We provide flat and curved glass tempering across the full 1.6–19 mm range, at sizes up to 3300 × 6000 mm, producing safety glass for appliances, furniture, solar modules, and display panels. Tempering heats glass to roughly 620–680 °C and quenches it with controlled air, locking the surfaces into compression and the core into tension — the stress state that gives tempered glass its strength and its safe break pattern.
Surface compression is measured, not assumed: we achieve ≥90 MPa surface stress for fully tempered glass and ≥24 MPa for heat-strengthened glass. Uniformity is maintained by automated heating-curve control, real-time air-quench pressure monitoring, and roller-wave control, because uneven heating produces optical distortion and weak zones. Tempered glass also withstands a thermal differential of 200–300 °C, which is why it is specified for appliance, cooktop, and solar use.
