Renza Projects is a marketing business for security trellis, doors and windows and we are based in Pretoria East. We also market and do free quotations on doublesided precast walls and light weight concrete panels to enclose lapas, renovate wooden houses and sheds. Our trellis are manufactured and installed by TrellisSOS.

What is Renza Projects all about?


Resources and expertise combined.


With his back ground in hardware and building material, Francois Duminy chose a few products and projects to get involved with. Security trellis by TrellisSOS is the main product.
Retractable and expandable security trellis are manufactured from strong and high quality steel to secure your house, town house, flat,office or bush retreat. Good and neat enough for embassies, offices, sport bars, cafe's, Liquor stores, jewelry or any other shops that needs security trellis in front of their display windows. Our fixtures on windows and other strategic openings are designed to compliment  our security trellis, doors and gates.
Products from TrellisSOS are accepted by most security and insurance companies.
Besides TrellisSOS Renza projects was also involved with the building and erecting of Tinyhouses and the upgrading or restoration of wendy and wooden houses with our lighter weight precast panels.
In order to assist the DIY precast panel-builders we complied a manual on how it's done, based on our previous experience. Brick-crete, wood-crete and stone-crete panels can be bought directly from us.
