Tight Radius Curved Tempered Glass

Tight Radius Curved Tempered Glass is designed for applications that require a small bending radius. We define tight-radius curved glass as a radius of R1000 mm or smaller, and our current production capability can reach a minimum radius of R300 mm, depending on the glass size, thickness, and shape. This capability allows architects and designers to create compact curved forms for specialized building and interior applications. Producing small-radius bends requires precise control of heating zones, forming conditions, and quenching pressure. Our technical team uses dedicated process settings to help control optical distortion and surface stress during production. Our Tight Radius Curved Tempered Glass can achieve surface compressive stress of ≥80 MPa under Chinese requirements and ≥69 MPa for USA and Australian requirements. Its bending strength is 4–5 times that of ordinary annealed glass. It can withstand a temperature difference of up to 200°C without cracking or breaking. When the glass breaks, it forms small, relatively blunt particles, which helps reduce the risk of serious cuts.

We use specialized bending equipment for small-radius curved glass. The equipment provides controlled heating across the forming area and supports precise bending conditions. During quenching, our operators monitor the production process to maintain consistent results across the glass panel. Our Tight Radius Curved Tempered Glass is suitable for spiral staircases, curved elevator enclosures, interior partitions, custom furniture, and other applications that require compact curved profiles. These applications often require both dimensional accuracy and a clear visual appearance. We check the bending radius using precision templates and measurement equipment. After inspection, we use protective edge materials and customized wooden crates to reduce the risk of chipping or impact damage during transportation. Each panel undergoes a final quality inspection before shipment.
