Description

technical field [0001] The invention relates to the technical field of guardrail processing and production, in particular to a method for painting the surface of a metal guardrail. Background technique [0002] Guardrails are mainly used for the protection and protection of personal safety and equipment and facilities in residences, highways, commercial areas, public places and other occasions. Guardrails can be seen everywhere in our lives. [0003] Guardrails are usually made of steel, such as: stainless steel, round steel pipe, square steel pipe or profiled steel plate, iron wire. Surface treatment process: automatic electrostatic powder spraying (that is, plastic spraying) or painting. In recent years, plug-in and assembled guardrails made of aluminum alloy have become more popular. [0004] The columns of the guardrail are fixed to the ground by expansion bolts. It is usually installed on both sides of the logistics channel, around the production equipment, in the c...
