Integrated mills
Blast-furnace and BOF producers with hot strip, cold rolling and multiple coating lines. They buy Plant and expand to Enterprise, usually starting on the galvanizing line.

Who buys
Three profiles, one problem
Different scale, same losses.
EAF mini-mills
Flexible producers under acute energy pressure. They start with Yield & Energy on the hot strip mill and expand into gauge and shape.
Re-rollers and aluminium
Tight-margin operations where a point of prime yield is the whole year. They buy Line, prove it in a quarter, and add the second line.
In their words
Three deployments, in detail
The specifics behind the logos.
NordStrip Steel — tandem cold mill
A five-stand tandem mill running automotive and appliance grades with chronic tail-end off-gauge and an ageing roller population. Steelira went in on Roll & Gauge, shadow for eight weeks, assist for six, bounded autonomy since.
- Off-gauge metresDown 38% per coil at head and tail.
- Chatter eventsTwo prevented in the first quarter, each historically a shift of lost production.
- Acceptance rate94% of recommendations approved unmodified before promotion to auto.

Ferrata Group — galvanizing line
A continuous galvanizing line over-coating systematically to stay clear of spec, with property misses on high-strength grades. Temper & Coat plus Yield & Energy went live within a quarter.
- Coating spendCoating weight held just inside spec instead of comfortably above.
- Prime yieldUp 1.7 points on the line against the agreed baseline.
- Reheat gasDouble-digit reduction at constant throughput.

Aurum Flat Rolled — hot strip mill
A hot-strip mill where the two people who could set up hard automotive grades were both within three years of retirement. Schedule & Flow and the twin were deployed as much for succession as for yield.
- Setup craftCaptured per grade family, versioned, and explainable to the next generation.
- Property first-passFewer downgrades on high-strength grades against the property window.
- Passes per coilReduced on several grades through TMCP path optimisation.

Voices
What they tell their peers
“We ran Steelira in shadow for eight weeks on the tandem mill. It called eleven of the twelve off-gauge tail events before our AGC reacted. That was the moment the argument ended.”
“Our best roller retires in two years. Steelira is the first system that captured how he sets up a hard automotive grade — and then explained why, with the coil history to back it.”
“Prime yield moved 1.7 points on the galvanizing line and reheat gas fell double digits. Nothing else we bought this decade did both.”
Onboarding
What the first 90 days look like
Every customer runs the same sequence. Predictability is the point.
- STEP 01
Week 0–2
Connector mapping, edge node install, network and OT review signed off.
- STEP 02
Week 2–8
Shadow mode. Baseline measured, model scored against your coils, weekly review with your engineers.
- STEP 03
Week 8–14
Assist mode. Recommendations approved on the pulpit; acceptance rate tracked toward the promotion gate.
- STEP 04
Week 14+
Bounded autonomy on the loops that cleared the gate, with quarterly business review on measured outcomes.
Support
How we look after a live mill
A mill does not stop at 5pm and neither does the support model.
Named mill success engineer
One engineer who knows your line, your grades and your people, on Plant and Enterprise.
Metallurgist on the account
A real metallurgist reviews model behaviour on your grade families, not just a support ticket queue.
24×7 on Plant and above
Escalation paths that reach an engineer who can act, not a first-line script.
On-site for promotions
We are physically present for commissioning and every autonomy promotion.
Quarterly business review
Measured outcomes against baseline, presented to the people who signed the contract.
Roadmap influence
Enterprise customers shape the module roadmap through a formal council.

Security
OT-safe by construction
Steelira writes to mill equipment, so security and safety are product requirements, not paperwork.
SOC 2 Type IIISO 27001IEC 62443 alignedGDPRSSO / SAMLData residency
- Segmented OT pathEdge runtime sits in a Purdue Level-2/3 DMZ with signed, rate-limited write-back and hard setpoint clamps.
- Deterministic fallbacksEvery control loop degrades to the mill's existing Level-2 setup on watchdog timeout — the mill never stops because Steelira does.
- Grade-IP isolationRecipes, grade specs and coil histories are tenant-scoped, encrypted at rest with per-tenant keys, and never used to train another producer's models.
- Assurance-grade auditEvery perception, recommendation, approval and actuation is written to an immutable, exportable log keyed to coil ID.
Talk to a customer, not a salesperson
We will arrange a reference call with a design-partner plant director or rolling manager, under NDA, before you commit to anything.
