JORDAHL® Cast in Anchor Channel Fixings JTA - Cast-in Channel Connection System

The JORDAHL® JTA cast in anchor channel range comprises JTA W hot-rolled, and JTA K cold rolled channel profiles. Both types of anchor channels are used with simple twist-in T-bolts to provide safe and adjustable connections to concrete structures for the resistance of tension and shear loads. With over 100 years of experience the system has proven itself to combine of high reliability with high performance. JORDAHL® JTA cast in anchor channels are evaluated in assessment documents UKTA - 0836-22/6149 and ETA/09-0338.

JTA W hot-rolled anchor channels provide simplicity and reliability of performance for structural connections to concrete that are subject to all load conditions, including oscillating, seismic or dynamic loads.

JTA K cold rolled anchor channels give an efficient method of connecting components to concrete that are subject to predominantly static loads..

Curved anchor channels, anchor channels grouped in pairs and anchor channel corner pieces are available on request.

Load groups:

To provide the widest selection of load performance, a range of 13 cast in channel types are available with standard channel lengths ranging from 150–6000 mm with capacities up to 72 kN design resistance per connection. Standard T-bolt diameters range from M6 to M30.

Features and benefits:

• Efficient and versatile support of high loads.
• Simple connection adjustment to accommodate building tolerances.
• No drilling of concrete or site welding.
• Faster connections with simple hand tools.
• Connections close to concrete edges are possible.
• Easy to replace or re-position connected components.
• Resistant to fatigue, seismic activities, and explosions (hot rolled).
• High tightening torques (hot rolled).
• Approved fire resistance performance.
