热弯玻璃是将玻璃加热至软化温度，然后靠自重或外界作用力将其弯曲成型并自然冷却后形成;弯钢化玻璃是在变曲成型后用专用设备快速风冷制成。热弯玻璃不属于安全玻璃，弯钢玻璃属于安全玻璃

弯钢玻璃是将玻璃通过预处理加工（切磨成所需尺寸）再加热到软化温度，然后靠自重或外界作用力将其弯曲成型并经自然冷却后制成所需的弧形玻璃。

Hot bending / bending steel glass is heated to the softening temperature by pre processing (cut into the required size) and then bending by self weight or external force to make the required arc glass after natural cooling.
