The 3mm Plastic Unequal H Section (H Joint Trim) is a precision-designed panel joining profile for connecting 3mm wallboards, ply, and thin sheet materials while providing a neat, finished edge. Its unequal leg design helps secure panels in position while protecting vulnerable cut edges from damage.

Manufactured from rigid PVC, the 3mm Unequal H Section is lightweight, durable, and easy to cut and install, making it ideal for detailed fabrication work and thin panel applications. It is commonly used in signage, exhibitions, displays, shopfitting, vehicle fitouts, and bespoke manufacturing projects where a clean and professional finish is required.

Designed to complement matching 3mm Plastic J Sections, this H Joint Trim provides a complete edging and joining solution for lightweight boards and sheet materials, helping create durable and visually appealing installations.
