POSI JOIST joist - a type of floor beam that consists of two parallel strips made of lumber (upper and lower), connected by metal fasteners that are a combination of cross-braces with barbed plates. This construction combines the lightness of the timber with the strength of the metal elements, creating an openwork structure that allows installations (electrical, plumbing, ventilation) to be easily routed between the cross-bracing.
Thanks to its design, POSI-JOIST beams are not only lightweight but also very strong and stable, making them ideal for use in floor and roof constructions, especially where load-bearing capacity and flexibility in the adaptation of technical spaces are required.
