| "Well" said the Hammer to the Nail - "You're not much use without me!"
And the Nail turned to the timber and said "Will you hold me tight for a 100 years?"
And the timber replied - "Of course my darling - but don't twist or shake - I've got a long sleep ahead!"
Holding Power not just Staying Power is what is needed.
The same laws of physics which enable aeroplanes of many tons to so wonderfully lift into the air are the same ones which lift roofs off houses.
A roofing nail through plywood has staying power - the roofing won't move sideways but 1/2 inch of ply has only a holding power of around 100 Newtons. On the other hand a 2" purlin which is 4 times as thick has a holding power on a good roofing nail of 400 Newtons.
In placid, calm conditions staying power will hold a building together but in windy zones holding power is needed as well as staying power and it's needed on a large scale!
Z Nails and Cyclone Straps
Calculations are possible with our special software to determine which combination is necessary.
- A Z Nail has a holding power of 1750 Newtons, 2 of them 3500 Newtons - somewhat superior to a couple of skewed nails used to hold a rafter or truss in place.
- 4 Z Nails holds with a force of 7000 Newtons.
- A Cyclone or Hurricane Strap is good up to 10,500 Newtons.
- A Cyclone Strap and a pair of Z Nails takes the holding power to 14,000 Newtons.

Construction is never cheap - and if it is it does not last. We can assist you in relation to finance - not with our money ...
When we come to Assess your House we will also discuss finance with you. If you take a look at the form relating to Finance you will see the sort of information we will be talking to you about. Click on Finance in the Index to get to the form.
