Special Steel Lintels

Stressline special steel lintels represent the pinnacle of lintel design and creativity. Whilst we have some ‘standard’ shapes, our special lintels need to be specified, so that our technical team can ensure we create the best lintel for your individual requirement.

Our innovative design solutions for special steel lintels include semi-circular arch lintels, segmental arch lintels and parabolic arch lintels as well as apex and corner lintels, splayed bay lintels, square bay lintels and much more.

To order special lintels you will have to contact our technical office with information on wall construction, structural opening, arch rise or radius and loadings information. For more details on the information you need to provide please download our special steel lintel section brochure below. For the full brochure you can download it from our downloads page.
