Steel Control

Steel control joint is a great way to ensure that concrete cracks where you want it to. Made from galvanized steel, this product creates a controlled point of weakness for concrete slabs. It creates a clean, straight joint while saving time and expense of having to return to saw cut joints. Steel control joint comes in 10′ lengths and is easily cut with snips to the desired length, depths available are      1½”, 2″, 3″, 4″.

The original ZipStrip control joint is a rigid polystyrene extrusion that creates a straight line, controlled crack on the surface of all on grade slabs. ZipStrip eliminates random cracking in all variations and thicknesses of slabs where a control joint is required. ZipStrip is the economic alternative to saw cutting to create similar straight line surface joints.
