"1. Corrosion resistance: A hard aluminum oxide film is tightly attached to the surface of the aluminum alloy railing, and its protective performance can be further enhanced by surface treatment, so it has strong corrosion resistance, so it can be used safely in areas with air pollution or bad climate, and can solve the worries of maintenance for you.2. Lightweight: Its weight is much lighter than that of iron, steel and copper, but its hardness is not inferior. Lightweight aluminum alloy railings are not only low-carbon, environmentally friendly, easy to handle, but also cheaper to transport. It is now a popular commercial building material.3. Hardness: The hardness of aluminum alloy railings can resist tensile force and large impact force, and its resistance is better than other traditional building materials.4. Exquisite and smooth surface: aluminum, with unique advantages, can be applied to many different surface polishing technologies, such as paint, powder coating, anodic oxidation and electrophoresis. The powder coating with the smoothest surface can resist ultraviolet light, and can keep bright luster for a long time without frequent maintenance, so the powder coating is durable. "
