Steel – Services

premium services for steel materials

We offer material cutting, packaging, product marking, mill edge trimming of coils/sheets, brushing and mill scale removal from sheet surfaces. Transportation is naturally provided.

MATERIAL CUTTING

From coil to sheet – service centers have lines for cutting coils transversely or longitudinally, surface brushing lines, packaging and label marking. Intelligent control systems ensure precise monitoring of all production and logistics flows, transparency and product traceability. Cutting lines process coils from 0.4 mm to 25 mm thickness and offer customers sheets of all sizes, including custom formats (see table of options on page 1).

The advantage is a sheet with a perfectly flat surface, with elimination of sheet waviness, with a guarantee of the highest quality products, as well as time and budget savings for the end customer, who receives a product ready for further processing.

PACKAGING

Packaging of sheet bundles is handled by our suppliers with maximum attention to ensure:

  • safety of operators who handle bundles and use the sheet
  • preservation of surface quality and sheet flatness

WE OFFER THREE TYPES OF PACKAGING:

Standard packaging, already included in the material price

  • sheets stacked on top of each other with wooden spacer blocks loosely placed
  • sheets bound in bundles with metal straps 19 x 0.8 mm, according to ASTM A700-5 standard
  • sheet bundles stacked on top of each other with wooden spacer blocks measuring 35 x 60 mm loosely placed, i.e. not attached to the sheets, arranged in the direction of sheet width, one per running meter of bundle length.
  • bundles with unit weight from 2 to 4 tons depending on sheet thickness and length
  • suitable for thicker hot-rolled sheets

Optional packaging for a fee

  • sheets stacked on wooden spacer blocks strapped into a bundle
  • sheets bound in bundles with metal straps 19 x 0.8 mm, according to ASTM A700-5 standard
  • sheet bundles stacked on top of each other on wooden spacer blocks 65 x 80 mm, grooved on the support side and attached to the sheets, one block per running meter of bundle length, which for this type of packaging cannot exceed 6000 mm
  • bundles with unit weight from 2 to 4 tons depending on sheet thickness and length

Optional packaging for a fee

  • sheets stacked on wooden pallets strapped into a bundle
  • bundles stacked on pallets composed of transverse and longitudinal wooden elements nailed together and tied to the sheets with metal straps 19 x 0.8 mm, according to ASTM A700-5 standard
  • bundles with unit weight from 2 to 4 tons depending on sheet thickness and length
  • pallet production may require additional time compared to other types of packaging

Protection of bundles with PVC film, only on request and for a fee*

  • on request, sheets can be protected with gray PVC film
  • depending on sheet thickness, the PVC film will be wrapped spirally around the bundle, or stretched over the top of the bundle and secured with metal pallet straps

* Cold-rolled sheets, blanks and coils, thinner gauges up to 5 mm and coated surfaces are also supplied strapped on a wooden pallet with protective PVC, where special packaging is included in the price of the coil or sheet. Your sales representative will alert you to these cases, as only one of the suppliers does not charge for them.*

Notes on packaging:

  • standard bundle weight ranges from 1.5 to 4 tons depending on sheet thickness, width and length
  • orders for particularly short sheets or light bundles may be charged due to higher production or packaging costs

LABEL - PRODUCT MARKING

Product marking is a fundamental process to ensure traceability of sheet products at all stages of their existence. Service centers use a marking system that enables real-time product monitoring, reporting all information in the factory so that all operators can optimize handling flow.

The main traceability tool used in the marking process is a barcode on each adhesive label attached to each sheet bundle. Lines in the production process are equipped with an automatic labeler connected to the database of received orders in the information system.

Each bundle has an adhesive label with the following standard information:

  • supplier data
  • client data
  • destination address
  • material quality
  • sheet thickness and dimensions of sheet, coil or blank
  • material standards
  • heat number
  • type of material testing (EN10204-3.1/2.2…)
  • bundle weight
  • bundle ID number
  • manufacturer’s order confirmation number
  • customer order number
  • number of sheets in the pallet

Notes on product marking:

  • based on a written request and agreement with the manufacturer, the label text can be customized according to customer needs, which must be stated in the order
  • ensure that the requirement for customization of bundle marking is clearly stated in the manufacturer's order confirmation

IN CASE OF ANY SPECIFIC NEEDS, CONTACT YOUR SALES REPRESENTATIVE AND AGREE ON THEM.

PRODUCT MARKING ON SHEET/COIL

The service center can perform sheet marking modifications based on specific client needs as a customized service. There are various types of marking and depending on the one chosen, the result obtained can be permanent or erasable, naturally without damaging the steel.

We offer two types of steel sheet marking:

- ink marking, erasable (sheets, coils, blanks)

Using special ink printers located on cutting lines, each sheet is marked on one side and longitudinally with a variable number of characters and/or graphic symbols. Ink marking typically contains the following information:

  • manufacturer’s name or purchasing company name
  • quality of the supplied steel
  • heat number assigned by the steel mill and also stated in the EN10024-3.1 certificate, which is a unique identifier indicated on the coil by the manufacturer, allowing each sheet to be associated with the certificate.

These standard markings can be integrated or replaced at the customer’s request. The ink used for marking can be erased using common solvents/thinners and does not affect the physical properties of the material; however, if special surface treatments are anticipated, such as painting, ink marking may be contraindicated.

Notes on product marking:

  • the request for non-marking of sheets or for marking them with special data must be submitted by the buyer in writing in the order sent

- stamping

  • physical marking that permanently engraves a series of up to 38 characters, numbers and spaces on one side of each sheet.
    The depth of the cut is designed to ensure that the material’s resistance will not be affected and the parameters specified in EN10163 will not be exceeded.

MILL EDGE TRIMMING OF COIL/SHEET*

Sheet/coil edge trimming is performed by removing part of the product edge to reduce the width of sheets according to customer needs. The requirement for trimmed edges must be stated in the material order, as it is not always done. The result of edge trimming ensures product uniformity in the series for standardized serial production.

Benefits obtained from proper trimming procedure are:

  • product customization
  • waste reduction in subsequent processes
  • greater satisfaction for end users

Note*:

  • the request for non-marking of sheets or for marking them with special data must be submitted by the buyer in writing in the order sent
  • service centers offer trimming service on coils with maximum thickness of 6 mm and up to 2130 mm width
  • it is possible to reduce sheet width by up to 70 mm from the initial coil width
  • trimming necessarily involves reducing the width of sheets compared to the initial width of the coil with unprocessed edge; the minimum width guaranteed after edge trimming typically corresponds to the nominal coil width minus a deviation of 6 times the thickness of the coil itself; e.g. for a 3 x 1500 mm coil, the minimum guaranteed width after trimming will be 1482 mm, i.e. the minimum guaranteed width of a coil with raw edges according to EN10051 (1500 mm) minus the thickness of 3 mm multiplied by 6

WARNING:
Suppliers provide edge trimming service exclusively on client request/order, the service is charged, as it involves additional labor and waste costs.

BRUSHING AND MILL SCALE REMOVAL FROM SHEET SURFACES

Attention to detail and surface appearance are elements that characterize quality suppliers. These surface treatments are specially performed on request to remove all impurities, steel dust (mill scale) and micro-flakes, so that the sheet obtains a smooth, homogeneous surface suitable for finer production processes.
Mill scale is formed during hot processing of steel products and appears as a dusty patina or micro-flakes created by a combination of ferric oxide, magnetite and hematite.

Cutting lines at our suppliers are equipped with multiple brushing and mill scale suction sections, through which the mill scale naturally present on the surface of steel sheets is removed by the action of rotating brushes with carbon fibers. It is suctioned by a special system, collected in special containers outside the production hall and completely recycled.
Sheets after mill scale removal have a surface particularly suitable for laser cutting at a fraction of the cost of pickling.

This surface treatment can represent an alternative to pickling or grinding of steel sheets:

  • it does not require oiling, because brushing of sheets preserves the natural protective layer of surface oxidation, which pickling completely removes;
  • it does not require the costly oil removal process that must be performed before surface treatment of pickled steel sheets;

Note:

  • Service centers provide mill scale removal and surface brushing on request/order and for an additional fee

OPTIONAL PROCESSES

In addition to cutting steel sheets to size, service centers provide additional services on request, using external verified and reliable partners. These include:

  • coil weight reduction
  • pickling of black coils
  • re-certification of coils and sheets according to EN10204-3.2 with Lloyds, TUV, Rina
  • ultrasonic tests according to EN or ASTM regulations
  • sandblasting and primer coating of steel sheets
  • toughness test (Charpy test) in SINAL certified laboratories

These services are supplied on request, subject to minimum order quantities and involve additional costs and time compared to sheet cutting deadlines.

FOR MORE INFORMATION, CONTACT YOUR SALES REPRESENTATIVE.

LOGISTICS

The logistics center of each service center spans an area of 15 to 25,000 m², which is completely covered to ensure safe and protected storage of coils and sheets ready for loading, as well as optimal management of finished products during transport.

Management and movement of raw materials and finished products is carried out using latest-generation overhead cranes with high maximum capacity for heavy loads. Movement of smaller products such as blanks, strips and sheets is carried out using forklifts.
