Specially designed system to fit the panels for Main and Edge Beams. It is very easy to assembly and dismantle. Three main parts compose the system: Straining Pieces, Guides and Crossing Pieces. The Straining Piece, with its closing profile, is where we fit the wood panels. The Guide forms the streets and here we will fit the Straining Pieces. The Crossing Pieces will support all the structure after all the plant has been formed, recovering 85% of the element of all the structure, supporting the weight of all the structure. We fit one Crossing Piece every two wood panels. It is recommended depending on sizes to fit panels bracing the ribs between beams to reduce formworks weight.
