Architectural Aluminium Trellis Security Doors in Greenstone Hill

Properties across Greenstone Hill—from established family homes in Wattville and Dunvegan to Aston Manor and Lakefield—face Gauteng's demanding Highveld climate. Freezing winter night drops, intense summer UV glare, and severe hailstorms place heavy stress on legacy fenestration and building hardware.

Our Greenstone Hill aluminium trellis security doors are manufactured from Heavy-duty architectural aluminium alloy (6063-T6), protected by a Qualicoat marine-grade finish (60–80 microns thick). This guarantees the frames will never warp, rust, swell, or peel under intense sunlight or driving rain, while precision weather seals keep winter draughts and storm water out.

Whether you are renovating a home in Greenstone Hill or building a new commercial development, whisper-quiet smooth operation is at the heart of every installation. Sealed top-hung bearing rollers allow even wide double-leaf patio gates to slide open and shut effortlessly with one hand. All work is carried out in full compliance with national building standards (Tested for high lateral force resistance, crowbar leverage, and impact protection), from the first on-site measurement to final sign-off, including the removal of old frames.
