热弯玻璃，系由平板玻璃加热软化在模具中成型，再经退火制成的曲面玻璃。热弯玻璃一般在电炉中进行加工。由于单片热弯玻璃不属于安全玻璃范畴，通常在建筑上热弯夹层玻璃的应用较多。
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.
