Overview

Construction and building-system parts range from structural steel and welded assemblies to façade brackets, anchors, stair and railing systems and sheet-metal cladding. Structural components placed on the EU market typically require EN 1090 certification and CE marking.

Türkiye is a major exporter of construction steel, fabricated structures and building products, with a large base of steel fabricators, aluminium extruders and sheet-metal shops.

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

Execution class, corrosion protection and delivery logistics shape most construction sourcing decisions. Stating the EN 1090 execution class, the coating or galvanising requirement and the project schedule helps identify fabricators that can deliver structural work to site on time.

Typical parts & components

  • Structural steel beams, columns and connections
  • Façade brackets, anchors and fixings
  • Stairs, railings and balustrades
  • Aluminium façade and window profiles
  • Sheet-metal cladding and flashings
  • Galvanised welded assemblies
  • Cast and machined fittings for glazing systems

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

Certifications & compliance

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

Supplier certifications

  • EN 1090 Typically required

    Required for CE-marked structural components.

  • ISO 3834 Common

    Welding quality system.

  • ISO 9001 Common

    Baseline quality system.

  • ISO 14001 Sometimes requested

    Requested for sustainable building projects.

Standards & regulations

  • CE Marking Typically required

    CE marking for construction products.

  • EN 10204 Type 3.1 Common

    Material certificate for steel.

  • AWS D1.1 Sometimes requested

    Structural welding code for US projects.

Quality & documentation

  • Factory production control certified to EN 1090 at the required execution class.
  • CE marking with declaration of performance for structural components.
  • Welding to ISO 3834 with qualified welders.
  • Material certificates to EN 10204 3.1.
  • Coating and galvanising thickness reports.

Typical tolerances & surfaces

  • Fabricated steelwork: tolerances per EN 1090-2 and the execution class.
  • Welded assemblies: tolerances per ISO 13920 classes.
  • Aluminium profiles: tolerances per EN 755-9 or EN 12020.
  • Hot-dip galvanising coating thickness per EN ISO 1461.

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 structures ship by truck or container; state the site location and delivery sequence so logistics are part of the planning.

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 fabrication), the specified material and grade, and certifications such as EN 1090 and 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

300 galvanised façade brackets — S355 — EN 1090 EXC2 — DAP.

  • The buyer uploads drawings for welded façade brackets.
  • Metraxio structures the requirement: laser cutting, welding, hot-dip galvanising, S355 steel, EN 1090 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

Is EN 1090 required for structural steel?

Structural steel and aluminium components placed on the EU market must be CE marked under EN 1090. The execution class depends on the structure.

Which execution class do I need?

EXC2 covers most buildings; EXC3 and EXC4 apply to more demanding structures. The designer defines it.

Can suppliers galvanise and paint?

Many offer hot-dip galvanising and painting in-house or through partners; list the finish in your requirement.

Are aluminium façade parts possible?

Yes. Extrusion, machining and anodising or powder coating of profiles 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.
