About Holzwerke Bullinger
Holzwerke Bullinger produces timber construction products for structural timber engineering at its sites in Abtsgmünd (Baden-Württemberg) and Märkisch Linden near Neuruppin (Brandenburg). The portfolio includes glulam (BSH) in strength classes up to GL32, solid BS ceiling elements (BSD), structural solid timber (KVH), Duo-/Trio laminated beams, wall timber and LVL made from Kerto laminated veneer lumber in cooperation with Metsä Wood. The wood species used are predominantly Nordic and European spruce, pine, fir as well as larch/Douglas fir; bonding is done with melamine resin or PUR adhesive according to DIN 68140/68141 (DIN EN 385). The laminations are machine-sorted according to EN 14081 on a strength grading machine from Microtec (T11–T26, L30, L36, visual S10/S13, C24). Using CNC joinery systems, components with cross-sections up to 1,250 mm wide and lengths up to 22.80 m are milled, drilled, slotted and marked (up to barcode), as single-part or series production including CAD layout planning and list production without offcuts. Customers include timber house construction and element prefabrication, roof truss construction, passive building and trade fair construction. The glulam is manufactured according to EN 14080 and is subject to third-party surveillance by MPA Stuttgart.
