Rebar
The nominal diameter of the steel bar is 8-50 mm, and the recommended diameters are 8, 12, 16, 20, 25, 32, 40 mm. Steel types: 20MnSi, 20MnV, 25MnSi, BS20MnSi. Steel bars mainly bear tensile stress in concrete. Due to the effect of the ribs, the deformed steel bar has a greater bonding capacity with the concrete, so it can better withstand the external force. Steel bars are widely used in various building structures. Especially large, heavy, light thin-walled and high-rise building structures.

Rebar, short for “reinforcing bar” or “reinforcement bar”, is a metal bar that is used to help increase the tensile strength of concrete. As a result, it helps concrete structures withstand tensile, bending, torsion, and shearing loads. Since these are areas of weakness for concrete, rebar strengthens concrete structures that would otherwise fall apart under these forces.

 

Rebar is not typically visible in concrete structures because it is usually buried within the concrete structure. It is almost always made of steel because steel has thermal expansion properties like concrete which reduces temperature change issues. Rebar is usually not smooth, it is made with ribs to prevent slippage within the concrete structure.

How is rebar made?


Rebar is almost always made from steel, which has excellent tensile properties relative to concrete. Interestingly, it is commonly made from recycled steel such as old cars, appliances, and machinery that are melted down with electric arc furnaces, cooled in the form of billets, and then stored. Once the billets are ready to be used for making rebar, they are reheated to an elevated temperature (but below their melting temperature) and are fed rapidly through a series of extrusion tools. The different stages of extrusion tooling continue to neck down the steel billet into smaller and smaller diameter rods until the desired rebar diameter is achieved. A set of tooling creates the deformations needed to prevent slippage within the concrete. The rebar is then sheared to the desired length.

 

How does rebar work?


The tensile strength of the steel rebar complements the compressive strength of concrete to create structures that have a blend of both types of strength. This reduces the risk of fractures and allows the structure to better withstand movements and forces that might otherwise cause a concrete structure to fail.


Rebar is often laid in a grid pattern. This means that different segments of rebar are placed parallel and perpendicular to one another so that it can withstand tensile forces from many directions. The deformations on the exterior of the rebar ensure that the rebar does not slip out of the concrete structure. Sometimes rebar is bent at the ends to further anchor it in place within a concrete structure.

Packaging and Shipping


We adopt standard export shipping packaging and bundles steel strips according to the size of the rebar. According to our delivery experience, a 20-foot container can hold 22 tons of carbon steel, and a 40-foot container can hold 25 tons of carbon steel. For larger orders, we use bulk vessels to transport you, and the price is cheaper. Also, we can customize the packaging according to the needs of customers.
