GELO Timber Industries possesses three stacking plants: One for construction timber according to customer’s specifications, one for mass-produced articles, and one for boards and formwork. In the stacking plant for construction timber, the planks are labeled on the front end. The labels contain information pertained to the customer: Commission number, part number, dimensions (length, width, and height of the planks), as well as a possible division (in case a certain number of smaller planks is made out of a long piece of timber) are listed.
