The UKLintels 140mm Galvanised Steel Heavy-Duty Internal Box Lintel is designed for builders and contractors requiring a robust, reliable support system for internal partition walls. It serves as a superior, lighter alternative to traditional concrete lintels, capable of handling concrete floor loads, timber joists, and roof trusses. While it offers excellent structural integrity for both load-bearing and non-load-bearing applications, users must ensure the 1800mm length is precisely measured to provide the required end bearing support for their specific structural design.

No, this product is specifically designed for internal partition walls and is not rated for exposure to external weather conditions.
A minimum end bearing of 150mm at each end is typically required; however, always defer to your project's structural drawings.
It does not require painting for protection, but it can be painted if needed, provided a suitable metal primer is used first.
Cutting steel lintels can compromise their structural integrity and should only be done if specified by a structural engineer.
While the exact weight can vary by batch, it is significantly lighter than a concrete equivalent of the same span, allowing for easier two-person handling.
Check if the specified load-bearing capacity was exceeded or if the minimum required end bearing was not achieved.
Ensure the plaster key is facing correctly and verify that the steel is free of oil or debris before applying the base coat.
If installed in a humid environment, clean the area and apply a corrosion-inhibiting primer to seal the galvanised finish.
Installation requires standard site practices for steel lintels. Always ensure a minimum end bearing of 150mm on each side of the opening unless structural calculations specify otherwise. The lintel should be leveled perfectly across the opening before proceeding with masonry work. Ensure the plaster key faces downward to facilitate the application of finishing coats. For care, simply keep the lintel dry prior to installation. If the galvanised coating is accidentally scratched during transit, apply a cold-galvanising spray to maintain long-term corrosion resistance. This product is compatible with standard cement mortars and plastering compounds.
