Depending on the aspect of their application, their cross-sectional shapes can vary. Generally speaking there are four main cross-sectional shapes of fixed window profiles: flat, round, unequal polygon and equal polygon. Among them, the plane type is commonly used in door frames, wall corner lines, etc.; round profiles are mainly used for aluminum alloy pipes; unequal polygons and equal polygons are commonly used for window frames, partitions, etc.

They offer optimal strength, durability, and precision, with standard dimensional tolerances of +/- 0.15 mm, customizable upon request.
- Lubricate the Wheels Applying a suitable lubricant, such as silicone spray, can reduce friction and improve the wheels' performance. Avoid oil-based lubricants, as they can attract more dirt.
Moreover, aluminium profiles can be customized to incorporate thermal breaks, which enhance energy efficiency by reducing heat transfer between the interior and exterior of a building. This feature helps in maintaining comfortable indoor temperatures and reducing energy consumption for heating and cooling.
The general public’s picture of wrought iron is of a blacksmith hammering wrought iron on an anvil with a coal forge in the background. Small irregularities are part of the charm and value since wrought ironwork is forged by hand. Artistic patterns and curves are the evidence of the smith’s hammer in true wrought iron.
However, the art of wrought ironworking is not without its challenges. The process requires immense skill and precision, as well as access to specialized tools and high heat sources. As modern manufacturing techniques have evolved, the demand for hand-forged wrought iron has decreased, leading to a decline in traditional blacksmithing. Nevertheless, the allure of wrought iron remains, and many artisans continue to preserve this dying craft.
