EN 10080:2005 – Steel for the reinforcement of concrete – Weldable reinforcing steel – General
1 Scope
1.1 This European Standard specifies general requirements and definitions for the performance characteristics of weldable reinforcing steel used for the reinforcement of concrete structures, delivered as finished products in the form of:
bars, coils (rod, wire) and de-coiled products;
sheets of factory-made machine-welded fabric;
lattice girders.
1.2 Steels according to this European Standard have a ribbed, indented or smooth surface.
1.3 This European Standard does not apply to:
non-weldable reinforcing steel;
galvanized reinforcing steel;
epoxy-coated reinforcing steel;
corrosion resistant reinforcing steel;
prestressing steels (see prEN 10138-1 to -4);
indented strip;
further processing, e.g. cutting or cutting and bending.

3 Terms and definitions
For the purposes of this European Standard, the terms and definitions given in EN 10020:2000 and EN 10079:1992 and the following apply.
3.1
reinforcing steel
steel product with a circular or practically circular cross-section which is suitable for the reinforcement of concrete 3.2
ribbed reinforcing steel
reinforcing steel with at least two rows of transverse ribs, which are uniformly distributed over the entire length
3.3
longitudinal rib
uniform continuous protrusion parallel to the axis of the bar, rod or wire
3.4
transverse rib
any rib on the surface of the bar, rod or wire other than a longitudinal rib
3.5
rib height, h
distance from the highest point of the rib (transverse or longitudinal) to the surface of the core, to be measured normal to the axis of the bar, rod or wire
3.6
rib or indentation spacing, c
distance between the centres of two consecutive transverse ribs or two consecutive indentations measured parallel to the axis of the bar, rod or wire
3.7
angle of transverse rib or indentation inclination, ß
angle between the axis of the transverse rib or indentation and the longitudinal axis of the bar, rod or wire
3.8
transverse rib flank inclination, α α
angle of the rib flank measured perpendicular to the longitudinal axis of the rib
