Supply-Only Aluminium Windows South Africa

Supply only aluminium windows — here is what South African buyers need to know, with supply, installation and service from Coetz Glazing.

Coetz™ is a specialist supply-only manufacturer: we build your aluminium windows and doors to order in Johannesburg, price every standard size online, and deliver nationally — you or your installer handle the fitting, and you keep the installer margin.

How supply-only works

Supply-only means you buy the manufactured windows directly at catalogue prices, without paying for bundled installation you may not want. It suits owner-builders, contractors managing their own teams, renovators with a trusted installer, and projects outside major centres where local fitment is cheaper. Installation guides are published on the site, and every product drawing shows the unit viewed from the inside so ordering the correct handing is straightforward.

National delivery

Every item is manufactured to order and supplied ready for collection from our Laser Park, Roodepoort premises or delivered — Johannesburg (1–3 working days from dispatch), Gauteng (2–5) and national (3–7), with the exact rate calculated automatically at checkout. All catalogue prices exclude VAT.

National deliveries run 3–7 working days from dispatch. For very large or fragile national consignments our team confirms packaging and transport in writing before dispatch.

Why aluminium is the right choice

For supply only aluminium windows, aluminium is the material that lasts. It will not rust, warp or rot, it shrugs off the South African sun, and it needs almost no maintenance beyond an occasional wipe-down.

Our frames are powder-coated in any colour, from crisp white and charcoal to bronze and natural anodised finishes, so the windows match the architecture instead of fighting it. Slim sightlines let in more glass and more daylight.

Every unit is glazed with 6.38mm laminated safety glass as standard, which improves security, cuts outside noise and holds together if it is ever broken. Double glazing and performance glass are available where thermal comfort matters.
