Standard and HD Box Lintels
What to Know About Standard & HD Box Lintels
At First Fence, we do more than supply fences and gates; we provide a wide range of civil and construction materials to support your entire project. From scaffolding and sheeting to street furniture and steel lintels, we’ve got everything you need to get the job done.
Support Your Structure with Standard & HD Box Lintels
Doorways and window openings often weaken structural integrity. Our Standard and Heavy-Duty (HD) Box Lintels help prevent wall collapses by reinforcing these vulnerable areas. Designed for strength, our lintels come in various lengths and heights to suit your specific build requirements.
Standard Box Lintels
We manufacture our Standard Box Lintels using 1.6mm pre-galvanised steel to meet UK building regulations for doors and windows. These offer a reliable and regulation-compliant solution for everyday construction needs.
Available Sizes:
- Heights: 75mm, 150mm, 215mm
- Lengths: 750mm to 2700mm
Heavy-Duty (HD) Box Lintels

Use them in applications requiring extra strength or durability.
