Updated Racking to SCI P437
Posted on 8th November 2024 at 11:17
As specialists in software development for the light gauge steel (LGS) sector, we are committed to providing innovative solutions for engineers, estimators, and manufacturers worldwide.
Our latest software update integrates the comprehensive design guidance outlined in SCI P437. This update necessitates an increase in the number of braced bays required for optimal racking performance, which is crucial for maintaining structural integrity and ensuring safety under load conditions. While this may seem like a significant adjustment, users can still design within the framework of ED002 principles, ensuring compatibility with existing methodologies.
The update not only adheres to the latest industry standards but also enhances performance through improved sway control and structural resilience. As a result, engineers and developers can achieve more efficient designs while conforming to SCI guidelines. This is particularly beneficial for those utilizing Tedds and Trimble, as our software allows for seamless integration and maximisation of these tools for better design outcomes.
By embracing the latest improvements in racking performance and adhering to SCI P437, our users can confidently design structures that meet the evolving demands of the construction industry. The increased requirement for more bays ensures enhanced stability, allowing for dynamic load support and better long-term reliability.
At Modern Engineered Software Solutions Ltd., we pride ourselves on delivering cutting-edge software tailored to the needs of the LGS market. Trust us to enhance your design capabilities and elevate your engineering projects with our advanced racking solutions.

Summary of designs in image below.
It can be seen that while there is consistency across the versions / methodologies of the old ED002 method of limiting bracing forces to 4.5kN for a bay 600mm wide and 2.45m high across both standards, the new method as proposed in P437 consistently doubles the numbers of braced bays required at ground floor level for both standards.
The calculations are based on the dimensions and loads used in the worked example of P437 for consistency and may not be appropriate for all projects or typical. It is noted by the author that the gauge of stud used has a large affect on the force the bay can carry, and thus the number of bays required. The calculations are all based on 1.6mm gauge.
