SteelFlo vs Ferra (Bidferra): Honest Comparison
Updated October 2026. Ferra's 1.5 release (September 22, 2026) opened self-serve signup and added connection detection, so parts of our July version were out of date. This page now reflects what Ferra publishes today.
Short answer: SteelFlo and Ferra overlap more than they did in July. Both now let you sign up and try the tool without a sales call, and both detect connections. SteelFlo is a self-serve AI takeoff tool — upload a PDF, review every detected member on the drawing, export a priced BOM — with coverage across six steel standards, a broad member scope (plates, angles, channels, HSS, cold-formed), and published pricing (3 free takeoffs, then plans from $399/mo). Ferra positions itself as bid intelligence for North American structural steel fabricators: takeoff plus go/no-go bid guidance, revision control, a 3D model, and Tekla PowerFab and IFC export. The differences that remain are standards coverage, published pricing, and member breadth on our side, and bid intelligence, revision comparison, 3D, and PowerFab export on theirs.
Both companies are young and moving fast, so treat this as a snapshot as of October 2026. Where Ferra's public information is thin, we say so rather than guess.
What is Ferra (Bidferra) and who is it for?
Ferra (bidferra.com) is an AI-powered estimating platform aimed at structural steel fabricators, with an emphasis on the bidding process as a whole rather than just quantity extraction. Its public modules are Bid Intelligence (go/no-go guidance), Steel Takeoff, Revision Control, and a 3D Model. Release 1.5 added connection detection by physical type (shear tab, moment, gusset) with bulk editing, column properties read from schedules (size, splices, base plates), joist and brace detection, and a rebuilt 3D viewer. Exports include Tekla PowerFab, IFC, CSV, and PDF.
The company reportedly raised roughly $3.3M around the turn of 2025-26, lists offices in Wilmington, DE and Toronto, and names large shops such as Banker Steel, Gridiron Steel, and Holley Steel as customers. It presented at NASCC 2026. That puts real engineering resources and real fabricator feedback behind the product. It is one of several new entrants we tracked in our roundup of new AI steel takeoff tools in 2026 — the category has gotten crowded, and that's mostly good news for fabricators.
Ferra's go-to-market has changed. As of 1.5 you can start for free without booking a demo, and a demo is still offered if you want one. The free-tier limits aren't published, and there is no public price list (its pricing page doesn't exist as of this writing). Its customer list and feature set point at mid-size and larger fabricators bidding steady commercial work in North America.
If that's you, Ferra is worth trying. If you work outside North American standards, or you want to see a price before you sign up, keep reading.
What does SteelFlo do that Ferra doesn't?
Three things stand out: standards coverage, member breadth, and published pricing. Connection detection and self-serve trials used to be on this list; Ferra now offers both, so they aren't differentiators anymore.
| Capability | SteelFlo | Ferra |
|---|---|---|
| AISC (US) sections | Yes | Yes |
| BS/IS (UK, India) | Yes | Not published |
| EN (Europe) | Yes | Not published |
| AS/NZS (Australia, NZ) | Yes | Not published |
| GB (China) | Yes | Not published |
| CFS/SSMA (cold-formed) | Yes | Not published |
| Section database | 4,700+ sections across 6 standards | Not published |
| Plates, angles, channels, HSS, cold-formed members | Detected | Beams, columns, joists, braces; misc metals stated as a next priority |
| Connection detection | Yes (bolts, plates, welds, shear tabs, end plates) | Yes (as of 1.5: shear tab, moment, gusset) |
| Self-serve trial | Yes — 3 free takeoffs, no card, no demo | Yes — open signup since 1.5; free-tier limits not published |
| Published pricing | Yes — Free, $99 one-job pass, from $399/mo | No |
| Shape reference pages and calculator | Yes, public | Not published |
Standards. SteelFlo detects the drawing's standard automatically and validates every member against a database of 4,700+ sections spanning AISC, BS/IS, EN, AS/NZS, GB, and cold-formed SSMA. If your work is 100% domestic US wide-flange, this matters less. If you ever see IPE/HEA sections on a European client's drawings, UB/UC on a UK job, or SSMA studs on a light-gauge package, it matters a lot. Ferra's public materials describe a North American structural steel focus; we found no published claims of international standard support.
Member breadth. SteelFlo detects plates, angles, channels, HSS, pipe, and cold-formed members alongside beams and columns. Ferra's 1.5 release covers beams, columns, joists, and braces, and it says misc metals is its next priority. If your packages carry a lot of plates, lintels, or angles, test that on both.
Connections. SteelFlo detects connection details — bolt counts and grades, shear tabs, end plates, weld callouts — and feeds them into the BOM. Ferra 1.5 now classifies connections by physical type (shear tab, moment, gusset) with bulk editing, so this is closer to parity than it was in July. Ferra says it does not do connection design, and neither do we: both are detection and counting. We compared another tool with connection detection in SteelFlo vs SketchDeck LIFT.
Self-serve. Both tools now let you sign up and run your own drawings without a sales call. You can sign up for SteelFlo, upload your own PDF, and see boxed detections in the same sitting. For an estimator deciding whether AI takeoff is real or vaporware, running your own ugly, scanned, half-raster drawing through the tool is the only test that counts, whichever tool you choose.
What does Ferra do that SteelFlo doesn't?
Fair is fair — Ferra has genuine capabilities SteelFlo currently lacks.
| Capability | Ferra | SteelFlo |
|---|---|---|
| Bid tracking / pipeline intelligence | Yes | No — estimates dashboard only |
| Drawing revision comparison | Yes | No — each takeoff is independent |
| 3D visualization / export | Yes | No — 2D PDF review |
| Tekla PowerFab and IFC export | Yes | CSV and built-in pricing engine; no native PowerFab or IFC |
| Named large-shop customers | Banker Steel, Gridiron Steel, Holley Steel | We don't publish a comparable customer list |
| Guided sales onboarding | Yes (demo still offered) | Self-serve (docs + support) |
Bid intelligence. Ferra's framing is that takeoff is one step in a bid, and the platform wraps the whole process: which bids are out, what's pending, how revisions changed the job. SteelFlo tracks estimate outcomes (won/lost) but doesn't attempt full bid-pipeline management. If your shop currently runs bid tracking on a whiteboard and three spreadsheets, that consolidation has value.
Revision diffing. When a GC issues Rev 3 and you need to know what changed from Rev 2, a tool that compares drawing sets and flags deltas saves genuine hours. SteelFlo doesn't do automated revision comparison today — you'd run a fresh takeoff on the new set.
3D. Ferra offers 3D visualization of the structure from the drawings. SteelFlo's review workflow is deliberately 2D: bounding boxes drawn directly on the PDF pages you'll be held to at contract time. Some estimators find 3D genuinely useful for catching scope; others find it a demo feature they never open after week two. Know which one you are.
PowerFab and IFC export. Ferra exports to Tekla PowerFab and IFC as well as CSV and PDF. SteelFlo exports a CSV BOM, a cut list, and a nested order sheet, plus a built-in pricing engine, but has no native PowerFab or IFC export. If your shop runs PowerFab, that integration may matter more than anything else in this post.
How do the pricing models compare?
| SteelFlo | Ferra | |
|---|---|---|
| Trial | 3 free takeoffs, self-serve, no card | Open signup ("Start for free"); limits not published |
| Price | Published: $99 one-job pass, Pro $399/mo, Business $599/mo, Enterprise from $1,499/mo | Not published |
| Pricing basis | Per-takeoff allowance by plan (10, 25, or 60 a month) | Not published |
| Commitment to find out the cost | ~0 minutes | Unknown; no public price page |
SteelFlo publishes its whole price list: 3 free takeoffs, a $99 one-job pass, Pro at $399/month (10 takeoffs), Business at $599/month (25), and Enterprise from $1,499/month (60). Yearly billing is ten months for the price of twelve. You can compute the ROI yourself — if a takeoff that took a day now takes a morning, the math is done by the second job.
Ferra doesn't publish pricing, and we don't know what its free tier includes or what a paid plan costs. We have no verified information about how it quotes, so we won't guess. That's a normal approach for software aimed at larger shops, but go in with your own volume numbers so you can evaluate any quote against a known alternative.
One practical note: unpublished pricing makes year-two renewals harder to benchmark. A flat public price is also a ceiling.
How do accuracy and verification workflows compare?
Every AI takeoff vendor claims high accuracy. The honest version of the claim has two parts: what the AI detects, and what a human verifies.
SteelFlo's published figure is 95-99% accuracy — explicitly framed as AI detection plus human verification, not raw AI output. The workflow enforces it: every detected member gets a bounding box on the drawing, the count is literally the number of boxes, and an estimator confirms or rejects each group before anything exports. High-confidence detections can be bulk-accepted; flagged ones get eyes. Nothing reaches the BOM without the review step. We've written before about why the verification step is where accuracy actually comes from — the same logic applies here.
Ferra also puts a human review step in its workflow, per its public materials, and says it does not sell finished takeoffs with no review. We haven't seen a published accuracy methodology from Ferra, so we won't invent a number for them — and you should ask any vendor, Ferra and SteelFlo included, the same question in a demo: "Show me exactly what the reviewer sees, and show me a member the AI got wrong."
Which tool fits which shop?
| Your situation | Better fit |
|---|---|
| Want to test on your own drawings today | Either; both offer a free start |
| Any non-US standards (EN, BS/IS, AS/NZS, GB) or cold-formed work | SteelFlo |
| Plates, angles, channels, HSS, and other misc-metals-heavy packages | SteelFlo (test both) |
| Need connection detection in the takeoff | Either |
| Want bid pipeline and go/no-go guidance in the same tool | Ferra |
| Frequent revision cycles where automated Rev-diffing saves real hours | Ferra |
| Want 3D visualization from 2D drawings | Ferra |
| Run Tekla PowerFab or need IFC output | Ferra |
| Fixed budget, need a known price before signing up | SteelFlo |
Plenty of shops will demo both. That's the right move — the two products overlap on takeoff but diverge enough on workflow that your team's habits should decide it. For the broader landscape beyond these two, our steel takeoff software comparison covers the full field, and the Ferra alternatives roundup narrows it to the closest substitutes.
Frequently Asked Questions
Is Ferra free to try?
Yes, as of its 1.5 release in September 2026. Ferra now has open signup ("Start for free") with no demo required, and a demo is still available if you want one. The free tier's limits aren't published, and neither is paid pricing. SteelFlo also gives you 3 free takeoffs on signup with no card and no demo, and publishes every plan price.
Does Ferra support international steel standards?
Ferra's public materials describe a North American structural steel focus, and we found no published claims of support for EN, BS/IS, AS/NZS, or GB sections. If your work touches international standards, ask directly in the demo — and test with your own drawings. SteelFlo detects and validates against six standards (AISC, BS/IS, EN, AS/NZS, GB, CFS/SSMA) with 4,700+ sections.
Can you try SteelFlo without a demo call?
Yes. Sign up, upload a PDF, and run a takeoff — the first 3 are free, and there's no sales call anywhere in the flow. If you want a walkthrough, support is available, but it's optional rather than a gate.
Is Ferra the same company as Beam AI or SketchDeck LIFT?
No — they're three separate companies. Beam AI operates more like a takeoff service with a large customer base, SketchDeck LIFT is a steel-specific tool with connection detection and Tekla PowerFab export, and Ferra is a newer bid-intelligence and takeoff platform. We've compared SteelFlo against Beam AI and SketchDeck LIFT separately.
If you'd rather judge with your own drawings than another vendor page, start your 3 free takeoffs — no demo call, no card. Try Ferra's free start too and compare on the same drawing. Upload a PDF, review every boxed member, and export the BOM. You'll know in an afternoon whether it fits your shop. More on the full workflow at our steel takeoff software page.
