Box Lintels
Box lintels are designed as a heavy-duty solution for use in internal solid walls. This provides strong and reliable support for openings like windows and doors. Their engineering ensures they can handle demanding load conditions, carrying materials such as masonry, floor and roof loads. Regardless of whether you’re working on residential or commercial construction projects, they can be used to help maintain a strong structure to key standards.
These lintels are made from materials like galvanised steel, with options featuring additional protective coatings that help improve corrosion resistance and long-term performance. The rigid box profile enhances further structural stability, ensuring you can install your new lintel as soon as possible for improved efficiency on site.
