GALVANIZED BUCKLES


For the quality of Buckles, it is important that:

  • they are flat and rectangular
  • the steel wire is strong enough
  • the legs are long enough not to be pulled through the base
  • the strapping can be tensioned straight
  • the construction of the crossing is strong enough
  • the slanted leg is used as the tension site

Many suppliers:

  • do not use the linear test, but the system test to only obtain a higher value
  • give a tensile strength of their buckles which is meaningless, after all it is the combination of strapping with the right buckle that determines
  • use a to small diameter steel wire and deliver a lower number per box to achieve a lower pric
  • do not measure tensile strengths and do not pay attention to the quality

There are no standards for strapping and buckles in Europe. Because of the importance of safety and the prevention of damage, Veltkamp uses the American standard ASTM 3950 during production. This indicates that the combination of strapping with buckle in a lineair tensile test must achieve a tensile strength of at least 55% of the tensile strength of the strapping. Veltkamp checks and tests on this constantly during production. The buckles in combination with the strapping are therefore also certified by DNVGL.
