Learn About Metal » Minimal Maintenance
The exterior of a metal building is essentially maintenance free and long-lasting, thanks to superior, life-extending wall and roof coatings that retain color and resist dirt. Metal walls and sloped metal roofing are both self-cleaning.
Steel does not support mold growth, resists rust and decay better than other building materials
The bottom line is that low maintenance costs lead to low operating costs - a huge benefit over time.
