The door is one of the indispensable building materials in the home improvement. The types and materials of the doors on the market are different. There are wooden doors, plastic steel doors, tempered glass doors, and aluminum alloy doors. In recent years, steel doors have been widely used in interior decoration. So when does the steel door? What about plastic doors? The following Xiao Bian will share these issues with you and look forward to helping friends with the need.
Plastic steel door how
Plastic steel doors are not new products. They were already available in the 1950s. At the very beginning, the steel doors used a single cavity structure, which was relatively simple and rough. Along with the world energy crisis in 1972, steel doors and windows with good energy-saving effects were used in the early 1970s. At present, plastic steel doors have been recognized by consumers all over the world. There are South Korea, Taiwan, Singapore, and Thailand that use plastic steel doors and windows in Asia.
Plastic steel door how
We have come to look at the development of plastic steel doors in China. The domestic plastic steel doors started relatively late and began production in the 1970s. However, the real maturity of technology began with the introduction of advanced equipment in 1983. Nowadays, there are more than 2,000 profile extrusion lines, more than 400 profile factories, and more than 3,000 assembly plants. In 1999, the profile production capacity was 800,000 tons, and the annual assembly of door and window capacity was 60 million square meters, which has now become the number currently in China. Not much rapid development of the industry. At present, plastic steel doors have been accepted by the majority of owners, plastic steel doors have a good sound insulation effect, for everyone to create a more healthy and quiet living environment.
What are the advantages of steel doors?
Just now we learned about the history of the development of steel doors. Let's take a look at the material of steel doors. It is based on polyvinyl chloride, modified PVC, resin and other major raw materials, according to certain design requirements, in accordance with national standards, in the profile cavity filled with lining steel (lining steel generally used 1.5mm galvanized cold-rolled steel) , with a special machine for cutting, welding, installation. So it has irreplaceable properties of other materials and it has the following advantages over other materials' doors:
(1) Its materials are fire-extinguishing, not self-igniting, non-combusting, and self-extinguishing;
(2) Its thermal conductivity is much lower than wood and metal; the heat insulation effect is much better than aluminum.
(3) It is between -30°C and -70°C. It is not deformed, discolored or brittle in the hot sun, heavy rain, dry and humid environment. It is also resistant to acid and alkali chemicals and the erosion of waste gas. Dust, cement, adhesives.
(4) The well-designed door structure of the plastic steel door is equipped with a drainage groove. The joints are tight, and the rainwater can be completely isolated. The sound insulation is less than 20 UP.
(5) Plastic steel doors are not only easy to clean, but also have a long service life. As long as the use of cleaning agents after the bright as new, it can generally reach a service life of more than 30 years.
What are the advantages of steel doors?
We know that cooking areas and toilets are relatively humid and dirty places. The doors used in these places must be fireproof, heat-insulating, waterproof, moisture-proof and easy to clean. Because the steel doors have the above advantages, they are widely used as kitchens. Door and toilet doors.
The above is the small series about steel doors and steel doors what are the advantages of sharing, to everyone to be a reference! If you have more questions, you are welcome to continue to pay attention to Qijia Information. We will offer more exciting content in the later period.
