About OSG
Engineered aluminum. Owned end to end.
We are a small, focused team of engineers, fabricators and installers. We measure it, we design it, we cut it, we fit it — one accountable partner for the entire aluminum window envelope.
Craft
Precision from the first millimetre.
We rely on 3D laser scanning and CAD-driven CNC fabrication so every profile lands within a 0.5mm tolerance of the drawings. Every detail — thermal breaks, drainage channels, hardware alignment — is finished by hand.
Values
One team from measure to install.
We don't hand off between fabrication and installation. The team that measures your opening is the team that ships and fits the finished unit — nothing gets lost in translation.
