Architects, Specifiers and Engineers
Collaborative technical support that helps simplify specification, improve buildability and support compliance.
Supporting better specification decisions.
From early design concepts through to construction, we work alongside design teams to help simplify specification, reduce risk and ensure the most appropriate lintel solution is selected for each application.
Our experienced technical team understands the challenges of modern building design, from meeting evolving Building Regulations to achieving higher standards of energy performance and buildability. That’s why every solution is backed by practical advice and proven technical expertise.
We support architects with:
Advice
Early-stage design advice to inform structural and thermal strategies.
Data
Detailed technical data including load capacities, thermal performance and compliance documentation.
Specification
Clear specification wording to reduce ambiguity and ensure intent is delivered on site.
Value engineering support
Value engineering support where cost, performance and practicality need balancing.
Digital specification support
Digital specification support with BIM objects, NBS and CAD integrated into your design workflow.
Engineered for performance and specification
Whether specifying standard steel lintels, thermally efficient Hi-Therm+ lintels, bespoke special lintels or structural steel solutions from our KeyFab division, our products are developed to support the requirements of modern building design.
All products are supported by comprehensive technical data, verified performance information and expert guidance, helping architects and specifiers specify with confidence while meeting regulatory and project requirements.
Architects and specifiers can rely on Keystone Lintels for:
- Structural calculations and technical validation
- Thermal performance data to support SAP and Part L compliance
- Guidance on detailing and junction performance
- Ongoing updates as regulations and standards evolve
"We've been very impressed with Keystone Lintels' products and service. Deliveries were reliable, communication was straightforward, and it's clear why they've built such a strong reputation in the industry."
