Features
- One of the most advance and versatile metal roofing profile available today
- Widely used for sophisticated roofing and cladding design for large scale or mega projects
- High-ribbed profile of 65mm results in excellent drainage of rain water and a low pitch roof design of 1.5 degree

Tapered & Curved Design
- Utilizing tapered and curved profile forming, application ranges from dome design to wave-like structure
- Materials ranging from zinc coated steel to aluminum sheets provide flexibility in terms of design and budget

Coating Specifications

Solar Reflectivity (SR)
Solar reflectivity or reflectance is the ability of a material to reflect solar energy from its surface back into the atmosphere. The SR is value is a number from 0 to 1.0 A Value of 0 indicates that the materials absorbs al solar energy and a value of 1.0 indicates total reflectance. Energy Star requires and initial SR value of 0.25 or higher for steep slope (>2:12) roofs and 0.15 or greater after three years. Low slope roofs require an initial SR value of 0.65 or higher and 0.50 or greater after three year.
Solar Reflectance Index (SRI)
The Solar Reflectance Index is used for compliance with LEED requirements and is calculated according to ASTM E 1980 using values for reflectance and emissivity. Emissivity is a material’s ability to release absorbed energy. To meet LEED requirements a roofing material must have a SRI of 29 or higher for steep slope (>2:12) roofing and a SRI value of 78 or higher for low slope roofing.
