This product is a PVC grain surface insect-proof walkway board developed by our company. It is the most ideal grain surface walkway board for bulk grain storage. It has good breathability and is not easy to slip. It will not shift when moving around, is light and convenient to lay and stack, and can effectively control the mold and spoilage of grain under the grain tread board. Because there are dense holes on the board, people walking on it are not prone to slipping, and grains will not rise up from below. It is produced using a plastic formula that is not easy to age and can be sent back to the manufacturer within ten years for recycling. No pollution to the environment, beautiful, light, durable, non-aging, non-sag.
