Trellis door vs hinged burglar door vs sliding security gate
How to choose between a retractable trellis door, a hinged burglar door and a rigid sliding security gate, by opening width, daily use, stacking space, locking and warranty.

Western Cape buyers choose aluminium trellis doors. Of the 86 trellis doors on Western Cape orders in the 24 months to 9 September 2026, 79 were Alu-Deluxe. RoboERP holds 92 orders with a Western Cape address in that time, and 75 are marked installed. A trellis door starts from R3,500 and burglar bars from R1,000.
In the Western Cape our Alrode installation team measures and fits. Your trellis door or burglar bars are made in our Alrode factory. The province also has 14 public Robo Door locations, from Vredenburg on the West Coast to Knysna on the Garden Route.
The Mossel Bay location also serves George.
My security doors were installed 6 months ago. I experienced problems with the locks, and after reporting it, their technical team arrived within hours to repair. Great service.

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.
