What type of fasteners are generally used to attach polymer trim members?

Mechanical fasteners are commonly used to attach polymer trim members due to their ability to securely connect materials without compromising the integrity of the polymer. Mechanical fasteners, such as screws, bolts, and anchors, provide strong, reliable holds that can accommodate the expansion and contraction characteristics of polymer materials caused by temperature changes or moisture.

Unlike other options, mechanical fasteners do not rely on adhesives or heat, which could be less effective or even damage the polymer over time. They also allow for easier disassembly and replacement of components if necessary, further contributing to the practicality of their use in construction applications involving polymer trims.
