Large amounts of materials transported from one location to another either go in a dump or flatbed truck. To protect the load but also for safety reasons, tarps are added to the truck bed. For dump trucks, a polyethylene or mesh tarp applied to the bed keeps all materials, large or small, contained, preventing them from becoming litter or hazards to motorists and pedestrians. Flatbed tarps, often made of polyethylene, are applied directly to the load and are necessary for protecting lumber and other materials from water damage. Before a tarp is applied, have the load ready on the truck bed. Flatbed tarps
need to be applied manually, and to do this, someone needs to be on top of the load to roll out the tarp. Once the tarp is rolled down the center of the load, fold it out fully. Lumber tarps have sturdy, steel D-rings on the sides, and as the material is folded out, the D-rings need to end up on the sides of the load - not on top. This position makes securing the tarp easier and safer. Bungee cords need to be put through all D-rings in order to keep the sides down. Like dump truck tarps, flatbed tarps too experience wind whip. If wind gets under the flaps, the polyethylene will wear quicker or tear. Similarly, the hooks of the bungee cords need to point outward. Otherwise, the hooks will tear into the tarp. As soon as all sides of the tarp are secured with D-rings, the load itself must be attached to the flatbed.
Flatbed truck tarps are made out of heavy duty polyethylene, although vinyl is sometimes used. Polyethylene is a highly durable material with a high denier count. It has a supremely tough weave that is strong and resilient against all kinds of pressure and weight. This fabric is also waterproof, UV resistant and flexible. Flatbed tarps will easily conform to the shape and size of the load you're transporting. Ideally, the tarp will wrap tightly around the cargo to have the best chance of acting as a protective barrier against the elements. These larger tarps need to fully fit over the load. Otherwise, wind may get under the material. Before you choose a flatbed tarp, measure the general load size first and choose a piece of material that will fully fit over all sides. Once properly secured the tarp will be snug and immovable. Even at high speeds, flatbed tarps will stay intact, protecting you goods.
