Corrosion of steel laths in stucco plasters is an ongoing concern. All Structa Wire Laths and Corner reinforcement products are manufactured from wire that is Class 1 hot galvanized coating to provide corrosion resistance. Class 1 (55 gsm) is the ASTM and building code standard for wire products. For added protection on our Corner products, we have upgraded the nose wire to a heavier weight of zinc. This added zinc layer serves as a sacrificial shield, undergoing corrosion in place of the base metal. The result is a prolonged lifespan and heightened corrosion resistance.
Focusing specifically on the nose wire, this added protection enhances defense against rust. Note: For optimal results, we recommend complete embedment of our products in the stucco matrix to prevent contact with carbon dioxide or moisture. The minimum cover of 1/8” stucco embedment is required.
