The airport project

In order to adapt to the reform of modern airport logistics, it is convenient to store air cargo. The airport shall set up special areas and adopt the whole non-power conveying platform to accelerate the speed of airport logistics conveying and facilitate the turnover of goods. Due to the particularity of the local climate in Australia, the outdoor humid and salty air environment, the whole equipment on the material requirements are particularly high. Solution: in order to adapt to Australia's humid and salty air environment, the steel structure of the entire transmission line is required to reach an average of 85um hot dip galvanizing. The fasteners are hot-dip galvanized with precision M8. The roller is made of 316L material. For hot dip galvanized products, we use a thickness gauge to measure. The roller adopts 316L for salt spray test for more than 48 hours.
