As with all Redrock Products, the Redrock vacuum tanker range is built to the highest quality. Rolled from 6mm steel, all the tanks are welded both internally and externally and include 4" x 2" channel rings welded inside the tank for extra strength and a longer service life. The Redrock body, wheel arches, supports and drawbar are designed and manufactured to the most exacting standards to maintain rigidity, reliability, and road worthiness year after year.
