Steel coils can be some of the toughest freight to haul because their massive weight is concentrated in one small area on the trailer — not to mention their tendency to roll. While properly securing coils can be challenging, the alternative could be devastating, according to Kinedyne, which says it has a better way to keep coils on the trailer where they belong.

Kinedyne’s new Coil Chock and Friction Mat combines a longer, adjustable chock, constructed from heavy-duty 1/4" ASTM A36 grade steel sheet, with a textured mat to more evenly distribute the weight of coils across the trailer and better stabilize the load in a more secure position during transport.

Coil chocks, also known as coil bunks, are often used in conjunction with 4-by-4 boards or other hardwood timbers to stabilize metal coils on flatbed trailers. The chocks are designed to be used with chains and binders to prevent the coil from rolling around or off the flatbed.

“It is crucial to use a chock to keep the coil up off the deck of the trailer to maintain stability and prevent damage to the product and trailer deck. Using timbers alone without a chock isn’t always safe or effective," says Bob Dissinger, Kinedyne director of U.S. sales. “When securing a coil with eyes crosswise or lengthwise, it must be secured in such a way as to keep the roll from rocking/rolling and being damaged. Once a coil starts moving — especially a 25,000-pound coil of steel — there is a very high probability of failure that could lead to damage and even death.”

Kinedyne's Heavy-Duty Adjustable Coil Chock is 40 inches long and 4 inches wide. It includes three bracing positions to create a more secure position for multiple sizes of coils. The increased length and bracing sizes can be used in combination with lumber and chains to properly secure a coil for transport in accordance with federal regulations.

Additionally, Kinedyne’s new Friction Mat features a rough surface, instead of a standard smooth one, to provide a better grip on coil chocks to keep them in place on the trailer. Kinedyne’s new mats are constructed of steel belting covered on both sides by recycled rubber. The steel-reinforced-interior mats are more durable and stronger than those made only of rubber. The mats are 48 inches long by 6 inches wide and ½ inch thick, which allows the entire chock to fit on the mat for more stability.
