Press & Punch in the Door Frame Production Line

The press and punch play an important role in a hollow metal frame production line.

Normally a hollow metal door frame consists of 3 parts, the header the hinge jamb, and the strike jamb. 

In this door frame production process, the three parts are not cut-off thoroughly,  hinge holes, strike holes and the joints are punched in sequence.

After roll forming, 3 parts of the steel door frame are still connected, users just need to bend them at the joint and assemble them into a door frame.

General Description of Hollow Metal Frame Roll Forming

Hollow metal door frames are widely used in residential, commercial, and industrial buildings. Especially the places where door operating conditions are relatively bad.

Modern hollow steel door frame manufacturer has been producing a variety of stunning patterns. Some wood-like decorative galvanized steel door has both beautiful appearances of natural wood and strength of steel.

Fire-rated doors and frames play a very important role in the fire resistance of a building.  Steel hollow door is the wise choice for fire-proof.

A Stainless steel door frame is not only modern and shining but also stronger, longevity, and excellent fireproof. 

Developing with the modern metal door manufacturing, Brother Uion Machinery has been providing steel hollow door frame roll forming solutions for a variety of metal door manufacturers.

The following door profiles have been producing by machines made by Brother Union Machinery.

Glavanized Door Frame Roll Forming

Brother Union Machinery has manufactured lots of door frame making machines. 

Especially for the South African market,  dozens of metal door frame production lines are made as to the customer's requirements. These door frames are made of mild steel or galvanized steel, and after a protective paint coating, these door frames have a popular appearance and longer service time.  

For large quantity standard framing production, Compared to a press brake, a roll forming line by Brother Union Machinery is a better choice.

Steel Framing with Decorative Coating Roll Forming

Modern hollow steel frame manufacturers produce door frames, window frames with flexible decorative coatings in numerous colors and textures. These framings are more expensive, but they are better suited for residential doors. Brother Union Machinery has produced a series of door frame roll forming lines to fit the European customer's higher requirements.   

Through the roll forming process, these PVC steel sheets go into wood-like door frames, which not only have the strength of steel but also have the beautiful wood-grain textures.

Custom Hollow Metal Frame Profile

The advantage of steel door / window frame profile

  • The modulus of elasticity of steel profiles is 3 times that of aluminum alloys, and the strength of steel buildings far exceeds that of aluminum alloy profiles.

  • Steel profile has more span than aluminum alloy

  • Steel, glass, and concrete have almost the same thermal expansion coefficient, so there is no need to leave expansion joints when installing steel frame doors and windows

  • Steel frame door much better at fireproofanti-theftexplosion-proof, and bulletproof.

  • The fireproof performance of steel frame doors and windows is far better than aluminum alloy. The melting point of steel is 1500°, and the melting point of aluminum alloy is 600°.

  • Steel will not melt when exposed to fire, will not release corrosive gases, and the frame will remain stable

  • Steel profile system can meet different grade fire proof requirements

  • The steel profile is strong and stable, high load, and durable, it is the ideal choice for security application.

  • Steel profiles are suitable for high-frequency operation, such as commercial fire-rated doors.
