Steel, blue galvanised
Application:
- For wind brace bands AT of widths 40 and 60 mm
- For rafters with widths between 60 and 100 mm
Benefits:
- Clip-on locking system for quick and easy assembly
- Easy to install even in cold weather
- Large range
- Easy retightening
- Simple measurement
- Approval of the ASSY 3.0 joist hanger screw for hardwood in accordance with ETA-11/0190 means it is also ideal for refurbishments.
Combinable components:
- Clip for connecting the ends of two wind brace bands
- Tensioner for use between two bands or for connecting to the anchor plate
- Anchor plate connection not suitable for tensioning
- Anchor plate for connecting to the rafter (60–100 mm)
- Butterfly for connecting both sides of the wind brace band (rafter width 60, 80 or 100 mm)
The ETA-15/0043 and ETA-11/0190 specifications must be observed.

Measurement example steel strapping WZ without WRB tensioning system: Assumptions: Würth steel strapping WZ 1.5 x 60 mm, connection with 12 ASSY 3.0 joist hanger screws 5.0 x 40 mm, usage class 2, load duration class: "short", load Fd = 15.0 kN Calculation: R1,d Wood: 12 pcs x 2.13 kN x 0.9/1.3 = 17.7 kN, decisive => 15.0 kN/17.7 kN = 0.85 < 1.0 R1,d Steel: 23.6 kN/1.3 = 18.15 kN | ||||||||
Note: n = number of nails at anchor point Values apply to a wood raw density of 350 kg/m³ Design values for load-bearing capacity: Wood: R,d = R,k x kmod/gm (with wood gm = 1.3) Steel: R,d = R,k/gm (with steel gm = 1.3) It should be assessed whether Würth ASSY 3.0 joist hanger screws should be installed based on the edge spacing which is to be maintained. These are guides for planning purposes. The values must be calculated for each project by authorised persons. |
