Frequently Asked Questions
A prestressed concrete lintel is a structural concrete component used to support masonry and other specified loads above openings such as windows and doors.
During manufacture, steel tendons are tensioned before the concrete gains strength. Once the concrete has hardened sufficiently, the tension is released, introducing compression into the concrete and improving its structural performance.
Precast concrete lintels are manufactured off-site in a controlled production environment.
Prestressed concrete lintels are a type of precast lintel manufactured using tensioned steel reinforcement to improve structural performance.
All prestressed concrete lintels are precast, but not all precast concrete lintels are prestressed.
Greaney Concrete manufactures prestressed concrete lintels in a range of cross-sectional sizes and lengths to accommodate different building requirements.
The appropriate size depends on the opening span, supported loads and wall construction.
Contact our team for current product dimensions, available lengths and technical specifications.
Prestressed concrete lintels can be used in load-bearing masonry walls where the selected lintel has sufficient capacity for the specified span and loading conditions.
The correct lintel must be selected using the relevant manufacturer's technical data and structural design requirements. For projects involving significant loads or unusual conditions, advice should be sought from a qualified structural engineer.
The minimum end bearing depends on the lintel type, span, loading and supporting masonry.
Lintels must be installed with adequate bearing at both ends, in accordance with the manufacturer's specifications and the structural design.
Always confirm the required bearing before installation rather than assuming one standard measurement applies to every lintel.
Choosing the correct lintel involves considering the opening width, wall thickness, loads above the opening and the required end bearing.
Greaney Concrete can provide information on available lintel sizes and product specifications to assist with selection.
Where structural calculations or load-bearing verification are required, the final selection should be confirmed by the project engineer.
