Frequently Asked Questions
Where were the Wilko Strap (Bondbeam Truss Straps) Tested?
Cyclone Testing Station, James Cook University (School of Engineering) CTS Report No: TS589. (Revision A) & TS632, TS651 & TS696.
How many Wilko Straps are needed in an average sized home (230m²)?
Depending on the size, design of the dwelling and uplift loads. Usually up to 95% Orange Label & 5% Green Label of large homes with scissors trusses and up to 100% of smaller homes for every hold down connection to bondbeam with sheet roof.
Concrete tile roofs will increase the percentages due to their weight & reduced uplift on roof truss.
Why wrap the Wilko Strap over the top?
This gives a SURE and SECURE connection with the uplift axis line in the centre of the truss and strap connection. The alternative connection uplift is generally about 20mm off the centre of the uplift axis of the struss (Unless the truss is between 2 cleats). The wrap over reduces "sheer" stress on the nails.
What was the tested failure load using double bondbeams with the 2 N16 and 1 W8 ligature?
23.8kN to 28.9kN - Orange Label. 49.5kN to 68.6kN pine MGP 12 - Green Label.
63.9Kn up to 68.6kN Hardwood (Bondbeam Failure) - Green Label
What is the allowable uplift load using 2 x N16 Bar in double bondbeam and 20mpa concrete?
18kN. Pine MGP 10 (JD5) & MGP 12 (JD4) (includes built in load factor). (1.8 Tonne). 30Kn Pine MGP 12 (JD4). 41kN Hardwood.
Can the Wilko Strap be used with N12 bars?
Yes, Engineer needs to approve if not shown on tables. See back of brochures for tables.
What is the thickness of the Wilko Strap?
It is Galvabond 38mm x 1.2mm Orange Label and 38mm x 1.9mm Green Label. This is thicker and wider than the alternative truss strap, which is commonly used in timber framed construction throughout Australia.
Is Galvabond ok to use in concrete?
Yes. As long as it remains dry during service, see back of brochure. It has been used for over 30 years in suspended concrete slab floors as bottom reinforcing. Several buildings at James Cook University, Douglas campus, have been constructed in this manner.
Why does Wilko Strap have fewer nail holes than the alternative strapping?
Multiple holes can weaken the material. Holes are 10mm in from the edge to maintain the maximum cross-sectional area of the strap to reduce the chance of failure. There are no holes below the concrete.
Could it be difficult walking Bondbeams?
Workplace Health and Safety regulations prohibit walking on the bondbeam and top plates that are over certain heights to nail or bolt trusses. However, you may bend the straps if required.
Can nailing guns be used on the Wilko Strap?
Yes. Zig Zag pattern ¬t in parallell with holes or outside edge of holes. Green Straps should be nailed through the holes provided due to the recoil of the nail tool on the light roof Truss.
What are the recommended Nails to use when installing the Wilko Strap?
Max FAP32 V5 GKN.
Why the Max FAP32 V5 or FSP 38 nails and not any other nail?
It is a (Class 3 equivalent) nail. It is a hardened Helical thread and has a 1000 hour salt spray, mechinical galvanised protective coating to AS3566.2 - 2002.
Can nails be shot through the Wilko Strap rather than the holes already punched?
Yes - in a zig-zag pattern, but not on the outer edge of the holes. Green Straps should be nailed through the holes provided due to the recoil of the nail tool on the light roof Truss.
