Local context

Working in Grabouw Industrial

We service Grabouw Industrial and the surrounding blocks of Grabouw Industrial, Grabouw, with access off the N2 and R321. Mediterranean summers with strong south-easters carry dust and salt onto condenser coils, and winter rain drives condensation risk at dock openings.
