Door Lintels

Selecting the right door lintel is essential for maintaining structural integrity, particularly as door openings are often wider and may carry greater loads than standard window openings. The choice of lintel will depend on the wall type, the width of the opening, and whether the wall is loadbearing.

For external walls, cavity lintels are typically used to support both leaves of masonry while helping maintain insulation across the cavity. In solid wall construction, solid wall lintels, including steel box lintels, are commonly used depending on the span and loading conditions. Internal door openings may only require lighter-duty lintels where loads are limited.

Wider openings, such as patio and bifold doors, often require heavier-duty lintels or engineered solutions to support masonry, floor, or roof loads above. Adequate bearing at each end of the lintel is also important to overall performance and should always be considered as part of the specification.

We supply a wide range of door lintels for domestic and light commercial projects, covering common sizes and applications. If you are also comparing options for other openings, you can browse our window lintels collection.
