Our products

BHH Mikrohuta produces high-quality cold drawn wires and bars in stainless, acid-resistant, heat-resistant and resistance grades.

The offer includes round and flat products made by cold forming

To meet all customer needs during the production process, the wires are heat treated in a protective atmosphere.

Mikrohuta offers the production range as follows:

  • Round wire in range:  dia 0.2-16.0mm
  • Round bars: dia 2,5-5mm
  • Flat wire in range: thickness: 0,2-2mm, width: 0,9-7mm

 

Grades

Mikrohuta produces   bars and wires  made of austenitic steel in  chromium-nickel, chromium-nickel-molybdenum  grades and  ferritic steel  products of chromium contain.

Surface standards

Mikrohuta offers a diverse range of wire and drawn rod surfaces:

  • glossy surface
  • bright surface
  • clear, clean surface (washed)
  • surface with the bonder applied (so-called bonderized surface)

Types of Packaging 

Depending on the  diameter of the wire,  different packaging methods are used by Mikrohuta.

Spools DIN 125 - DIN 250 (0,2 mm - 1,2 mm )

Average amount (weight) of wire on spool:

DIN 125 - 3 kg
DIN 160 - 5 kg
DIN 200 - 13 kg
DIN 250 - 20 kg

Spools arranged horizontally on pallets, wrapped in foil or packed in a cardboard box placed on a pallet.

Coils

Coils 50 ÷ 500 kg are packed on a pallet, stapled together with the pallet, internal diameter from 400 ÷ 600 mm external diameter max 1000 mm. Coils wrapped in foil.

Metal former

Quantity from 300 to 1000 kg rolled "from above", rosette laid on metal former. Additionally material can be wrapped in foil.

Foil-wrapped bundles - drawn bars

Drawn bars in all dimensions are packed in foil-wrapped bundles. Packing of bars on a wooden board or in a fumigated box is also possible upon request.
