Concrete IronSpecification of Concrete Iron in Surabaya
Concrete iron is iron used for reinforcement in concrete construction, better known as reinforced concrete. Reinforced concrete which contains reinforcing bars and is planned on the assumption that the materials cooperate in carrying forces. Reinforced concrete is unique in that two types of materials, namely reinforcing steel and concrete, are used simultaneously. Reinforcement provides a tensile force that concrete lacks and is able to withstand compressive forces.
In general, reinforcing concrete refers to two forms, namely plain iron (plain bar) and screw iron (deformed bar / BJTD). Plain iron is iron that has a round cross section with a smooth or finned surface. Threaded iron or fin concrete reinforcing bars are iron rods with a special surface shape in the form of transverse fins (torsion / fish fins) or elongated ribs (regular / bamboo fins) with a certain pattern, or reinforcing rods that are twisted in the production process.
Threaded reinforcement, which is threaded by a roller process on its surface (pattern differs depending on the manufacturer) to provide better bonding between reinforcement and concrete used in most applications than plain reinforcement with the same cross-sectional area. The thread shape of the fin increases the adhesion to resist movement of the rod relative to the concrete.
Plain reinforcement (BJTD) is rarely used except for wrapping longitudinal (stirrup or spiral) reinforcement which is hooked at its ends, especially in columns.
