S-5!^®  B-Clamps for Copper Double Folded Seam

Samples of Applications:

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 B-Clamps made off Brass and the combination with each other metal must be checked in advance due to possible contact corrosion (see also our information below!).

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 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).

• The respective product installation instructions from us and our producer must always be observed (available in all boxes, on our homepage www.rooftech.de or please send us an inquiry). During the entire installation period, it must be ensured that at least one copy of the relevant installation instructions is available on the construction site to all those involved in the installation and that it is strictly observed during installation.

• Installation with our products should only be carried out by specialists and specialist companies with qualifications for the respective installation and with experience in working on roofs. During installation, the warranties of all trades involved and of the roof as well as the respective regulations for work on roofs must be observed (e.g. the use of fall protection, scaffolding with safety gear from an eaves height of 3 m, accident prevention, insurance, etc.). The presence of two persons is mandatory for the entire assembly process in order to be able to guarantee rapid assistance in the event of an accident.

• The respective installation instructions do not release the contractor from the obligation to clarify the possible uses and application of our products, also in combination with the other materials and products used, on the individual property in advance. The user and/or installer also bears the responsibility not only for the professional installation, but also for the roof on which he is mounted. If you are missing important and necessary information, please request it from us.

• In the case of non-observance of our installation instructions, or assembly of our products with components of competitor and in the event of the use and combination offurther components which were not purchased from us, we shall not accept any liability for any resulting defects and damage. The warranty is excluded in this respect.

• The individual types of the S-5! clamps are designed as described for the respective seam and profile types. However, new variants of standing seams and profiles come onto the market regularly. To avoid possible damage, it is important to check the suitability of the clamps for the intended metal roof before installation.

• 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 orsubstructure 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 thecustomer or installer. In cases of doubt, a structural engineer must be consulted to determine the loads and its effects.

• The maximum static loads for the individual products and the roof must always be observed. With very few exceptions, the load-bearing capacity of each individual S-5!® clamp is stronger than the load-bearing capacity of the roof panels or the profiled sheets and their attachment to the supporting structure. This applies not only to thenormal clamps but also to the S-5!® Mini clamps. Therefore, the weak points are usually not the clamps, but the roofing and its fastening.

• Fastening a system increases the roof’s inherent load. The forces from the permanent loads increase and the load-bearing capacity of the roof must be ensured. Please make sure that the loads 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 structural engineer, if necessary.

• 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 capacityof 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.

• 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.

• Through a mounting system, its fastening, any existing intermediate construction and when mounting rigid objects on the clamps, such as rails, pipes, cable ducts, walkways, etc., these must be separated at regular intervals (after a maximum of 3 meters in the case of standing seam roofs) in order to limit deformations due to thermally induced elongation of the materials (in the longitudinal and transverse direction). When installing modules with the S-5! PV-Kit 2.0 in a row from the eaves to theridge, a separation is necessary after a maximum of 10 modules to limit deformations due to thermally induced changes in length of the installed materials.

• 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, roofshape, 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. 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.
