    Should fire-protection brackets and apparatus panels be laser-cut or waterjet-cut?

    Laser is faster and cleaner on mild steel and stainless under about 1 inch — bracket plates, escutcheons, fire-truck body panels. Waterjet wins above that thickness and on anything heat-sensitive: thick aluminum, titanium, gasket material, layered composites. Waterjet leaves no heat-affected zone, so on a part that will later be welded into a fire-rated assembly you avoid pre-existing microcracks at the cut edge.
