At J Johnstone Engineering, we recently fabricated and installed a triple structural steel A-frame truss for a residential project in Cumwhitton, Cumbria. Working alongside a prestigious award-winning building firm, we led the project from fabrication through to expert installation, delivering EN1090 Class 2 certified steelwork tailored for home extensions, self-builds, and refurbishment projects.
Project Overview
- Location: Cumwhitton, Cumbria
- Client: Prestigious award-winning building firm
- Scope: Fabrication and installation of triple A-frame steel truss
- Steel Type: S355 structural steel beams
- Finish: Red oxide primer coated with bitumastic paint for corrosion protection
- Compliance: Fully compliant with EN1090 Class 2 standards
This triple A-frame truss offers excellent structural support for pitched roofs and heavy load-bearing applications.
Bespoke Steel Fabrication Process
Our in-house team fabricated the entire triple A-frame truss using premium structural steel beams. The process involved precise cutting, welding, drilling, and thorough quality checks to meet EN1090 Class 2 execution standards. The steel was finished with a red oxide primer and bitumastic paint for long-lasting corrosion protection suitable for the project’s environment.
Expert Installation
We managed the installation process on site, coordinating logistics and ensuring precise fitting. While we partnered with Lawson Cranes to safely lift and position the steel components, all installation work, securing, and final checks were expertly handled by our skilled team.
