Product Description
Short for "reinforcing bar," rebar is refers to metal - usually steel - that's used to help increase the tensile strength of concrete for a variety of needs, including many of the most common construction types you see every day.Concrete is known to be weak in the areas we just mentioned, at least compared to steel and other metal types. If this reinforcement was not used, these structures would at-risk of falling apart.
Rebar usually will be built so the metal component is not visible within the structure. Rather, it will be buried within the concrete. It's usually made with ribs rather than smoothly, allowing it to avoid slippage within its structure.
How Rebar is Made
As we noted above, the most common material for rebar use is steel, which is used because of its excellent tensile properties. It's often made from forms of recycled steel, which will be melted down using an electric arc furnace, cooled using billets, and then stored until it's needed.
From here, billets can be reheated to an elevated temperature and fed through extrusion tools, then necked down until its proper size is reached. Finally, it will be tooled to create the proper ribbing, which we noted above is in place to prevent slippage within concrete. Then it will be sheared to the proper length, and it's ready to go.

Rebar, or reinforcing bar, is used in many masonry and concrete projects to reinforce slabs and structures. Because concrete has low compressive strength, rebar helps it bear loads without cracking.
Therefore, for most concrete projects, rebar is required to help the slab, footer, or foundation maintain its structural integrity. Rebar is available in standard sizes, making it easy to find the weight and dimensions of the rebar for your project.
The first step is to identify which size of rebar is being used on the project, for example, a #3 rebar. Most home and residential projects will use #3, #4 or #5 rebar, with #3 being used most commonly for patios and driveways, #4 for walls and columns, and #5 for footers and foundations.
The next step is to identify how much linear footage of rebar will be used. Linear footage is the total amount of length in 12″ increments needed for the project.
For example, if you need 20 pieces of 60′ rebar, you will need 1,200 linear feet of material. Rebar is typically sold in 20′, 30′, 40′, and 60′ lengths, but it is possible to order custom lengths as well.
Refer to the charts below for the dimensions for each size of rebar. Find the diameter and area of the rebar along with the weight per linear foot. To find the total weight, multiply the total length of rebar - total linear feet of material used - with the weight per linear foot if measured in feet, or weight per meter if measured in meters.

Quality Inspection
The testing institution tests the quality of the products to ensure that they meet the production standards. Product quality is strictly controlled by inspection personnel to ensure zero product defects.
Steel rebar are mainly subjected to tensile stress in concrete. The deformed steel bar has a greater bonding ability with concrete due to the action of the ribs, and thus can better withstand the external force. Rebar is widely used in various building structures. Especially large, heavy, lightweight thin-walled and high-rise buildings.
The main uses of deformed steel bar
Rebar is a small type of steel, mainly used for the skeleton of reinforced concrete building components. Rebar is usually used in reinforced concrete, the effect of its stripes is to increase the friction force, make rebar and concrete bite together, form one,under the action of external force will not produce twitching phenomenon, improve the strength of concrete. Rebar is widely used in civil engineering construction such as houses, bridges and roads. From public facilities such as expressways, railways, bridges, culverts, tunnels and flood control dams to the foundation, beams, columns, walls and plates of housing buildings, threaded steel is an indispensable structural material.
