DETAN Rod System

Extensive system solutions help to realize complex constructions and interesting designs for internal and external areas.

DETAN tension rods are available in stainless steel (DETAN-E) and steel (DETAN-S).
Numerous product improvements have increased the quality of the DETAN range again, as it fully meets the demands for high quality architectural products.

• DETAN-E in tension rod system stainless steel now with European Technical Approval ETA-11/0311
• an additional type-test report based on the ETA approval and Eurocode 3 allows a straightforward application of allowable loads from audited tables
• permanent quality and production monitoring by supervisory institution
• CE-certification recognized in all European Union countries
• 25% higher load capacity due to the rod's tension capacity 
• tension rods are fully loadable (no reduction factor for single system sizes has to be considered)
• design of allowable loads considering country-specific coefficients M1 and M2 (NAD) with the new DETAN software
• minimum requirements (strength class 235) to building-site connection plates simplify supply
• EU wide standardised design concept
• no requirement for national approvals or certificates
• cross couplers are now available in stainless steel
• cross couplers are a cost effective alternative to anchor discs for cross bracings

• dimensioning of DETAN-E compression rods in stainless steel strength class 235 acc. to General Building Approval Z-30.3-6
• dimensioning of DETAN-E compression rod in stainless steel strength class 235, acc. to Eurocode 3 (EN1993-1-4)

• tension rod system DETAN-S with European Technical Approval ETA-05/0207
• an additional type-test report based on the ETA approval and Eurocode 3 allows a straightforward application of design values from tables
• CE-certification recognized in all European union countries
• tension rods are fully loadable (no reduction factor for single system sizes has to be considered)
• design of allowable loads considering country-specific coefficients M1 and M2 (NAD) with the new DETAN software
• EU wide standardised design concept
• no requirement for national approvals or certificates
• cross couplers are a cost effective alternative to anchor discs for cross bracing

• dimensioning of DETAN-S compression rods in stainless steel strength class 235 acc. to Eurocode 3 (EN1993-1-1)

The DETAN rod systems up to and including 60 mm system diameter are delivered pre-assembled to the customer (from size 76 in individual parts). Large system lengths are separated from the sockets during transit.

• No additional assembly work required on site
• No danger of incorrect assembly through mix-ups
• During the preassembly the rod is set to the maximum adjustment position („om-oj“). The final adjustment to the exact and required system length is done on site by turning the thread
• Free movement of threads ensured

• tension rods are completely hot-dip galvanized after the manufacturing process
• no danger of hydrogen embrittlement
• no flaking zinc
• large spanner notches for reliable rod tightening
• forks and locking nuts are hot-dip galvanized
• internal threads are coated
• threads are optimally protected against humidity and contamination
• standard sealing set for rods with diameters starting from 16 mm

To complement the DETAN Tension Rod system, HALFEN also offers compression rods that fit in perfectly both technically and visually with the system. Compression rods consist of large diameter tubes, which are tapered at the ends so they can be connected to standard DETAN forks.

Exact pre-tensioning is very difficult on system sizes from 30 upwards, this requires special aids such as a hydraulic pretension units. The HALFEN pretension unit for use with DETAN M30 - M60 rods systems provides an effective solution with load transfer using a threaded-flange preventing damages to the rod surface.

• the system is optimised for DETAN Rods
• extra lightweight aluminium design for simple assembly
• targeted hydraulic application for tension up to 425 kN
• no power-source needed
• the high-quality galvanized surface is protected by special load transfer flanges
• simple control of load application with a calibrated manometer
• additional control using optional extensometer, even after load application (if previously gauge marked)
• functional, simple & robust

DETAN Rod Systems offer high quality finishes and seals to protect against corrosion, especially in sensitive areas such as the thread. A further improvement; the spanner notches are milled before the rods are hot-dip galvanized. The forks and locking nuts are coated with a high-quality hot-dip galvanizing for excellent long-term protection against corrosion, as well as good mechanical resistance.
