About Catnic

​

Catnic has pioneered the steel lintel for five generations. Our signature products are manufactured with a unique duplex corrosion protection system, an integral plaster key and built-in damp proof course with continuous insulation, making them the most distinctive lintel on the market.

​

What is the role of steel lintels?

​

Steel lintels are an essential component of building fabric specification. They span structural openings, providing support to the wall construction above.

​

As well as ‘standard’ steel lintels with corrosion protection, stainless steel lintels are available for installation in particular circumstances. Where a building is situated in an aggressive environment, or exceeds three storeys in height and is located in a non-aggressive environment, stainless steel offers additional corrosion protection to ensure the longevity of the lintel.

​

A range of lintel accessories is also available to help deliver the best steel lintel installation possible. Weep vents remove water from wall cavities and stop ends help to eliminate issues related to moisture penetration. Arch centres aid brick arch construction, and external plaster keys help with the application of rendered finishes.

​

What are special steel lintels?

​

The Catnic range of special steel lintels covers around a dozen unique details where specially designed and shaped lintels can help to achieve feature brickwork. They can be specified for residential and commercial developments alike, and examples of the features available include arch lintels, curved lintels, corner lintels and bay lintels.

​

Special steel lintels manufactured by Catnic are all hot-dip galvanised for corrosion protection, removing the need for painting or maintenance on-site. Where appropriate, lintels are supplied with accessories such as support (spigot) posts and base plates. Certain lintels, such as curved lintels requiring a specific radius, can be manufactured to meet the customer’s needs.
