Plastic and Wire Buckles
The work volume, production speed required, and required strength determines closure method. For low volume, low tension applications, buckles are a good method of joining plastic strapping. This is particularly true if portability and cost are major issues. One can easily hand tension the strap, with or without the use of a hand pull or crank tensioner, and apply the buckle without the need of a power source. The metal buckles are stronger than the plastic ones and can withstand greater tensioning. Plastic buckles are used on lighter weight loads, especially in agriculture, as they can be easily hand applied in the field without the need for tools.
Phosphate finished buckles on bonded and all woven cord strapping.
Galvanized finished buckles are required for composite cord strapping
Bright finished buckles are for polypropylene strapping.
