About ColdMatrix

ColdMatrix Tools was built by a working prefab and cold-storage contractor with hands-on field experience — not a software company guessing at formulas from a textbook.

Every calculator on this site is built around real fabrication practice: standard panel thicknesses, real-world density figures, and the kind of sizing questions contractors and fabricators actually ask on-site every day.

Our goal is simple: give contractors, fabricators, and buyers fast, practical sizing references — free to use, with no signup required.
