  1. I am about to install French doors 1.3m wide x 2.0m high. I was going to use a 1.5m 75mm thick concrete lintel to place above doors the house is an old terrace house 3 floors high with roof. Is this concrete lintel sufficient or do I need a thicker lintel ?

      Hi Ben, thanks for leaving a comment.
      Please don’t use a Catnic! I would suggest a beam, but I will get the technical team to come back to you.
      Thanks.

  3. I am knocking two rooms into one to make a kitchen diner, the beam required would be supporting first floor joists and the plaster board wall between bathroom and a bedroom. Please advise as what beam to use.

  4. I am planning to extend across the whole of the back of a standard 1935 semi detached 3 bedroom house. The open span would be approximately 5 meters. Can this be achieved without a central support?

  5. Hello,
    I am creating a 1800mm wide opening in a single block interior wall which will be 1900mm high. The building is a bungalow with a bedroom above in the roof space. I would like to use a concrete lintel but I’m not sure of the thickness I will need 65mm or 140mm. Can you please advise me on this?
    Best Regards,
    John

  7. Hi,
    The structural engineer specify a UC lintel.
    However I can’t find a local supplier – I believe the Dim for that is 100 x 100 mm. ( I can be wrong)
    I would think a U2 would do – 150 x 100 mm
    Please advice

    Regards

  8. Good day,

    I am looking at installing a stacking door 3600mm x 2100mm high. It will have a masonry wall above the a hight of 700mm (cavity wall).

    Will fabricated lintels work at this span?

  9. Hi,

    I’m looking to create an opening of up to 3,0 meters for a folding sliding door or similar, can I simply use a Catnic style lintel at 3,6 meters long?

    The house type is a semi-detached townhouse (3 storeys), there’s approximately 23m² of brick and block work (minus 4x windows) above and so the lintel will be installed on a load bearing wall but not taking loading from joists.

    Thanks in advance!
