What is Pre-painted Steel?

12

Pre-painted roof sheet steel is generally composed of a

steel substrate protected by a corrosion resistant metallic

coating, a surface treatment, a primer and a topcoat.

Differences between Chromadek® and

Chromadek Ultim®


Quick facts on the paint system

14

• The steel substrate is hot-dip galvanized.

• The zinc layer gives a first protection against corrosion in Z200 for Chromadek® and >Z275 for Chromadek Ultim®.

…the substrate?

• The surface treatment is the first step in coil coating.

• This is a very thin layer of a few nanometers to ensure the adhesion of the organic layer to the substrate enhancing the corrosion resistance.

…the surface treatment?

• The role of the primer is to promote adhesion ensuring the corrosion resistance of the top or bottom coat application, usually applied from 5μm.

…the primer?

15

More facts on the paint system

• The topcoat provides the required surface characteristics, such as final appearance (colour, gloss & texture), hardness, resistance to ultraviolet and resistance to abrasion.

…the topcoat?

• Similar to the top coat with less harsh exposure and most importantly to guard against opportunistic corrosion derived from moisture and condensation (in certain instances the back coat is unwashed and this presents an opportunistic area for failure), this is where Chromadek Ultim® is superior.

Improved paint systems for Chromadek®

The aesthetic life of the paint system is governed by the

stability of the paint system against degradation from

sunlight (UV, temperature) which is revealed by the degree

Heat reflective roofing solutions

An exciting development in Heat Reflective roofing solutions

Four of the colours of the Chromadek® range (See Data Sheet C1.4),

Charcoal Grey, Dark Dolphin, Buffalo Brown and Aloe Green utilize an

advanced thermal technology paint system. This advanced paint system

incorporates a heat reflective pigment providing up to 8°C cooling and

improved durability. The durability of an exterior coating is measured

according to its capability of maintaining gloss, colour and film integrity.

How Heat Reflective Chromadek® works?

The heat reflective pigments present in Heat Reflective Chromadek® are

chemically inert and highly stable. Heat Reflective Chromadek® reflects

more of the sun’s energy to prevent the coating from absorbing energy

directly resulting in less heat build up resulting in longer life-cycles (less

fading).

It’s really cool!

• If it doesn't say Chromadek®, it won’t last like Chromadek

®.

• Not all colour roof sheeting is Chromadek®.

• Chromadek®, is marked on the reverse side at intervals of approximately.

900mm, parallel to the length of the strip, about 25mm from the edge.

• The letters are approximately 5mm in height and of the dot-matrix type.

Gentle care for Chromadek®

30

• Walking on roofs (avoid abrasive contact, soft contact)

• Scheduled roof maintenance (regular and important)

• Roof location (avoid adverse conditions)

• Roof pitch (< 5 degrees is a flat roof)

• Different metal compatibility

Correct type and class of fastener

Special fixtures for fitting solar panels

• Cutting:

- Avoid Swarf and Sparks from angle grinders

- Suggested alternatives, circular saw and nibbler cutting

• Storage and handling:

- Guidelines on the correct storage and handling practice

Key considerations for Chromadek®

Considerations when caring for

Chromadek®

31

• Damage to paint coating • Repainting of roofs

3 interacting aspects

cause

effect

guidelines

Do’s and dont’s for Chromadek®

• Metal deposits: Loose fasteners, pop-rivet mandrills, metal

drillings/objects increase the risk of corrosion and should be

removed.

• Damage to paint coating could increase the risk for corrosion if

considered to be severe. Cleaning and touching-up with

appropriate paint should be considered. In areas where edge

corrosion is evident - (i.e. overlapping sheets and sheet ends),

the corrosion will spread unless treated in good time. Clean the

corroded edge thoroughly and repaint.

• Repainting of roofs:

If the need should arise to repaint a Chromadek® roof, it can be

done with an appropriate roof preparation method and a suitable

paint system. ArcelorMittal can be contacted for advice and

referral to approved and reputable roofing refinisher(s).

32

3 aspects to keep in mind

33

Handy Hints for Chromadek®

• If Chromadek® sheeting has been scratched to the substrate, it should be repaired with approved touch-

up paint with a thin paint brush to minimise unnecessary over-painting. Light scratches are best left

untreated. (Contact AMSA fore more info or visit our datasheet, C1.4)

• Wash the underneath of eaves down with fresh water every six months.

• Abrasive cutting or trimming of Chromadek® sheeting on top of roofs should be avoided. However, if

unavoidable, the iron particles must be removed from the roof surface by means of a non-scratch bristle

brush or broom, as it is not easily washed down by rain. If left on the roof the iron particles will start to

rust, tarnishing the Chromadek® paint surface. See Slide for recommended cutting equipment.

Rusted iron

particles

Prevention is recommended, apply correct cutting & cleaning practices

34

Recommended cutting practice

To minimize & avoid swarf. (see video)

ArcelorMittal Makita.mov

Alternative to angle grinder cutting




35

• The slope of the roof shall be such that water can drain freely from it without

forming ponds. The minimum recommended slope for Box Ribbed or S-Rib

sheeting is 5°.


Prevention is recommended, apply correct roof design


36

Prevention is recommended, apply correct storage practices

Fasteners to be used

• Ensure that the correct class of fasteners are used for the

application. All fasteners used for fixing Chromadek® to be in

accordance with AS 3566 Class 3 (correct class of fastener to be

applied for marine and industrial applications).

• Make sure fasteners are also washed and inspected for signs of

corrosion. Replace if they show signs of failure, rust or

degradation of the waterproof membrane.

• For coastal or heavy marine you need to use Class 4 fasteners

(Chromadek Ultim® applications)

• Chromadek® warranty advises the above.

37

Incorrect fasteners are the preferential site for premature metal roof

failure

Ordinarily Class 3 for Chromadek® & Class 4 for Chromadek Ultim®

Claims handling

• Claims are investigated on a case by case basis.

• Below is an example for inspection of colour changes
