Considering Paint Finish and Gauge Selection

When it comes to choosing the gauge for your metal roofing, it’s important to consider not only the desired strength and durability but also the impact of the paint finish on gauge selection. Two common paint systems used for metal roofing are PVDF and SMP.

PVDF, or Polyvinylidene Fluoride, paint systems are known for their exceptional durability and resistance to fading and chalking. However, it’s important to note that PVDF paint systems are typically available only in 24 gauge. This means that if you prefer the added protection and longevity offered by a PVDF finish, your gauge options may be limited.

On the other hand, SMP, or Silicone-Modified Polyester, paint systems offer an excellent balance of performance and affordability. These paint systems are available in a range of gauges, including 26 gauge. So, if you’re considering an SMP paint finish, you have more flexibility in terms of gauge selection.

The choice of paint finish also affects the color options for your metal roofing. PVDF paint systems usually offer a wider range of colors, including metallic and custom options, allowing you to achieve a more visually striking appearance.
