Install S-5! B-Clamps:

The S-5!® B-clamps, made of Brass, are designed for Copper double-folded standing seam paneling. The material properties of the respective metals, the brass B-clamps and the combination with each other must be checked in advance due to possible contact corrosion.

  1. Partially thread the setscrews into the clamp by hand.

 2. Determine how to position the clamp. When attaching to machine-folded seams (regardless of panel profile and geometry), S-5! B-Clamps are designed to engage the seam, as shown in illustration on the top right, with setscrew opposite seam fold.

 3. Tighten the setscrews using a screw gun and the included screw gun bit tip with a tightening force of 15 -17 Nm.
Setscrews should be tensioned and re-tensioned as the seam material compresses, i.e. tighten the first setscrew, then the second; then repeat until each setscrew achieves the recommended torque. The setscrews will dimple the seam material but will not penetrate it. When relying on published load values, setscrew tension should be verified periodically using a calibrated torque wrench as indicated below to ensure the tool is consistently achieving the proper torque range.

4. The B-clamps may hinder the thermally elongation of the profile if, despite the high clamping point of the B-clamps, the foot of a sliding clip extends into the clamping area of the clamp. Than the B-clamps must be placed at a distance of 25 mm from the sliding clips.

5. For critical attachment applications utilizing an M8 or M10 x 16 mm Hex Flange Bolt, tighten the bolt with a tightening force of 18 Nm (160 inch pounds).

Please note for copper applications – also with the S-5! B-Clamps made of brass – in combination with other metals:

Copper is not endangered by other metals due to its position on the positive side of the electrochemical voltage width. Copper can be safely combined with lead and stainless steel. In principle, any combination of copper with lead and stainless steel (material nos. 1.4321, 1.4401, 1.4571) is harmless.
An assembly of copper (also S-5! B-Clamps made of brass) and aluminium is relatively unproblematic if the aluminium has an electrically non-conductive surface due to coating or anodization, so that water containing copper cannot form an electrochemical element with the aluminium. Direct contact between the two metals must be prevented by arranging a joint or an intermediate layer of non-conductive materials (e.g. stainless steel). The copper ions contained in the water cannot then form an electrochemical element with the aluminium.
The arrangement of copper above titanium zinc or galvanized steel should be avoided, as copper ions carried along by draining water can lead to element formation on the titanium zinc or galvanized steel and destroy it. No iron elements should be placed above copper components. In the course of further weathering, these tend to become rusty. Rinse off of this iron oxide can form brown run-off marks on the forming copper protective layer, which are perceived as optical disturbances. However, a danger to the copper material is not to be feared in these cases either.

Please note in general for installations with S-5! Clamps:

  • Please make sure that the load coming into the clamp will be taken by the structure of the roof. Assumption is that the determination has been made that the roof to which the S-5! clamps will be attached is structurally adequate. Any loads imposed on the S-5! clamps 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. In particular, the snow and wind loads, the additional loads from the installations attached to the clamps, as well as the increased loads in the edge and corner areas of the roof construction must be considered.

  • A sufficient number of clamps must be provided. For statically relevant clamps, a distance of at least 500mm from the end of the standing seam profile must be maintained. RoofTech and the makers of the S-5! clamps 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 professional or stress analyst, if necessary.

  •  Responsible for the stability of a building structure is the building owner or the owner or operator. The installer of the system is responsible not only for the system but also for the roof on which the system is installed. Whoever installs a system on an existing roof without having checked the stability beforehand, violates existing law! For critical installations, inquire for specific test data of ultimate tensile load on specific panel materials and seam types. The sufficient holding force of the roofing to the supporting or substructure must always be ensured. The sufficient holding force of the roofing on the supporting or substructure must always be guaranteed. Proof must be provided by the customer or installer. In cases of doubt, a structural engineer must be consulted to determine the loads and its effects.

  • Please note the installation instructions of the respective S-5!® clamps and the other products used! Mounting the S-5!® clamps take care that the set screws and bolts are tightened with the right screw tension as written in each installation instruction (available in all boxes, on the homepage of RoofTech: www.rooftech.de and S-5!: www.s-5.com or please send us an inquiry). When tabled values are used, screw tensions should be verified and factors of safety should be used as appropriate. If you are missing important and necessary information, please request it from us.

  • The thermally induced change in length of the roofing must not be hindered! With some roofs made of profiled sheets (e.g. with round bulb seams, snap folded seams, RibRoof seams, etc.), it must be ensured that the clamps in the sliding area of the sheets are not mounted on or next to the holders of the roofing. In the case of double standing seam roofing, the S-5!® E and B clamps can, under certain circumstances, hinder the thermally induced length change of the sheet if, despite the high clamping point of the S-5!® E and B clamps, the foot of a sliding clip extends into the clamping area of the clamp. In this case, the S-5!® E and B clamps should be placed at a distance of 25 mm from the sliding clips.

  • When installing rigid objects such as rails, pipes, cable ducts, etc. on the clamps, they must be separated at regular intervals (max. 3m in the case of handmade standing seam roofs) in order to limit deformations due to thermally induced length changes (in lengthwise and horizontal direction).

  • In the case of handcrafted metal roofing on wooden formwork, the edge and corner areas should not be covered with PV-modules due to the limited load-bearing capacity of the roofing and the adhesives. In the central area, the skipping of seams is usually not possible. Therefore, we recommend to install clamps on each seam. The installation of PV systems represents a punctual load entry; therefore, we recommend reduced clip distances and screwed clips. The mounting and fastening of the clamp should be carried out between the clips to achieve an optimal load sharing.

  • Please observe the country-specific legal and official regulations for snow retention. Depending on the location of the building, height of the terrain above sea level, roof shape, roof pitch, type of metal roof and the respective holding strength of the S-5! clamps, the suitable snow guard systems must be professionally calculated and designed.

  • The material properties of the respective metals, the combination with each other as well as the installation instructions and regulations of all manufacturers involved (including those of the metal roof) must be observed.

  • The installation of our products should only be carried out by qualified and professional specialists with experience in installing on roofs. The suitability of our sold products for the intended use is checked by the user himself. If technical details are not described separately, this does not release the company carrying out the work from its obligation to check the individual case and clarify the correct technical facts beforehand.

  •  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. Every person who plans and installs with our products is obliged to inform himself independently about all rules and regulations for technically correct planning and installation and to observe them. This also includes obtaining the current status of the necessary rules and regulations.
