COLORBOND® steel is one of the worlds most advanced

pre-painted steel products for the building and construction

industry.

COLORBOND® steel offers architects, designers, builders

and owners a versatile, lightweight, strong and aesthetically

pleasing solution for almost any type of building and environ-

ment.

COLORBOND® steel is really three products in one system. It

has been designed to provide the excellent Strength of the

steel base, the Corrosion Resistance of zinc-aluminium

alloy coated ZINCALUME® steel and the superior Aesthetics

of an advanced paint system.

Other products may look the same, but they don't always

match the performance of COLORBOND® steel.

Cross Sectional View of COLORBOND® steel

A product of intensive research and design, COLORBOND®

steel was introduced in 1966, and even today continues to be

the benchmark for the industry.

The painted surface is not just paint; it is a paint system - the

agglomeration of a four-stage process that delivers long life,

superior anti-corrosion performance - and above all superior

aesthetics.

The four stages begin with a ZINCALUME® steel base which

has a chemically applied conversion coating. An epoxy primer

is then baked onto the surface, after which the topcoat is

baked on.

Product RangeCOLORBOND® steel coils conform to AS/NZS 2728 and are

typically supplied in 12 standard colours with base metal

thickness ranging between 0.40 mm to 0.80 mm and strip

width between 940 mm and 1220 mm. Special requirements

in different parameters can be offered. Protective film is

available as an optional extra.

COLORBOND® steel is manufactured using high quality

steel. In general two grades of steel are used for roof and wall

cladding applications, which are G550 and G300.

G550 steel grade is also referred as 'High Strength Steel',

where the minimum Yield Strength of steel is 550 MPa, while

G300 steel grade is referred as 'Soft Steel' where the

minimum Yield Strength of steel is 300 MPa.

In general high strength steel (G550) is preferred for roof and

wall cladding applications because of its inherent properties

and benefits over soft steel. G300 is used where high

formability is required.

Superior Paint TechnologyAround the globe COLORBOND® steel has gained a

reputation as the best colour coated corrosion resistance

product, specifically for roof and wall cladding applications. It

adds life to your building with long lasting aesthetics.

The proprietary paint system of COLORBOND® steel gives it

long life, superior aesthetics and excellent corrosion

resistance.

The unique combination of resins and inorganic pigments

used in COLORBOND® steel provides it with the ability to

resist colour change longer than most pre-painted

alternatives in most environments.

COLORBOND® steel is tested for all criteria required for

colour coated steel products to perform in the external

environment and is designed to be successful under

ultra-violet exposure, high temperature, humidity and salty

atmosphere.

Resistance to Colour ChangeThe fading colour of pre-painted steel is typically caused by

exposure to UV radiation in sunlight and other external fac-

tors that are beyond our control.

The unique composition of the paint system consists of

stable resins and inorganic materials. Stable resins unlike

regular resins do not break down as a result of UV radiation,

thus preventing fading, chalking, while inorganic materials

e.g. iron oxide are renowned for their stability when exposed

to UV radiation.

The paint system provides COLORBOND® steel with the

capability to withstand fading of colours for a longer period of

time as compared to most pre-painted alternatives.

The unique quality of COLORBOND® steel is reinforced by its

ability to weather evenly to provide consistent colour across

the exposed surface. As a result of superior colour

performance, COLORBOND® steel is unsurpassed by any

other pre-painted steel available in the market.

Superior Paint AdhesionThe coating used for manufacturing COLORBOND® steel has

been formulated to resist cracking and peeling during forming

and pressing at the roll form machine.

The high degree of ductility does not lead to a softening in

the paint film hardness. Even after roll forming,

COLORBOND® steel resists peeling and flaking for much

longer in comparison to any other product of the same

category.

It can withstand conditions of high speed wind, hail, falling

branches and flying debris. Its top finish superbly resists

chipping, cracking and peeling.

Water absorption through the paint film may result in blister-

ing and delamination. The special binder in COLORBOND®

steel provides resistance to this phenomenon, thereby

ensuring that the paint film is intact for long.

Design FlexibilityCOLORBOND® steel is lightweight and strong, it provides

maximum flexibility and its extensive range of colours and

profiles ensure truly individual solutions.

It's also easy to erect, and gives long life and low mainte-

nance. Its easy formability and bending property opens new

horizons to the thoughts of architects.

Leading architects attest COLORBOND® steel for its virtually

limitless design possibilities. They use it for everything from

award-winning modern homes to modern industrial sheds or

innovative interior designing.

It is no surprise that COLORBOND® steel continues to be the

preferred option for numerous landmark projects in the

building and construction industry.

Thermal EfficiencyWhatever be the climate, COLORBOND® steel is the smart

and energy-efficient choice. A roof and wall made from

COLORBOND® steel can result in less heat radiated into the

building compared to other commonly used materials.

The reflectivity and low thermal mass of COLORBOND®

steel, combined with insulation, makes it a cost effective and

energy efficient roofing solution.

Environment FriendlyBuildings using COLORBOND® steel can be installed in a

shorter period of time. Unlike conventional building practices,

there is no mixing or wastage at site.

Hence, there is no strain on the local flora and the buildings

blend easily with the environment.

COLORBOND® steel contains no lead, making it a suitable

option for water harvesting.

Another advantage is that COLORBOND® steel is recyclable.

DurabilityZINCALUME® steel is chosen mainly as the substrate for

COLORBOND® steel, for most roofing and wall cladding

applications, because of its superior ability to resist corrosion

upto four times longer than galvanised steel of equivalent

coating thickness.

By combining the strength of its steel substrate, with the

corrosion resistance of superior coating, COLORBOND®

steel ensures the aesthetic beauty of the finished product will

last for many years to come.

In South Asia, the environmental and weather conditions vary

from one extreme to the other. COLORBOND® steel has

proved to be an ideal solution for tropical climates, capable of

withstanding extreme environmental conditions, and giving

long lasting aesthetical looks to buildings.

At the same time, it also provides a safe, secure and durable

barrier against pests and intruders.

Tested for Assured Performance

COLORBOND® steel undergoes numerous tests for

evaluating its performance in different environments.

COLORBOND® steel is subjected to not only

laboratory test but is also tested in the external environment

to evaluate its corrosion resistance and durability as

compared to other pre-painted steel.

Panels of COLORBOND® steel and competitive products

were placed at a test site in severe marine conditions at

Bellambi Point, Australia. After 9 years of continuous

exposure, COLORBOND® steel shows minimal corrosion

while apparent visual corrosion effects could be seen on

the other pre-painted steel.

COLORBOND® steel has emerged as superior in corrosion

resistance again and again, so why use any pre-painted

steel, when you can have the best and technically proven

product for your roof and wall cladding applications.

Easy to Maintain

COLORBOND® steel should be handled carefully to avoid

damage to the surface.

The process of taking care starts from the packaging to

transportation to storage to processing to again packing and

delivering to the site. It is also essential to adopt proper

installation practices.

Regular washing with water on areas that are not exposed to

rain will enhance the expected life and the attractiveness of

the painted finish for a longer period of time.

Touch up paints should be avoided as it creates patches of

uneven colouring. If a sheet is badly scratched, it should be

replaced immediately.

Any debris (e.g. swarf, surplus fasteners) should be carefully

removed at the completion of work each day, to minimise risk

of localised corrosion.

Applications and End-Usages

COLORBOND® steel is the preferred option for construction,

especially where aesthetics is valued equally with long-life.

Roofing

From classic corrugated sheeting through contemporary

profiles to architectural panels, COLORBOND® steel is the

natural choice for roofing applications.

Being light weight, it reduces the amount of framing required.

Longer spans enable economic truss design.

Wall Cladding

COLORBOND® steel is an attractive, durable and economical

wall cladding solution for any environment.

In addition to the practical benefits and aesthetic appearance,

it also acts as an impenetrable barrier to intruders and pests.

Gutter, Flashing and Accessories

To ensure equal durability for gutter, flashing and acces-

sories, it is recommended that these are manufactured out of

the same product system used for main roofing and wall

cladding.

CompatibilitySome precautions as mentioned below should be followed to

get the best from COLORBOND® steel:-

• Don't allow contact with incompatible materials, which

include lead, copper, monel, bare steel, stainless steel

(except COLORBOND® Stainless steel), green or

chemically-treated timber (like CCA or tanalith treatments),

wet or dry concrete, soils, vegetable matter, any material

which will inhibit normal exposure to the atmosphere

• Don't allow discharge of rainwater from incompatible

materials onto COLORBOND® steel products

• Ensure that supporting members and fasteners are

compatible and have similar life expectancy

• Do not mix COLORBOND® steel with 'same colour' pre-
