Reinforcement steel (rebar) is essential in construction, providing tensile strength to concrete structures. Understanding rebar sizes and weight is critical for accurate material estimation, structural design, and cost planning. This guide provides a complete overview of rebar sizes, weight calculations, and practical selection guidance for UK and international projects. Quick Summary: Rebar Sizes & Weight Common sizes: 6mm to 25mm Most used: 10mm, 12mm, 16mm Weight formula: D² ÷ 162 Sold per ton Used in slabs, beams, columns, and foundations What is Rebar? Rebar (reinforcement steel) is used to strengthen concrete structures by improving [...]
