The Siero Group is the fourth generation of a family company with more than 80 years in the timber sector. Throughout its history it has specialised in sweet chestnut wood and is currently the largest supplier of this species in the world. Grupo Siero is made up of 2 companies : Maderas Siero and Siero Lam.
Maderas Siero
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.
