Grain tarps are used for temporary grain storage on farms or grain handling sites. They are designed to prevent damage from moisture, pests, and other environmental factors while also providing a sealed environment for fumigation. They are also commonly used to cover and protect stored crops, such as canola, almonds, corn, soybeans and many more. They are typically made from durable materials such as polyethylene, polypropylene or polyvinyl canvas (PVC).
