12mm Rebar

T12 12mm Rebar Concrete Reinforcing Bar

12mm rebar is commonly used in the construction industry within commercial as well as domestic ‘DIY’ projects of varying sizes. Its primary function is to improve the tensile strength of concrete and to balance load through slabs, columns, beams, and other structural elements. T12 rebar is often used in prefabricated components such as pile caps, beams, and walls, as well as mesh sheets including B1131.

While reinforcement bar is not often supplied galvanized or epoxy-coated, hot rolled bars commonly leave the mill with a thin coating of mill-scale (iron oxides), which helps to protect the steel. After a time, this coating will dissipate, and surface rust can appear due to environmental factors. Rust that is caused by fresh water (rainwater) does not, however, decrease the inherent strength of the rebar, nor will it lead to further deterioration of the bar when cast in concrete. In fact, certain levels of rust (up to 2%) have been shown to improve the bonding of rebar in concrete. Additionally, given correct concrete cover, corrosion does not continue within concrete structures unless the concrete has either high permeability or other imperfections.
