S-5!®  E-Clamps for double folded seams

The S-5!® E-Clamps with an opening slot of 7mm are specially designed and approved for double folded standing seam roof profiles. 
The E-Clamps, made of Aluminium, are suitable for all roofing materials except copper.

The special features of the S-5! E-Clamps are the exact fit on the seam and the high pressure point of set screw which will compress the metal at the seam without piercing it.

Only use the Original S-5!® E-Clamps:

In contrast to plagiarism and conventional seam clamps, all three S-5!® E-clamps have been tested on a variety of double standing seams and materials from various manufacturers by independent testing institutes and are also approved by the building authorities for the Rheinzink double standing seam system: DIBt-Zulassungs-Nr.: Z-14.4-719.

Please note following information from Rheinzink:

Rheinzink basically recommends to use only the original S-5!® E-Clamps, as only these have the official approval in connection with their roofs and thus offer the only possibility that a structural engineer can provide a static proof for the entire system. When using other clamps, the static values that are deposited in the approval for the S-5! clamps, are missing.

Should craftsmen or planners nevertheless work with other, not approved clamps and this results in damage to the roof, then the Rheinzink material guarantee and the Rheinzink system guarantee are of course no longer valid.

There are 3 options of S-5!® E-Clamps:

Mounting on double folded seam
E-Clamp
E-Mini
E-Mini-FL

The E-Clamp with two set-screws, two M8 threads on top and one M8 stainless steel bolt, is used for heavy demands e.g. fall protection systems, in the S-5! ColorGard® snow retention and other heavy-duty applications.
E-Clamp is packed with 60 pcs. per box.

The E-Mini with one set-screw and M8 thread on top and the E-Mini-FL with one set-screw and Flange with hole (18x11mm) are utilized in various instances when multiple clamps are required for the attachment of rigid objects to the seams, e.g. S-5-PVKIT® 2.0, rail systems, the RoofTech tube snow retentions, signs, walkways, satellite dishes, antennas, lightning protection, cable trays, pipe and cable layingmechanical equipment, etc..
The E-Mini-FL is mostly used in the solar sector for rail systems with screw channel at the bottom.

E-Mini is packed with 90 pcs. per box.
E-Mini-FL is packed with 125 pcs. per box.

Stainless steel screws M8x16 (A2, DIN 6921), hexagon with flange and locking serration, can be ordered separately. 
PU: 100 pieces per box.

Examples of Applications:

ColorGard snow retention with E-Clamps
PV-mounting and snow retention with E-Mini
 Rails mounted on E-Mini-FL on a double-folded seam roof

S-5! E-Mini on a Aluminium double folded seam
S-5! E-Mini-FL under Rail with a underside screw channel.

Install S-5!® E-Clamps:

  • Partially thread the setscrews into the clamp by hand. Determine how to position the clamp. When attaching to machine-folded seams (regardless of panel profile and geometry), S-5!® E-clamps are designed to engage the seam as shown in illustration on the right, with the “Nose” under the seam.
  • If the foot of a sliding clip extends into the clamping area of the clamp, the thermal elongation of the seam can be hindered. The clamps must then be placed at a distance of approx. 25 mm from the sliding clip.
  • The set screws are fitted with the S-5!® mounting bit with a tightening force of 15 -17 Nm. For galvanized steel with a thickness of more than 0.7 mm, tighten with 18 – 20 Nm.
  • Tighten the set screws on the E-Clamps and tighten both again.
  • Many screw-drivers do not always offer a constant tightening force. The tightening force must therefore be checked with a calibrated torque wrench and the set screws tightened if necessary.
  • If the a M8x16 stainless steel screw is used for mounting the further application, it must be tightened with a torque of 18 Nm.

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.
