Keystone Steel Lintels

Steel Lintels

We supply both Keystone and Catnic lintels, two of the leading lintel suppliers within the UK.

We keep a large range of sizes in stock, including:

4" x 900mm up to 4800mm

Also available are "L" profile galvanised heads. Stock sizes include:

4" x  900mm to 2700mm

It is possible to have steel lintels made to a specific requirement. This is ideal for sunrooms for example where a standard size is not adequate or where an arched lintel is required. We are able to forward plans to the manufacturer on your behalf and get a quotation for any shape or size
