3 Critical Pain Points When Sourcing 4 mm Clear Float Glass from China
❌ High MOQs & Inflexible Pricing
Many suppliers enforce MOQs of 10+ containers, locking SMEs out of competitive pricing. SHAHE SHOTT offers MOQs as low as 1 container with volume discounts.
❌ Inconsistent Quality & Defects
Substandard float glass often has bubbles, waves, or poor flatness. Our GB15763.2-2005 certified production ensures ≤0.3% defect rate.
❌ Long Lead Times (60-90 Days)
Traditional suppliers take months. With 3 plants and 45m tempering furnaces, we deliver in 30-45 days.
