Back in 2020 we produced a spreadsheet listing all the sizes of C section that we had available to us as Engineers.  
 
Today we've expanded that list and added a few more manufacturers, including: 
 
Birkbeck Structures,  
Bespoke Structures,  
BHC,  
Caledan,  
Clonoe Custom Sheds,  
DF Sheds,  
Egan Bennet, 
Frameclad,  
Framespace, 
Hamilton Metal Forming,  
Metal Frame Structures,  
Steadman 
 
Update Our Hot State member checks were launched a few weeks ago and have garnered much interest, however one question that keeps being asked is what boards are used and what ratings in terms of time are available so we thought we'd publish an abridged table showing the solutions available. 
 
New Hot State Member capacity tool launched to decrease time and cost for designers and engineers 
 
This week, North Yorkshire, leading structural and civil engineering practice MMCEngineer Ltd launched groundbreaking tool to calculate Hot State Member Capacity and fire ratings. 
 
The new tool which has taken 5 years to develop can calculate Hot State Member Capacities for #LGS as well as offering a fire rating based on board manufacturer test data. 
 
Today, 26th September 2025, our Steve Napper will be presenting to the I Struct E Structures in Fire Forum on "Calculating capacity of Light Gauge Steel under fire load (and why testing is inadequate)" 
Recently we were employed by a client who approached us to design a single storey building for them in light gauge steel. 
 
The client had budgeted £10k for material and £3k to cover our costs with trusses and studs at 400mm c/c for both. We managed to save £5,300 in material costs alone. 
We have continued to develop calculations to allow engineers to calculate load bearing member capacity under fire conditions for light gauge steel members. Now we have added tools to calculate thermal induced bowing based on hot and cold flange temperatures.
