Details

The Keystone X/K-90 lintel is a high-performance, extreme duty steel lintel designed specifically for cavity walls with widths from 90 to 105mm. Built to support heavy structural loads, it is the reliable choice for builders, site managers, and contractors tackling demanding construction projects. Please note the lintel requires lateral restraint and is best propped during installation to achieve the specified loading capacity.

Application

This lintel is ideal for supporting large openings in cavity walls such as windows, doors, and other structural apertures where extreme loading is expected. Its robust construction makes it suitable for commercial and residential developments where strength and durability are critical. The galvanised steel flange provides added protection against corrosion, extending service life on the outer leaf of the cavity wall.
