ventilated doors


Bradbury offer a selection of ventilated doors which are perfect for plant rooms, bin storage, and any other rooms or spaces that require ventilation and security. All are available with certification by the LPCB, from LPS 1175 SR1- SR4, and fire-rated louvres can be incorporated if necessary.

Our ventilated steel doors are a cost-effective alternative to wooden doors that are often used for plant rooms and substations. They are more robust, and, if vandalism is a risk, textured powder coating options are available, which makes removing graffiti a simple task.

If you’re looking to increase your level of security, then we have a range of other security products to suit, such as substation doors, grilles and cages.

If you’re interested in learning more about our security solutions, feel free to give us a call on +44 (0)1724 271999, or complete the contact form below so we can assist you further.

Key Features

  • Air flow
    Ventilation is provided by punched louvres on the outer skin of the door (60mm wide, protrude 5mm) and slots on the inner skin. Available solid, half or fully louvred.
  • Cost effective
    A more cost effective alternative to wooden doors, which are commonly used on plant and substations.
  • Anti-vandal
    An anti-jemmy strip and high security solid steel dog bolts provide protection for the locking system and deter against unauthorised access, as well as optional locking bar to protect external locking.
  • Easy installation
    Lightweight construction and lift off hinges provide for easier installation (manufactured to comply with lifting regulations).
  • Easy access for large machinery
    The option of a removable top sill/transom and panel provide greater access for plant machinery. An extra wide bi-parting door is also available.  
  • Re-inforced frame profile 
    Secured to the wall cavity with pre-punched fixing holes which are concealed from view. 
  • Vermin protection
    Small louvred slots on the front and slots on the back of the door prevent the entry of small animals.
  • Anti-corrosive construction
    A non-welded construction made from Zintec steel with stainless steel hinges and a hardwearing polyester powder paint finish make this door less prone to rust - an all-round durable solution.
  • Wide selection of finishes
    All doors are made from Zintec as standard and are finished with either a primer or polyester powder coating. There are 17 Bradbury Stock colours to choose from, as well as a range of other RAL and BS colours, which are available upon request. Enquire about textured and our ten year guarantee paint.
