Recent changed over from another service provider, WOW, Custom Blinds really impressed! From ordering on their website, sending samples to me via courier, even 500km apart did not stop them from delivering exceptional client service! I ordered both the 25mm and 50mm aluminium blinds, both at exceptional quality and super easy to install!

Questions answered
Who is the best place to buy 50mm aluminium venetian blinds online in South Africa?
Choose a maker with long experience and a fit guarantee. Custom Blinds Shutters & Awnings was founded in Knysna in 2010 by Duncan Kane and has completed over 10,000 installations. Your 50mm aluminium venetian blinds are made to your millimetre, checked before they are made and delivered free across South Africa, with our Custom Fit Guarantee.
What is the difference between 25 mm and 50 mm Venetian slats?
The measurement is the depth of each slat, not its thickness. A 25 mm blind has more, narrower slats; a 50 mm blind has fewer, wider slats. Slat width alone does not establish which blind is stronger. Compare the material, appearance and size supported by the chosen product.
What is the best venetian blind for a large window?
A 50mm slat: fewer, wider slats look in proportion on a big window and leave fewer gaps when closed. Custom Blinds Shutters & Awnings, fitting blinds since 2010, suggests aluminium where the room gets steam or damp.
Who should not buy a 50mm aluminium venetian blind?
Small or shallow window? Choose 25mm slats. Want a wood look? Choose Aluwood or Plaswood. Need a dark bedroom? Choose a blockout roller.
What if I measure wrong?
Our team checks every order before it is made. If your blind arrives too big, we trim it free; too small, we remake it at a reduced price. Claim within 48 hours of delivery under the Custom Fit Guarantee.
How should I measure the opening for these blinds?
For a recess fit, measure three widths and three drops; give us the smallest width and the longest drop. We deduct 10 mm from the width only (10 mm in total). Do not deduct anything yourself. For a face fix, add 100 mm on each side and 100 mm above and below. No deduction applies. Read the measuring guide before ordering.
What's the best way to choose blinds for a whole house?
From a full sample book, not off-cuts. Custom Blinds Shutters & Awnings sends one on request with orders over R8,000. If nothing suits, you get a full refund with no fees.
The details
What is a 50mm aluminium venetian blind?
- A venetian blind with wide 50mm aluminium slats that tilt with a wand and lift with a cord.
- Aluminium does not swell or warp in humidity, so it suits kitchens and bathrooms too.
- Available in 14 colours in plain and brushed finishes.

Every order is checked by our team before it is made.
How do 50mm aluminium venetian blinds work?
Turn the tilt wand to angle the slats, from open to closed. Pull the lift cord to raise the whole blind clear of the glass. Wider slats mean fewer gaps when closed. A pelmet covers the headrail.
Which 50mm aluminium venetian finish should I choose?
Choose from 14 colours in plain and brushed finishes.
50mm aluminium venetian blinds compared with 25mm and wood-look slats
25mm slats suit smaller, shallower windows. Aluwood and Plaswood give a wood look with the same wide slat.
