Iron-Clad™ Joint Assembly
Product Description

Armored Joints for Spall-Free New Construction Joints

Iron-Clad™ Joint Assemblies are armored joints engineered to eliminate spalling in floors with small, hard-wheeled lift truck traffic. These armored joints are ideal for controlled environments where limited thermal expansion and contraction are expected. Iron-Clad™ joint assemblies protect slab edges and ensure adjacent surfaces remain in the same plane with repetitive loading when used with traditional plate dowels. High-tolerance steel bars have square edges for exact and simple concrete finishing. The Iron-Clad™ joint is assembled with nylon nuts that yield with normal concrete shrinkage to reduce joint cracking. And, the built-in joint-fil bar supports joint filler and allows wheels to transition smoothly across the joint. Iron-CladTM joints assemblies for consistent and simple installation:

  • Arrives on site fully assembled
  • Installation is quick using traditional timber forms with plate dowels
  • Smooth, square edges provide a flat finishing surface
  • Built in joint-fil bar supports the semi-rigid joint filler
  • Newly designed mounting brackets allow for simple installation and form stripping
