Hidden nail horizontal laying type rock wool sandwich panel is a type of metal-faced composite panel that connects horizontally between purlins. This panel is renowned for its elegant appearance. Installation is extremely convenient, and once installed, the entire wall surface has no exposed bolts, ensuring the wall's waterproof performance and extending the service life of the entire wall system. The surface of the horizontal laying panel features alternating small concave and convex waves, giving the entire wall a modern look after installation.
