SteelFlow

SteelFlow is a manufacturing execution system for steel-fabrication shops. It traces every part, weld and heat from the Tekla model to erection on site, and the shop floor keeps working offline.

For steel-structure fabricators (sheds, industrial halls and buildings) with 20 to 500 people. Planners, shop-floor operators, QC inspectors, procurement and managers each work in the system in their own role. The client's representative and the third-party inspector can also get their own read-only access.

Why SteelFlow

• Full traceability: From a part to its heat, mill and certificate (MTC), and on to its WPS, welder, NDT and coating. This is what the client's inspector asks for.
• Final Book in one click: A signed MRB/Final Book PDF for one deliverable, or for the whole project in Persian, English or Arabic, with a drawing register and the stamped drawings merged in. It is built from records that already exist, so nobody assembles it by hand.
• Two-way with Tekla: The Tekla desktop app (Tekla 2016 to 2026) sends the BOM on every save, colours the model by production status and locks built parts in Tekla.
• AI assistant (optional): It drafts phasing, truck loads, the weekly release, purchase orders for shortages and ITP drafts as proposals you preview. Nothing is saved until you accept it. It is off by default.
• Works offline: The station tablet keeps scanning without network and syncs later.
• Live 3D model: Every member of the Tekla/IFC model is coloured by its real production status.
• Quote to claim: Tenders, contracts, variation orders, progress claims, job costing and export to the accounting package.
• Trilingual: The UI is in Persian, English and Arabic, with full RTL. The Final Book is issued in the client's language.

Every capability, area by area

Engineering

• Tekla plugin and CSV/Excel BOM import, with BOM versions. Each new revision opens a change-impact review, which also shows renumbered marks, before it is confirmed.
• Tekla desktop app in three languages: auto-send on save, production-status colours on the model, locking built parts, Show in Tekla, RFIs and transmittals from the selection, and an AI model review with a clash check.
• 3D model viewer (IFC), coloured by live status. Click a member to open its part. A shape view for a single part, with 2D, 3D and the section.
• Drawing register with versions. Clients can mark up drawings in the browser.
• Transmittals (IFA, IFC, for information) with A/B/C approval by the client.
• RFI / technical query log, tied to a part, assembly or drawing. Clients can answer it themselves.

Commercial

• Cost-rate table and tenders, with quote versions and win/loss tracking.
• Contracts with milestones, retention, variation orders, and progress claims certified by tonnage or by %.
• Job costing: actual material, labour and direct cost against the quote and the contract, with cost to complete (CTC), forecast at completion (FAC), margin and a tonnage S-curve.
• Accounting hand-off: certified claims, supplier invoices and POs go out as one CSV/Excel voucher file per period.

Supply & stock

• Supplier register. Purchase demand is generated from the BOM. Purchase orders, goods receipt and invoices are matched three ways.
• Material lots with heat numbers and MTC PDFs. A heat can be quarantined, which raises a containment NCR on every affected part.
• Stock is reserved when work is released and consumed at the cut scan.
• 1-D nesting on stock lengths, with tracked remnants.

Planning

• Build proposals: what can be built now, and which material is missing. Work is released by assembly kit, and a shortage becomes a purchase request.
• Planning assistant (optional): proposed phasing, truck loads and weekly release, previewed before anything is saved.
• Finite-capacity schedule: station capacity and a shift/holiday calendar, a Gantt per deliverable, station load, and due-date risk.

Shop floor

• Station screen for tablets: scan a barcode label, then Start and Finish work. Real labour time is recorded per operation. Works offline.
• Kiosk: type or scan a mark to see the part's drawings, WPS, welder and the procedures to read. Search ignores letter case.
• Workflow designer with 12 ready templates and a standard time per step.
• A4 barcode label sheets for parts.

Quality

• QC gates, NDT/UT and DFT. Weld logs check WPS and welder qualification, with expiry alerts for welder certificates.
• NCR, then CAPA, then MRB disposition (scrap, repair or rework). The disposition moves the part's status.
• ITP with hold and witness points, signed by the client and the third-party inspector.
• Controlled documents (procedures, work instructions) with read receipts.

Delivery

• Shipments with a packing list, plus delivered and erected status. An open NCR, QC, NDT, DFT, MTC or ITP item blocks dispatch unless a manager records a concession.
• Final Book (MRB): a signed (prepared, checked, approved) PDF per deliverable, or for the whole project in Persian, English or Arabic, with a drawing register and the stamped drawings. The client gets a 30-day share link with no account needed.

Management

• Live dashboard: WIP tonnage, station load, readiness per deliverable, cycle time, labour hours, and who is working on what right now.
• Excel/PDF export of every list. Daily or weekly PDF reports by e-mail.
• Notifications: in-app, e-mail, SMS, and a Telegram/Bale-compatible bot. Outbound webhooks.
• Full activity log: who changed what, when, and from what to what.
• Roles: planner, operator, inspector, manager, procurement and admin. External roles: client and third-party inspector, each seeing only their own projects.
• Client and third-party inspector portal: part summary, Final Books, MTCs, ITP evidence and an awaiting-me list.
• Column filters on the tables, and each language's own calendar (Jalali in Persian).
• Built-in Help Center and glossary, in the same three languages. Where work is blocked, Ask the assistant explains why and what to do (when the assistant is on).

Technical facts

• Web app plus an installable PWA on tablets and phones. Nothing to install on the server side for users.
• Multi-tenant SaaS: each company's data is isolated by database row-level security. An on-premises install is possible.
• Tekla Structures plugin and desktop app (.NET, Tekla 2016 to 2026, auto-updating) and IFC import.
• Optional AI assistant, off by default, with a monthly usage cap and settings per role.
