Overview

Renewable energy equipment ranges from large wind-turbine structures and machined hubs to solar mounting systems, inverter enclosures and battery-storage racks. Parts must withstand decades outdoors, often with strict corrosion protection and structural certification.

Türkiye has a sizeable wind and solar supply chain, producing towers, blades, castings, mounting systems and electrical enclosures for domestic and export projects.

On Metraxio you describe the part, attach drawings and state material, coating, certification and quantity. The platform structures the requirement and shows which facilities are a technical fit.

Renewable energy projects combine large structural parts with long outdoor service lives. Stating the coating system, welding requirements and part dimensions early matters because only some facilities can handle the size, weight and galvanising that wind and solar structures require.

Typical parts & components

  • Wind-turbine flanges, hubs and machined castings
  • Tower internals, platforms and ladders
  • Solar mounting structures and profiles
  • Tracker components and drive parts
  • Inverter and battery-storage enclosures
  • Busbars and electrical connection parts
  • Galvanised brackets and fixings

The processes, materials and requirements below are an editorial reference of what is typical for renewable energy programs — not a statement about facilities in the Metraxio network.

Common manufacturing processes

Typical materials & grades

Certifications & compliance

What buyers in this industry commonly ask suppliers for. Exact requirements depend on the program, customer and part.

Supplier certifications

  • ISO 9001 Typically required

    Baseline quality system.

  • EN 1090 Common

    For CE-marked structural components.

  • ISO 3834 Common

    Welding quality system.

  • ISO 14001 Common

    Often requested in renewable projects.

Standards & regulations

  • EN 10204 Type 3.1 Typically required

    Material certificate for metallic raw material.

  • EN 10204 Type 3.2 Sometimes requested

    For critical wind-turbine parts.

  • CE Marking Common

    CE marking for construction products and equipment.

Quality & documentation

  • Material certificates to EN 10204 3.1, or 3.2 for critical wind parts.
  • Welding to ISO 3834 with EN 1090 for structural components.
  • Corrosion protection to the specified environment class.
  • NDT of welds and castings.
  • Dimensional reports for large machined parts.

Typical tolerances & surfaces

  • Large flanges: flatness and bolt-hole position specified tightly.
  • Solar profiles: tolerances per the extrusion or roll-forming standard.
  • Welded structures: tolerances per EN 1090-2.
  • Galvanising and coating thickness per EN ISO 1461 or ISO 12944.

Sourcing from Türkiye

Türkiye combines a deep contract-manufacturing base with short routes into Europe. Industrial goods move between Türkiye and the EU under the customs union, so buyers typically avoid EU import duties on qualifying parts.

  • Many European destinations can be reached by road within several days; actual transit depends on origin, destination, customs handling and cargo.
  • Common delivery terms are EXW, FCA and DAP; Metraxio keeps the agreed Incoterm attached to the quotation and order.
  • Large renewable parts are often delivered to project sites; include site locations and delivery schedules.

How Metraxio qualifies suppliers

Every request is checked against each facility's structured profile before any supplier is invited.

  • Hard criteria: the required process (e.g. welding or heavy machining), the specified material and grade, and certifications such as EN 1090 or ISO 3834.
  • Missing data is not a rejection. If a facility profile does not yet state something, the result is "Needs More Information" rather than "Not Qualified".
  • No match yet? You can continue with Managed Sourcing and the Metraxio team runs supplier discovery for you.
  • Facility identities stay anonymous during the technical assessment.

Example project

How a typical request moves through Metraxio

10,000 solar mounting brackets — galvanised S355 — DAP to site.

  • The buyer uploads drawings for brackets and rails of a ground-mounted solar system.
  • Metraxio structures the requirement: stamping, forming, hot-dip galvanising, S355 steel and DAP delivery.
  • The fit assessment shows which facilities are qualified, which need more information and which do not match.
  • The buyer invites qualified facilities to a Supplier RFQ, or hands the job to Managed Sourcing.

Frequently asked questions

Can suppliers machine large wind-turbine parts?

Some facilities have heavy machining capacity for flanges, hubs and castings. Part size and weight are part of your requirement.

Which corrosion protection is typical?

Hot-dip galvanising for solar structures and multi-layer coating systems to ISO 12944 for wind parts.

Is EN 1090 required for solar structures?

Structural components placed on the EU market are typically CE marked under EN 1090.

Can I source battery-storage enclosures?

Yes. Sheet-metal fabrication, welding and powder coating of racks and enclosures are common.

Are supplier names visible during the assessment?

No. Facilities are shown anonymously during the technical assessment. Identities are shared as the engagement progresses.
