In various fields of human activity aluminum profile is used. It is used in construction, furniture production, mechanical engineering, the construction of all kinds of structures and other areas. The aluminum profile is used for the manufacture of window and door structures, decorative elements, finishing of building facades.
If earlier wood or plastic was used predominantly for the manufacture of doors, today aluminum profiles have also firmly entered this area. It is especially used in modern interiors as it has an attractive silver color.
The material is highly valued in design and architecture due to its physical and chemical characteristics and technical and operational qualities. This metal has a relatively low weight, is resistant to corrosion, environmentally friendly, durable (service life is at least 80 years). Structures and components made of aluminum are resistant to external aggressive atmospheric influences. Temperature jumps, precipitation and high humidity are absolutely not terrible for this material.
Key advantages of aluminum profile:
• lightness;
• hardness;
• strength;
• resistance to corrosion;
• plasticity;
• low magnetic properties.
The profile is made not of pure aluminum, but of special alloys, which significantly increase the various characteristics of products. Based on the specific type of alloy and metalworking technologies, the finished product can have different properties. Certain of the above qualities can be more or less expressed. The alloy may contain different elements - copper, manganese, magnesium, silicon and others. Thanks to this, it is possible to significantly improve the natural qualities of the metal.
However, he also has certain disadvantages that may be important in one case or another. Aluminum enters into chemical reactions with other metals. It is a metal with high thermal conductivity, which also somewhat narrows the scope of its use. Although modern technologies allow us to fight these shortcomings.
In the production of window and door structures, two types of aluminum profiles are used today:
• Warm. It has a reduced thermal conductivity, is equipped with a special insert that allows you to minimize heat loss through the metal itself. Entrance doors are often made from this profile. The design provides for internal and external contours, between which there is a thermal insert.
• Cold. It does not have a thermal insulation insert, has a high
