A lintel should have sufficient strength and stiffness and be made of a material that is compatible with the masonry it supports. Bi fold doors are a different story. Because of how a bi fold door opens and shuts even the slightest deflection in the lintel above can render the door unusable because it simply won t slide open or shut. To this end we recommend a heavy duty or even a rolled steel lintel above a bi fold door to ensure that there is absolutely no deflection.

The lintellift system fixes this issue by adding support underneath the sagging lintel. These are concrete blocks reinforced with steel rebar that sit above windows doors and any gaps in the bricks. The lintellift system is a patented product that ensures garage door lintels or headers won t sag. The lintels act as weight supporting bridges allowing the contractors to place bricks above a large gap.

Spanning an opening of 2800mm with a rise of 1200mm it will create a striking architectural feature on this project. When a garage door lintel fails it causes the brick wall being supported to sag leaving a noticeable crack right above the garage door. A lintel is a structural support over an opening allowing loads to be transferred to the foundations without unnecessary stress placed upon frames such as windows or doors. Lintels can be precast or made on site to the exact dimensions required.
