Durulite® Standard Doors are designed as a multi-purpose lightweight door, yet they are tough enough to take the abuse of personnel, stock carts and motorized pallet jacks. Like the Durulite Industrial, it's strength lies in its rotationally molded cross-linked polyethylene construction. Standard tests for impact resistance indicates that cross-linked polyethylene is 5 times more puncture resistant and 3 times more flexible than ABS material. The door is designed to comply with all USDA sanitation requirements and is NSF approved. the panel is corrosion resistant, making it ideal for washdown applications as it has no gaps or joint seams.
