About Hogra Holz
Hogra Holz GmbH is a wood processing company based in Limbach-Krumbach (Baden-Württemberg) that processes around 30,000 m³ of wood annually. The company produces planed timber such as wooden laths, battens and special planing profiles, millimetre-accurate cut-to-size pieces with length tolerances of ±0.5 mm, as well as packaging wood. In the pallet sector, Hogra Holz manufactures Euro pallets according to DIN EN 13698, CP and DIN pallets as well as customised special, large-format and single-use pallets up to 4.0 × 7.0 m. Since 2022, the company has operated its own band sawmill for log sawing with logs up to 100 cm in diameter, selling sawn timber raw, dried or finished. Sawmill by-products such as pellets, wood chips, bark mulch and planer shavings are also produced from wood residues. The roundwood comes exclusively from sustainable regional forestry; packaging wood is treated in accordance with ISPM 15.
