Clement Jansen Doors

Jansen slim steel profiles create an individual look for an office or retail scheme, a new building or a restoration project.

Clement manufactures single and double doors from Jansen cold formed steel profiles which meet the latest specifications for energy efficiency, security and fire protection. These steel doors are very resilient and therefore suitable for areas of high foot fall.

The strong steel profiles mean large expanses of glazing are possible with very slender frames.
