Building Materials
Cement, sand, bricks and pre-mixes for the foundations up.
Boksburg building merchant since 1956
Rainbow Builders Supplies has kept Boksburg contractors and homeowners stocked since 1956, with over 30 000 line items across seven departments. Our own fleet delivers throughout Gauteng at an added fee.
Our story
Rainbow Builders Supplies opened its doors in 1956 and has stayed family owned and family run ever since. Trading also as Rainbow Mica Build, we were one of the founder members of the Mica organisation, the hardware group that has grown to more than 160 stores across South Africa. We have kept our own counters in Boksburg all along.
We do not just sell hardware, we understand it. That means stocking more than 30 000 line items across building materials, timber, steel, ceilings, plumbing, hardware and paint. Two branches in Boksburg put that stock and that knowledge close to home.
What we stock
From foundations to finishing touches, it is all in stock at Rainbow.

Cement, sand, bricks and pre-mixes for the foundations up.

Steel and concrete products for structural work on any site.

Plumbing and sanitary ware for wet areas throughout the build.

Ceilings, fascias, doors, windows and fittings to close up the build. Ask at either counter.

This is what stocking 30 000 line items actually looks like.
