Cromar Leadax Lead Substitute is the first lead-free flashing material that looks, dresses and performs like traditional lead. It offers the same malleability, pliability and weatherproofing capabilities as lead and zinc while providing a safer, lighter and more sustainable alternative.

Leadax can be installed in exactly the same way as traditional lead flashing and is equivalent to Code 5 lead in performance. Its lightweight design makes it easier to handle on site, with no scrap value and no risk of theft, making it a cost-effective and secure choice for roofing and construction projects.

Supplied in 6 metre rolls and available in 150mm, 300mm or 450mm widths, Leadax is suitable for a wide range of flashing applications, including abutments, chimneys, dormers and roof penetrations. It is BBA certified, non-toxic and extremely durable, with a working temperature range from -15°C to +100°C.

Manufactured as a circular, sustainable material, Leadax provides the performance of lead without compromising on safety, environmental impact or cost.
