We design, build and install premium aluminium sliding, swing, cantilever and telescopic gates across Auckland — engineered to last, automated to perform.
What we do
From a discreet pedestrian gate to a 6-metre cantilever sliding system, we handle the full job — design, fabrication oversight, automation and install.
All servicesTrack-mounted and cantilevered sliding gates engineered for long, smooth runs across wide driveways.
Single or double-leaf swing gates with concealed underground or articulated arm motors.
Multi-panel telescopic systems that cover wide openings where space is tight.
Custom horizontal slat and vertical bar designs in powder-coated aluminium — plus security screens and mesh panels.
Keypads, remotes, intercoms, GSM and smartphone control. We retrofit existing gates too.

Built locally in High grade aluminium and finished in a premium powder coat in your selected colour and finish.
Clean installation, commissioning of automation, and a walk-through so you know how everything works.
