Both of these materials are used to tightly bind cargo with utmost safety and security during transportation so that the cargo doesn’t fall out. But when you are visiting or working at a plant that works with steel strapping, the regulations there warrant the wearing of at least hand and eye protection.
Safer than Steel
Steel strapping requires these safety measures that allow one to be safe and secure when handling cargo and wrapping it with steel strapping. Cases where people have suffered from serious injuries from loosened steel strapping are not entirely unheard of. The razor sharp steel strapping can come loose if not handled carefully and it can cause serious damage to one’s hand’s if not handled properly.
Polyester strapping, on the other hand, can bear similar amounts of tension as its steel counterpart, but it is not very likely that it will cause any serious injuries and similar problems if it comes loose. That’s right, there is a significantly lesser risk of injury to one’s body when dealing with polyester instead of steel strapping.
This is why polyester strapping is now more common than steel strapping with many people in the business. It’s important for a business to be able to keep their employees safe and the packaging industry is no different. If polyester strapping allows employees to have a safer environment as compared to if they work with steel, it only seems logical to make the switch from steel to polyester.
Ease of Application
Polyester is superior to steel when it comes to tensioning. Steel has to have two separate tools for the process of tensioning whereas polyester requires only one. The reason, that steel requires these two tools for tensioning, is that it is a comparatively inflexible material as compared to polyester.
Additionally, the metal on metal wear and tear causes the maintenance of the steel strapping and tensioning tools to be way higher than the single tool used for polyester strapping tensioning. The strapping made of polyester can be applied easily with that single tool for a number of years. This makes it fast and easy to apply polyester strapping as compared to steel.
Strength is Not an Issue with Polyester
It may come as a surprise but polyester is just as strong as steel when it comes to the strapping application. If you were to test two bundles wrapped in each kind of strapping and drop them from a height of two feet, using a forklift, the results will leave you shocked if you doubted the strength and durability of polyester strapping.
When the bundles are wrapped in the two separate materials, it becomes apparent that the two types of strapping behave differently. Steel definitely has less elasticity when compared to polyester, which means that it can break really easily. Lane changes, stops and other scenarios in real life may cause steel stretching and possible breakage.
Additionally, the crimp of the steel strapping may be weaker that linear strength, contributing towards any breakages. The polyester strap, on the other hand, can move about and hold the cargo without being deformed or bent, helping it hold a cargo load more firmly.
Resistance to Damage
When a cargo load is being carried in a rail car, ship or even a truck, it can cause strapping to move about. Steel Strappings used on powder coated or galvanized products may be scratched and damaged. This causes an increase in the cost to the supplier which in turn increases the burden of financial costs and of time on the final customer.
Polyester straps do not have such an effect on powder coatings or galvanized products, which saves time as well as money for the end customer. Polyester is easy to dispose of than steel strapping as an added advantage.
