140 x 100 x 3300mm Concrete Prestressed Lintel Universal
The Universal Prestressed Concrete Lintel is a high-strength structural support element engineered to safely carry masonry loads over door and window openings in domestic, commercial, and industrial construction. Designed with integrated high-tensile steel strands, this lintel combines the exceptional compressive strength of concrete with superior tensile resistance, allowing it to span wide openings effectively while minimizing structural deflection under heavy loads.
Manufactured from high-grade, dense concrete enclosing pre-tensioned reinforcement, this lintel is built to endure rigorous structural demands and resist environmental degradation over decades of service. Its robust, moisture-resistant composition protects the internal steel elements from corrosion, frost damage, and weathering, ensuring long-term structural stability and reliable performance in both internal and external wall configurations.
Designed for straightforward on-site integration, the universal profile beds down easily onto brickwork or blockwork with recommended minimum bearing lengths to distribute weight evenly across the structure. Whether you are framing new residential windows, supporting internal door openings, or undertaking commercial structural alterations, this trade-quality prestressed concrete lintel delivers dependable load-bearing support alongside a secure, compliant building standard.
Available in: 100mm x 65mm & 140mm x 100mm profiles, 600mm, 900mm, 1200mm, 1500mm, 1800mm, 2100mm, 2400mm, 2700mm, 3000mm, 3300mm, 3600mm and 3900mm lengths - others available on request.
Concrete Prestressed Lintels are heavy-duty structural beams engineered with internal high-tensile steel wires that are put under tension (prestressed) before the concrete sets.
They are primarily used for:
-
Supporting Masonry Over Openings: Spanning the gap above doors, windows, and garage openings in internal or external brick and blockwork walls to carry the heavy load of the structure above.
-
Carrying Heavy Floor & Roof Loads: Supporting floor joists, concrete floor planks, and roof trusses that sit directly above door or window openings.
-
Preventing Wall Cracking & Structural Failure: Distributing vertical weight evenly down into the surrounding load-bearing walls on either side of an opening, preventing sag, masonry cracking, or wall collapse.
-
Fire-Resistant Structural Support: Providing high fire resistance in structural wall openings for residential, commercial, and industrial buildings.
