The ratchet straps we usually say is the assembly of straps and ratchet buckles, also known as ratchet tie down . The straps part of the assemblies can be made of nylon or polyester webbing , and the working load limit should be a few hundred pounds to thousands of pounds , the width of the strap can be 1 inch to 4 inches , usually we can see hooks, loops or chain extension at both ends of the assembly .
The ratchet buckle is primary made of steel, some buckles have plastic handles, some have aluminum handles, and there is one kind of buckle called one piece ratchet buckle, the handle is steel. The steel ratcheting mechanism help to secure the load easily and efficiently.
Both nylon and polyester webbing are used to make the straps, but they have different characteristics, for shock absorption, we need nylon webbing and for tie down bulk loads we need polyester webbing straps, nylon webbing has better elongation than polyester while polyester webbing are stronger than nylon ones, in real world applications we need different straps for different situation , that is to say we need both nylon and polyester webbing straps for different needs.
Coated with suitable material, we can change the characteristics of the webbing , we can make more abrasion resistant, seal the straps to prevent corrosion, increase ultra-violet light resistance, increase or decrease coefficient of friction and more .
Of course the quality of the tie down straps is the most important characteristic, to use these straps properly and safely is a must . Now we need to find low price yet high quality straps. Your local store will probably have most straps you need, but the price to quality ratio probably will be pretty high, but this is not always true. And don’t forget the online store are the best place to find a lot of products, include tie down strap, but there is a problem, you can’t touch the real products before they got delivered, it’s almost unrealistic to have vendors to send you a sample when you only need a few straps, here we can go online to read product and service reviews of these online stores, usually you can read a blog, such as Running Tire, or specialized online opinion sites.
