    Materials for coating

    On the continuous coil coating line, these materials may be painted: 

    Base material  Thickness (mm)  Band width (mm) Internal Ø (mm)  Packing (kg)  Min. order (kg)
     Al, Al alloys
    (EN AW 1050)
     0,4-2,0  600-1340  500/600 max  3500  700 - 1000
    FeZn, Fe
     0,3-1,2  600-1340  500/600 max  8500 1500 - 2000 

    All materials undergo a check-in and their quality is proved by a producer certificate.

    The most requested aluminium bands are bands AW-1050A with hardness of H24 and bands of aluminium alloys AW-3005 and AW-3105 with hardness of H22, H24, H26 and H28. 

    In the case of cold-rolled steel, the grade DC01 is used the most.

    The electroplated bands are most often supplied in grade DX51D, DX52D, DX53D, structural steel in grade S220GD, S250GD, S280GD, S320GD and with zinc-coating Zn 100 - 275.
