Metal Accordion Security Doors

1. The folding door is composed of a door frame, a door sash, a transmission component, a rotating arm component, a transmission rod, an orientation device, etc. The door panels are made of aluminum alloy extruded profiles and can be installed both indoors and outdoors.

2. The folding door has chemical stability such as light door body, thermal insulation, cold and heat insulation, moisture-proof, fireproof and flame retardant, noise reduction and sound insulation, acid and alkali resistance, and corrosion resistance. It does not stick to oil smoke, is easy to clean, is not easy to change color, and is also suitable for kitchen, bathroom, toilet and other occasions. Easy and fast installation, long service life and easy maintenance, thus making the use of folding doors more extensive.

Q: What is the difference between ordinary aluminum alloy profiles and thermal break aluminum alloy profiles?

A: The color of ordinary aluminum profile is single, the whole is a conductor, and the heat transfer and heat dissipation are relatively fast; The color of the thermal break aluminum profile is diversified, and the two ends are connected with PA66 nylon insulation strips to form a thermal insulation layer, and the temperature difference between the inside and outside is different, which will not transfer heat and play the role of heat preservation and energy saving.

Q: What is the wall thickness standard of aluminum alloy door and window profiles?

A: The wall thickness of the aluminum alloy window profile is not less than 1.8mm, the wall thickness of the inner window profile is not less than 1.4mm, and the thickness of the profile can be increased for high-rise buildings, the wall thickness of the main stressed part of the heavy-duty sliding door profile is not less than 2.0mm, the thickness of the outer swing door profile is not less than 2.2mm, and the thickness of the inner swing door profile is not less than 2.0mm, which is the mandatory requirement of the 2020 version of the national standard GB/T4878-2020, and the single door and window can be thickened if it exceeds 3M²-4M². Excessively large columns can be added to increase their physical strength.

Q: What are the advantages of aluminum alloy doors and windows? What are the surface treatments?

A: The advantage of aluminum alloy doors and windows is that they will not oxidize, rust, and are durable; The anti-corrosion treatment of the surface of aluminum alloy includes porcelain swimming, electrophoresis, powder painting, and PU wood grain spraying, among which the effect of fluorocarbon paint is better, which can be combined with the profile and become a part of the profile, and it is a super anti-corrosion outer layer.
