Roof Truss Construction in Light Gauge Steel Structures

Roof Truss Construction in Light Gauge Steel Structures: In today’s construction industry, light steel structures are becoming increasingly popular. This construction system offers many advantages, such as fast installation time, durability, and long lifespan. One of the most critical components of light steel structures is the roofing system. The roof serves as the building’s protective shield, safeguarding the interior from external elements. In this blog post, we will explore the roofing techniques used in light steel structures and the benefits they provide.

Roof Truss Construction in Light Gauge Steel Structures: Layers for High Insulation and Durability

What is a Light Steel Structure?

Light steel structures, also known as LGS (Light Gauge Steel) systems, are made by combining thin, galvanized steel profiles. This system combines the durability of steel profiles with the advantages of a lightweight structure. Thanks to its resilience, fast assembly, and high insulation performance, it is widely used in residential, office, and commercial building projects, especially in earthquake-prone areas.

Layered Roofing in Light Steel Structures: A Solution for Insulation and Durability

In light steel structures, the roofing system has a multi-layered design, with each layer serving a different function. This layered system maximizes the thermal, acoustic, and water insulation of the interior while enhancing the roof’s durability. Here are the standard layers used in a light steel roof:

Steel Frame (Primary Support)
The steel frame forms the primary skeleton of the roof, providing a strong and durable foundation for the structure. This lightweight steel frame reduces the overall weight of the roof structure while offering robust support. It helps ensure the roof remains stable for years and provides resistance to natural disasters.
11mm OSB Board
The 11mm-thick OSB board placed on the steel frame adds rigidity to the roof. The OSB board creates a structural bond between the layers, enhancing the roof’s durability. It also provides a smooth surface for the placement of additional insulation layers.
5cm, 120 kg/m³ Density Rock Wool
Placed on the OSB board, the 5cm thick and 120 kg/m³ density rock wool provides thermal and acoustic insulation. Rock wool improves the building’s energy efficiency by offering high insulation and prevents external sounds from entering the interior. This layer maintains interior comfort in both hot and cold weather conditions.
15mm OSB Board (Second Layer)
The second layer of 15mm OSB board placed on the rock wool protects the insulation layer and further increases the roof’s rigidity. This layer supports the water insulation membrane and maintains the roof’s structural integrity.
Waterproof Membrane
The waterproof membrane applied on top of the OSB layers protects the roof against water. This layer prevents rain, snow, and moisture from penetrating the roof, protecting the structure. Waterproofing significantly enhances the durability and longevity of the roof, especially in rainy regions.
5×10 Double-Sided Batten Frame
A 5×10 cm double-sided batten frame is added to create an air gap that helps in ventilation and prevents moisture buildup under the roofing material. This frame also provides additional support for the tile covering and enhances the durability of the overall roofing structure.
Concrete Tile Covering
The concrete tiles on the top layer of the roof provide an aesthetic appearance while ensuring high resistance to external weather conditions. Concrete tile covering protects all layers of the light steel structure, maintaining the structural integrity of the building and ensuring waterproofing.

Advantages of Light Steel Roofing Systems

This layered system offers several benefits for light steel roofing:

High Insulation Capacity: It enhances thermal and acoustic insulation, ensuring interior comfort. With excellent insulation, it improves energy efficiency and reduces heating and cooling costs.
Water Resistance: The waterproof membrane and concrete tile covering make the roof impermeable to water, protecting it from rain and moisture.
Durability and Lightweight: The steel frame is strong yet lightweight, making light steel roofs particularly safe in regions prone to earthquakes.
Easy and Fast Installation: The installation process of light steel structures is considerably faster than traditional construction methods. This system, formed by assembling pre-prepared components, saves time.

Why Choose Light Steel Roofing Systems?

Roof Truss Construction: Light steel roofing systems are an ideal solution for projects that prioritize durability and insulation performance. They are especially preferred in environmentally friendly structures, energy-efficient buildings, and projects that emphasize sustainability. Due to their long lifespan, light steel roofs reduce investment costs and require minimal maintenance. Additionally, they offer an aesthetic appearance, complementing modern architectural designs.

The multi-layered structure used in the roofing systems of light steel structures maximizes the durability, energy efficiency, and comfort of buildings. With the robustness of the steel frame, the durability of OSB boards, the high insulation capacity of rock wool, the ventilation provided by the double-sided batten frame, and the aesthetic appeal of concrete tiles, light steel roofs are emerging as a leading technology in the construction industry. As the demand for energy efficiency and climate adaptation grows, light steel roofing systems stand out as both a comfortable and environmentally friendly solution.
