A composite material combining glass and steel, or a trade name for certain specialized glass-ceramic or reinforced materials used in industrial applications.
From 'glass' + 'steel,' a compound noun created in the 20th century as materials science developed stronger, more specialized composites.
Some glassteel products are actually glass-ceramic composites that can withstand extreme temperatures better than either pure glass or steel alone—they're used in aerospace and nuclear applications where materials face conditions Earth materials weren't designed for.
