Extra-thick Glass
Extra thick float glass is a high-quality, optically flat glass produced directly from the float line in thicknesses up to 25 mm.
It provides excellent surface uniformity, dimensional precision, and mechanical strength, making it suitable both for premium furniture applications and as base material for laminated ballistic and architectural glass assemblies.
MTC sources extra thick float glass from certified manufacturers in Asia and Europe, ensuring optical clarity, consistency, and reliable supply.
