Steel takeoffs in minutes, not hours
Upload your structural drawings. AI detects every steel member. Review, adjust, and export accurate BOMs — with real pricing.
No credit card required. First takeoff included.

Manual takeoffs take hours
Counting every beam, column, and brace by hand across dozens of drawing pages. Time you could spend winning more work.
Errors cost thousands in rework
One missed member or wrong count and your bid is off. You eat the cost or lose the client.
You're quoting too slow to win jobs
By the time you finish a manual takeoff, someone else already submitted. Speed wins in competitive bidding.
How It Works
Three steps from PDF to priced BOM. No training required.
Upload
Drop your PDF structural drawings. Any scale, any complexity.
Detect
AI identifies every steel member automatically — beams, columns, braces, angles, and more.
Export
Review, adjust, and export your BOM with real pricing. Ready to bid.
Already do your own takeoffs?
Skip the AI — plug in your quantities and get instant cost estimates with real market pricing across 550+ AISC shapes.
Everything you need to bid faster
From AI detection to final pricing — one platform, no spreadsheets.
AI Detection Pipeline
Upload a PDF and watch AI find every beam, column, and brace. Each detection shows a confidence score — you review, you approve.
Powered by advanced vision AI that reads real-world structural drawings. Handles text labels, CAD annotations, and hand-drawn markups.

550+ AISC Shape Library
Every W-shape, HSS, angle, channel, and pipe in the AISC database. Real weights, real dimensions.
Instant lookup for any standard steel shape. Weights per linear foot, cross-section properties, and availability — all built in.

Real-Time Pricing Engine
Instant cost estimates based on current market rates. Adjust markup, labor, and material costs to match your shop.
Configure your own rates, overhead percentages, and profit margins. Every estimate reflects your actual cost structure.

Project Dashboard
Track all your estimates, manage clients, and keep your pipeline organized in one place.
Every takeoff, estimate, and client in a single view. Filter by status, search by name, and never lose track of a bid.

Trusted by fabricators
“We used to spend half a day on takeoffs for a mid-size job. Now I upload the PDF, review the detections in 10 minutes, and export a BOM. It cut our estimating time by 80%.”
“The AI catches members I would have missed flipping through 30-page drawing sets. We stopped losing money on underbids because the counts are actually accurate now.”
“I was skeptical about AI for structural steel, but SteelFlo nailed our last three projects. The AISC shape database and real market pricing mean I can turn around proposals same-day.”
You might be wondering...
“Is AI accurate enough for real bids?”
Every member shows a confidence score. You review, you approve, you own it.
“What if my drawings are messy?”
Built for real-world drawings, not perfect CAD files.
“I've already done my takeoff manually”
