It's 2026.
Why is your steel software still stuck in 2005?

Two apps. One brand. Pick the one that matches the work you're doing today.

Built For

The entire steel project chain of custody.

SteelCaller serves three audiences from a single source of truth. Each role sees what they need, on the device they already carry.

Fabricators
Stop answering the same phone call forty times a day.
Export IFC, KSS, and NC1 from your modeling software. Upload once. Your field crew finds their own piece marks, bolt specs, and location data without calling the shop. Revisions propagate automatically — no reprinting, no faxing, no lost updates.
Erectors & Field Crews
Set iron faster. Hands-free lookup on any phone.
No paper drawings in the cab. No torn sheets on the deck. Search by piece mark, grid line, or elevation. Tap the mic and say "Call 130B4" — the AI voice reads back the section, bolt count, and connection info while you stay hooked into your PFAS.
General Contractors
Know what's set, what's pending, what got revised.
Open the same field app from your trailer. See erection progress without waiting for Monday's report. Every revision alert is acknowledged before the piece goes up — you have a digital trail showing the crew saw the change and confirmed it.
Revision Management

When drawings change mid-project, nobody gets hurt.

Upload a revised IFC and SteelCaller automatically compares it to the previous version. Every changed piece gets flagged with the exact reason. New pieces appear with a green NEW badge. Deleted pieces stay visible with a red DO NOT SET banner. Field crew must tap Acknowledge on the revision banner before marking the piece complete — nothing slips through.

Revised
130B4 — Section changed
W18x35 → W21x44 · Weight 1,219 lbs → 1,400 lbs. Red banner shown; Acknowledge required before Mark Complete.
New
299X1 — New piece added
Green banner + NEW badge appears in the list. "Verify location before setting" warning shown on piece detail.
Deleted
101C1 — Removed from model
Piece stays visible in the list with strikethrough. Mark Complete button replaced with disabled "DO NOT SET" — cannot be accidentally completed.

How It Works

Upload once. Live in minutes.

No IT department. No custom integration. No training. If you can export files from your modeling software, you're ready to deploy.

Every job
Features

Made for the deck, not the desk.

Every feature solves a specific pain point. Designed with input from superintendents, connection engineers, and ironworkers who use it on the iron.

Hands-Free Voice Lookup
Tap the mic once, listen for 60 seconds continuously. Say "Call 130B4" and the AI reads back the section, weight, and connection info. Works while wearing gloves 60 feet in the air.
Revision Alerts with Acknowledgment
Upload a revised model — every changed piece gets flagged with the exact reason (section, bolts, connection, etc.). Two-step confirm: Acknowledge, then Mark Complete. No mis-sets.
Full Bolt Specifications
Stop sending crews up with the wrong bolts. Every connection shows exact count, diameter, grade, and washer requirement — pulled from your KSS file and cross-verified against NC1 hole counts. Left end and right end listed 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. Pulled from your model data, not estimated.
English & Spanish
Every label, button, and voice readout is available in both languages. One tap to switch. Settings are saved per phone so each crew member sees their preferred language on every session.
Live Progress Tracking
Field crew marks pieces complete as they set them. The Sequence screen shows percent complete by elevation. GC and superintendent open the same link and see the same data — no daily status calls.
Shop Drawings Built In
Upload your shop drawing PDFs once — SteelCaller indexes them by piece mark automatically. Tap any mark in the field app and the matching detail sheet opens in a zoomable viewer. No more paper drawings on the deck, no more digging through a tablet full of PDFs.
Erection Drawings With Location Finder
Upload your erection sheets — framing plans AND brace elevations. SteelCaller reads the grid system automatically and maps every piece mark to its exact location. Search "130B4" in the field and the roof framing plan opens with a red ring showing the beam between grids 7 and F. Search a vertical brace and the brace elevation opens with the piece highlighted between the correct columns.

Plans AND elevations — vertical braces get routed to elevation sheets, not just plan views where they'd be invisible. No more walking back to the trailer to check which sheet a piece is on.
The App

Every screen, purpose-built.

Designed for high contrast, thumb-only navigation, and one-handed use. Works on any phone with a browser.

Search screen with mic button, revision alerts, and piece mark list
Search & List
Instant text search. Filter by type, elevation, sequence, or revision status.

Section, grade, weight, bolt specs, connection ends, grid location — on one screen.

Alerts Screen
Separate sections for Revised (with ACK status), New Pieces, and Deleted — tap any to jump to the piece.
Shop drawing detail sheet opened in the field app PDF viewer
Shop Drawing Viewer

Hands-Free Operation

The app talks. You listen.

Tap the orange mic button once and the app listens continuously for sixty seconds. Say "Call" then the piece mark. The AI voice reads back what you need to know, then waits for the next command. No typing. No pinching. No gloves off.
