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.

You can use our rebar material calculator to find out how much rebar you need for your project. Alternatively, multiply the length of rebar by the quantity used to find the linear footage. Learn more about how to find linear footage.
We've put together a handy online tool for calculating the weight of rebar, you can easily get the individual and combined weights for your next project. Rebar (reinforcing bar) is usually available in industry standard sizes which makes it possible for us to calculate the weight, simply enter the lengths and quantities you need and the tool will do the calculations.
Rebar is either in the form of a steel reinforcement bar or a mesh of steel wires and is used in reinforced structures to hold and strengthen the concrete, it also reduces the tension placed on the concrete. Rebars have been used in the construction of reinforced structures for more than 500 years, and are still widely being used.
Concrete is a highly compressible material but it lacks the capacity to withstand tension. To compensate for this lack, rebars are cast into the concrete for effectively bearing the tensile loads. Rebars not only support the entire design load of the structures, but also aid in the durability by resisting cracks in the surface and resisting the stress caused by external factors such as temperature and shrinkage.
Steel and concrete have similar coefficients of thermal expansion; thus a concrete structure with rebars will experience a minimal stress because of similar expansions of the two materials caused by any changes in temperature. Extra care needs to be taken while transporting and handling these bars because any damage will reduce the long-term corrosion resistance.
Rebar cages are made using hydraulic benders and shears, and can be made either on-site or off-site. The rebars are placed using either steel fixers or concrete reinforcing iron workers. Plastic rebar spacers are used to keep the rebar separate from the concrete framework, ensuring proper embedment. The rebars can be tied together using a variety of mediums such as electric rebar tier, spot welding, mechanical connections, and tying steel wire. Epoxy coated or galvanized wire is used for tying epoxy coated and galvanized rebars. For safety purposes, the projecting ends of rebars are often bent or covered with special steel-reinforced plastic caps.
For each type of rebar that you require in your project, select the diameter from the dropdown, then adjust the length to suit your requirements, and enter the number of units you need for that specific diameter and length combination. The calculation will update dynamically to give you the total weight of that line item. At the end of the row, there is a dropdown selector for you to add the Shape Code you need for that line item. Shape Codes can be checked using the pop-up list provided (click See List above the Shape Code field).

Always consult a qualified engineer and/or architect when designing or carrying out any construction project. Always work within regulations set out by your government, and within recommended safety guidelines.
Not necessarily. When you expect heavy loads on the surface, you will require rebar because the weight will cause concrete to experience tension stress. However, we always recommend checking with a specialist.
You should avoid welding rebar. Instead, you should use a steel wire of one-sixteenth of an inch (1.6 mm) to tie the rebar together. Rebar steel material typically has high carbon content, which makes them fragile after the thermal stress of uncontrolled welding. As a consequence, a structure with welded rebar may fail at a lower tension than what it was designed for.
Rebar calculator helps to find out how many rebars you need to create reinforcement in a concrete slab and how much it will cost you. Moreover, it can estimate the grid dimensions that you should use. In the article below, you will find out what rebar is, check the rebar sizes, and find the step-by-step tutorial on how to use the rebar calculator.
Rebar (reinforcement steel/reinforcing steel) is a building material used to improve the properties of concrete blocks. Those wires are made of patterned steel (improves adhesion), and they are usually placed in a way to create a mesh. Thanks to the steel characteristics (thermal expansion coefficient very similar to the concrete's), reinforcement compensates for the low tensional strength of concrete. Rebar may boost the resistance to concrete failure by as much as several times.
Civil engineers apply reinforcing steel when designing buildings and poured concrete driveways. You can estimate how much it costs with our concrete driveway cost calculator. Besides the increased tension resistance, rebar also improves concrete cracking resilience and allows for reducing the thickness of concrete blocks.
Don't worry about your rebar calculations. All that math behind the construction planning might be quite confusing, but the rebar calculator takes this upon itself. It calculates the following parameters:
Total length of needed rebars. To calculate this, we need to know how many vertical and horizontal lines of rebars will be placed. For example, the number of rows is calculated by dividing the grid length by the rebar-rebar spacing. To obtain the length of rebars, multiply this number by the grid width.
The Rebar Calculator contains equations and data used in working with reinforcement bars (rebar) in concrete slabs. The formulas calculate materials needed for rectangular, circular and irregular shaped slabs. (para espaol, HAGA CLIC AQU) .
General Rebar InformationRebar is short for reinforcing bar. Rebar is a roughly circular steel bar with ribs used to provide added tensile strength to concrete structures. Rebar is put in place before concrete is poured. When the concrete has hardened, the concrete around the rebar ribs keep the rebar in place. Rebar and concrete expand similarly with temperature variations. This all has the net result of substantially added tensile strength when rebar is part of the concrete form. Carbon steel is the most commonly used material for rebar, which may also be coated with zinc or epoxy resin.
Rebar is laid out in grids, crisscrossed patterns of rebar, tied at the intersections where runs of rebar touch. The grids have spacing between the rebar rows, and they are placed within the concrete form by a specified inset from the edge of the concrete. Multiple parallel grids, at uniform space intervals, are referred to as rebar mats.
In the United States, rebar sizes are in increments of 1/8th inches in diameter. Therefore, size 4 is 4/8th of an inch, which is 1/2", and size 8 is a full inch in diameter. Based on this and the density of steel used in rebar, the Rebar Size Table contains reasonably accurate specifications of rebar linear weight and lateral (face) area based on rebar size.
The most common lengths of pre-cut rebar in the United States are 20`, 40' and 60'. These are known as rebar sticks. When the dimensions of a slab, wall or other form exceed the length of a single stick of rebar, it is required to overlap and tie rebar pieces to create the added length. This process is called lapping, and the length of the overlapping rebar is the rebar lapping length. The length of the lap is specified by a "Lapping Factor (LF)" which is often 40 or 60 times the diameter of the rebar. Engineering specifications of a lapping factor should always be applied.
The Rebar in a Wall function also computes the size of the forms. Concrete forms are a vital part of construction. The Form Area of Concrete Wall function in this calculator helps compute the amount of plywood or OSB needed to construct the forms. It give you the choice of specifying whether you want to compute:
The Rebar Calculator is now available in Spanish. It has Spanish language descriptions, labels and diagrams and it also has default units in the metric system (SI). The lengths are in meters and centimeters, the areas are in square meters, the volumes are in cubic meters, and the weights are in kilograms and metric tons.
This calculator can be used as an aid to help estimate the weight of bolts, nuts, and washers. We provide it as a resource for our customers, because the weight of a bolt or assembly is often needed when calculating shipping costs, or jobsite delivery requirements. 152ee80cbc
