Product Information

Something that is important to note is that rebar used to be made out of new steel. However, during the 1960s, rebar started being made out of scrap metal. At this time, rebar contains up to 97% recycled materials, making it fairly eco-friendly. Delivery charges for prefabricated cages, caps and columns are flat rate on any quantity for your postcode region (1 cage, 50 cages, or more). At The Metal Store we have a wide range of mild steel rebar available in 8mm, 10mm, 12mm, 16mm, 20mm, and 25mm diameter pieces which are supplied in 3m or 6m lengths. This plethora of sizes ensures you have the perfect starting point for getting the correct size bar for you project.

BS 4449: Steel for the reinforcement of concrete. Weldable reinforcing steel. Bar, coil and decoiled product. Specification. (2005/2009)

When US/Imperial sized rebar are used in projects with metric units, the equivalent metric size is typically specified as the nominal diameter rounded to the nearest millimeter. These are not considered standard metric sizes, and thus is often referred to as a soft conversion or the "soft metric" size. The US/Imperial bar size system recognizes the use of true metric bar sizes (No. 10, 12, 16, 20, 25, 28, 32, 36, 40, 50 and 60 specifically) which indicates the nominal bar diameter in millimeters, as an "alternate size" specification. Substituting a true metric size for a US/Imperial size is called a hard conversion, and sometimes results in the use of a physically different sized bar.

What is Rebar?

Rebars are available in the following grades as per IS:1786-2008 FE 415/FE 415D/FE 415S/FE 500/FE 500D/FE 500S/FE 550, FE550D, FE 600. Rebars are quenched with water at a high level pressure so that the outer surface is hardened while the inner core remains soft. Rebars are ribbed so that the concrete can have a better grip. Coastal regions use galvanized rebars to prolong their life. BIS rebar sizes are 10, 12, 16, 20, 25, 28, 32, 36, 40 and 50 millimeters.

The most common type of rebar is carbon steel, typically consisting of hot-rolled round bars with deformation patterns embossed into its surface. Steel and concrete have similar coefficients of thermal expansion, [2] so a concrete structural member reinforced with steel will experience minimal differential stress as the temperature changes.Also known as rebar, reinforced bar is a highly durable product which is typically used in the building trade for adding stability to concrete. Casting mild steel reinforcement bars into footings ahead of pouring fresh concrete vastly improves the structure’s tensile strength.
