Granite Lintels & Structural Stone UK

“Truro Granite Ltd has been supplying granite lintels to builders, architects and heritage contractors across the UK since 2006. With the capability to cut any size, match any finish and deliver anywhere in the country — most lintel suppliers cut to standard sizes. We cut to yours.”

Truro Granite Ltd supplies precision-cut natural granite lintels and structural stone for construction, architectural and heritage projects across the UK. Based in Cornwall and supplying nationwide, we stock and fabricate granite lintels in standard and bespoke sizes — cut to your exact specification and delivered direct to site. Whether you are a builder sourcing lintels for a new build, an architect specifying structural stone for a listed building, or a heritage contractor matching existing stonework on a conservation project, we supply the right granite lintel at the right specification, on programme.

Truro Granite Ltd is one of the UK’s leading granite lintels suppliers — providing natural stone lintels for residential new builds, extensions, renovations and commercial construction projects across England, Wales and Scotland. Our granite lintels are available in standard dimensions for straightforward specification, or cut to bespoke sizes from your drawings for projects requiring non-standard openings. All lintels are cut to precise tolerances, ensuring a clean fit and professional finish on site.

We supply granite lintels to builders, developers, architectural practices and heritage contractors throughout the UK. Our supply chain spans trusted quarries in the UK, Portugal and China — giving us the flexibility to match stone colour, grain and finish to your project requirements. For builders in Cornwall and the South West, we offer the added advantage of local supply from our base in Truro — with shorter lead times and direct access to our team for specification support.

Understanding granite lintel types is essential for correct specification. The most common types supplied by Truro Granite Ltd include: natural cleft lintels — split to a natural face finish for traditional and rural buildings; sawn lintels — precision-cut with clean flat faces for contemporary construction; sawn and fair-picked lintels — sawn faces with a dressed finish for period and heritage applications; and sawn, cleft and punched lintels — combining sawn and hand-dressed finishes for traditional Cornish and South West vernacular buildings.

Each finish type produces a different aesthetic character and is appropriate for different building contexts. Our visual guide shows the full range of available finishes and colours — download it below to help specify the right granite lintel for your project.

Granite lintels are available in a range of standard sizes covering the majority of residential and commercial door and window openings — from 600mm up to 2400mm in length, with depths and widths to suit both structural and decorative applications. For openings outside standard dimensions, we cut lintels to your exact specifications from drawings or site measurements.

All structural granite lintels supplied by Truro Granite Ltd are cut to meet the structural requirements of the opening — with appropriate depth-to-span ratios for safe load-bearing performance. For projects requiring structural calculations or engineer sign-off, we can provide material specifications to support your design team. For guidance on natural stone standards visit the Stone Federation Great Britain and BS EN standards for natural stone.

Granite lintels are one of the most commonly specified natural stone elements in heritage and conservation work — used to repair or replace deteriorating lintels on listed buildings, conservation area properties and period structures where the existing stonework must be matched in colour, finish and character. Truro Granite Ltd has extensive experience supplying granite lintels for heritage projects across the UK — working to conservation-grade specifications and sourcing stone that genuinely matches existing fabric.

For listed building projects, we work closely with heritage contractors and conservation architects to identify the most appropriate stone source and finish — ensuring the new lintels are sympathetic to the existing building and meet the requirements of conservation officers and planning authorities. Our work on ecclesiastical and heritage restoration projects demonstrates our understanding of what conservation-grade stone supply requires. For heritage specification guidance visit Historic England.

Based in Truro, Cornwall, we are the South West’s specialist granite lintel supplier — with deep knowledge of local stone types, finishes and vernacular building traditions. Cornish granite lintels have a distinctive character — a coarser grain, a warmer grey tone and a natural robustness that suits the regional building tradition — and we are experts in matching and supplying Cornish granite for both new build and restoration work across Cornwall and the wider South West.

Beyond Cornwall, we supply granite lintels to construction projects across the UK — from London residential developments to heritage restoration projects in Scotland. Our multi-source supply chain means we can match stone to any regional vernacular or project specification, wherever you are building.

Granite lintels are straightforward to install when correctly specified and handled — but there are important considerations for safe installation on site. Natural granite is significantly heavier than precast concrete or steel lintels — a standard 1200mm granite lintel typically weighs between 40-80kg depending on depth and section. Mechanical handling equipment is recommended for lintels over 600mm in length. Always check weight and structural bearing requirements before ordering.

Truro Granite Ltd can provide material specifications and weight data for any lintel to support your site planning. For HSE guidance on the safe manual handling and mechanical lifting of heavy stone products on construction sites, visit HSE Construction. We are happy to advise on specification, installation considerations and lead times — contact us before ordering if you have questions about a specific opening or project.
