Steel Grit Applications
To the steel structure , the speed of corrosion is mainly related to the relative humidity of the air and the composition and quantity of pollutant in the atmosphere. In order to extend its service life,the steel structure must need surface treatment,then by spraying to form the protective film on metal surface to prevent and reduce metal corrosion.
Harbor wharf construction uses the steel structure massively.Therefore, the steel structure anti-corrosion request is unusual high.The harbor machinery is frequently confront with some special environment .For example ,the moist maritime air environment ,which cause the steel structure constructions get deep corrosion.In that case,the corresponding sand blasting and coating are needed to protect the harbor machinery.
