Burning Bar for Steel Cutting and Demolition

Burning bars—also called thermic lances or thermal lances—pack serious cutting power at a scorching 3,600°C. Here's how they work: A steel pipe filled with steel wires ignites using an oxy-acetylene torch, then high-pressure oxygen fuels a powerful exothermic reaction (4Fe + 3O₂ → 2Fe₂O₃ + heat). This creates a continuous burning action that slices through rock, steel, and concrete effortlessly. No electricity needed—just oxygen and fire. A very simple, portable, and incredibly effective tool for tough industrial cutting jobs.

Why It Is Called "Burning Bar"?

Ever wondered why it's called a "burning bar"? The name perfectly captures what it does—it literally burns steel (the combustion process) in a bar-shaped rod. Think of it as an industrial-sized sparkler that melts through anything! You'll also hear it called a thermic lance, thermal lance, or oxygen lance—different names, same incredible tool, same principle. "Thermic" refers to the intense heat generated, while "oxygen lance" highlights the oxygen-fueled reaction. In the field, professionals use these terms interchangeably. Whether you call it a burning bar or thermal lance, you're talking about that powerful 3,600°C cutting beast that transforms oxygen and steel into unstoppable cutting force.
