Robust, durable, accurate
RDA stands for Robust, Durable, Accurate. RDA Aluminium supplies, installs and repairs aluminium doors and windows in Cape Town. The business is based in Blackheath, and several installation teams work across the city, on houses, new builds, shops and offices.
The three words describe what an aluminium installation should be once the installers have packed up: frames fixed solidly, a finish that lasts, and doors and windows that are square, sealed and run the way they should.
