The Halfen System

A Worldwide Reputation for Excellence

HALFEN-DEHA. WORLDWIDE LEADER IN CURTAIN WALL CONNECTIONS

In 1929 HALFEN started to produce adjustable connection sys-tems in Germany which soon became known as “Halfen chan-nels“. Now used worldwide, the amount of Halfen channels in-stalled in the past 10 years alone would almost span the globe. The product allows adjustable connections to precast concrete as well as for concrete poured at the constructions site. Halfen channels are ideal, for framing applications, and for facade fi -xing solutions. A highly competent Research and Development team makes sure, that HALFEN-DEHA maintains its reputation as technology leader by offering the most innovative and the user-friendly fi xing and anchoring systems.

FASTENER INFORMATION

Welding is slow, is a fi re risk, and needs to be closely checked for quality.

Weld and paint splatter can cause expensive damage to the facade.

Welded connections require painting to give minimal corrosion protection. Welding requires diffi cult repositioning of heavy equipment and a costly energy supply.

18

CURTAIN WALL FIXING WITHOUT HALFEN CHANNELS: THE DISADVANTAGES

WELDING

• Risk of sparks starting fi res and damaging glass & aluminium facade = high risk & high cost.

• Quality welding diffi cult to achieve and check on site = high risk.

• Welding needs a lot of time and should be tested to verify quality = slow installation & high risk.

• Painting required after welding to provide any corrosion protection = poor corrosion protection, more time, another operation to check, dripping paint damages facade and creates health hazard.

• Heavy electrical equipment, trailing wires, and electricity = safety hazards.

• Welds must be broken and re-welded if adjustment needed after initial installation = slow installation.

• Embedded plates are designed per project and need testing to verify performance.

Cast-In Channels Welding Plates The only tool required.
