For maximum protection vacuum tankers can be hot dipped in a galvanise bath to provide an anti-corrosion coating both inside and out. The hot-dip galvanization happens at a temperature of 450°C. During this process, the steel is covered with three coatings made of a mix of steel and zinc, as well as with an outer coating of pure zinc. The quality of workmanship in HiSpec slurry tanks together with the galvanisation guarantees an efficient protection.

Note: Capacities of 4000 gallons & upwards may require altered dimensions to accommodate the galvanising process.
