Built for Internal Support

The Catnic BHD100 lintel supports internal wall constructions with high load demands. It provides immediate structural support for wet masonry, removing the need for propping or delayed construction.
Its box profile adds rigidity and strength across long spans, making it ideal for solid single-leaf walls where durability and load performance are essential.

Engineered to Heavy Duty Standards

Designed to handle full masonry loads, the BHD100 lintel complies with BS EN 845-2. The heavy-duty box section resists bending, even under prolonged compressive pressure.

Resistant and Reliable

Each lintel is finished with a corrosion-resistant galvanised coating and a tough powder coat for additional durability. This duplex system extends its lifespan, even in variable site conditions.

Span and Weight Details

Lintels are available in sizes from 750mm to 4800mm. A typical 3000mm unit weighs around 30.82kg (30,820g). The staggered slots on the underside form a built-in plaster key for faster finishing.

Trusted by Builders

Produced by Catnic, a Tata Steel company, the BHD100 box lintel is the industry standard for robust and reliable wall support across internal applications.
