Tensioner manufacturers' production requirements for strapping are exactly in accordance with EN12195-2:2000 (European Tensioner Executive Standard). Regarding the synthetic fiber webbing part, the requirements of the tensioner principle distinguishing the number of threads are exactly the same as those required by the strapping implementation standard. The number of black threads in the finished bundle tape webbing then represents its tensile strength. So in the process of use, if the label part is damaged can not clearly indicate the ability to use, according to the number of black lines of synthetic fiber flat webbing to identify its tension, more simple, faster and more convenient. Hand-operated tensioner sets of strapping safety factor requirements in about twice, generally we say the GS certification is strictly in accordance with this standard tested, there is no specific domestic standards for strapping implemented, so that the regular manufacturers produce strapping are European standards. Safe use of strapping from the beginning of understanding.
