Iron guardrail and ordinary railings compared, the height is relatively high, so the material required is stronger, and thus stronger solidity. Most of the iron guardrail is installed in the open environment, easy to be corroded by rain. So the choice of raw materials can choose galvanized steel, and surface treatment can choose anti-corrosion than even good spray powder baking paint, fluorocarbon paint, and the choice of spray paint is required for primer and top coat processing, so as to achieve better anti-corrosion and anti-rust effect, the color of the surface paint treatment is usually black as the main color, the surface color can also be processed according to the corresponding needs.

The advantages of aluminum alloy railing: aluminum alloy railing is light weight, strong corrosion resistance, longitudinal elongation up to 10 meters or more. The appearance of aluminum profile has bright, matte, its treatment process using anodic oxidation treatment, iron art of a variety of art forms, surface treatment oxide film to 0.12m/m thickness. Aluminum alloy railing connection is usually riveted, but also aluminum welding.

Stainless steel glass railing advantages: stainless steel railing beautiful appearance, corrosion resistance, stainless steel railing style can be assembled with a variety of stainless steel profiles welded, welded points polished smooth for polishing treatment, the surface treatment usually sanding and mirror light two ways. Stainless steel railing columns and handrails can also be made of stainless steel profiles, and then with glass to do the railing, so that this railing is more noble, transparent.
