Original Steel profile

Timeless & minimalist design | internal and external steel doors

The original slender steel profile has its origins in steel framed windows. Initially introduced in 1912. By British company “The Crittall Manufacturing Co. Ltd”. 

Since then Original Steel has been updated. And much advanced. Replicating the slender design. And now can accept double glazed units. Due to its simple and slim design Original Steel is often used in listed and heritage buildings. As well as contemporary projects.

Uniquely, this timeless door and window offers slim sight lines. Boasting great thermal and acoustic performance. Offering comfort as well as safety.

The slim profile makes Original Steel an excellent choice for both internal and external steel doors.
