Most of these features, which used to be unique to iron, are now available in steel, which is by a large margin the superior material. And visually, the only difference between the two is the texture. Steel is smooth, while iron has a visible grain, whether it is produced by casting, or by pulling. This grain is actually caused by impurities in the iron and is what accounts for its unreliable nature. These impurities cause weak points in the iron that can lead to breakage when it’s put under stress. Steel’s smooth appearance results from the fact that these impurities have been burned out, or, in the case of carbon, evenly distributed throughout the material. When you think of the medieval blacksmith hammering away, what he is doing is distributing the carbon evenly to turn iron into steel.

Aluminum profiles are metal materials. Aluminum add various metal elements to make various alloys, which have advantages that other alloy profiles cannot match. Aluminum alloys has light weight and high strength, and can be extruded into a variety of complex cross-section profiles meeting the requirements of door and window design for various new sections.

If properly sealed, chromic acid anodize affords the aluminum equivalent to corrosion protection to the relatively thick sulfuric and Hardcoat type anodize.

You’ll always find them in various surface finishing, but the ideal one is dependent on your preference.

Aluminum is the best aluminum profiles door & window and deep processing supplier. 
1. We use high quality thermally broken raw materials as insulation bars. By adding an insulation bar to aluminum profiles, we form an insulation barrier to prevent heat transfer from outside and inside. The material of the insulation bar is PA66 nylon, which has good toughness and strength. Therefore, it has a good insulation effect.
2. A wide variety of finish options are available for your different coating requirements. Powder coating, anodizing and wood grain finishes are the most popular choices for extruded aluminum door & window frames.
Established over 11 years ago, our company has been one of China's best aluminum profile suppliers. And since 2011, when we started exporting our products, we have become one of the best suppliers in the world.

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.
