We had burglar bars fitted by Penuel and Vumalani and these guys were brilliant. They worked so efficiently and cleaned up along the way. I am very impressed with the two of them. Great workmanship.

We are very satisfied with the laser-cut security gate and its installation. The design and planning, done by Alex and his team, was very professional. Their Yellow installation team, consisting of Bheki and Gustav, was very friendly, willing to listen, and have great craftsmanship. Please contact Robo Door if you are in need of security gates.

How we count: RoboERP orders placed in the 24 months to 9 September 2026, the same window as our city pages, matched on the delivery address on the customer record. An order counts for a province when its address names the province or one of the towns listed under it on this site. Cancelled orders are left out. Product units come from the invoices of completed orders. The province figures include the city figures, and 38 addresses name places in two provinces, so the totals on this site overlap. Do not add them together.
