澳大利亚采购需求：铝合金门窗制造商

Hi there, I'm exploring options for aluminium windows for a residential renovation project. I need a quote on the following: 4 sliding windows (1800 x 1200mm), 4 awning windows (1200 x 900mm), 2 fixed windows (1500 x 1800mm), and 2 sliding doors (2100 x 2400mm). Would love to know about available frame colors, pricing for supply only vs. supply + install, and expected lead times. Also curious about warranty details, whether Low-E glass is advised, and if you have brochures or spec sheets to share. Sizes are approximate, so adjustments might be needed later. Thanks!
