The aluminum alloy profile has been treated by various processes, and its surface has the characteristics of acid resistance, alkali resistance, air pollution resistance, acid rain resistance, ozone resistance, ultraviolet resistance, etc. It can maintain the inherent color and luster for a long time.
The process of manufacturing aluminium window profiles involves several steps, from raw material selection to final product testing. Here is an overview of the typical process:
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.
In addition to building facades, cast iron elements are also used in furniture design. From elegant garden benches to intricate bed frames, these elements add a touch of elegance to any room. The durability of cast iron furniture makes it a popular choice for outdoor use, as it can withstand the elements and retain its beauty for years to come.

As such, it makes the material hardy and thus can withstand different harsh environmental and mechanical conditions.
Because castings may be created to generate final products with complicated designs or with aesthetically basic techniques, cast iron is an excellent option for constructing a fence that is both affordable and visually appealing.
In the current market, the majority of cast iron decorative fence is produced by a few big producers who mainly offer welding sloops. These manufacturers account for the majority of the market share.
- Material Choose between plastic or metal depending on the door's location and weight. For exterior doors exposed to the elements, metal wheels may provide better longevity.
Before choosing, make sure that the chose aluminum profile is compliant with local building codes and standards, especially with certain standard qualifications for quality standards, energy efficiency and safety.
