MATERIAL GRADES
Unless otherwise specified, all stainless steel quoted in teh 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 polyproplylene.

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


LOADING ASSUMPTIONS
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 the test equipment.  Where the load on a buckle is not straight the strength could be reduced.

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

500N per mm2 for stainless steel
300N per mm2 for aluminium
350N per 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 it breaking load.  Test data is available on request and tests can be made on customers 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.
