System WB

The WB System is the ideal solution for reinforcements perpendicular to the grain in timber engineering.







Technical information: WB-T-16/WB-T-20

Material:carbon steel
Tensile strength:800 N/mm²
Yield strength: 640 N/mm²
Drive:headless; insertion sleeve for countersinking
Surface:zinc electroplated, blue passivated, chromium(VI)-free
Length:3000 mm, individually cut to length
Diameter:outside diameter 16 mm - core diameter 12 mm
outside diameter 20 mm - core diameter 15 mm

Application:

for reinforcements perpendicular to the grain in arched and double-pitched roof purlins, at penetrations, notchings and transverse joints.




Savings you can count on:

Saves on storage. Because of the standard length of 3000 mm you need to stock only one item.

Since the threaded bar is headless, it can be cut to exactly the required length with standard tools (metal saw or right-angle grinder)

Cost savings through time saving

The WB System can be countersunk using the special insertion sleeve. Subsequent roof assembly is not obstructed.

Because of the high tensile strength fewer bars are needed. This results in significant time savings.

Easy application without glue

Forces are transmitted solely through the thread indentations - no glue is necessary for reinforcement perpendicular to the grain.
  • the time-consuming application of adhesives is eliminated, as is cleaning the tools and waiting for curing.
  • The bars can be loaded directly after setting.
  • Consistently reliable assembly conditions
  • You don't need a licence to make the reinforcements


Planning aids; measurement principles

Comprehensive planning aids, suited to a wide range of applications, ensure easy, reliable measurements.

For special applications, our timber construction engineers will be pleased to offer help and advice on the most economical and efficient fastener systems.


Assembly tools and assembly aids

Insertion sleeves for countersinking, adapters for several drivers and a drilling system to lengthen drill bits for the easy application of the WB System.
