The product

One European supplier. One purchase order. Castings, weldments and machining.

Stratosteel acts as the prime contractor and single point of accountability. Production is executed through our qualified Central European manufacturing network under one commercial, technical and quality-management system. We call this product ONE PO. You do not buy machine hours from us. You buy a finished casting, forging, weldment or machined part, delivered with its documentation, on one purchase order with one responsibility. We carry engineering, manufacture, verification and delivery across a certified European network. Send a drawing, an engineer answers within 48 hours with feasibility, route and questions.

The problem it removes

A heavy part crosses four trades. Someone must own the interfaces.

A buyer in heavy industry has three options. Contract four suppliers and carry four schedules, four quality interfaces and a four-way blame loop. Build capacity in-house and carry the capital. Or choose one contracting party that holds engineering, quality, schedule and responsibility. For heavy parts in Europe, the third option is what we sell.

Option 1

Four suppliers

Foundry, forge, weld shop, machine shop. Every interface is your risk, every delay is your meeting.

Option 2

Own capacity

Capital on your balance sheet, capacity you must keep loaded, trades you must hire.

Option 3

ONE PO

One contract for the finished part. The interfaces are ours. The responsibility is ours.

What one purchase order covers

  • One contract with Stratosteel s.r.o., one invoice, one confirmed date
  • Engineering review of the drawing before anything is cut
  • The manufacturing route: casting, forging, welding, machining, as the part needs
  • Verification: certificates read line by line, parts measured independently
  • Documentation: EN 10204 3.1 standard, 3.2 with named third party on request, CMM report, NDT protocols, heat treatment records
  • One warranty holder and one addressee for any NCR
  • Origin verified and disclosed per part. EU first. Where a non-EU route applies, we say so before you order.

The producing plant confirms capacity and date before we confirm them to you. What your PO requires of us, our order requires of the plant.

Two honest limits

What one purchase order does not cover

Construction scope on site stays with a contractor of record. We cover the steel scope: parts, structures, machining, documentation. And we do not ask to be your single source on day one. The entry is a pilot order of low criticality. Scope grows with delivered performance, not with slides.

On partners: the material certificate always names the producing works, so we do not sell anonymity. We sell management. We manage the plants, audits at the producing works are arranged through us, and the full plant list with certificates is on the table at qualification.

What one PO looks like when it lands

Heavy welded steel frame with machined bores and fitted pin, finished on one order
Cut, welded, bored, fitted — one order
Serial cast steel components staged on transport frames after inspection
Serial castings, staged for machining
Finished machined steel hubs packed in an export crate ready for delivery
Finished, crated, one delivery

Forming, joining, machining, packing: four steps, three pictures, four suppliers you did not have to find. On your side it is one purchase order, one quality owner, one delivery date.

What happens next

From drawing to delivered part.

WITHIN 48 H

First technical answer

An engineer replies with feasibility, the proposed process route and open questions. Not an autoresponder.

3 TO 7 DAYS

Firm quote

Price, lead time, documentation scope. Issued once the production unit is confirmed, so the number holds.

ONE PO

One responsibility

Manufacture, verification, documentation and delivery under one contract with Stratosteel s.r.o.

DELIVERY

Verified part, full file

Certificates, CMM report, NDT protocols, traceability to heat number. Then we talk about the next part.

What we need from you: drawing, material, quantity, target date. What we do not do: quote blind, or start without an agreed documentation scope. Outside our envelope, we say so in the first reply. The full process →

Straight answers

Questions buyers ask before placing one order

Can one European supplier take responsibility for castings, weldments and machining on a single purchase order?
Yes. Stratosteel acts as the prime contractor and single point of accountability: one contract, one invoice, one confirmed date, one warranty holder. Production is executed through our qualified Central European manufacturing network of certified partner plants under one commercial, technical and quality-management system. You place one purchase order for the finished, machined and documented part; the interfaces between foundry, forge, weld shop and machine shop are ours to manage.
What exactly does one PO with Stratosteel cover?
One purchase order covers the finished part: engineering review of your drawing, the manufacturing route across casting, forging, welding and machining as needed, verification and measurement, the documentation package and delivery. One contract, one invoice, one confirmed date, one warranty holder, one name that answers. You do not coordinate foundries, forges, weld shops and machine shops. That is our work.
Who actually makes the parts if Stratosteel owns no plants?
A certified European production network of long-term partner plants makes the parts. Stratosteel is the contracting party and the responsibility holder: we place the work, confirm capacity with the producing plant before promising a date, verify quality at the moments that decide a part, and carry the contract. The material certificate always names the producing works. We manage the plants. You audit through us.
How is quality protected across plants we never see?
Certificates are read, not filed: heat numbers, element percentages and revision states are checked line by line. Parts are measured independently on the critical end of the tolerance budget: WENZEL LH 108 CMM, Mitutoyo BHN706, FARO laser tracker. On critical parts our engineers are present at the pour, controlled cooling, heat treatment and first piece. On request, a named third party verifies per order and is billed transparently.
What documentation arrives with an ONE PO delivery?
EN 10204 3.1 material certificate as standard, 3.2 with a named third party on request. Dimensional report with CMM trace. NDT protocols per specification: UT, MT, PT in the network, RT via an ISO 17025 laboratory. Heat treatment records. Traceability to heat number, pour date, operator and inspector. melt-and-pour origin stated in every quote, EU-only routes available on request.
What does ONE PO not include?
Two honest limits. Construction scope on site stays with a contractor of record; we cover the steel scope. And we do not ask to be your single source on day one: the entry is a pilot order of low criticality, and scope grows with delivered performance.
How do we start without risk?
Send 1 to 3 drawings to rfq@stratosteel.com. Within 48 hours an engineer sends feasibility, the proposed route and open questions. Firm quote in 3 to 7 working days once the production unit is confirmed. Then a pilot order on one part number with full documentation. You judge the quote first, the parts second.

One line to remember

The PO is paper. The delivery is metal. The responsibility is what we carry between them.

Every envelope behind this product is on the capability sheet, labeled demonstrated or qualified. Every claim of verification is explained on the verification page. Nothing here asks for your trust. It asks for one drawing.

Start with one part.

1 to 3 drawings to rfq@stratosteel.com or the form. First technical answer within 48 hours. Firm quote in 3 to 7 working days once the production unit is confirmed.
