Unser Service für Sie-UnionStahl GmbH

Our services for you

Our highly-qualified and committed employees check your enquiries for plates, flame-cut parts and further-processed components in respect to technical feasibility, and are pleased to offer advice on possible alternatives (quality, tolerances, design and dimensions), if required.

Typical questions, we look into here, include:

Is there actually a solution for the planned application?

Is there a better technical solution?

The specifications or delivery details enclosed in the enquires are processed and commented on. We endeavour to cover all possible requirements (insofar as technically feasible). Otherwise, we are pleased to help in an advisory role. Additionally required properties can be verified subsequently.

We were one of the first stockists to utilise barcode technology to identify and track our products.

That allows us to update you about material properties or the order status at any time.

We monitor compliance with the delivery schedules during the further course of the project. We organise transportation by truck, rail, ship or aircraft. A complete and timely provision of the order documentation is part of the service scope.

Unser Service für Sie rund um Grobbleche und Stähle

Our services include

  • Reviewing specifications and delivery instructions
  • Project management
  • Storage of custom metal components (heavy plates, flame-cut parts, machined parts)
  • Blasting
  • Priming
  • Pickling and oiling
  • Marking with tube lettering or stencil
  • Packaging according to customer requirements, e.g. pallets treated according to IPPC standard, shrink wrap
  • Transport handling and shipping, including container stowage in the harbour
  • Preparation of documentation according to customer requirements

Further services: Comprehensive quality assurance processes

  • Ultrasonic testing in accordance with European standards, ATSM/ASME 435 and 578, and customer specifications
  • Dimensional and tolerance testing using:
    • conventional measuring equipment: Calipers, inside micrometers, limit plug gauges, depth calipers
    • tactile measuring arm: direct contact measurement using a contact-active probe on a measuring arm (3 m range), high absolute accuracy, less suitable for area measurements
    • optical detection: contactless measurement by means of absorption and reflection, mounted on a measuring arm (4.5 m range), detects entire surfaces, precise measurement of distance, shape, size and surface roughness, 3D data model creation possible
  • Initial sample inspections following VDA guidelines
  • Re-stamping authorisation for DNV, LR EMEA, BV
  • Special approvals by TÜV, DNV, LR, ABS, BV, etc.
  • Mechanical-technological testing by partner laboratories with daily collection of sample coupons, in detail:
    • Proof of chemical properties (spectral analysis, PMI)
    • Proof of mechanical properties (e.g., tensile test, notched bar impact test, hardness test, weld-on bending test, tensile test in thickness direction, bending test)
    • Mechanical properties testing after simulated annealing (PWHT)
    • Purity determination (macrosections and microsections), grain size determination
  • Dye penetrant and magnetic particle testing

Additional material tests are carried out by our appropriately qualified specialists or independent testing laboratories.
