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.

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.
