Steel Selector is the ultimate digital handbook for structural engineers, steel detailers, fabricators, and architects. Designed for speed and accuracy, it replaces cumbersome charts with a clean, modern interface that lets you find the exact properties you need in seconds.

VISUAL & INTUITIVE Unlike basic spreadsheet apps, Steel Selector features Dynamic Diagrams. Every shape is rendered with a crystal-clear, high-contrast graphic that updates instantly as you make selections. Dimension lines clearly indicate exactly where measurements like Depth (d), Flange Width (b f ​ ), and k det ​ apply, eliminating guesswork.

SMART SELECTION Finding the right beam is faster than ever. Our Smart Picker system filters data intelligently: simply select your nominal Depth or Size, and the app instantly updates the available Weights or Thicknesses. No more scrolling through lists of hundreds of irrelevant sizes.
