• Structural Load Capacity: Depending on purlin spacing and panel thickness, the systems are designed with sufficient load-bearing capacity to withstand snow, wind, and maintenance loads.

How Are Steel Construction Roof Panel Systems Installed?

Proper installation of steel construction roof panel systems is essential for the durability, safety, and long-term performance of the structure. The installation process is planned according to engineering calculations and follows specific stages, from assembling the structural system to installing the roof panels. Throughout the application, compliance with structural calculations, installation details, and waterproofing solutions plays a critical role in ensuring that the system delivers its designed performance and provides reliable service for many years.

Project Design and Structural Calculations

Engineering calculations and application projects for the steel structural system and the roof panels are prepared by considering the wind, snow, and seismic loads of the region where the building is located.

Installation of the Secondary Structural Framework (Steel Construction)

Columns, steel trusses, and purlins are assembled using bolted or welded connection methods to create the main load-bearing framework of the roof.

Alignment and Surface Preparation

The elevation, axis, and level of the purlins are checked. Necessary sealing tapes and insulation strips are installed on the surfaces where the panels will be applied, preparing them for installation.

Placement and Fixing of Roof Panels

The panels are placed on the purlins starting from the side opposite the prevailing wind direction. They are fixed to the structural profiles using sealed stainless-steel panel screws, commonly referred to as self-drilling or smart screws, at appropriate connection intervals.

Installation of Ridge, Gutter, and Accessory Details

Ridge connections, gutter details, eaves coverings, corner elements, and rainwater gutters are installed. In the final stage, sealing applications at the connection points are completed, and the roof system is made ready for use.

Where Are Steel Construction Roof Panel Systems Used?

Steel construction roof panel systems are preferred in a wide range of structures that require large spans to be covered safely and economically, thanks to their lightweight construction, high strength, and modular design.
