BS 4449 is the British Standard specification for ribbed, weldable reinforcing steel for reinforced concrete, supplied as bar, coil, or decoiled product. To match this to your program, talk with our team.
What BS 4449 Covers
It defines the grades and mechanical requirements for weldable rebar, verified by tensile and bend testing to confirm strength, ductility, and weldability suitability.
How the Test Is Run
A rebar sample is pulled to failure with high-force grips, and yield, tensile strength, and elongation are checked against the grade; bend tests confirm ductility.
Why It Matters
Weldable rebar verification underpins reinforced-concrete safety; high-force serrated grips and a bend fixture sized to the bar are essential.
