MAC Harrywood Panels – Black Walnut

Category: Tag:


Our striking looking Harrywood (MS 14) galvanized steel siding is the outcome of significant research on prefinished steel and rigorous testing to confirm its resistance.

Like all MAC products, this siding is characterized by its quality, watertightness and weathering resistance. It is the outcome of years of research and development carried out by steel specialists and validated by the most rigorous testing.

The manufacturing process developed by MAC allows the metal to contract when subjected to extreme climatic conditions from very hot to very cold. During the shaping process, MAC technology prevents microcracking that might damage the paint.

Installation is simple and no special tools are required.
