X ray lead pb glass manufacturers

The most critical factor is the Lead Equivalent (mm Pb), which must match the radiation output of your equipment (typically ranging from 1.5mm Pb to 3.0mm Pb for standard diagnostic rooms). You must also ensure high Light Transmittance (usually >85%) to maintain clear visibility for medical staff. Additionally, verify the density, which should typically be around 4.36 g/cm³ or higher for high-quality protective glass.

Suppliers must provide certifications such as IEC 61331-2:2014 (International standard for radiation protection glass) or ISO 13485 for medical device quality management. For the US market, FDA registration is essential, while the CE Mark is mandatory for the European Union. Always request a Radiation Protection Test Report from a third-party laboratory to validate the stated lead equivalence.

Request confirmation that the glass is free from bubbles, inclusions, or surface scratches, as these defects can compromise radiation shielding and visual clarity. High-quality lead glass should have a uniform yellowish tint (due to high lead oxide content) but remain perfectly transparent. Ask the supplier about their polishing process and if they offer custom cutting services with finished, beveled edges to prevent chipping during installation.

10mm to 12mm thickness (approx. 2.0mm Pb) is standard for X-ray diagnostic rooms and CT scan control booths. Thicker glass, such as 20mm or more, is required for high-energy environments like PET-CT or radiotherapy suites. For industrial non-destructive testing (NDT), the lead equivalent may need to be significantly higher depending on the KV of the radiation source.

The primary risk is physical breakage due to the glass's high density and brittleness. You must mandate vacuum-sealed moisture-proof packaging and reinforced wooden crate enclosures with shock-absorbing materials. Ensure the supplier uses Fumigated Solid Wood to comply with international shipping regulations and includes 'Fragile' and 'This Side Up' labels in multiple languages.

Utilize secure payment methods and consider Third-Party Factory Audits before placing bulk orders. On platforms like Made-in-China.com, prioritize Audited Suppliers who have undergone onsite verification. Requesting a small material sample first is a cost-effective way to test the glass density and clarity before committing to a full-sized observation window.

Lead glass is heavy; therefore, Sea Freight is the most economical option, though it requires longer lead times (30-45 days). Negotiate CIF (Cost, Insurance, and Freight) terms to ensure the supplier handles the insurance for transit damage. Clarify the production lead time, which usually takes 7-15 days for custom-cut sizes, and ensure the contract includes a replacement clause for any items damaged during arrival.
