Product description Brand name and product description

Precast concrete beams and slabs (or planks and joists) is a construction system that constitutes either precast concrete arched panels, hollow mini-slabs, or planks that are placed between smaller, more frequently spaced precast beams or joists that are spanning between walls or columns. A thin reinforced concrete layer is then poured on top. The precast system doesn’t require the extensive formwork of a cast-in-place concrete slab, and is more flexible for projects that need to be phased such as the improvement of buildings in informal settlements. An example of a manufacturer of precast concrete beams and slabs is  Nyati Slabs in South Africa. It is also a common construction method in India.
