Astino Spandec Metal Roofing — High-Tensile Structural Decking | Atap Zink Spandec Astino

Astino Spandec Metal Roofing — High-Tensile Structural Decking | Atap Zink Spandec Astino

 

Astino Spandec is a premium high-strength metal roofing profile designed for superior water shedding and structural integrity. Engineered with a deep ribbed profile, it offers exceptional spanning capabilities and long-term weather resistance for commercial and industrial developments.

 

PRODUCT DESCRIPTION

• Roofing failure in large-scale industrial projects often stems from two critical issues: structural deflection under heavy rain and rapid corrosion due to Malaysia’s high humidity. For Project Managers and Main Contractors, selecting a profile that balances load-bearing capacity with leak prevention is vital to avoiding costly rectifications and maintaining the building’s lifespan.
• The Project Challenge Conventional roofing profiles often struggle with water ponding and capillary action, especially on low-pitch roofs common in warehouses and factories. This leads to premature rust and internal ceiling damage. Astino Spandec is specifically engineered for heavy industrial and commercial projects where long-span reliability and high-volume water discharge are non-negotiable requirements.
• The Technical Solution Utilizing high-tensile steel, the Spandec profile features a bold, trapezoidal rib design that significantly increases the Moment of Inertia. This allows for wider purlin spacing without sacrificing stability. The advanced anti-capillary side-lap ensures a weather-tight seal, effectively neutralizing the risk of backflow during monsoon-level downpours.
• Logistics & Availability Kee Maju Jaya maintains a consistent inventory of Astino Spandec to meet demanding project timelines. We specialize in coordinated site delivery to key industrial hubs across KL, Selangor, Penang, Johor, and the East Coast, ensuring your materials arrive ready for immediate installation.

 

KEY TECHNICAL FEATURES

• High-Tensile Strength: Manufactured from premium grade steel to ensure maximum rigidity and resistance against impact or foot traffic during maintenance.
• Superior Spanning Capacity: The deep-ribbed profile allows for increased distances between supports, reducing overall structural steel costs.
• Anti-Capillary Groove: Specially designed side-lap features prevent water from being drawn into the laps via capillary action, ensuring a leak-proof finish.
• Corrosion Resistant Coating: Treated with advanced protective layers to withstand Malaysia’s harsh UV rays and high moisture levels.

 

APPLICATIONS & BENEFITS

• Industrial (Factories & Warehouses): Used for large-scale roof covers and wall cladding. Benefit: High-volume water shedding and structural durability for heavy-duty protection.
• Commercial (Shopping Malls & Hubs): Ideal for modern architectural designs requiring clean lines. Benefit: Aesthetic versatility combined with industry-standard compliance.
• Coastal Areas (East Coast/Penang): Enhanced coating protection for buildings near the sea. Benefit: Superior corrosion resistance (Tahan Karat) against salt-mist environments.
• Infrastructure Projects: Suitable for TNB substations or government facilities. Benefit: Reliability and long-term maintenance cost savings.
