Architectural Aluminium Trellis Security Doors in Northcliff

Properties across Northcliff—from established family homes in Honeydew and Cresta to Parkhurst and Pimville—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 Northcliff 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 Northcliff or building a new commercial development, folds away compactly is at the heart of every installation. The expandable lattice design stacks tightly against side walls, keeping doorways wide, open, and easy to walk through. 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.
