Maderas Siero S.A.
Asturian sawmill, leader in chestnut wood, with its own certified woodland and integrated chain.

Sawmill and forestry company from Argüelles (Siero, Asturias), with family origins in 1934 and current facilities since 1982. It specialises in chestnut wood, of which it considers itself a European and world leader: in primary processing it produces beams, pontoons and boards, and makes use of the offcuts for pellets. It manages more than 200 hectares of its own certified woodland and, together with its sister company Siero Lam (laminated wood, boards, profiles and flooring, created in the 1990s), commercially forms Grupo Siero, integrating the chain from forest to finished product.
Because it puts chestnut wood into building projects with genuine traceability from its own FSC and PEFC certified woodland, integrating forest, sawmill and processing without intermediaries.
