Which door and window material is better, plastic steel or aluminum alloy? There is no problem in using this kind of product for 30 years. Too many people buy the wrong one.

When I was at work today, a fan commented on the thread and asked: Which one has the longest life, plastic steel or aluminum alloy? I was still a little confused at the time. I had not paid attention to this kind of problem before, so I hurriedly checked it out and studied it to improve my professional knowledge. Today I will tell you about the two materials and which one has a longer lifespan. .

1. Recognize the two materials

1. Plastic steel: the raw material is polyvinyl chloride (PVC) resin, then press It is formed by adding stabilizers, colorants, fillers, UV absorbers, etc. in proportion. Commonly used in windows, doors and other home decoration.

Features: strong rigidity, corrosion resistance, good toughness, sound insulation, good thermal insulation and durability.

Identification method: Identify from the appearance. The size is uniform, the color looks soft, and the wall thickness of the extended part is about 2 mm. In addition, you also need to check the security code (the genuine security code is usually a dotted 20-digit Arabic numeral)

2. Aluminum alloy: It is a non-ferrous metal material. Aluminum is used as an element, and alloying elements are added to form an aluminum alloy after heat treatment. Wide range of applications (aerospace, automobiles, ships, machinery, etc.)

Features: low density, high strength, corrosion resistance.

Types: deformed aluminum alloy (can withstand pressure processing, often used in aviation equipment and building doors and windows) and cast aluminum alloy.

2. Comparison of the two lifespans (taking house windows as an example)

Plastic steel windows: Generally speaking, plastic steel windows The lifespan is about 20 years. The lifespan of plastic steel windows made of PVC is about 30 years. Because windows are exposed to wind and rain all year round, they will fade and deform. The influence of external factors greatly reduces the life of plastic steel windows. If the plastic steel process is below the national standard, the life span is 5 to 10 years, and if it is above the national standard, the life span is 15 to 20 years.

Aluminum alloy windows: generally around 50 years (aluminum alloy has the characteristics of aging resistance and long service life) . So needless to say, everyone knows who lives longer. So in terms of lifespan: plastic steel is shorter than aluminum alloy.
