Brontes — Structural Steel ERP

Structural Steel · Run Like a Shop, Not a Spreadsheet

From bid to bolt-up, one system for the whole fabrication shop.

Brontes replaces the spreadsheets, disconnected PDFs, and phone calls to the shop floor with one connected system — sales pipeline, estimating, project management, production control, purchasing, and inventory, built specifically for structural steel fabricators.

Most fabrication shops run their business across five tools that don't talk to each other — a CRM (or an inbox) for sales, a spreadsheet for estimating, another spreadsheet for the cut list, a shared drive for drawings, and a whiteboard for the shop floor. Brontes is built to be the one system that actually reflects how a job moves through a real shop: from a bid, to an estimate, to a project, to a material and production plan, to a shipped and erected piece — the same path your steel actually travels.
