First, avoid bumps. This is the first point to pay attention to iron products, iron products in the handling process should be carefully handled; The place where the wrought iron products are placed should be a place where hard objects are not often encountered; The ground where the wrought iron products are placed should also be kept flat, and the wrought iron guardrail should be firmly installed. If it is unstable, the wrought iron guardrail will be deformed over time, affecting the service life of the wrought iron guardrail.

Second, dust regularly. Outdoor dust flying, accumulated over time, iron facilities will fall on a layer of floating dust. It will affect the color of the iron, and then lead to the damage of the iron protective film. Therefore, outdoor iron facilities should be wiped regularly, generally wiped with soft cotton fabric.

Third, pay attention to moisture. If it is just the general outdoor air humidity, you can rest assured that the rust resistance of the wrought iron guardrail. If it is foggy, use dry cotton cloth to wipe the water on the iron; If it rains, you should dry the water immediately after the rain stops. Because of the acid rain raging in most areas of our country, the rain that remains on the iron should be dried immediately after the rain.

Fourth, away from acid and alkali acid and alkali is the "number one killer" of iron guardrail. If the iron guardrail is accidentally stained with acid (such as sulfuric acid, vinegar), alkali (such as methylalkali, soapy water, soda water), it should be immediately washed with clean water, and then dry with dry cotton cloth.

Fifth. Remove rust if the iron guardrail is rusty, do not take it upon yourself to sand it. If the rust is small and shallow, cotton can be dipped in oil and applied to the rust. After a while, wipe with a cloth to eliminate the rust. If the rust has expanded and become heavy, the relevant technicians should be asked to repair it.
