Planed wood

Wood Work bundling.

The tree from the forest comes as a trunk, with branches and bark-freecut at the sawmill. The sawmill provided the wood processing industry such as furniture manufacturers and timber, with  planks, beams and frames. The wood supplied is graded by quality, sawn in standard sizes and then combined.
Such cargo includes hundreds of pieces and weighs about 500 to 700 kg. This load in times past was bundled together using wire, and later steel tape.  Both applications have the same disadvantage: wire and steel tend to loosen, so that the beams are no longer being held together. Furthermore, there is rust  left behind, which the user does not accept. Plastic strapping material has become more successful. However, only the high-strength polyester strap is suitable.
