Heavy-Heavy (H-H) Industry Picnic Sets feature heavy beams mounted on sturdy supports with an industrial appearance. In contrast to standard H-H Benches, whose supports are concealed under the beams, the supports of H-H Industry beams are visible halfway up the beam. The Streetlock® nuts protrude through these plates to allow for fixing of the beams. The Streetlock© system extends the lifespan because the beams are easy to rotate, even after ten years. An attractive connecting support unit enables extra-long picnic configurations. The supports are made of hot-dip galvanised steel, Corten or powder-coated steel. The picnic sets have standard lengths of 234 and 300 cm - 92” and 118”. The H-H beams are made from hardwood or Lava Grey, a maintenance-free recyclate. Lava Grey is a sustainable alternative to wood and consists entirely of recycled household plastic waste.
