Aluminum alloy material has the characteristics of sturdiness, lightness, beauty, and no rust, and is currently the most widely used type of door frame. The door frame and the sealing strip groove are designed in one piece, and a good sealing effect can be achieved after wearing the sealing strip, and the track (thickness is more than 4mm) is also an aluminum profile, and the thickened aluminum profile is used. Very light, no noise when opening and closing doors, and excellent sealing performance.
It can be said that the most commonly seen in the market is the steel decorative door frame. Its price is relatively low and reasonable, but the exterior lines are hard and it is difficult to integrate with the modern interior decoration.
The copper style is advanced, and it has a good performance in terms of fire prevention, corrosion resistance, tamper resistance, and dust resistance. In terms of material, the copper door frame is the best, and in terms of price, it is also the most expensive.
Stainless steel material has the characteristics of being strong, non-rusting, high-grade, etc., but it is difficult to process and the price is high. The bending accuracy of the bending machine is not very high, and other stainless steel other than 304 stainless steel will also rust, and the sealing strip groove has to be added separately. There is no stainless steel track, and galvanized steel track is used. The phenomenon of thermal expansion and contraction is serious, the service life is short, and the application is relatively narrow.
