3 Critical Pain Points When Sourcing 4mm Clear Float Glass
Procuring 4mm clear float glass for large-scale projects often hits these roadblocks:
- Inconsistent Weight & Thickness: Variations in density (2.5 g/cm³) lead to miscalculations in structural load. 4mm clear float glass weight is 10 kg/m², but low-grade suppliers may deliver ±0.5mm deviations.
- High MOQs & Long Lead Times: Global supply chain disruptions force buyers to order 20+ tons with 60-day waits. SHAHE SHOTT offers 5-ton MOQs and 15-day express delivery from Hebei, China.
- Hidden Costs in Custom Processing: Cutting, edging, or drilling adds 20-40% to base prices. Our one-stop OEM/ODM service integrates these at factory-direct rates.
According to MarketsandMarkets, the float glass market is projected to reach $298.65 billion by 2030, driven by demand for precision and consistency — gaps we fill with ISO 9001-certified production.

Frequently Asked Questions (FAQ)
❓ What is the exact weight of 4mm clear float glass?
Answer: The standard 4mm clear float glass weight is 10 kg/m². This is calculated using the density of soda-lime glass (2.5 g/cm³) and the formula:
Weight (kg/m²) = Thickness (mm) × Density (g/cm³) × 0.1 = 4 × 2.5 × 0.1 = 10 kg/m²
For a custom size, multiply the area (m²) by 10 kg.
❓ How does the weight change if I order tempered or laminated 4mm float glass?
Answer:
- • Tempered: Weight remains ~10 kg/m² (tempering doesn’t add material).
- • Laminated (4mm + 0.38mm PVB + 4mm): ~20.76 kg/m² (adds ~0.76 kg/m² per PVB layer).
- • Coated: Negligible weight increase (<0.1 kg/m²).
❓ What is the maximum size for 4mm clear float glass?
Answer: Our standard maximum size is 3660mm × 2440mm. Larger sizes (up to 6000mm × 3300mm) are available upon request, with adjusted lead times.
❓ How much does 4mm clear float glass cost per m²?
Answer: Pricing depends on volume and customization:
| Volume | Price per m² (USD) |
|---|---|
| 1–500 m² | $6.50 |
| 501–10,000 m² | $4.20 |
| 10,000+ m² | $3.80 |
Note: Tempering adds ~$1.50/m²; laminating adds ~$2.00/m².
❓ What are the payment and delivery terms?
Answer:
- • Payment: 30% deposit, 70% before shipment (T/T, L/C, or PayPal).
- • Delivery: 15–20 days for standard orders; express (7 days) available for urgent needs.
- • Shipping: Sea freight (FOB/CIF) or air freight for samples.
