Frequently Asked
Questions

Expert answers to common technical and commercial inquiries.

What factors influence the 4mm float glass price?

The pricing is primarily driven by raw material costs (silica sand, soda ash), energy consumption during smelting, and the specific glass grade (e.g., Ultra-Clear vs Clear). Order volume and logistics also impact final quotes.

Is 4mm float glass suitable for structural partitions?

While 4mm glass is ideal for interior dividers and furniture, we recommend laminating or tempering it for high-traffic structural partitions to ensure safety and impact resistance.

How do you ensure consistent thickness?

We use advanced molten tin bath technology and laser-guided thickness sensors that monitor the glass ribbon in real-time, ensuring a deviation of less than ±0.2mm.

What is the lead time for bulk export orders?

Standard bulk orders typically ship within 15-25 days depending on the quantity and customization requirements. Samples are usually delivered within 7 days.

Can the 4mm glass be customized in size?

Yes, we provide precise CNC cutting services to meet your exact dimensions. We also offer edge polishing and drilling services before shipment.

How is the glass packaged for international shipping?

We use reinforced wooden crates with shock-absorbing foam spacers and moisture-proof wrapping to ensure zero breakage during long-haul sea transit.
