Pre-stressed concrete planks are primarily used for floor and roof decks. Serving as a combined deck and ceiling system, the planks erect quickly to reduce on-site labour needs and are capable of spanning long open spaces to aid design flexibility. Continuous, interior voids and structural stability reduce weight and, therefore, reduce cost. The result is a sound proof, fire rated, low maintenance system with long spans and shallow depths.

Flat slab is generally the most economical slab system for column grids with aspect ratio of not more than 1.4, based on the average cost index in Singapore and other developing countries in South East Asia and South Asia.

Pre-stressed Concrete is an architectural and structural material processing great strength. The unique characteristics of pre-stressed concrete allow predetermined, engineering stresses to be placed in members to counteract stresses that occur when the unit is subjected to service loads. This is accomplished by combining the best properties of two quality materials: high strength concrete for compression and high tensile strength steel strands for tension.

A hollow core slab, known as voided slab or hollow core plank, is a precast slab of pre-stressed concrete typically used in the construction of floors in multi- story apartment buildings. The slab has been especially popular in countries where the emphasis of home construction has been on precast concrete, including Northern Europe and socialist countries of Eastern Europe. Precast concrete popularity is linked with low-seismic zones and more economical constructions because of fast building assembly, lower self-weight (less material), etc. .

Pre-Stressed Galvanized Strand has the same physical properties as pre-stressed strands except that the individual wires are galvanized and then stranded. The galvanizing is used to prevent corrosion. Galvanized strands are commonly used in construction of Stay Cable Bridges and Egg Shaped Digesters Waste Water Treatment Plant.

High Tensile wire product is used in pre-stressing concrete for flooring in residential housing and precast concrete products: concrete pipes, railway sleepers, pc piles and posts and ground anchors, etc.
