China was introduced in the 1980 s and rapidly swept across China. Plastic steel doors and windows occupied a huge share of more than 80% in the field of doors and windows. The following editor will briefly introduce the structure of plastic steel doors and windows, the advantages and disadvantages of plastic steel doors and windows, which is believed to be helpful for everyone to understand plastic steel doors and windows.
Plastic steel doors and windows originated in Europe and Germany. A former military empire had strong military manufacturing capabilities. In peacetime, it was obviously unnecessary to produce a large number of weapons, especially the defeated countries, it limits the production of weapons at all. Where can we do it? Naturally, it is a variety of civil fields.
In the 1950 s, Germany took the lead in developing this plastic steel door window profile made of upvc + alloy. China was introduced in the 1980 s and rapidly swept across China. Plastic steel doors and windows occupied a huge share of more than 80% in the field of doors and windows. The following editor will briefly introduce the structure of plastic steel doors and windows, the advantages and disadvantages of plastic steel doors and windows, which is believed to be helpful for everyone to understand plastic steel doors and windows.
First look at the structure of plastic steel doors and windows
internal structure diagram of plastic steel doors and windows
yes, what you see is wrapped outside is all hard plastic, only in the cavity that needs reinforcement, supporting steel to increase strength and stability;
advantages and disadvantages of plastic steel doors and windows
compared with previous pure steel or wooden doors and windows, this kind of profile has the following obvious advantages:
1, better thermal insulation;
plastic itself is a poor conductor of heat energy, so compared with metal material, plastic steel can well isolate the temperature inside and outside. When doors and windows are closed, it is guaranteed that the indoor temperature is 10 degrees higher than the outdoor temperature in winter, summer is lower than outdoor 5-8 degrees.
2, it has richer colors and expressive force;
the color of plastic can be rich and colorful, and even the surface film can be made into a variety of wood-like appearance, which is fake and real with various styles.
3, lower prices;
the price of plastic is obviously lower than that of alloy and metal materials with the same dosage, especially in today's rising price of metal raw materials, the price advantage of plastic steel is very obvious.
With more extensive and in-depth use, plastic steel doors and windows have gradually shown their shortcomings and shortcomings:
1. Because it is made of plastic material, combustion will produce harmful gases;
2. The surface is easy to be scratched;
3. Hardness is not enough, rigidity is not strong, long time use, easy to aging deformation;
the structure of plastic steel doors and windows, the advantages and disadvantages of plastic steel doors and windows are introduced here, for more door and window products and related knowledge, please continue to pay attention to Zhonghua door and window network.
