Load-bearing sheet T45-30L-905

Optimal geometry of the T45 enables cost efficient roof structures for reasonable spans.

For the optimal structural dimensioning, use Ruukki’s roof dimensionin software, Poimu.

T45 is targeted for roof structures with spans less than 3.5m.

All of Ruukki’s load-bearing sheets can be equipped with smart technology. The new Ruukki® Roof Sensor system tracks snow loads on roofs in real time, prevents dangerous situations and saves costs by making snow removal smarter. Read more about the benefits of smart roofs here.

    Roof Sensor

    Introduction to Ruukki Roof Sensor system

    The purpose and aim of the Ruukki® Roof Sensor System is to measure and visualize the snow load on roofs constructed with Ruukki load bearing sheets. The system provides valuable information for safety and management decisions concerning the building. It’s accessory for all Ruukki load bearing sheets and is available for new and old roofs that have access to the lower surface of the sheeting. The system is easy to install and use and there is no need for further monthly service fees. 

    Following corner stones are needed in the system 
    1. In structural design, Ruukki’s POIMU roof dimensioning program must be used
    2. Ruukki Roof Sensors location must be defined by the structural designer and sensors appropriately fitted by the installer
    3. The parameters needed in system configuration are defined in POIMU program
    After the sensors installation and system configuration, the system gives warnings when designers defined characteristic snow load level have been reached. Further warnings will be given well before load bearing sheeting is approaching its ultimate capacity. Warnings are given by visual light on the roof level and through user interface in web pages in a local network.
