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.

The powder coated surface should be delicate, full, transparent, strong in three-dimensional sense, and can maintain relative luster for a long time. The decorative surface coating is at least 40um. The poor appearance is dim, the stereoscopic effect is poor, and after a period of time, there is light loss, powdering, paint stripping, etc. Slight orange peel on the surface of powder coated profiles is accepted. There are almost no orange peels on high-quality powder coated profiles, but the orange peel on the surface of poor powder coated profiles is obvious and serious. The reason is the use of poor quality powder coatings, or the production process and production management are not strict.

After special finishing operations, you may cut the profiles into shorter lengths depending on the actual dimensions of the windows and doors. While at it, you may use special devices to clamp the profiles, cut and transfer them to a conveyor.
