Birtley - Why do we galvanize our lintels after fabrication?

November 2020

It’s a question we get asked a lot, why do we galvanize our lintels after fabrication? Well, there’s a simple answer.

We do it because we want to know that each and every one of our lintels leaves our factory ready to stand the test of time, in even the most corrosive of environments.

We manufacture all of our lintels by cutting and bending steel, but unlike others, we then use our in-house galvanizing facility to seal and protect the underlying steel from the elements.

Without this additional layer of zinc protection, any cuts or welds would be exposed to the elements and corrosion.

Our unique manufacturing process allows us to offer a quality controlled product that will last the lifetime of the building.
