Deformed Bar
A deformed bar is a type of concrete rebar with a rough surface for better cement or mortar bonding. It is a steel bar with surface projections to improve the bond strength when used in reinforced concrete.
A common steel bar, and is commonly used as a tensioning device in reinforced concrete and reinforced masonry structures holding the concrete in compression. A deformed bar is usually formed from carbon steel and is given ridges for better mechanical anchoring reinforced concrete. Steel construction has so many advantages: the strength to weight ratio is excellent, metals join easily, efficient shapes are available, etc. With those advantages, though, come some challenges that are best solved by a good understanding of how the metals actually perform in a structure. For larger buildings, metals are a key element of the structural system. Steel beams and columns, steel joists, steel studs, aluminum framing are a few examples of metal construction.
A wise Superintendent understands not only how to erect the structure, but also the basics of how the structural system works and the ways in which it fails. Engineers, Architects and contractors here in the Philippines mainly use deformed bars as basic construction materials for their project. However, these bars have different sizes and specifications for residential use and large projects such as condo units and commercial buildings.
