1. Tempered Glass vs. Toughened Glass Price: 2024 Market Overview
Both “tempered glass” and “toughened glass” refer to the same thermal processing technology, producing glass that is up to 5 times stronger than standard annealed glass. With surging infrastructure projects and safety requirements, international tempered glass price indices show a consistently upward trend, notably for large custom sheets (custom tempered glass) and high-thickness options like 10mm toughened glass. China, India, and Southeast Asia lead production, with technology advances narrowing regional price gaps, but certifications, raw material costs, and energy prices still contribute to price differentials.

2. Process Flow: Clear Float Flat Tempered Glass Manufacturing
The Clear float flat tempered glass manufacturing process integrates advanced float glass and tempering technology to ensure outstanding strength, transparency, and safety. Here is a stepwise technical overview for those evaluating **tempered glass price** and quality:
Raw Material Melting
Silica sand, soda ash, and lime are melted at 1550°C.
(Ensures clarity & purity of base glass)
Float Process
Molten glass floats on molten tin, forming a uniform flat sheet with precise thickness.
CNC Cutting/Shaping
Automated CNC machines cut to required size/shape with edge polishing for safety compliance (EN12150).
Thermal Tempering
Sheets rapidly heat to ~650°C, then air-quenched, producing compressive surface stress & 5x strength.
(ANSI Z97.1, ISO 12543 standards)
Quality Inspection
ISO/EN/SGS/FDA testing: Fragmentation, flatness, surface flaw, and optical clarity checks.
