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

The S-5!® E-Clamps, made of Aluminium, with an opening slot of 7mm are specially designed and approved for double folded standing seam roof profiles made of aluminium, titanium-zinc, stainless steel or coated galvanized steel and having the appropriate dimensions.

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 without piercing it.

Only use the Original S-5!® E-Clamps:

In contrast to plagiarism and conventional seam clamps, the S-5!® E-Clamps have been tested by independent testing institutes on a large number of double standing seams from various manufacturers.
The S-5!® E-Clamps are also the only seam clamps approved by the building authorities for the Rheinzink double standing seam system. 
DIBt No. Z-14.4-719.

Please note following important information from Rheinzink:

Rheinzink basically only recommends the use of 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results in damage to the roof, then the Rheinzink material guarantee and the Rheinzink system guarantee are of course no longer valid.

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

The E-Clamp with two set-screws (and 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 pieces per box.

The E-Mini (with M8 thread on top and M8 stainless steel bolt) and the E-Mini-FL (with Flange and 18x11mm hole) with one set-screw are utilized in various instances when multiple clamps are required for the attachment of rigid objects to the seams, e.g. rail systems for solar installations, the RoofTech tube snow retentions, signs, walkways, satellite dishes, antennas, lightning protection, cable trays, pipe and cable layingmechanical equipment, etc..
E-Mini: 90 pieces per box, E-Mini-FL: 125 pieces per box.

The following innovations and changes will be made step by step from July 2020. After the current stock of the respective article has been sold off, we will also make the changes.

  • In the future the S-5!® Mini-Clamps will be delivered without M8x16 stainless steel screws. The changeover will take place after the sale of the previous boxes. The M8- screws can then be ordered separately from us, packed with 100 pieces per box.
  • The set screws of the S-5! clamps will be supplied with Torx 30 female thread in the future. A mounting bit (Torx T30) will be supplied in each box as before. The tightening forces remain unchanged.

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-Clamp on double folded seam profile
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:

 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! E-Clamps are designed to engage the seam as shown in illustration on the right.

 3. Tighten the setscrews using a screw gun* and the included screw gun bit tip. 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.

Once installed correctly, these clamps require no maintenance or reinspection for the life of the roof.

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

5. For critical attachment applications utilizing an M8-1.25 X 16 mm Hex Flange Bolt, tighten the included M8 bolt to 160 inch pounds (13 foot pounds).

Please note in general:

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 taken into account. A sufficient number of clamps must be provided. For statically relevant clamps, a distance of at least 500 mm from the end of the standing seam profile must be maintained. RoofTech, the makers and distributor of 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 clamps take care that the set screws and bolts are tightened with the right screw tension as written in each installation instruction (also available under "Information" and on the homepage of S-5!: www.s-5.com). When tabled values are used, screw tensions should be verified and factors of safety should be used as appropriate.

When mounting rigid objects such as rails, pipes, cable trays, etc. on the clamps, these must be separated at regular intervals (max. 3m) in order to limit deformation due to thermal length changes.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 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.

In the case of handcrafted metal roofing on wooden formwork, the edge and corner areas should not be covered with modules due to the limited load-bearing capacity of the roofing and the adhesives. In the central area, the skipping of seams are 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 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 suitability 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.
