PC H-profiles (also known as H-shaped joining profiles) are vertical connection fittings specifically designed for multi-layer hollow or solid polycarbonate (PC) sheets. Their "H"-shaped cross-section is primarily used for vertical joints between two panels. They not only secure and connect the panels but also ensure a watertight seal at the joint, preventing water leaks. Their translucent material allows them to blend seamlessly with the panels, maintaining the overall aesthetic of the lighting area.
