W profile machine keel steel roll forming machine

What is a Keel Steel Roll Forming Machine?
At its core, it's a machine that takes a continuous coil of flat steel sheet and progressively bends it through a series of rolls (stations) to create a specific, continuous profile without cutting the metal. The "keel steel" in the name refers to the final product's shape, which resembles a ship's keel—a central, strong backbone.
