The Birtley Heavy Duty Cavity Lintel 50mm HD50 is the leader in heavy-duty cavity wall support options. Engineered specifically to support cavities between 50mm and 65mm with outer leaf of 100mm and inner leaf of 100mm, this 50mm heavy-duty lintel can handle the toughest demands. A solid fully jointed blockwork infill to its inner leaf ensures optimal performance. The use of structural grade steel conforming to EN10025 standards provides unparalleled strength. The lack of baseplate or factory insulation reduces thermal bridging effectively. The Supergalv coating further extends the heavy-duty lintel’s lifespan.
Features:
- More Strength: The 50mm Heavy Duty Cavity Lintel is made with structural grade steel in accordance with EN10025 standards, providing unparalleled strength for heavy-duty applications.
- Reduced Thermal Bridging: Elimination of baseplate and factory-fitted insulation helps minimize thermal bridging, improving energy efficiency and sustainability.
- Optimized Cavity Support: Engineered to fit cavities ranging from 50mm to 65mm, with precise measurements for both the outer and inner leaf, this lintel provides better cavity support.
- Superior Coating: Supergalv coating significantly extends the Birtley HD50 lintel’s lifespan, protecting it comprehensively against the threat of damages related to corrosion.

Excellent service from a great company
Ordered 2T of midnight blue slate chipping (2 pallets of 50 bags each) Very nice product at a great price. Contacted quickly after order to arrange a suitable delivery date. Delivery was as arranged. Customer service is excellent including follow up call to ensure everything went well. All in all I would highly recommend Armstrong Cheshire.
Great Customer Relations
Due to a mistake in communication ( mostly my mistake) the first delivery of bulk aggregate went to an address I used to live at. After asking to have a replacement delivery to the correct address Armstrong Cheshire re-scheduled the delivery within 3 days and with fantastic customer relations. I cannot recommend this company enough.
