The East Rand towns grew around the gold mines and factories of the last century. Germiston, Boksburg, Benoni, Brakpan, Springs, Alberton and Kempton Park are full of family homes built from the 1950s to the 1980s, and most of those homes had steel windows. Replacing them is the most common reason people search for aluminium windows East Rand suppliers make. Coetz™ makes aluminium windows to order at Laser Park in Johannesburg, prices every one online and delivers across Ekurhuleni. Every window is made in 1–2 days and glazed with 6.38 mm clear laminated safety glass.
Coetz™ supplies only. Your builder or a window installer fits the windows (see aluminium window installers).

Aluminium windows East Rand: matching the old steel layout
Old steel windows on the East Rand are often wide, multi-pane units, with fixed panes and a small opening vent at the top or side. To keep the look of the house, match that layout:
- Twin openers with a 600 mm vent come closest to the classic steel layout for bedrooms.
- 4-pane top hung windows divide a wide opening into four panes, for living rooms.
- Single openers suit kitchens and bathrooms.
Each product page has a drawing, viewed from inside, that shows exactly which panes open.

Replacing steel windows step by step
- Measure the opening once the old frame is out. Steel frames are often built into the brickwork, so the opening can only be measured accurately after removal. Order the next standard size that fits; our units are made 10 mm smaller than the catalogue size (see how to measure aluminium windows).
- Plan the plaster repairs. Removing a built-in steel frame usually damages the reveal, so your builder will make good around the new frame.
- Check the burglar bars. Many East Rand homes have bars fixed in the reveal. A top hung window opens outwards, so it clears bars fitted on the inside.
- Seal it properly. A continuous bead of exterior sealant between frame and wall keeps storms out (see how to install aluminium windows).
More detail is in replace steel windows with aluminium.
Newer homes: Bedfordview, Edenvale and the Benoni estates
Not all of the East Rand is older housing. Bedfordview and Edenvale have larger homes, and Benoni and Boksburg have newer lake and golf estates. There, estate guidelines usually set the frame colour (often Charcoal or Black), and new windows need HOA approval before you order.
