Tools for Steel Strapping

Function of Strapping Tools:  Hand tools are commonly used to effectively apply steel strapping to loads of lumber, steel, bricks, blocks, and other products.  Strapping must be tensioned, sealed and cut.  In two tool operations, the tensioner tensions or tightens the strap while the sealer makes a notch or crimp to secure the tensioned strap. Cutting is done by a conventional strap cutter or by bending the strapping back over the seal, after sealing is completed.  Combination tools perform all three functions with one convenient tool, which can be manually, or pneumatically powered.

To select the correct strapping tools, you need to determine the strapping type and application:  It is also important to know the strap width and thickness.

Strap Types:  Steel Strapping is commonly available in two types, Regular Duty and High Tensile.  Regular Duty strap is made from lower PSI steel, and has essentially zero elongation.  High Tensile strap is made from high carbon steel, which is heat treated to improve its elongation and break strength.  Loads requiring very high tension or which are subject to severe jolts will typically use high tensile strapping.

Strapping Applications:  Most strapping applications can be categorized as either "conventional" or "pusher". Conventional applications are the most common.  Ideally the tool rests on a relatively flat surface and the base of the tool is actually tensioned to the load.  Due to the flat surface of the load, the tool is easily removed once the strapping is sealed, without sacrificing strap tension.  Pusher applications occur when the load is round (cylindrical) or has a small surface, which does not allow a conventional tensioner to fit between the strap and load.  Pusher style tensioners utilize a pusher seal.  The seal is an integral part of the sealing process.  The strap is pushed against the seal while  the strap is tensioned.
