High-Strength Flat Tempered Glass for Buildings

Flat Tempered Glass (also known as flat toughened glass) is a high-strength safety glass redefining durability, safety, and adaptability in modern architecture and daily scenarios—evolving from "specialized" to "mainstream" by solving traditional annealed glass’ flaws: low impact resistance, high shattering risk, and limited tolerance to extreme conditions. Its core edge lies in the controlled thermal tempering process: flat glass sheets are heated to 620–650°C (near melting point) then rapidly cooled with high-pressure air, creating compressive stress on the surface and tensile stress inside—forming a structure that boosts strength by 3–5x vs. annealed glass. This delivers a service life of 15–20 years (2x longer than standard glass) while excelling in four key areas: Superior mechanical strength (withstands impact from 1kg steel ball dropped from 2m without breaking, vs. 0.5m for annealed glass; resists wind loads up to 2.4kPa, ideal for high-rise facades; bears surface pressure of…
