Ribbed rebar 36 500 Saba steel

Steel bars are generally used to strengthen concrete and rock structures to withstand tensile forces. Concrete is inherently strong enough to withstand compressive forces, but tensile forces can break it.

The rock structures and mortar walls are almost concrete-like and have relatively poor tensile strength. Some standard rock pieces, such as blocks and bricks, are designed to have special holes for reinforcing rebars. Although high strength tensile materials can be used as reinforcing agents to enhance the tensile strength of concrete, steel and concrete have a particular commonality, which makes them more used than steel for the construction of reinforcing rebars. This is a common aspect of the thermal expansion coefficient and its close proximity to steel and concrete causes the same lengths to change at different temperatures to prevent additional internal stresses in the concrete structure, thus preventing premature destruction of the concrete.

 Rebar grooving is intended to improve adhesion between concrete and reinforcing steel. The tread design on the rebar has no specific specifications, but the spacing between the tread and the tread height must be in accordance with the relevant standards. Treads made on the steel body often provide adequate adhesion to the steel and concrete by providing sufficient friction surface, but are still likely to be removed by a force sufficiently strong.
