Nailing plates are manufactured from metal plate 0.9 to 2.5 mm thick. They are used in pairs symmetrically on both sides of the wood parts to be connected. The lamination method of lattice structures using nailing plates in large supports is based on bonding several nailing plate lattices together.
Spiked plates are made by welding spikes to a steel plate. These are well suited for use particularly in robust structures.
