Lead glass screen manufacturers

The most critical specification is the Lead Equivalent (Pb Eq), typically ranging from 0.5mmPb to 3.0mmPb depending on the radiation source (X-ray, CT, or Gamma). You must ensure the glass transparency exceeds 85% to maintain clear visibility for operators. Additionally, for mobile screens, the frame material should be medical-grade stainless steel or powder-coated steel to ensure durability and ease of sterilization.

Suppliers should provide certification for IEC 61331-2:2014 (Protective devices against diagnostic medical X-radiation). For the European market, CE Marking is mandatory, while the US market requires FDA registration. Ensure the manufacturer holds an ISO 13485 certification, which specifically governs quality management systems for medical devices.

Request a Third-Party Radiation Shielding Test Report from the supplier. You should also ask for a Material Safety Data Sheet (MSDS) for the lead glass component. For high-value orders, it is advisable to hire an inspection agency to perform a non-destructive test (NDT) using a radiation meter to confirm there are no 'leaks' or bubbles in the glass that could compromise safety.

Mobile screens must be equipped with heavy-duty, medical-grade lockable casters to prevent accidental movement during procedures. The center of gravity should be low to prevent tipping, and the handle design should be ergonomic. For fixed installations, ensure the overlap between the lead glass and the lead-lined frame is at least 10-15mm to prevent radiation leakage at the seams.

The primary risk is structural breakage due to the high density and brittleness of lead glass. You must mandate customized fumigated wooden crate packaging with internal shock-absorbing foam and vacuum sealing. Ensure the shipment is marked with 'Fragile' and 'Heavy' icons, and always purchase All-Risk Marine Insurance to cover potential transit damage.

Start by requesting a sample of the lead glass (e.g., a 10x10cm block) to test density and clarity. Negotiate a staged payment plan (e.g., 30% deposit, 70% after passing a pre-shipment inspection). Use the Audit Reports available on Made-in-China.com to verify if the supplier is a 'Diamond Member' or a 'Gold Member' with a verified manufacturing facility.

Lead is a heavy metal and may be subject to environmental regulations in the destination country. Verify the HS Code (typically 7007.19 or 7013.99) with your local customs broker to determine import duties. Due to the extreme weight, Sea Freight (LCL or FCL) is the most economical method, but ensure the floor loading capacity of the delivery vehicle and the final installation site is sufficient.
