may i know how to recognize type of steel and size of BRC?
I believe u mean those reinforcement bar embedded inside concrete. there are 2 type, 1 is steel bar (like a round bar) and there categorize base on diameter of the bar. eg. T12, T16, T20, T32, R6, R10, Y20.
R = round bar (the surface of bar is smooth and yield stress is lower)
T = high tensile bar (the bar made by twisting of bar hence have high yield stress)
Y = higher tensile strength than "T" type of bar.
the number represent diameter. 12mm, 25mm, 32mm and etc. steel bar come in standard length 12m long.
another type is BRC (BRC is a company name). that is wire mesh consist of small steel bar welded together in a mesh. it come with size 6m x 2.2m each piece. these BRC made by smaller size of round bar like R6, R5, R4 and etc. using BRC can save time as u don't have to tie the steel bar as it come welded from factory. BRC got the reference code, each reference ode give u the spacing of the small round bar welded and diameter of bar used. so engineer can design base on their requirement when come to structural design.
