4mm Ultra Clear Tempered Glass

Aohong Glass is an ISO9001-certified manufacturer specializing in high-performance 4mm Ultra Clear Tempered Glass. Using premium low-iron float glass and advanced thermal tempering technology, we deliver exceptional optical clarity, superior mechanical strength, and reliable safety performance for architectural, interior, furniture, and industrial applications.

Compared with standard clear glass, our low-iron formulation significantly reduces the green tint caused by iron oxide impurities, ensuring superior daylight transmission, a clean aesthetic, and accurate color reproduction. Backed by state-of-the-art processing and strict quality controls, we provide precision fabrication and export-grade packaging for global wholesalers, contractors, and brand manufacturers.

Maximum Light Transmission
Features an ultra-low iron composition that eliminates the green edge tint common in standard glass, delivering up to 91% light transmission and crystal-clear visual aesthetics.
Superior Color Accuracy
Provides true, natural color reproduction, making it the ideal material for high-end display cases, retail showcases, and museum exhibits.
Enhanced Strength & Safety
Undergoes precise thermal tempering (heating to 620–700°C and rapid cooling) to achieve roughly 4 times the mechanical strength of standard annealed glass.

Reliable Fracture Performance
Complies with major international safety glazing standards (EN12150, ASTM C1048), breaking into small, blunt-edged granular pieces upon impact to minimize injury risks.

Architectural & Interior Design
Lightweight office doors, modern interior glass partitions, and hotel architectural features.
Furniture Manufacturing
Glass tabletops, decorative shelving units, cabinet doors, and furniture inserts.
Retail & Display Cases
High-end commercial display counters, retail showcases, and museum artifact display shields.
Bathroom Enclosures
Contemporary glass shower doors, bath partitions, and screen panels.

Our operational workflow ensures consistent quality from raw material to final delivery:
Low-Iron Sourcing
Selecting float glass with minimal iron oxide content to eliminate optical distortion.
Precision Cutting
Utilizing advanced CNC machinery to match exact CAD dimensions.
Edge Processing
Professional grinding and polishing prior to tempering to eliminate micro-cracks.
Thermal Tempering
Heating glass followed by rapid air-quenching to lock in high surface compression.
Quality Inspection
Comprehensive checks on dimensions, thickness, surface defects, and optical clarity.

Cutting & Shaping
Custom sizes and complex CNC profiles.
Edge Finishing
Flat, pencil, and beveled polished edges.
Holes & Cutouts
Standard holes, countersinks, and notches.
Surface Modification
Silk-screen ceramic printing and sandblasting/frosted designs.
