The XHD lintels are designed for use in very high loading scenarios. To achieve the figures in the table, the lintel must be fully bearing across its section. This is usually achieved by bearing onto the brickwork reveal. The lintel also requires a minimum bearing length of 200mm to achieve these loads due to the high compressive forces that will be applied onto the brickwork below.
The Leaf Lintel range is designed to carry a single leaf of masonry, typically the external leaf of a cavity wall. The lintel should be propped during construction to achieve the safe working load capacities declared in the design tables below. A separate DPC is required above the lintel. Wall ties should be installed within 300mm of the lintel at a maximum of 450mm centres to ensure that the masonry carried by the lintel is restrained and any potential overturning and deflection is minimised.
The standard lintel range is supplied in 150mm incremental lengths. Lintels of alternative lengths and load capacities outside of the details provided in the tables below can be designed and supplied to meet with project specific requirements. Lintels should be selected to ensure that a minimum of 150mm* bearing either side of the opening is always achieved.
