How about plastic steel doors?
Plastic steel doors are not new products. They were on the market in the 1950s. At first, the plastic steel door was a simple and rough single-cavity structure. With the worldwide energy crisis of 1972, plastic steel doors and windows with better energy-saving effect were widely used in the early 1970s. At present, plastic-steel doors have been recognized by consumers all over the world, and they are popular because of their perfection. In Asia, South Korea, Taiwan Province Province, Singapore and Thailand use steel doors and windows.

Let's take a look at the development of plastic steel doors in China. Domestic plastic-steel doors started late and began to be produced in the 1970s, but the technology really matured when 1983 introduced advanced equipment. At present, there are more than 2,000 profile extrusion production lines, more than 400 profile factories and more than 3,000 assembly plants in China. 1999 The profile production capacity is 800,000 tons, and the annual assembly capacity of doors and windows is 60 million square meters. Now it has become one of the few fast-growing industries in China. At present, plastic steel doors have been accepted by the majority of owners. Plastic steel doors have good sound insulation effect, creating a healthier and quieter living environment for everyone.
What are the advantages of plastic steel doors?
We have just learned about the development history of plastic steel doors. Now let's look at the material of plastic steel door. It is made of PVC, modified PVC, resin and other main raw materials. According to certain design requirements and relevant national standards, the profile cavity is filled with lining steel (lining steel is generally 1.5mm galvanized cold-rolled steel), which is cut, welded and installed by a special machine. Therefore, it has irreplaceable properties of other materials. Compared with doors made of other materials, it has the following advantages:
(1) Its material is fire-proof, non-spontaneous combustion, non-combustion supporting and self-extinguishing;
(2) Its thermal conductivity is much lower than that of wood and metal; The heat insulation effect is much better than that of aluminum.
(3) It is not deformed, discolored and fragile in the scorching sun, rainstorm, dry and humid environment at -30℃ to -70℃, and it is also resistant to the corrosion of acid and alkali drugs and waste gas salts, and is not affected by dust, cement and adhesive.
(4) The well-designed door structure of the plastic-steel door is equipped with a drainage trough, and the joints are tight, which can completely isolate the rain and 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 detergent is as bright as new after cleaning, its service life can generally reach more than 30 years.
What are the advantages of plastic steel doors?
We know that cooking areas and toilets are wet and dirty places, and the doors used in these places should be fireproof, heat-insulating, waterproof, moisture-proof and easy to clean. Because of the above advantages, plastic steel doors are widely used as kitchen doors and bathroom door.
