Material Grades

"Unless otherwise specified, all stainless steel quoted in this catalogue is Type 316 marine grade. Plastic products, when used for loaded applications, are generally manufactured using Nylon 6, Nylon 66, or Acetal. Non Loaded products are generally manufactured in Polypropylene.

We can advise on the suitability of plastic for various applications where a choice of material is available."

Breaking Loads are for guidance only and do not form part of any warranty. All loads are quoted assuming a straight pull using shackles to secure to test the equipment. Where the load on a buckle is not straight the strength should be reduced.

Where formulas have been used to obtain a components breaking load etc. an ultimate tensile stress has been assumed of:

1. 500N/mm2 for stainless steel 2. 300N/mm2 for aluminium 3. 350N/mm2 for carbon steel

In many tests where buckles, D rings, etc. have been pulled using webbing, failure of the webbing occurs before the buckle reaches its Breaking Load. Test data is available on request and tests can be made on customer's applications if required. Buckles are used in a variety of applications and the factor of safety for Safe Working Loads may vary. Our recommendation is that the safe working load be one fifth of the Breaking Load.
