Unlike concrete steps poured on site, our precast concrete steps are manufactured within our production plant. These hollow units are lighter, which makes them less likely to settle. We make sure the treads, risers and landings of our stairs are made as one solid piece.

Such concrete units are called as the precast concrete. The examples of precast concrete units are concrete blocks, the staircase units, precast walls and poles, concrete lintels and many other elements.
Concrete Block Types. Concrete Blocks are also known as Concrete Masonry Units (CMU) in the masonry industry. Being the core building material of masonry structures, concrete blocks are available in a variety of styles, sizes, and colors.
Weight concrete (NWC). NWC unit weight: 150 lbs/ft3 (2400 Kg/m3) Aggregates with bulk densities less than 70 lbs/ft3 (1120 Kg/m3) are called Lightweight. Aggregates weighing more than 130 lbs/ft3 (2080 Kg/m3) are called heavyweight. Aggregates in Concrete Concrete Technology 10 Rocks are classified according to origin into three major groups: 1.
