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

Coating options

Zinc coating

• 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

Zinc coating

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)

Structural steels

• S280GD + Z

• S320GD + Z

• S350GD + Z

Formable steels

• DX51D + Z

• DX52D + Z

• DX53D + Z

• DX54

• S220 and S250

27. Steel grades tinsmith quality

Tinsmith qualities are easy to bend and work with

Doesnt age

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!

Elongation min . DX51D DX52D DX53D DX54D 300 260 220 (340) 22 26 30 36 This feels in hands as hardness or softness Traditional seaming quality N/mm % 28. Steel grades applications

45. Maintenance

You need to paint carefully to the scratch! Use Ruukkis repairing paints

Painting with aerosol products is prohibited:

• Resistance to corrosion is weak

• Resistance to UV radiation is weak

• Colour changes quickly

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)

• Handsaw with metal blade

• Nibbler (can be used from both sides)
