Details

The Keystone CFS/K-70 WIL 1800mm lintel is an extra heavy duty steel support designed specifically for cavity wall constructions with wide inner leaves. Trusted by builders and contractors, it provides dependable strength for openings in walls where cavity widths range between 70 and 85mm. This lintel is a practical choice for site managers requiring robust structural components that comply with rigorous load demands. Please note, the inner leaf blockwork should not exceed a 25mm overhang on the lintel flange to maintain performance standards.

Application

This lintel is ideal for use in cavity walls featuring a 125-150mm wide inner leaf, commonly found in residential and commercial masonry projects. It supports door and window openings where extra heavy duty load capacity is critical. For efficient construction, it is recommended that lintels are propped to speed up the build process and ensure structural integrity. The blockwork should be constructed tightly against the inner face of the lintel, with a mortar bed applied atop the blockwork before laying floor units to evenly distribute loads.
