In time, the Kemi bioproduct mill will send 50 daily shipments to the port warehouse at the Port of Ajos. Each lorry will hold roughly 70 tonnes of cargo.
Wood is well-suited for a northern maritime climate Construction of the port warehouse at Metsä Fibre’s new Kemi bioproduct mill used 5,000 cubic metres of Nordic wood. The 465-metre long building with 37,500 square metres of space has a roof structure with load-bearing glulam beams manufactured from Metsä Fibre’s sawn timber. The roof elements installed over the beams have been made from Metsä Wood’s Kerto® LVL and roofing plywood. The entire roof structure of the product warehouse is wood, and will be finished at the end of 2022. There are 153 pieces of 14.5-metre longitudinal load-bearing glulam beams and 189 pieces of 26.5-metre transverse ridge and bottom beams. On top of these beams are the roof elements made of laminated veneer lumber and plywood. In total, there are 39,000 square metres of elements. “With the right design, it is possible to construct very large structures from wood products,” says Pasi Pulkkinen , Vice President, Land Logistics at Metsä Group. He explains that careful surface treatment of the wood ensures that it stands up to the stresses of the maritime climate and varying seasonal conditions. “We wanted to utilise wood as the construction material for the warehouse. This particular structure is by the sea and has no heating. It is used to store pulp, which creates heat and moisture inside the warehouse. These conditions require that the roof structure tolerates the climate and has excellent moisture resistance.”
