Application

This lintel is ideal for heavy-duty cavity wall construction, supporting large window or door openings where strength and stability are critical. It’s commonly used in residential, commercial, and industrial projects requiring reliable load distribution across cavity walls.

Propping lintels during installation is recommended to speed up construction and maintain safety.
