Steel Versus Polyester Strapping

Steel Strapping

Steel strapping is the process of using thick steel-reinforced bands to secure a load to a pallet or other carrier. Steel straps have a long and reliable track record for cargo reinforcement, and can be easily applied using a specially designed tensioner or similar piece of equipment.

Characteristics of Steel Straps

Steel straps are purchased in rolls and are usually half an inch to three-quarters of an inch wide and approximately an eighth of an inch thick. They are commonly found in grades of regular duty and high tensile, the latter of which is rich in carbon content and is used to bear extremely heavy loads and withstand extreme shocks. Steel straps are naturally highly durable, but are subject to rusting and can occasionally produce cuts or abrasions with their sharp edges. They are also quite heavy and expensive, with a standard roll retailing at well over one hundred dollars.

Advantage of Steel Straps

In many cases, plastic straps such as those made from polypropylene are preferable, as these are a good deal less costly and tend to be friendlier on the handler. However, plastic straps possess one crucial weakness: they are extremely susceptible to elongation. It is in this criteria that steel straps shine, for the average rate of steel elongation is a fraction of a percent for any given load, whereas plastic straps may extend as much as twenty-five percent, causing them to snap or simply dislodge their cargo.

Advantage of Polester Strap

Polyester strapping has a high break strength and is a viable alternative to steel strapping. When applied to heavy loads, polyester strap can absorb a high amount of energy without breaking and it has a higher resistance to elongation under tension than other types of strap. The strap can be applied manually or by automatic process.

Manufactured from industrial textile yarn, the strap’s rounded edges will not scratch paintwork, score surfaces or damage forklift truck tyres. The edges allow it to fit smoothly around packaging contours including those of difficult or unusually shaped products.
