Paper drawings on a job site get wet, torn, and left in the truck.

Ironworkers call the office to check bolt specs. Supers dig through submittals to find the section size. Foremen don't know a piece is revised until the crane is already in the air. SteelCaller fixes all of it.

One Tap
Every piece mark, bolt spec, elevation, and revision status — instantly on any phone. No app download, no login, no training required.
"Call 52B1"
Hands-free voice lookup reads the entire piece out loud. Gloves on, both hands on iron, the information comes to you.
EN / ES
Full English and Spanish support — the AI voice speaks in whichever language the ironworker prefers. Every label, button, and voice command bilingual.

We Build the App
Our server parses all three files, merges the data, calculates assembly weights, and generates your project app. Typically 2–5 minutes.
Auto-processed
Share the Link
You get a unique URL. Text it to the foreman, email it to the GC, post it in your job chat. Anyone with the link can open it — no account needed.
No login for crew
Field Crew Uses It
Ironworkers open it on their phone. Search any piece, hear the bolt specs read aloud, mark it complete. Works 60 feet in the air, gloves on.

Features

Everything theField Needs.

Designed with 30+ years of steel detailing experience. Every feature exists because an ironworker or superintendent actually needs it.

Hands-Free Voice Lookup
Say "Call 52B1" and the AI voice reads back the section, elevation, bolt specs, and any revision or camber warnings. Works while wearing gloves 60 feet in the air. Wake word always listening.
Revision Alerts
When you upload a revised model, SteelCaller automatically compares it to the previous version and flags every changed piece with a red REVISED banner showing exactly what changed. No guessing.
Full Bolt Specifications
Every connection end shows the exact bolt count, diameter, length, grade, and washer requirement — pulled from your KSS file and verified against your NC1 hole counts. Left end and right end shown separately.
Accurate Crane Pick Weight
Full assembly weight calculated from dimensions — main member plus every shop-welded plate, angle, clip, and stud. Not just the bare section weight. Calculated from your actual model data, not estimated.
English & Spanish
The entire app — every label, button, and AI voice readout — is available in English and Spanish. One tap to switch. Settings saved per phone so each crew member gets their preferred language every time.
Live Progress Tracking
The field crew marks pieces Complete as they go. The superintendent and GC see the erection sequence progress in real time — what's done, what's pending, what's been revised. No more radio calls asking for counts.
Hands-Free Operation
