Hessian Fabric, also known as burlap, is a coarse, woven fabric made from natural jute or hemp fibers and is best classified under building materials and supplies, specifically as a construction support or surface protection material. It is not an adhesive or roofing material but is widely used in construction for purposes such as curing concrete (by retaining moisture), covering and protecting materials on site, erosion control, and temporary weatherproofing. Its natural, breathable, and biodegradable properties make it ideal for supporting various construction activities without being a primary structural component.
