Welcome to the home of Birtley SupergalvLintels

Birtley is the ONLY lintel range that guarantees complete and consistent protection. And, on top of that industry-leading performance, you’ll also enjoy the unlimited support of our entire technical team, free of charge.

Think of Birtley’s technical team as an extension of your own
Whether you’re a specifier, builder or stockist, the technical questions around lintel design and performance are becoming more and more complex – with new regulations on the way to further complicate things.

Not sure how to achieve the right result?
Then just leave it to us. Tell us what needs building, no matter how unusual, and our team will do all the number crunching. Normally we’ll turn round your lintel schedule within 48 hours. And, whenever ideas demand a custom-made solution, we’ll create that for you too.
