Why can aluminum alloy doors and windows occupy the market?

17 Jun, 2021

Doors and windows made of aluminum alloy extruded profiles as frames, stiles, and fan materials are called aluminum alloy doors and windows, or aluminum doors and windows for short. Including aluminum-wood composite doors and windows that use aluminum alloy as the base material of the load-bearing rod (the rod that bears and transfers its own weight and load) and wood and plastic, referred to as aluminum-wood composite doors and windows. The quality of aluminum alloy doors and windows can be roughly judged from the selection of raw materials (aluminum profiles), aluminum surface treatment and internal processing quality, and the price of aluminum alloy doors and windows.

1. Materials

The thickness, strength, and oxide film of aluminum profiles used for high-quality aluminum alloy doors and windows should comply with relevant national standards. The wall thickness should be 1.2 mm or more, the tensile strength should reach 157 Newtons per square meter, and the yield strength should reach per square meter. 108 Newtons per square millimeter, the thickness of the oxide film should reach 10 microns. If the above standards are not met, the doors and windows of inferior aluminum alloy cannot be used.

2. Processing

High-quality aluminum alloy doors and windows, fine processing, careful installation, good sealing performance, and easy opening and closing. Inferior aluminum alloy doors and windows, blindly select aluminum profile series and specifications, processing indiscriminately, using sawing instead of milling, not installing as required, poor sealing performance, uncomfortable opening and closing, not only leakage of wind and rain, glass explosion, but also In strong winds and external forces, it is easy to scrape or knock the sliding parts or glass off, destroying objects and injuring people.

3. Price

In general, due to the high production cost of high-quality aluminum alloy doors and windows, the price is more than 30% higher than that of inferior aluminum alloy doors and windows. Some aluminum alloy doors and windows made of aluminum profiles with a wall thickness of only 0.6-0.8 mm have a tensile strength and yield strength that are much lower than the relevant national standards and are very unsafe to use. In addition, there are many self-employed people who process aluminum alloy doors and windows, and they do not understand the structural characteristics and performance of aluminum alloy doors and windows. In order to reduce the cost and cut corners and shoddy materials, the product has a greater hidden danger and is generally not suitable for use. It is best to choose products from regular aluminum alloy doors and windows manufacturers. Here is a special note: the current national standard profile thickness is 1.4mm, if the supplier chooses 1.2mm or 1.0mm wall thickness or even thinner materials, they are all substandard products, please buy Attention.
