In MADERAS SIERO S.A. (1970), we work from the forest and we make a first transformation of the wood. We have our own managed forests (FSC and PEFC), and our activity includes forestry exploitation, sawing, drying and commercialisation of both national and imported wood. We specialise in sweet chestnut wood, a native forest species managed in a sustainable way.
SIERO LAM, S.A. was created in 1995 for the manufacture and distribution of second transformation products: glued and/or moulded solid wood products.
Siero Lam represents a forward vertical integration by the Siero Group, which allows the sweet chestnut harvesting to be optimised to the maximum.
