Architectural Aluminium Trellis Security Doors in Glen Marais

Properties across Glen Marais—from established family homes in Katlehong and Aston Manor to Sunward Park and New Redruth—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 Glen Marais 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 Glen Marais or building a new commercial development, instant slam-lock protection is at the heart of every installation. Equipped with rapid-locking slam locks that lock automatically when pushed shut, giving you instant protection during an emergency. 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.
