Metal Types Used in Commercial Corrugated Siding

Commercial corrugated metal siding is typically made from steel, aluminum, or zinc, each offering unique advantages and disadvantages. Steel is the most common due to its strength and cost-effectiveness. Aluminum offers superior corrosion resistance but is generally more expensive. Zinc, often used as a coating (Galvanized steel), provides excellent corrosion protection, particularly in harsh environments. The choice depends on the specific project requirements and budget constraints. For example, a coastal building might benefit from the superior corrosion resistance of aluminum or zinc-coated steel.

Gauge Thickness and its Impact

The gauge of the metal refers to its thickness. Thicker gauges (lower numbers, e.g., 24 gauge) are more durable and resistant to dents and damage but are also more expensive. Thinner gauges (higher numbers, e.g., 29 gauge) are lighter, easier to handle, and less costly, but they are more susceptible to damage. The optimal gauge depends on the expected environmental conditions and the building’s location. A building in a high-wind area might require a thicker gauge for increased structural integrity.

The Role of Coatings in Corrosion and Weathering Protection

Coatings significantly extend the lifespan and enhance the appearance of metal siding. Galvalume, a zinc-aluminum alloy coating, offers superior corrosion resistance compared to galvanized steel (zinc coating). Kynar, a polyvinylidene fluoride (PVDF) coating, provides excellent color retention and resistance to fading, chalking, and weathering. These coatings create a protective barrier against the elements, preventing rust and extending the life of the siding. Buildings in areas with high humidity or significant UV exposure greatly benefit from these advanced coatings.

Lifespan and Maintenance Requirements

The lifespan and maintenance requirements of metal siding vary significantly depending on the metal type and coating. Steel with a Galvalume coating can last for several decades with minimal maintenance, requiring only occasional cleaning. Aluminum siding, due to its inherent corrosion resistance, boasts even longer lifespans with similarly low maintenance. Proper maintenance, including regular cleaning and prompt repair of any damage, is essential to maximizing the lifespan of any metal siding. Neglecting maintenance can lead to premature corrosion and reduced lifespan.
