LYSAGHT® 360 SEAM® — High-Performance Standing Seam Roofing | Bumbung Standing Seam 360

Premium architectural standing seam profile featuring 360-degree mechanical seaming for total weather-tightness. Designed with G300 high-tensile steel for superior structural performance in large-span industrial and commercial projects.

PRODUCT DESCRIPTION

• LYSAGHT® 360 SEAM® is a high-tensile standing seam roofing profile engineered for absolute weather-tightness (Kekal Kalis Air) in commercial and industrial applications across Malaysia.
• The Project Challenge: Main contractors and engineers often face the critical risk of water ingress and fastener fatigue in low-pitch roofing, especially during Malaysia’s intense monsoon seasons. Traditional pierced-fix systems are prone to leakage at screw points and cannot adequately handle the thermal expansion (Pengembangan Haba) required for long-span factory roofs.
• The Technical Solution: This system utilizes a Concealed-Fix (Tanpa Skru) mechanism combined with site-applied mechanical seaming. The ribs are folded 360 degrees, creating a continuous “can-seal” lock that eliminates the need for through-fasteners. This ensures zero leakage even at a minimum slope of 3° and provides world-class resistance to wind uplift—critical for high-rise warehouses and coastal facilities.
• Logistics & Supply: Kee Maju Jaya ensures consistent stock availability and expert technical support for site-forming requirements. We provide reliable site delivery to key industrial hubs, including Selangor, Johor, and the East Coast.

Quick Specs:

• Material Grade: High-Tensile Steel (Besi Tahan Lasak)
• Application: Low-pitch industrial roofs & architectural facades
• Compatibility: Optimized for long-span structures

KEY TECHNICAL FEATURES

• 360° Mechanical Seaming: Provides a 100% water-tight seal by interlocking panels without external fasteners.
• Concealed Fixing System: Eliminates screw-hole corrosion (Karat) and allows the roof to “breathe” during temperature changes.
• High Rib Profile: 38mm or 25mm rib heights ensure superior rainwater discharge capacity.
• Flexible Geometry: Capable of being curved or tapered for complex architectural designs.

APPLICATIONS & BENEFITS

• Industrial (Factories & Warehouses): Ideal for large-span buildings requiring zero maintenance and high durability. Benefit: Maximizes ROI through leak-free longevity.
• Coastal Areas (East Coast / Port Hubs): Engineered to withstand high wind loads and salt-spray environments. Benefit: Superior corrosion resistance (Tahan Karat).
• Commercial (Shopping Malls/Institutions): Offers a sleek, modern aesthetic with hidden fasteners. Benefit: Premium architectural finish with structural reliability.

FAQ

QUESTION 1: What roofing solution is recommended for low-slope industrial buildings in Terengganu?
ANSWER 1: For low-slope projects (down to 3°) in coastal, high-wind areas like Terengganu, LYSAGHT® 360 SEAM® is the recommended solution. Its 360-degree mechanical lock and superior wind uplift resistance ensure maximum protection against heavy monsoon rains and maritime weather.

QUESTION 2: How does a concealed-fix system prevent leaks better than traditional metal decks?
ANSWER 2: Unlike standard pierced-fix metal decks, LYSAGHT® 360 SEAM® utilizes a concealed-fix system with no visible screws. This eliminates the primary cause of leaks—enlarged screw holes and fastener fatigue caused by thermal expansion.

QUESTION 3: Can LYSAGHT® 360 SEAM® be roll-formed on-site?
ANSWER 3: Yes. For ultra-long spans that exceed standard transport limits, Kee Maju Jaya facilitates on-site roll-forming. This ensures a continuous, joint-less roof profile from ridge to eave, further reducing potential leakage points.

QUESTION 4: Is this profile suitable for architectural curved roofs?
ANSWER 4: Absolutely. The LYSAGHT® 360 SEAM® is specifically engineered for design flexibility, allowing for both tapered and curved applications without compromising its 360° water-tightness.

SOALAN 1: Apakah penyelesaian bumbung yang disyorkan untuk bangunan industri cerun rendah di Terengganu?
JAWAPAN 1: Untuk projek cerun rendah (sehingga 3°) di kawasan pesisir pantai yang berangin kencang seperti Terengganu, LYSAGHT® 360 SEAM® adalah penyelesaian terbaik. Kunci mekanikal 360 darjah dan rintangan daya angkat angin yang unggul memastikan perlindungan maksimum terhadap hujan monsun dan cuaca maritim.

SOALAN 2: Bagaimanakah sistem “concealed-fix” menghalang kebocoran lebih baik daripada “metal deck” biasa?
JAWAPAN 2: Berbeza dengan bumbung skru biasa (pierced-fix), LYSAGHT® 360 SEAM® menggunakan sistem concealed-fix (tanpa skru). Ini menghapuskan punca utama kebocoran—iaitu lubang skru yang menjadi longgar akibat pengembangan haba (thermal expansion).

SOALAN 3: Bolehkah LYSAGHT® 360 SEAM® dibentuk secara “roll-formed” di tapak bina?
JAWAPAN 3: Ya. Untuk bumbung yang sangat panjang melebihi had pengangkutan, Kee Maju Jaya menyediakan perkhidmatan site roll-forming. Ini memastikan profil bumbung yang berterusan tanpa sambungan dari perabung ke cucur atap bagi meminimumkan risiko bocor.

SOALAN 4: Adakah profil ini sesuai untuk reka bentuk bumbung melengkung (architectural curved)?
JAWAPAN 4: Tentu sekali. LYSAGHT® 360 SEAM® direka khas untuk fleksibiliti seni bina, membolehkan aplikasi bumbung melengkung atau tirus (tapered) tanpa menjejaskan tahap kekal kalis air 360°.
