Measure Your Aluminium Windows and Doors with Confidence
Our step-by-step guide shows exactly how to measure width and height for an accurate order.
Buying aluminium windows and doors direct means no middleman markup: we manufacture your aluminium windows and doors to your exact opening sizes and ship them to site. Because every unit is made to order, you are not paying for stock sizes that almost fit. Browse the full range of aluminium windows and doors above, or send us your sizes for a same-week price.
Automatic Doors, Supplied and Serviced
Coetz™ is not only aluminium windows and doors. We also supply, install and service automatic door systems for shopfronts, clinics, offices, retail stores and industrial buildings – the same engineering standards we apply to our aluminium windows and doors, applied to entrances that open thousands of times a week.
- Automatic sliding doors – the standard choice for shopfronts and main entrances, with sensors, safety beams and a manual break-out option.
- Automatic swing doors – operators fitted to new or existing hinged doors, common in clinics, offices and accessible entrances.
- Automatic revolving doors – for high-traffic entrances where keeping heated or cooled air inside matters.
Automatic doors are an installed and maintained service, unlike our supply-only aluminium windows and doors: we survey the opening, fit the operator and can keep it serviced afterwards. We work nationwide, with dedicated teams in Pretoria, Cape Town, Durban and Sandton.
Whether you need automatic entrances or standard aluminium windows and doors, the glazing behind them follows the same rules – see the South African Bureau of Standards for the national glazing code, or our own glazing compliance centre.
Aluminium Windows and Doors FAQ
Do you install the windows and doors?

What if my opening isn’t a standard size?
WhatsApp or contact us and we’ll advise on the closest standard size or custom options.
Can I collect instead of paying for delivery?
