Light Steel Frame Trusses as the Future of Roofing in Rwanda: A Technical Breakdown

At Mr Roof, we’re revolutionizing the construction industry in Rwanda with cutting-edge solutions that outperform traditional methods. One standout innovation is our use of light steel frame trusses, which bring unmatched benefits over old-school wooden trusses and bulky steel hollow sections. Discover how these modern marvels can elevate your next building project with superior strength, precision, and efficiency. Say goodbye to outdated materials and hello to the future of roofing!


1. Strength and Durability


Light Steel Frame Trusses:

- High Strength-to-Weight Ratio: Light steel frame trusses boast an exceptional strength-to-weight ratio, making them incredibly robust without adding excessive weight to the structure. This results in a more stable and resilient building framework.

- Longevity: Unlike wood, steel does not warp, crack, or rot over time. Light steel trusses are also resistant to pests such as termites, ensuring a longer lifespan and less maintenance.


Wooden Trusses:

- Susceptibility to Environmental Factors: Wooden trusses can degrade over time due to moisture, pests, and temperature changes. They are prone to warping, cracking, and rotting, which can compromise the structural integrity.

- Maintenance: Wooden trusses require regular maintenance and treatment to prevent decay and pest infestation.


Steel Hollow Sections:

- Weight: While strong, steel hollow sections can be significantly heavier than light steel frame trusses, adding unnecessary weight to the structure and complicating the installation process.

- Corrosion: Steel hollow sections are susceptible to corrosion if not properly treated and maintained, especially in humid environments.


2. Precision and Flexibility in Design


Light Steel Frame Trusses:

- Precision Engineering: Manufactured with precise specifications, light steel frame trusses ensure consistent quality and fit. This precision reduces on-site adjustments and errors during installation.

- Design Flexibility: Light steel can be easily shaped into various forms, allowing for innovative architectural designs and complex roof structures without compromising strength.


Wooden Trusses:

- Variability: Natural variations in wood can lead to inconsistencies in truss performance. Additionally, complex designs can be challenging to achieve with wood due to its inherent limitations.

- Customisation Limits: Wooden trusses are less flexible in accommodating intricate design requirements compared to steel.


Steel Hollow Sections:

- Limited Flexibility: While strong, steel hollow sections are less adaptable to unique or complex designs due to their rigidity and weight.

- Fabrication Requirements: Custom shapes and designs often require additional fabrication, increasing time and costs.


3. Efficiency in Installation


Light Steel Frame Trusses:

- Ease of Handling: Due to their lightweight nature, light steel trusses are easier to handle and transport, simplifying the installation process and reducing labour costs.

- Faster Installation: The precision manufacturing of light steel trusses allows for quicker assembly on-site, speeding up the overall construction timeline.


Wooden Trusses:

- Heavier and Bulkier: Wooden trusses can be cumbersome to handle and require more labor for installation. The variability in wood quality can also slow down the construction process.

- Manual Adjustments: On-site adjustments are often needed, which can delay installation.


Steel Hollow Sections:

- Complex Installation: The heavier weight and bulkier nature of steel hollow sections make them more challenging to install. Additional equipment and labor are often required, increasing costs and installation time.

- Connection Challenges: Joining steel hollow sections can be more complex and time-consuming, often requiring welding and additional hardware.


4. Environmental Impact


Light Steel Frame Trusses:

- Recyclability: Steel is 100% recyclable, making light steel frame trusses an environmentally friendly option. They can be repurposed or recycled at the end of their lifecycle, reducing waste.

- Sustainability: The production process of light steel is highly efficient and produces less waste compared to traditional building materials.


Wooden Trusses:

- Deforestation: The use of wooden trusses contributes to deforestation and the depletion of natural resources. Sustainable forestry practices can mitigate this, but wood remains a less sustainable option overall.

- Waste: Wood waste from construction can be significant and is often not recyclable.


Steel Hollow Sections:

- Recyclability: Like light steel frame trusses, steel hollow sections are also recyclable. However, their higher weight can lead to increased environmental impact during transportation and installation.

- Resource-Intensive Production: The production of steel hollow sections is resource-intensive, leading to a larger carbon footprint compared to light steel frames.


Light steel frame trusses offer clear technical advantages over wooden trusses and steel hollow sections. They combine strength, durability, design flexibility, and ease of installation with a lower environmental impact. At Mr Roof, we believe in harnessing these benefits to provide superior roofing and structural solutions for our clients in Rwanda. 

By choosing light steel frame trusses, you are investing in a modern, efficient, and sustainable construction method that stands the test of time.
