Product Introduction

Colorbond steel is a trademark brand of BlueScope steel Australia. It is manufactured using high quality steel with minimum yield strength of 550 Mpa, that makes it superior to similar alternatives available in the market. In Maldives, Colorbond steel is the most preferred choice for good quality roofing and cladding.

Colobond steel has been specifically designed and developed for high durability as well as for better installation and can be used for roofing and wall cladding applications and are widely accepted in Maldives.

Comparison with normal color coated steel

The superior paint system of Colorbond steel gives it long life, aesthetics and excellent corrosion resistance. Fig. 2.1 and 2.2 are examples from Maldives.

From the figure 2.1 we can see that the top roof of the building is installed with Colorbond steel but the bottom roof is installed with low-standard ordinary roof. We can clearly see the extent of the color fading from the bottom roof in comparison with the top Colorbond roof.

The reason is due to Colorbond’s tested stable resin and inorganic pigments that do not break down as a result of UV radiation, thus resisting fading, chalking and giving a remarkable color stability when exposed to such conditions.

Figure 2.2 shows a typical low cost roof installed just adjacent to the Colorbond roof (right). It can be clearly seen the extent of color fading as well as cutedge corrosion.

However Colobond roof’s cut-edge remain smooth and free from any stain or corrosion due to its remarkable Cut-Edge Protection system.

High Yield Strength

The high yield strength of Colorbond G550 (High-Strength Steel) makes it suitable for various applications requiring durability and long service life.

When compared to low standard roofing sheets, Colorbond sheets have greater resistance to dents and damages.

As shown in figure 2.3, wider spans with lesser thickness are possible due to the high concentration of Aluminum (55%) which makes 80% of the coating volume in the Colorbond material.

Steel and Coating Properties

As shown in the below figure 2.4 and 2.5, the paint system of Colorbond steel uses stable inorganic pigments and especially developed resins for better paint performance. Moreover, absence of lead in the paint system makes it 100% suitable for water harvesting as well.
