Coatings
- Metal coated steel sheets and coils
- Ruukkis metal coated steel products offer a combination of
high-strength and formable steels and corrosion resistance from the
coating
- Our extensive manufacturing programme enables you to combine
exactly the characteristics required for your application
18. Coatings
-
- The traditional zinc coating provides a good level of corrosion
protection for normal applications
- Galfan zinc-aluminium alloy coating
-
- This coating system provides clearly superior formability
compared with the traditional zinc coating
-
- Galfan is well suited for demanding deep drawing
- Galvannealed zinc-iron alloy coating
-
- The iron content of this coating gives Galvannealed coated
steels outstanding weldability. Adhesion on the matt surface is
excellent, creating a first class surface quality in the end
product
19. Coatings
- Colour coated steel sheets and coils
- Colour coated grades represent the best of Ruukki know-how in
steels and their coatings
- The ready for use surface conceals several new characteristics
carefully tailored to the customers specific requirements
- Coating options are introduced precisely later in this
presentation
20. Coatings
- 100- 225 g/m 2 , when used indoors
- 275 g/m 2when used as a factory coating indoors and
outdoors
- 350 g/m 2to use outdoors without coating or when the coating is
made on site
- The total mass is a combined sum from both sides
- For very demanding conditions it is possible to have 450g/m
zinc coating
21. Coatings zinc coating
- *) g/m means, that there is this amount of zinc, when you
calculate an area that is one square meter-sized
- **) The thickness of the coating ( m) is the average, counted
from three tests. It is a reference value that tells the thickness
on one side. The values in brackets (in above table) are
indicative
22. Coatings zinc coating
- Normal quality MA, allows minor roughness, size alternations in
solidification pattern, dark spots, small gaps, line-like marks and
slight passivation stains
- Horizontal stretcher strains from stretch leveling or zinc
run-off marks are allowed
- If one wishes to paint the zinc coated surface on site, surface
quality MA is recommended
23. Coatings zinc coating
- Demanding quality MB is made by skin pass rolling. This quality
allows only smallsurface imperfections, such as horizontal
stretcher strains from stretch leveling, skin pass marks,
scratches, indentations, spangles, zinc run-off marks, and minor
passivation marks. No holes or gaps are allowed.
- If one wishes to paint the zinc coated surface on site, surface
quality MB can also be used
24. Coatings zinc coating
- Very demanding surface quality MC is made by skin pass rolling.
The better surface quality of this product doesnt affect notably on
the solid appearance of the final painted product
- If you paint coat the zinc coated product in factory, the
surface quality must always be MC
25. Coatings zinc coating
- Unless otherwise agreed, the zinc coated surface is always
protected against white-rusting with chemical passivation (marked
C, product=Cr 3+ )
- If desired, oil protection can also be used(marked O), or both
together (marked CO)
- It is also possible to get the product without protection at
all(marked U)
- Bear in mind that no product, that can be used on site, will
remove the passivation!
26. Steel grades (for coil coating)
27. Steel grades tinsmith quality
- Tinsmith qualities are easy to bend and work with
- Storage doesnt effect on strength. The softness is guaranteed
also for paint coated sheets. The same strength as coated also
- Elongation to fracture: this means the sheets stretchability,
without splitting
- Traditional seaming quality Z02 = DX52D
- This sort of qualities differ from factory made profiles, which
are much harder to bend and work with!

29. Standard zinc coatings
- 275g/m 2 optimal amount of zinc, when organic coatings are
used
- 140g/m 2+ 50g/m 2 A + B side (composite panels)
- 350g/m 2 unpainted outdoor application
- 100g/m 2 indoor application only

46. Maintenance
- Grinding machine is strictly forbidden in every case!
-
- If used, guarantee is immediately no longer valid
-
- Coating burns off and falls away from the cutting point
-
- Hot metal pieces melt into the coating and start to rust
- Also thinner discs damage the coating as well
- Use only tools that doesnt warm up:
-
- Circular saw with hard metal tip and negative angle (cut from
the back side of the sheet)
-
