Fiberglass Reinforced Plastic (FRP) panels are one of the most durable, hygienic, and cost-efficient wall covering materials in industries like food processing, healthcare, and commercial kitchens. However, panels alone aren’t enough—FRP trims (including division bars, end caps, and corner trims) are essential for sealing joints, preventing water penetration, and ensuring a professional finish.
Unfortunately, many installations fail because trims are poorly fitted or incorrectly sealed, leading to moisture damage, bacterial growth, and costly repairs.
This guide will walk you through FRP trim installation cost, step-by-step methods, and common mistakes to avoid, ensuring your project is done right the first time.
