Frequently asked questions
Which roof drain should I use on a flat concrete roof?
A dome roof drain is the usual choice for open roofs, because the raised dome keeps water flowing even when debris builds up. Use a flat grate where the roof is used as a terrace.
What outlet sizes do you supply?
3" and 4" outlets are the most common; other sizes are available on request.
Do you supply rainwater outlet flaps?
Yes – stainless steel outlet flaps for downpipes and wall outlets.
Can you match an existing drain or a consultant specification?
Yes. Send the specification, a photo or the existing model and we will offer a matching product.
Do you deliver outside Dubai?
Yes, across the UAE, and to GCC projects on request.
