Float glass 5 mm clear

Description

1. Product Overview
This is annealed clear float glass manufactured to 5 mm nominal thickness via the floating molten tin process, ensuring parallel surfaces and uniform flatness. It is primarily used in building fenestration, interior partitions, furniture, and secondary processing (tempering, laminating, coating). The key value proposition is its exceptional visual quality and mechanical predictability, enabling high-yield cutting and fabrication. Strategically, it remains the baseline flat-glass standard for global construction and OEM glazing supply chains.

2. Key Specifications & Technical Characteristics

• Chemical composition: Soda-lime-silica (SiO₂ 72–74%, Na₂O 13–14%, CaO 8–10%, MgO 3–5%)

• Purity level/grade: Commercial clear / no visible seeds, knots, or blisters per ASTM C1036, Class 1 (transparent)

• Physical characteristics:

  • Thickness: 5 mm ±0.2 mm

  • Light transmittance (visible): ≥89% (550 nm)

  • Density: 2,500 kg/m³

  • Surface flatness: ≤0.2 mm per meter deviation

  • Form: Rigid sheet, jumbo size up to 3210 × 6000 mm

• Packaging options: Interleaved paper or micro-silica powder between sheets; export wooden crates (A-grade plywood, fumigated) or stillages for repeat orders

• Shelf life: Indefinite if stored in dry, vertical racking; no chemical degradation

3. Core Industrial Applications

• Primary industries: Commercial construction, furniture manufacturing, automotive (side glazing), solar panel glass bases, display shelving

• Specific use cases:

  • Fixed windows and shopfronts in low-wind-load buildings

  • Table tops and cabinet doors in furniture production

  • Substrate for low-E coating or laminated safety glass (PVB interlayer)

• Why it performs better: Lower internal stress than 4 mm options for larger panels; higher yield during CNC cutting due to minimal edge chipping vs. 6 mm for non-load-bearing uses

• Efficiency/cost advantage: 8–10% lighter per m² than 6 mm, reducing shipping costs and handling fatigue while maintaining optical flatness superior to 4 mm drawn sheet glass

4. Competitive Advantages

• Quality consistency: Real-time online flatness and inclusion detection; each batch certified with dimensional and transmission report

• Supply reliability: Dual sourcing from two float lines (EU and MENA) with 98% on-time-in-full track record

• Logistics capability: Pre-slung crates for direct container loading; 20 FCL and 40 HQ scheduling within 7 days ex-plant

• Price competitiveness: Long-term silica sand and soda ash hedging contracts – prices fixed quarterly for contract buyers

• Sustainability: ≥32% recycled cullet content; production powered by natural gas with SCR system (NOx <400 mg/Nm³)

• Technical support: CAD-ready cutting diagrams and breakage analysis provided pre-shipment

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 20 MT (mixable with 3 mm, 4 mm, or 6 mm clear float within same container)

• Bulk 20 MT loading capacity per 20 ft container: Approximately 20 MT (stacked in 2–3 crates, depending on sheet size)
