Wholesale shower glass

When sourcing shower glass, safety is the absolute priority. You must ensure the glass is tempered (toughened) and meets international safety certifications such as ANSI Z97.1 (USA), EN 12150 (Europe), or AS/NZS 2208 (Australia). Always request CCC (China Compulsory Certification) marks on the glass surface and verify that the fragmentation test results show at least 60 particles per 50x50mm area to ensure it breaks into blunt pieces upon impact.

Standard thicknesses range from 6mm to 12mm. For high-end frameless designs, 10mm or 12mm is preferred for structural integrity, while 6mm or 8mm is ideal for framed or semi-frameless budget projects. To increase product competitiveness, specify Easy-Clean (Hydrophobic) coating, which reduces maintenance by repelling water and lime scale. Additionally, opting for Low-Iron glass (Ultra-Clear) eliminates the green tint found in standard clear glass, providing a premium aesthetic for luxury markets.

Shower glass is often sold as a kit or requires precise drilling for hardware. You must provide the supplier with accurate CAD drawings indicating hole positions for hinges and handles. Ensure the edge polishing is 'Flat Polish' or 'Pencil Edge' to prevent injury. If you are sourcing hardware separately, confirm that the glass thickness matches the gasket specifications of the hinges to prevent leaks or glass slippage.

Look for suppliers who use automated CNC cutting and polishing to ensure dimensional tolerances within ±1mm. Check for the absence of bubbles, scratches, or inclusions (nickel sulfide stones), which can cause spontaneous breakage. High-quality manufacturers often perform a Heat Soak Test (HST) to significantly reduce the risk of spontaneous explosion after installation, which is a critical selling point for commercial projects.

Glass is fragile and heavy. Insist on L-shaped or A-frame wooden crates made of fumigated solid wood or plywood. Each glass sheet should be separated by cork pads or plastic corner protectors. For LCL (Less than Container Load) shipments, ensure the crates are not stackable to prevent crushing. It is highly recommended to purchase Marine Insurance (All Risks) to cover potential transit damage.

Focus on volume-based pricing; glass prices are highly sensitive to raw material costs and energy prices. Request a breakdown of the price per square meter versus the cost of hardware and coating. To secure better terms, leverage the Made-in-China.com platform to compare verified manufacturers. Mentioning a long-term project pipeline rather than a one-off order can often secure a 5-10% discount or free logo sandblasting.

Ensure the supplier provides a Certificate of Compliance (CoC) matching your country's standards. You will need a Detailed Packing List, Commercial Invoice, and Bill of Lading. For certain regions, a Certificate of Origin (e.g., CO or Form E) may be required to benefit from preferential tariffs. Always check for Anti-Dumping Duties (ADD) on Chinese glass in your specific region to avoid unexpected costs at the port.

Use secure payment methods such as Letters of Credit (L/C) for large volumes or Escrow services provided by reputable B2B platforms. Avoid sending full payments upfront; a standard industry practice is a 30% deposit and 70% balance against the Bill of Lading (B/L) copy. Conduct a third-party pre-shipment inspection to verify the quantity and quality before the final payment is released.
