and control system, manufacturers can also produce different frame sizes and designs according to local market requirements.

Cangzhou Zhongtuo can further customize the production line based on your door frame drawings, material thickness, profile dimensions, punching positions, and production requirements. This approach allows the equipment to fit the actual manufacturing process instead of forcing the customer to adapt to a standard machine.
