Ø20 mm rebar is a working reinforcement in columns, walls, pile caps and slabs of cast-in-place buildings. A Ø20 coupled splice replaces welding and lapping: it saves rebar, removes weld inspection and speeds up installation. For congested and end nodes, weldable (AR) and position (AF, CF) versions are used; for regular splices — standard (B) and swaged (LX-Press).
