The new and improved generation of roof hooks for the Eco and Rapid 2+ series generates significant savings in installation time and costs: The roof hooks are welded in one piece and come in 6 or 8 mm bar thickness. They are made of the high-strength steel grade S700MC in accordance with EN 10149-2: 2013-12 and have already been granted European Technical Approval (ETA). Their strength, which has been significantly increased compared to the predecessors, meets the requirements for mechanical strength, stability, structural integrity and durability stipulated in EU Regulation 305/2011.
PV systems on tiled roofs with wooden substructures can thus be installed with fewer fixing points per kilowatt of output. This not only saves material costs but also installation time. A new zinc flake coating makes the roof hook particularly corrosion-resistant.
In addition, the Schletter Group has further optimized its product portfolio in order to simplify warehousing and logistics for its wholesale partners. This was driven by a consistent further development of the modular system. Above all, this means that applications which used to require special products that had to be stocked by the resellers in small quantities can now be installed with large-volume standard stock items that are used in specific combinations. “The customer is thus able to order at a much lower price, as it’s easier to get special price quantities,” explains Manuel Schwarzmaier, Head of Roof Projects.
One example is the “Alu Tile” roof hook with a replacement metal roof tile. In the future, Schletter will offer a universal fastener, which can be freely combined with any metal roof tile according to the “one fits all” principle. In the past, these products had only been only available as pre-assembled sets.
And the Schletter Group has also added similar modular solutions for corrugated and trapezoidal sheet metal roofs to its product range. These are ready-made hanger bolt sets, which, in combination with various mounting plates and adapters, cover all common roof shapes. The trapezoidal sheet system “Single Fix” has been optimized according to the same principle: Customers will now be able to order and stock larger quantities of the universal trapezoidal sheet metal holder and then combine it with application-specific rails and screws.
Furthermore, Schletter managed to reduce the need for custom-made products: In future, the Fix T and Fix E trapezoidal sheet metal fasteners will no longer be manufactured specifically for each project, but will be provided by Schletter in all common sizes as catalogue products.
