Product Details
CS Illustration

The CS Coiled Strap provides nail slots for easy installation. It can be used on the wide or narrow face of timber for light repairs or heavy-duty projects. Many straps are designed to be used back-to-back on a piece of timber without fastener interference. CS coiled straps are continuous utility straps which can be cut to length on the job site. Packaged in lightweight (about 18kg) cartons.

Material

Carbon Steel 1.3mm thick: CS18 & CS18S 

Carbon Steel 1.0mm thick: CS20

Finish

Z275 Galvanised

Features & Benefits
  • Provides maximum versatility – no need to shop for straps of a particular length
  • Made from 16G and 18G Carbon Steel
  • Z275 Galvanized for extra corrosion resistance

  1. Design Capacity is the minimum of the steel strap design tensile capacity calculated in accordance with AS/ NZS 4600 and the structural joint design capacity using the applicable the k modification factors following NZS 3603.
  2. The Strength Reduction Factor φ) is 0.80 for nails in lateral loading.
  3. Duration of Load Factor (k1) is as shown. Reduce Duration of Load Factor where applicable. Capacities may not be increased.
  4. Timber species for joint design is seasoned Radiata Pine, which is New Zealand Joint Group J5 per NZS 3603 Table 4.1.
  5. Use half of the required nails in each member being connected to achieve the listed loads.
  6. Calculate the connector value for a reduced number of nails as follows: Design capacities = (No. of nails used)/ (No. of nails in table) X table load
  7. Tension loads apply for uplift when installed vertically.
