Fabricated Structural Arch System

structural brick archThe fully bonded structural brick arch system with hidden stainless steel lintels provide the most robust structural support while meeting all the requirements of Building Control. 

Structural calculations are supplied with your arch lintels allowing full compliance with current Building Regulations.  Prior to your order drawings for each arch style or span, are issued for the approval of your design engineers and advisors.  The project only moves to production when all the detail is agreed and confirmed.

When all factors such as cost, ease of handling, simple installation, quality of finish, longevity and aesthetic ‘kerb appeal’ are considered, these arches, either flat, segmental or semicircular, are seen as a more attractive solution than many others options, including brick clad concrete or thin brick slip composite alternatives.

Benefits of Bulmer Structural Brick Arch System

  • Safe and speedy installation
  • These arches are significantly lighter than precast concrete and brick fabrications of a similar length; medium spans can easily be lifted by two people
  • Each arch lintel has purpose-built lifting lugs for site handling by hand, crane or forklift
  • The brick arch is self-supporting while building in and removes the need for temporary support
  • The Steel lintel protects the brickwork from impact during transport and storage
  • The highly durable arch is fabricated traditionally from whole bricks (not slips or pistols), removing the risk of sections falling off over time
  • Bonded brickwork is structural and acts as a traditional arch even without the steel lintel
  • When fabricated as a single skin lintel there is no cold bridge between inner and outer walls
  • The single skin lintel avoids the stress between inner and outer leaf reducing the tendency for deformation or cracking of internal finishes.
  • Simple arrangements for damp proofing and cavity insulation
  • The brick soffit is fully visible and no steel is seen on the face elevation or soffit. Ideal for use with traditional box sash widows or feature arches with deep exposed soffits
  • Full structural calculations are available for every design meeting the needs of your Building Control officer

Single Skin Arch Lintels.

The most economical solution for flat & segmental arch lintels is a single skin option. The inner leaf or inner masonry (thick or solid wall construction) can be supported with a standard box lintel or precast concrete solution, whilst the outer brickwork is supported in the hidden steel lintel.

Cavity Wall Arch Lintels.

These lintels support both the inner and outer leaf on a modern cavity wall. Due to variations in design it is important to specify clearly the dimensions of the cavity wall section and the style of the frame under, behind or within the opening.

Full Drawings and Design Calculations

Our arches are designed to achieve the structural support required and to meet building regulations. Full drawings and design calculations for your structural arch lintel design are available for submission to Building Control.
