Aluminium Sliding Doors Randburg

In older Randburg homes in Linden, Northcliff, Blairgowrie and Fontainebleau, the garden door is often a pair of steel French doors that swing into the room and have rusted at the bottom. The most common job behind aluminium sliding doors Randburg orders is replacing those French doors with a sliding door that fits the same opening and doesn’t swing. Coetz™ makes every door to order at Laser Park, close to Randburg, in 1–2 days with 6.38 mm clear laminated safety glass. The exceptions are our Patio sliding doors and a few large Elite sliding door sizes, which use toughened safety glass. This page covers the swap from French doors, choosing a threshold for an easy step-through, and real prices.

Coetz™ supplies only. Your builder or a door installer fits the doors.

Aluminium sliding doors Randburg: replacing French doors

Old French door openings are usually between 1 200 and 1 800 mm wide. A two-panel sliding door fits the same opening:

• No swing space. Furniture can go right up to the door, which matters in a smaller lounge or dining room.
• Same opening, no structural work. Measure the opening once the old frame is out and order the next standard size. Our doors are made 10 mm smaller than the catalogue size.
• Half the opening clears. A two-panel door opens about half its width. If you want the full width open, stay with hinged doors (see aluminium doors Randburg).

An easy step-through for every age

Older steel doors often have a raised sill that’s easy to trip on. Our StormSeal sliding doors let you choose the threshold when you order:

• Low threshold: a low-profile interlocker for an easier step-through. It’s the better choice for children, older people and anyone using a walking aid.
• High threshold: for a door that faces the weather without a roof overhang.

On Northcliff Hill and the higher parts of Linden and Blairgowrie, doors that face the view often face the storms too. Choose the threshold to suit how exposed the door is.

Keeping the security gate

Most Randburg homes have a security gate or trellis door on the garden door. A swing gate that worked with French doors may not suit a sliding door. Check that the gate still clears the new frame, or plan a sliding gate, and measure it at the same time as the door.

Ordering Aluminium sliding doors Randburg: a five-point checklist

Most delays on aluminium sliding doors Randburg orders come from one of five details. Check them before you order:

• Panel layout: two panels suit standard openings, and 4- and 6-panel doors suit wider ones. See sliding door configurations.
• Which panel slides: every product drawing is shown from inside, so check which panel moves and which stays fixed.
• Range: the Patio range is the most affordable; the Premier range uses heavier sections for wider, taller openings.
• Threshold and track: on aluminium sliding doors Randburg patios that face the storm direction, a roof overhang or a step down outside keeps wind-driven rain off the bottom track.
• Colour: White, Bronze and Charcoal cost the same; Black is about 10% more and Natural Anodised about 20% more.
