Developing from the family craft business founded in 1929, the Jacob Group specialises in the manufacture of wooden components for the construction industry. Its manufacturing activities are concentrated around two distinct areas:
- The manufacture of “Roof Trusses”: JACOB Structures Bois, a subsidiary, manufactures industrialised roof trusses and traditional, digitally cut roof timbers
- The manufacture of “Pre-fabricated framework, walls and coverings for buildings”:
POBI, another subsidiary, offers a complete range of manufactured pre-fabricated components (floors, walls and roof parts) finished in the factory and destined for professionals working in the construction of private houses, social housing, professional premises and collective buildings.

Glulam has been called the grandfather of engineering wood, because the first glulam engineered timber was produced over a century ago....log before I Joists of LVL.
Today, glulam is still a fresh choice for designers because of its strength, economy and ambiance. Straight, tapered or curved, it can be ordered in a range of sizes for all types of applications. Its strength for long spans can provide unobstructed view with minimal need for columns or posts.
Glued laminated wood arches, beams and trusses are also a renewable resource, because US foresters plant 5 million trees each day to insure a future supply of wood. this contrasts with steel and concrete, which deplete natural resources.
The combination of high strength and large sizes makes glulam timbers ideal as main load carrying members which can span over 100 feet. In residential construction, glulam beams are commonly used for headers and beams supporting large portions of floor and roof systems.
When glulam materials arrive at the jobsite prefinished or pre-drilled , the delivered product is the finished product. this makes glulam unique as a structural component for many kinds of buildings. other types of framing members arrive on site in raw form, and require additional cladding to create the final production.
Glulam timbers are available in four appearance grades; premium, architectural, industrial and framing.

HAAS nail disk binder
Already 1972 decided Xaver Haas, as one of the first enterprises in Germany, for the economically favorable and various nail disk technology. Until today HAAS could constantly remove its technical projection/lead. Thus HAAS convinces each day on the new with innovative roof structures.
The economical nail disk binders are industrially manufactured with HAAS properly matching after your individual planning.
At the beginning of the manufacturing process cut our specialist within shortest time according to the felling trees hurry the CAD Konstruktionszeichnung. Static requirements as well as the desired intended purposes of the owner are considered. Subsequently, our skilled workers press the nail plates from hot-dip galvanized or not rusting steel reciprocally at the junctions into the worked on wood.
After the industrial completion the reliable just in time supply of the construction units takes place on the building site. After it the assembly takes place briefly on the intended sub-construction.

The Ariane truss is a new timber system for industrial and agricultural buildings of large spans from 15 to 55 metres. It is based on the use of raw planks, which are put together in layers to produce a truss reinforced at the nodes with inserts of micro-laminated veneer plywood.
