2. Load-bearing requirements
For applications with certain structural strength requirements, such as large doors and windows. It is better to choose the profile with higher tensile strength, such as: 6063-T6.
However, these efforts serve to preserve not just the material but also the artistry and history it represents. Over time, the character it acquires transforms your property into something akin to a local treasure.
Ordinarily, aluminum profiles for windows and doors are available in both standard and customized sizes. You can choose either one depending on the needs of your project.


The window profile, or window frame, can be made mainly from three different materials: plastic, i.e. PVC, wood and aluminium. Plastic profiles are the most common and the most economical. Laminated timber frames are valued for their naturalness and rigidity, which is particularly important for larger patio windows. However, they are more expensive, heavier and require regular maintenance. Aluminium profiles, on the other hand, although they have the highest cost, are the most rigid, durable and maintenance-free. This is why their share of the market is steadily increasing, although due primarily to their high price, they still do not exceed a few percent.
When normal glass is broken, the edge is sharp and easy to cause damage to the human body. After the tempered glass is broken, the edge is smoother and less harmful to the human body. In the door and window industry, ordinary glass is gradually being eliminated, and tempered glass is becoming more and more popular. High-quality tempered glass has less impurities, no blistering, and smooth surface. It is safer in daily use of aluminium windows and doors.
