Omega Windows & Doors
We have total control of the casting process, which is important for ensuring consistency in the quality of aluminium logs we produce for extrusion.
By using recycled aluminium scrap from our own manufacturing process and scrap sourced from other New Zealand extruders, we are doing our bit to protect the environment.
The energy consumed to make extrusion from recycled aluminium is 10 times less than the energy required to make an equivalent amount of extrusion from virgin aluminium sourced from the aluminium smelters.
The chemical composition of our extrusion logs and billet are closely monitored before and during each cast using a state-of-the-art Optical Emission Spectrometer, with standards tighter than those required by AS/NZS1866.
We also use a modern Tensile Testing machine to evaluate material strength, ensuring we comply with all mechanical property standards outlined in AS/NZS1866.
