Extra Heavy Duty Lintel – XHD
Extra Heavy Duty (XHD) Lintels are engineered for the most demanding structural openings, where very high loads or wide spans need to be carried. Manufactured from austenitic stainless steel to Grade 304, XHD lintels must be fully bearing across their section, usually achieved by bearing onto the brickwork reveal, to reach their full design capacity.

General Guidance
The Ultimate Load Bearing Lintel
Designed for very high loading situations, XHD lintels suit small openings carrying high loads or larger clear openings requiring wide spans. To achieve the design table figures, the lintel must be fully bearing across its section – usually onto the brickwork reveal – with a minimum bearing length of 200mm to handle the high compressive forces. Available in lengths up to 4900mm, achieving a total UDL of up to 83.5kN.
Simple Specification
The Single Leaf Lintel range carries the external leaf of a cavity wall and needs a separate cavity tray above. Prop lintels during construction to achieve the safe working loads in the design tables. XHD lintels require a minimum bearing of 200mm at either end – greater than the 150mm used across the rest of the range – reflecting the higher compressive forces. Install wall ties within 300mm of the lintel at maximum 450mm centres.

FAQs
When should I specify XHD instead of C Type or L Type?
XHD lintel is the right choice for very high loading situations or wide clear spans that exceed what C Type lintels can achieve. L Type and C Type lintels suit progressively lower loads, with XHD lintels sitting above both as the highest capacity option in the range.
What loads and spans does XHD Lintel cover?
XHD lintels are available in lengths up to 4900mm, achieving a total UDL of up to 83.5kN. Capacities shown are for the lintel itself – bearing capacity checks on the brickwork below remain the responsibility of the project engineer.
