Resin sheets are a new type of eco-friendly, light-transmitting composite material that can replace glass or acrylic. In sheet metal processing, its extremely light weight (only half that of glass), excellent impact resistance (dozens of times that of ordinary glass), and superior cold-working properties similar to metal make it a key material in modern industrial design for achieving "metal-like processing" while maintaining light transmission and safety characteristics. Its core advantage lies in its ability to be cut, drilled, hot-bent, and riveted like metal, while solving the pain points of traditional brittle materials being fragile and difficult to process.
