Astino Uroll Bond Roofing — The Anti-Leak & Rust-Resistant Solution for Housing Projects

Astino Uroll Bond Roofing — The Anti-Leak & Rust-Resistant Solution for Housing Projects

The Astino Uroll Bond is a high-performance metal roofing solution that mimics the elegant profile of traditional clay tiles while providing the unmatched strength of high-tensile steel. Engineered for weather-tightness and corrosion resistance, it is the preferred choice for premium residential and commercial developments across Malaysia.

PRODUCT DESCRIPTION

• For Project Managers and Main Contractors in Malaysia, the primary challenge with traditional roofing is the trade-off between aesthetic appeal and structural longevity. Traditional clay tiles are prone to cracking, heavy weight-loading issues, and persistent leakage at the laps—problems that are exacerbated by Malaysia’s intense tropical downpours and high thermal expansion.
• Large-scale housing schemes and commercial resorts often face “tile fatigue” and water ingress, leading to high maintenance costs and client dissatisfaction. The Astino Uroll Bond is designed specifically to bridge this gap, offering a lightweight yet heavy-duty alternative that eliminates the structural stress of heavy masonry while providing a 100% weather-tight seal.
• By utilizing high-tensile steel substrates coated with advanced corrosion-resistant alloys, the Uroll Bond ensures long-term structural integrity even in high-humidity environments. Its unique interlocking design and anti-capillary groove technology prevent water backflow, ensuring that even under the heaviest monsoon rain, the building envelope remains dry.
• Kee Maju Jaya maintains consistent stock levels to support tight construction timelines. We provide specialized site delivery services to key development hubs, including Kuala Lumpur, Selangor, Penang, Johor, and the East Coast, ensuring your project remains on schedule with factory-direct value.

KEY TECHNICAL FEATURES

• Advanced Anti-Capillary Groove: Specially engineered side-lapping grooves that break surface tension to prevent water siphoning, ensuring 100% leak protection.
• High Strength-to-Weight Ratio: Significant reduction in roof truss load compared to traditional tiles, allowing for cost-savings in structural steel or timber framing.
• Multi-Layer Corrosion Resistance: Features a superior protective coating that prevents oxidation and “white rust,” ideal for the Malaysian climate.
• Thermal Efficiency: Reflective coating technology reduces heat absorption, lowering cooling costs for large-scale industrial or residential buildings.

FAQ SECTION
QUESTION 1: What are the primary structural advantages of using Astino Uroll Bond for large-scale commercial projects?

ANSWER 1: Astino Uroll Bond is significantly lighter than traditional clay or concrete tiles, with weights ranging from 2.88 kg/m² to 5.24 kg/m² depending on thickness. This lightweight profile allows for a more economical roof truss design, reducing the overall structural load and lowering construction costs. When combined with efficient site delivery, it provides a cost-effective, high-performance solution for commercial building envelopes.

QUESTION 2: How does the “Anti-Capillary Groove” technology prevent leaks during heavy Malaysian monsoons?

ANSWER 2: The Uroll Bond is engineered with a 35mm rib height and a specialized anti-capillary groove at the side lap. This design feature prevents water from being drawn upward between the overlapping sheets through capillary action—a frequent cause of leaks in standard metal decking during intense rain. For maximum security, it is recommended to use 4 fasteners at end laps and supports to maintain a weather-tight seal.

FAQ (SOALAN LAZIM)
SOALAN 1: Mengapakah Astino Uroll Bond menjadi pilihan utama untuk projek perumahan premium di Selangor dan kawasan bandar?

JAWAPAN 1: Astino Uroll Bond menggabungkan estetika jubin tradisional dengan prestasi logam yang ringan dan kalis bocor. Dengan kecerunan bumbung minimum hanya 5°, ia menawarkan fleksibiliti reka bentuk yang tinggi untuk seni bina moden. Produk ini mengurangkan beban struktur bangunan sambil memberikan perlindungan unggul terhadap ribut kilat bandar yang kerap berlaku di Lembah Klang.

SOALAN 2: Bagaimanakah bumbung ini menangani masalah karat di kawasan pesisir pantai seperti Terengganu?

JAWAPAN 2: Produk ini dibekalkan dengan salutan pelbagai lapisan (multi-layer coating) yang direka khusus untuk ketahanan kakisan atau teknologi “Tahan Karat”. Spesifikasi teknikalnya yang teguh memastikan material kekal kukuh dari segi struktur dan menarik secara visual walaupun terdedah kepada kelembapan tinggi dan udara masin di kawasan Pantai Timur. Untuk pemasangan optimum, jarak batten bagi sokongan dalaman hendaklah ditetapkan pada maksimum 610mm.
