What is the meaning of the name "LYSAGHT CUSTOM ORB®" and "LYSAGHT CUSTOM BLUE ORB®"?
"LYSAGHT CUSTOM ORB®" is the name given to the "corrugated iron" cladding shape made by BlueScope Lysaght. The name came from the customs stamp on the corrugated iron when it was first imported from England about 150 years ago. The stamp was of the royal "orb" (ball shape on top of the royal staff). The colour reference relates to the type of steel used many years ago. The "blue" was referred to as the soft steel and the "red" referred to the hard or strong steel. The "red" in the name has been dropped over the years.
What is the difference between LYSAGHT CUSTOM ORB® and LYSAGHT CUSTOM BLUE ORB®?
LYSAGHT CUSTOM ORB® is a thinner material, but of high strength steel suitable for roofs and walls. The LYSAGHT CUSTOM BLUE ORB® is a thicker material but of softer strength steel, suitable for pre-curving for use in verandahs and tanks, but also roofs and walls.
When considering LYSAGHT CUSTOM ORB® and LYSAGHT CUSTOM BLUE ORB®, which cladding should I use?
Each product has benefits and uses in particular situations. As a cladding LYSAGHT CUSTOM ORB® in a 0.48mm BMT has about the same strength as LYSAGHT CUSTOM BLUE ORB® in 0.60mm. Therefore, if you don't need to curve the material and it is required for cladding, the thinner steel would be more economical.
What is cladding and how does it relate to roofing and walling?
Cladding is a collective term for any sheeting that covers a building, whether it be on the roof of the building, or on the walls. Roof cladding is made from thicker steel and is rolled to a profile capable of supporting roof traffic*. In most cases, these roof claddings can also be used for walling as well. Wall cladding is made from thinner steel, rolled to a less rigid profile. They are generally not capable of supporting roof traffic, prohibiting their use as roofing.
*Some roofing is designed to be non-trafficable. Please consult the span and capacity tables of the cladding for further details.
