During installation and use, the information and regulations in accordance with the DIBt approval Z-14.4.706 must be observed. 4 stainless steel drilling screws with a thread diameter of at least 6 mm and a sealing washer of at least 14 mm are required for fastening in accordance with DIBt approval Z-14.1-4.706 or Z-14.1-537 can be used. Suitable tools with torque control must be used.
The planer, user and/or installer of these parts is responsible for all necessary engineering and design to ensure the Multi-Trapezoidal Bracket MTH has been properly spaced and configured. Responsible for the stability of a building structure is the building owner or the owner of the installation. The installer is responsible not only for the application and the installed system, but also for the roof on which the system is installed. Anyone who installs a system on an existing roof without having checked the stability beforehand violates existing law. If he is not able to assess the load-bearing capacity himself, he must obtain a static calculation from a specialist. On request, we will be happy to send you the specifications for design and dimensioning from the building approval.
Any loads imposed on the fixing products will be transferred to the panels. Panel seams must have sufficient flexural strength to carry these loads. Panels must also be adequately attached to the building structure, and the structure must be sufficient to carry these loads. The makers and RoofTech make no representations with respect to these variables. It is the responsibility of the user to verify this information, or seek assistance from a qualified design or structural professional, if necessary.
PLEASE USE THE PRODUCTS RESPONSIBLY! Panels must be adequately attached to building structure to resist these loads. For critical installations, inquire for specific test data of ultimate tensile load on specific panel materials and seam types. When tabled values are used, screw tensions should be verified and factors of safety should be used as appropriate. The manufacturer and RoofTech expresses no opinions as to the suitability of the products for any specific application or project condition.
The Multi-Trapezoidal Bracket MTH is unsuitable for snow retention and fall protection applications!
The respective installation instructions must always be observed. The user and/or installer bears also the responsibility not only for the professional installation, but also for the roof on which he is mounted. The user and/or installer must always clarify in advance the application possibilities and application of our products in connection with the other used materials and products at the single project.
It must be ensured by the planner and the specialist company responsible for the installation that the planning and installation are carried out strictly in accordance with the national and site-specific building regulations, occupational safety and accident prevention regulations, standards and environmental protection regulations.
The responsibility for the assembly and the applications is in principle not accepted from the producer and RoofTech GmbH. The Installation instructions and and more information to download under “Information” or send us an email for your request.
