Different types of galvanized types have different properties and characteristics. We must pay attention to the use characteristics of mobile scaffold accessories using different galvanized materials to ensure the service life and quality of the scaffold accessories.
The main galvanized types of portal mobile scaffolding accessories in the Chinese market today can be divided into hot-dip galvanizing, overall cold galvanizing, split cold galvanizing, and anti-rust paint treatment. Different galvanizing methods need to pay attention to different matters, the processing technology will also be different, the service life will also have certain changes.
1. The service life of hot-dip galvanized mobile scaffolding accessories is about 10 years, the surface does not need maintenance, and there is no restriction in use. However, the cost is high and the raw materials that need to be used are more complicated. In actual use, many mobile scaffolding accessories are not easy to use or even eliminated due to deformation and other reasons. Therefore, the overall service life is about 5 years. Therefore, pay attention to maintenance when using mobile scaffolding accessories, so that its service life will be more, and the value in use will be more perfect.
The service life of the integral cold galvanized mobile scaffolding accessories is about 5 years, the surface does not need to be maintained, and the cost is moderate. The main processing technology is: welding the scaffolding accessories and then galvanizing, every part of the surface is galvanized. The 5-year surface treatment period is very close to the use-out period, and it has a relatively large market share.
2. The surface treatment process of the split cold galvanized mobile scaffold accessories is: first galvanize the raw material of the pipe, and then weld, the weld joint is treated with silver powder anti-rust paint, and the weld joint and its surroundings are easy to rust. The cost of galvanizing is about 400 yuan-500 yuan lower than the overall cold galvanizing. In this process, in welding, because the pipe is galvanized, the welding firmness is greatly reduced. The market share is very small.
3. The process of anti-rust paint mobile scaffolding accessories is mainly divided into two types: paint-invading scaffolding and anti-rust paint spraying. Paint-invading scaffolding is to put the scaffold in the paint pool and then take it out to dry. Spraying scaffolding is treated with anti-rust paint on the surface by spraying. Anti-rust paint scaffolding requires 1-2 years of surface anti-rust paint maintenance, but the production cost is relatively low.
