King Stone Super Fire Rated Concrete Lintel TYPE29 215X215 4HR

All King Stone’s concrete lintels are wet pre-cast products, using a 40 N/mm² mix. The mix includes an additive to give a very low water absorption rate, which makes the concrete lintels ideal for use below ground.

The Super Fire Rated Range is the latest range of concrete lintels that King Stone Products has introduced to meet industry requirements and ensure that King Stone is at the cutting edge of concrete lintel technology. These are the first concrete lintels to achieve 240-minute fire rating on varying sections without the need for a separate protective outer coating: documentation from a professional fire testing organisation is available to validate this performance.

King Stone’s Super Fire Rated concrete lintels are cast from a newly developed material that has enhanced thermal performance but maintains all the characteristics of normal concrete with a density of 2000 kg/m³. This revolutionary material, exclusive to King Stone, has a very low cement content (only 2%), and emits very little C02 during manufacture. The concrete lintels made from this material have flawless surfaces, are fairfaced in appearance, and do not require separate protective outer coating.

This reduces the risk of damage in handling and avoids the inconvenience and costs of on-site repairs to damaged lintel coatings. King Stone’s material for the Super Fire Rated Range is simply a one-part mix, as with all King Stone’s other concrete lintels. Completely unique!

In addition, a substantial number of the material’s ingredients come from either renewable sources or recycled products, giving the Super Fire Rated concrete lintels unprecedented green credentials. Coupled with a 4-hour fire rated resistance – guaranteed by an independent fire testing organisation – these are the ultimate fire rated concrete lintels.
