Wide Inner Leaf Steel Lintels

Wide inner leaf (WIL) steel lintels are specifically designed and manufactured with an inner leaf able to support blockwork up to 150mm. Like their standard counterparts ‘WILs’ can support masonry loads, uniformly distributed timber floor loads, and uniformly distributed roof loads, again for roof loads an HD (heavy duty) type is required.

As with all of our steel lintels, wide inner leaf lintels are easy to install and have a galvanised finish. They also offer thermal efficiency. WILs are available in six cavity width increments – 50mm, 70mm, 90mm, 110mm, 130mm and 150mm. Each type has HD, XHD (extra heavy duty) and CXHD (composite extra heavy duty) variants, please see our steel lintel load tables for more information.

All of our steel lintels are available at various lengths starting at 600mm. For more information on wide inner leaf steel lintel sizes and prices please download the brochure section below. For the full brochure you can download it from our downloads page.
