Naylor L-Strip lintels are suitable for use in applications where support is required for the outer or external leaf of cavity wall construction.Section 9.20. Lintels are available in lengths ranging from 600mm up to 3600mm dependent upon section depth. They are available in three depths of either 85mm, 165mm or 215mm with all depths available in a choice of galvanised or stainless steel as standard. Our range of L-Strip lintels are made from either galvanised G600 or grade 304 stainless steel for optimum corrosion protection. They are also ideally suited for use in conjunction with our Hi-Spec range of prestressed concrete lintels on the inner leaf. Our L-Strip steel lintels are suitable for 100mm or 140mm wide walls to carry brick, block or stonework and would typically be used in the outside leaf of an external cavity wall. Suitable for use with either brick or stone, our L-strip steel lintels are used to support the outer leaf of cavity wall construction and are available in galvanised or stainless steel grade 304. ![]()
