The aluminum entrance door anti-theft fence is a widely used road traffic facility at present. When impacted by external forces, the fence can effectively absorb the collision force and reduce the damage to vehicles and pedestrians when an accident occurs. There are vehicles passing on the urban traffic roads day and night. Therefore, the aluminum entrance door anti-theft fence is needed to guard the passing vehicles all the time. Exposed to wind, sun and rain all year round, the guardrail made of metal will rust. To delay the occurrence of rusting of guardrails, it is necessary to carry out anti-corrosion and anti-rust treatment on their surfaces, which can be treated with powder coating or hot-dip galvanizing.

If the corrosion resistance of the aluminum entrance door anti-theft fence is not good enough and the quality is not up to standard, even the fence that has not been in use for a long time will have problems such as cracking and rusting. It will look very old and unattractive, affecting the visual effect of the entire highway. The view that if the performance of the aluminum entrance door anti-theft fence improves, does it not require maintenance? Such a view is wrong. Even the aluminum entrance door anti-theft fence with the best material still requires our daily maintenance.

Once the aluminum entrance door anti-theft fence is exposed to the sun and wind for a long time, its color will be much worse than before. This reflects the importance of fence maintenance. In comparison, the anti-corrosion performance of powder-coated guardrails is much stronger than that of ordinary guardrails. The guardrail manufacturers produce this strong corrosion resistance based on the heavy anti-corrosion treatment in their production process, which solves the problem of rust and breakage that traditional ordinary guardrails are prone to. The surface of this guardrail is sprayed with full polyester powder, and the internal coating is treated with hot-dip galvanizing. Under such a structure, The guardrail is connected to the substrate through electrostatic spraying, which endows it with extremely excellent anti-corrosion properties.
