Grain Storage Cover

The Grain Storage Cover manufactured by DERFLEX is a heavy-duty waterproof PVC coated tarpaulin used to protect agricultural grains such as wheat, corn, rice, soybeans, barley, oats, and sorghum during outdoor storage. Farmers, grain depots, silo facilities, logistics companies, and agricultural exporters rely on these covers to prevent moisture, sunlight, mold, pests, and contamination during open-field grain pile storage.

DERFLEX has more than 20 years of experience supplying grain protection tarpaulins worldwide. Our PVC-coated grain storage cover is engineered for harsh weather conditions, offering long-lasting durability, UV stability, and excellent waterproofing—making it ideal for long-term agricultural storage and export operations.

Product Introduction

A Grain Storage Cover is a specialized tarpaulin designed to create a protective barrier over open-air grain piles. The material is made from high-strength polyester scrim coated with PVC on both sides, forming a robust, tear-resistant, and weatherproof cover. It prevents water penetration, blocks harmful UV rays, reduces mold formation, and helps maintain grain quality and market value.

DERFLEX ensures every grain cover meets international agricultural storage standards. With customizable thickness, GSM, width, and color, the tarp fits large industrial grain piles, bunker silos, and outdoor stockpiles commonly used in farming regions and export terminals.
