Rib lath, also known as ribbed lath, is fabricated from galvanized or stainless steel sheets with raised ribs running lengthwise.
These ribs stiffen the metal sheet and provide a textured surface that enhances the adhesion (keying) of plaster, stucco, or cementbased materials. The ribs also increase tensile strength and rigidity, making rib lath a reliable reinforcement base for various construction finishes.
