The original – the Classic – AlphaJoint.  Well known as the ‘industry standard’ armoured joint, this remains a popular choice for many projects due to its strength and versatility.

AlphaJoint Classic 4010

Benefits

• Heavy duty joint arris protection.
• Shear studs securely anchor the joint into the slab along its length.
• Resistant to twisting caused by the impact of wheeled traffic.
• Efficient load transfer between adjacent concrete slabs with plate dowels.
• Allows controlled horizontal slab movement, preventing random cracking.
• Eliminate vertical movement between slabs during concrete contraction, for a level floor surface.
• Supplied as one unit for easy handling and installation – the two sides are connected with frangible rivets which separate naturally after installation.
• Also available with Permaflex ‘T’ tape system pre-installed as special order – contact our sales team for more information.
