Strapping Buckles
For the quality of Strapping Buckles, it is important that:
- they are flat and rectangular
- the steel wire is strong enough
- the legs are long enough so as not to be pulled through the base
- the strapping can be tensioned straight
- the construction of the crossing is strong enough
- the angled leg is used as the tensioning edge
Veltkamp Quality:
- in-house production of buckles which are checked daily by our QHSE department
- tensile tests are performed using the linear method and not the system method to achieve a higher value
- for optimal tensile strength, the combination of strapping with the correct buckle is essential
There are no standards for strapping and buckles in Europe. Due to the importance of safety and preventing damage, Veltkamp applies the American standard ASTM 3950 during production.
This indicates that the combination of strapping and buckle must achieve a tensile strength of at least 55% of the tensile strength of the strapping in a linear tensile test.
Veltkamp checks and tests for this during production. The buckles in combination with the strapping are therefore certified by DNV (Det Norske Veritas).
