" Bent steel. Bending diameter D at the middle of the bend, no less than five times the bar diameter. Stirrups.

Stirrup adjustment, namely to increase the length and curved hook adjustment or difference between the value of the two and, according to the hoop size or the amount of outsourcing package size. Steel cutting length should be considered based on component size, concrete cover thickness, steel bending adjustment value and increase the length of the hook and so forth.
