Clear Annealed Float Glass: Technical Specifications & Performance Data
Clear annealed float glass is the foundational material for virtually all processed glass products. Unlike tempered or laminated glass, it undergoes no thermal or chemical strengthening, making it ideal for secondary fabrication (cutting, drilling, edgework, etc.).

Core Advantages of Shahe Shott’s Clear Annealed Float Glass
✅ Precision Thickness Control
Our float lines maintain ±0.1mm tolerance across 2mm–25mm thickness, ensuring consistency for laminated, insulated, and coated glass production.
✅ High Optical Clarity
With ≥89% light transmittance (3mm), our glass delivers unparalleled clarity for display cases, museum glazing, and precision optics.
✅ Edge Quality & Flatness
Double-edge grinding and 0.2mm flatness tolerance eliminate distortion in large-format panels for furniture, partitions, and automotive glazing.
✅ Custom Surface Finishes
Available in frosted, patterned, acid-etched, and mirror-backed variants for architectural and decorative applications.
✅ Bulk & JIT Supply
Stock 500+ tons/month with just-in-time (JIT) delivery for high-volume OEMs in electronics, solar, and construction.
Real-World Applications: Where Clear Annealed Float Glass Shines
1. Architectural Glazing & Facades
Modern buildings demand large, distortion-free glass panels for energy efficiency and aesthetics. Our 6mm–19mm clear annealed float glass is used in:
- Curtain walls (e.g., Shanghai Tower, Dubai Marina projects)
- Skylights & atriums (e.g., Apple Park, Cupertino)
- Glass railings & balustrades (meets EN 12600 safety standards)
2. Automotive & Transportation
Used as base material for tempered, laminated, and coated glass in vehicles:
- Side windows & rear screens (meets ECE R43 safety regulations)
- Sunroofs & panoramic roofs (low-iron variants for premium vehicles)
- Railway carriage glazing (high-strength, vandal-resistant)
3. Electronics & Appliances
Clear annealed float glass is the substrate for:
- Touchscreen displays (e.g., industrial HMI panels)
- Oven & microwave doors (thermal shock-resistant)
- LED TV & monitor backlights (ultra-thin 2mm variants)
4. Solar Energy
Ultra-clear float glass (transmittance ≥91%) is essential for photovoltaic panels, where even 1% loss in clarity = 2% drop in energy yield.
🔍 Buyer’s Tip:
For solar applications, specify low-iron content (≤0.03% Fe₂O₃) to maximize light transmission. Our ultra-clear float glass meets this requirement with ≤0.02% iron oxide.

Frequently Asked Questions (FAQ) About Clear Annealed Float Glass
1. What is the difference between annealed and tempered glass?
Annealed float glass is cooled slowly to relieve internal stresses, making it cuttable and drillable. Tempered glass is heated and rapidly cooled for 4–5x strength but cannot be reworked.
💡 Use Case: Choose annealed for secondary fabrication (e.g., furniture, displays); tempered for safety-critical applications (e.g., shower doors, car windows).
2. Can you supply custom-cut glass panels?
Yes! We offer:
- Precision cutting (±0.2mm tolerance)
- Edgework: Seamed, polished, or double-ground
- Drilling & notching (for fixtures)
- Waterjet cutting (for complex shapes)
📏 Minimum order: 500 kg (or 50 sheets for stock sizes).
3. What is the lead time for clear annealed float glass?
Standard stock: 7–15 days (3mm–12mm thickness).
Custom orders (tempering, laminating, etc.): 15–25 days.
🚀 Urgent orders: Contact our 24-hour hotline (+86 152 0329 0561) for same-week dispatch.
4. Do you offer samples?
Yes! Free samples (300×300mm) available for qualification testing. No MOQ.
📦 Delivery: 5–7 days worldwide (DHL/FedEx).
5. What payment terms do you accept?
Flexible options:
- TT (Telegraphic Transfer): 30% deposit, 70% before shipment
- LC (Letter of Credit): For high-value orders
- PayPal: For samples & small orders
- Western Union: For urgent payments
