A rule of thumb estimate for development and lap length is 40 diameters. For 20 mm bars that is a large but reasonable 80 cm, but it becames 128 cm for 32 mm bars and 2 meters for 50 mm bars. Lap length problem can be avoided by using mechanical connectors, but 2 meters development length would waste a lot of steel and need a large space, very often unavailable. Get price

Overlapping Of Steel Bar

Rebar Lapping is inevitable if a run of the rebar is larger than one solid piece. Under this situation, it is required to overlap the bar in that line. It should be noted that the overlap should not be provided in bars with diameter in excess of 36 mm. In such a situation Get price
