LYSAGHT® SPANDEK® OPTIMA™
PENUTUP ATAP DINDING YANG KUAT DENGAN ESTETIKA
LYSAGHT SPANDEK® dirancang sebagai bahan penutup atap dan dinding yang kuat, estetik, dan efisien dengan bentuk gelombangnya yang kontemporer untuk bangunan perumahan, industri, dan komersial. LYSAGHT SPANDEK® juga telah dikenal di Indonesia, Australia, dan negara-negara lain sebagai bahan penutup atap perumahan dan bangunan sosial karena kemudahan dalam penggunaan dan penampilannya yang menarik.
MENGAPA LYSAGHT SPANDEK®
– LYSAGHT SPANDEK® dibuat dari baja bertegangan tarik tinggi ZINCALUME® dan Clean COLORBOND® dari BlueScope Steel. Baja ZINCALUME® adalah baja dengan lapisan yang terdiri dari perpaduan antara 43.5% Seng, 55% Alumunium dan 1.5% Silikon sebagai lapis pelindung terhadap korosi yang tinggi. Ketahanan ZINCALUME terhadap korosi empat sampai lima kali dibanding baja galbani lain – Clean COLORBOND® adalah baja berwarna dengan bahan dasar ZINCALUME®. Penggunaan sistem pengecatan dan lapisan primer yang bermutu tinggi pada ZINCALUME® meningkatkan ketahanan terhadap korosi dan menjamin mutu cat – Multi fungsi untuk aplikasi atap maupun dinding
LYSAGHT® SPANDEK® OPTIMA™ steel roofing profile is a symmetrical trapezoidal ribbed roofing and wall cladding profile. It is ideal for designs where a stronger, bolder and modern corrugated appearance is required.
It can be used in buildings that require long spans as it permits wider purlin spacings* and utilizes fewer fasteners. Its rigid trapezoidal rib makes it an excellent choice for for contemporary roof and wall cladding designs.
The cost-effective LYSAGHT® SPANDEK® OPTIMA™ steel roofing profile is multi-faceted and can be used in a variety of ways for both roof and wall in single and double span applications.
The trapezoidal ribs can be installed horizontally or vertically. The continuous running angular outline makes the ribbed and stylized trapezoidal LYSAGHT® SPANDEK® OPTIMA™ profile more appealing. The contrasting effect of light and shadow arising under light creates a distinctive and natural dimensional wave.

Warranty
BlueScope Steel offers a warranty (subject to environmental conditions) for Clean COLORBOND® steel and ZINCALUME® steel of up to 20 years from the date of installation against perforation by weathering in the natural elements.
Warnings
Lead and copper are not recommended for use with Clean COLORBOND® steel or ZINCALUME® steel as contact with these metals can cause accelerated corrosion. The minimum recommended roof pitch is 1 degree. Direct contact should therefore be avoided. When inside condensation conditions are likely, coated steel girts should be used so that ZINCALUME® steel coming into contact with bare steel is avoided.
* Total Coated Thickness (TCT) for Clean COLORBOND® ULTRA steel is 0.48mm (Standard) and 0.54mm (Non-Standard).
**Span is subject to designed live loads and verifications. Maximum Roof Run (in metres) for Roof Slopes and Rainfall Intensities
Minimum Ridge Purlin Spacing for Sprung Ridge LYSAGHT® SPANDEK® OPTIMA™ Profile
Recommended Radius for LYSAGHT® SPANDEK® OPTIMA™ curved applications
For a curve radius greater than the recommended minimum, the purlin spacing must not exceed 2,400mm for LYSAGHT® SPANDEK® OPTIMA™ Profile 0.42mm BMT and 3,000mm for LYSAGHT® SPANDEK® OPTIMA™ Profile 0.48mm BMT.
* Maximum recommended radius to provide sufficient drainage near crest of curvature.
Limit States Wind Pressures
The wind pressure capacities are based on tests conducted at BlueScope Lysaght’s NATA registered testing laboratory. Testing was conducted in accordance with AS 1562.1 – 1992 Design and Installation of Sheet Roof and Wall Cladding – Metal, and AS 4040.2 – 1992 Resistance to Wind Pressure for Non-cyclonic Regions.
The pressure capacities for serviceability are based on a deflection limit of (span/120) + (maximum fastener pitch/30). The pressure capacities for strength have been determined by testing the cladding to failure (ultimate capacity). These pressures are applicable when the cladding is fixed to a minimum of 1.0mm, G550 steel.
For material less than 1.0mm thick, please contact our technical sales representatives for assistance.
