Count 6.0 × 2.4 m SL mesh sheets for a slab with overlaps, plus bar chairs and total steel weight.
Your measurements
How it's worked out
Sheets along each side = (side − lap) ÷ (sheet side − lap), rounded up. Steel weight uses the bar diameter of each SL mesh at 200 mm centres both ways. Chairs are placed on a square grid at the spacing you choose.
