Structural Steel A-Frame Truss Installed for Roof and Window Support in [Location]

🏭 Project Overview

J Johnstone Engineering recently completed the design, fabrication, and installation of a double steel A-frame truss system. The structure was engineered to support both roofing and large window units, requiring precise fabrication to meet CE standards and seamless on-site assembly.

This project was a perfect example of our workshop-to-site service, demonstrating the strength and reliability of our in-house fabrication and experienced site team.

🔧 Project Details

  • Structure: Double A-frame steel truss with supporting legs
  • Purpose: Load-bearing support for roof and window installation
  • Standards: Fabricated in-house to meet full CE marking requirements
  • Assembly: Trusses were mechanically fastened on-site
  • Installation Method: Hoisted into place using a site crane
  • Team: Installed by our experienced engineering team without issue

The job involved careful coordination between workshop and site teams to ensure the steel sections aligned perfectly. Once transported to site, the trusses were bolted together and lifted into position safely and efficiently.


🏁 The Result

The completed structure fit precisely into place, allowing follow-on trades to proceed with glazing and roofing without delay. The client was visibly relieved to see the frame installed smoothly and praised the professionalism of the entire process.

“A job well done – from planning to crane lift, the whole process was seamless. We’re over the moon with the result.” – Satisfied Client
