Expansive material and finish options help models resist peeling, heat and corrosion.
China manufacturers are strengthening their aluminum extrusion selections by offering a wide range of surface treatments that make alloys withstand rust, water, high temperature or alkali.
Among the top finishing techniques that protect aluminum extrusions from corrosion are anodization, painting and powder coating. These also prevent peeling and discoloration of the products over time. Some products are subjected to thermal breaking for good temperature conduction. Protective strips such as heat insulation and rubber strips are present in a few products.
The latest aluminum extrusions can be used as heat sinks, industrial equipment and automotive parts, decoration and door and window profiles. A number of suppliers are welcoming buyer-specified sizes, colors and finishes.
The products in this gallery represent current trends in aluminum extrusions.
