As of May 2026, Ultraray Radiation Protection holds 100 tons of high-purity lead rolls and lead sheets at its Oakville, Ontario, facility, making it the largest lead roll and sheet supplier in Canada. The milestone arrives after 40 years in business and gives healthcare builders, contractors, and industrial projects faster access to radiation shielding material at a time when construction schedules leave little room for supply delays.

How Did This Happen?
Recently, Ultraray finalized new contracts with its supply partners, allowing the company to carry a far larger on-site inventory than at any point in its history. As a result, orders now move to same-day dispatch, whether a contractor needs a single roll for a clinic retrofit or a full material package for a hospital imaging suite.
For the construction industry, the timing is significant. Material availability remains one of the most persistent risks on shielded construction projects. Imported or made-to-order lead frequently introduces lead times that stall framing, delay equipment installation, and push back inspections. By holding 100 tons of inventory locally in Oakville, Ultraray removes that bottleneck for projects across Canada and the northern United States.
Moreover, the milestone reflects four decades of continuous supply. Since 1985, Ultraray has provided shielding materials to the medical, nuclear, industrial, security, and construction sectors. Becoming the country's largest supplier is the result of that long-term market position.
High-Purity Lead Rolls and Lead Sheets
Ultraray manufactures its lead rolls and lead sheets to ASTM B749 / QQ-L-201F standards, with a verified purity of 99.9% or greater. This consistent purity directly supports dependable radiation attenuation, which is essential in regulated medical and industrial environments.
Notably, the material delivers several clear advantages:
- Superior radiation shielding helps reduce X-ray and gamma radiation exposure
- High density provides effective protection with minimal thickness
- Excellent malleability allows easy cutting, forming, and field installation
- Long-term corrosion resistance suits both interior and exterior use
- Broad compatibility integrates with drywall, plywood, doors, frames, and modular shielding systems
In addition, Ultraray stocks common, chemical, and antimonial lead grades to suit different mechanical and environmental requirements. The material ships in both panel/sheet and roll formats, with widths up to eight feet and lengths up to 25 feet. For non-standard requirements, the team also provides custom cutting and fabrication.

Reasons to Purchase From Ultraray
Beyond inventory scale, several supply terms distinguish Ultraray in the Canadian market. You can read the full breakdown in our blog post on what sets Ultraray apart from other sheet lead suppliers.
No minimum order quantity (no MOQ): Many suppliers force customers to buy more than they need and then turn them away when only a couple of extra lead rolls are needed. Ultraray has no minimums, so customers can order one roll or one hundred with no restrictions.
Buy-back on unused material: Project quantities are hard to predict. Ultraray reimburses unused lead rolls and lead sheets returned in undamaged, usable condition, providing a safety net against over-ordering.
Same-day pickup and fast shipping: For customers near Oakville, same-day in-person pickup is available once an order is confirmed. Shipments to other destinations go out as soon as the order is placed.
Free expert guidance: With over 40 years of experience, Ultraray's team helps customers confirm the right thickness, format, and quantity at no charge, by phone or in person, before an order is placed.
Certified 99.9% purity: Every order meets ASTM B749 / QQ-L-201F standards, with Certificates of Conformance (CofC) and First Articles of Inspection (FAI) available upon request for regulated procurement.
Supporting Projects Across Canada and the USA
Today, Ultraray regularly ships sheet lead for radiation protection to customers throughout Ontario, British Columbia, Alberta, Saskatchewan, Manitoba, Quebec, and Atlantic Canada, as well as across the border into the United States. Its customers include healthcare facilities, construction contractors, defense suppliers, OEM manufacturers, and research institutions.
As demand for diagnostic imaging, nuclear medicine, and industrial inspection continues to grow, dependable access to shielding materials in Canada will only become more important. With this milestone, Ultraray is positioned to meet that demand for the next 40 years and beyond.
Why Sheet Lead Remains the Standard for Radiation Protection
Even with advances in alternative shielding materials, sheet lead remains one of the most widely specified radiation protection products. The reason is simple. Lead combines proven performance, durability, and flexibility in a way that few materials match.
For example, its density delivers strong attenuation against X-ray and gamma radiation without requiring excessive wall space. Meanwhile, its malleability lets installers work around penetrations, corners, and structural framing far more easily than rigid alternatives. As a result, lead rolls and lead sheets are commonly used in:
- X-ray and fluoroscopy room shielding
- Nuclear medicine and PET imaging environments
- Industrial radiography rooms
- Mobile radiation barriers
- Lead-lined walls, doors, and frames
- Security and inspection systems
Because every project differs, Ultraray supports both large-scale installations and smaller custom orders. You can learn more about ordering lead rolls and lead sheets here.
