Product Information

Sizes smaller than #3 are no longer recognized as standard sizes. These are most commonly manufactured as plain round undeformed rod steel but can be made with deformations. Sizes smaller than #3 are typically referred to as "wire" products and not "bar" and specified by either their nominal diameter or wire gage number. #2 bars are often informally called "pencil rod" as they are about the same size as a pencil.

Bars are typically abbreviated to simply 'N' (hot-rolled deformed bar), 'R' (hot-rolled round bar), 'RW' (cold-drawn ribbed wire) or 'W' (cold-drawn round wire), as the yield strength and ductility class can be implied from the shape. For example, all commercially available wire has a yield strength of 500MPa and low ductility, while round bars are 250MPa and normal ductility. Historically in Europe, rebar is composed of mild steel material with a yield strength of approximately 250 MPa (36 ksi). Modern rebar is composed of high-yield steel, with a yield strength more typically 500 MPa (72.5 ksi). Rebar can be supplied with various grades of ductility. The more ductile steel is capable of absorbing considerably more energy when deformed - a behavior that resists earthquake forces and is used in design. These high yield strength ductile steels are usually produced using the TEMPCORE process, [28] a method of thermomechanical processing. The manufacture of reinforcing steel by re-rolling finished products (e.g. sheets or rails) is not allowed. [29] In contrast to structural steel, rebar steel grades are not harmonized yet across Europe, each country having their own national standards. However some standardization of specification and testing methods exist under EN 10080 and EN ISO 15630: ACI committee 318 (2014).

Mechanical couplers are an effective means to reduce rebar congestion in highly reinforced areas for cast-in-place concrete construction. These couplers are also used in precast concrete construction at the joints between members. Sent by a rebar control when a band is about to be deleted. This notification code is sent in the form of a WM_NOTIFY message. Something to be aware of is that there are a few different types out there, and each is used for a specific purpose. Here is a list of the most common types of rebar used in construction:

Notifies a rebar control's parent window that the control is releasing mouse capture. This notification is sent in the form of a WM_NOTIFY message. Galvanized Rebar: Galvanized rebar is coated with zinc using a variety of processes and is greatly resistant to corrosion.

Delivery charges for prefabricated cages, caps and columns are flat rate on any quantity for your postcode region (1 cage, 50 cages, or more).

Sent by a rebar control when the user changes the layout of the control's bands. This notification code is sent in the form of a WM_NOTIFY message. Notifies a rebar's parent that a break will appear in the bar. The parent determines whether to make the break. Occupational Safety and Health Administration.

Preferred bar sizes in Europe are specified to comply with Table 6 of the standard EN 10080, [23] although various national standards still remain in force (e.g. BS 4449 in the United Kingdom). In Switzerland some sizes are different from European standard.Noville, J.F. (June 2015).

If you are planning to work with concrete or masonry, particularly large platforms, walls, floors, and ceilings, a word you may be encountering is rebar. Sure, you might know that rebar is often found in concrete and structures built of stone.

ASTM A955: Deformed and plain stainless-steel bars for concrete reinforcement (Supplementary Requirement S1 is used when specifying magnetic permeability testing) This type of failure manifested in the partial collapse of the Bixby Hotel in Long Beach, California and total collapse of the Eastman Kodak Building in Rochester, New York, both during construction in 1906. It was, however, concluded that both failures were the consequences of poor quality labor. With the increase in demand of construction standardization, innovative reinforcing systems such as Kahn's were pushed to the side in favor of the concrete reinforcing systems seen today. [12]

The American Welding Society (AWS) D 1.4 sets out the practices for welding rebar in the US Without special consideration the only rebar that is ready to weld is W grade (Low-alloy — A706). Rebar that is not produced to the ASTM A706 specification is generally not suitable for welding without calculating the "carbon-equivalent". Material with a carbon-equivalent of less than 0.55 can be welded.
