Astino BONDECK 680 Structural Steel Decking — High-Tensile Composite Solution | Lantai Bondek Astino

Astino BONDECK 680 Structural Steel Decking — High-Tensile Composite Solution | Lantai Bondek Astino

The Astino BONDECK 680 is a high-performance structural steel decking system engineered for composite concrete slabs. Designed to act as both a permanent formwork and positive reinforcement, it significantly reduces construction time and material costs for multi-story industrial and commercial developments.

 

PRODUCT DESCRIPTION

• In large-scale Malaysian construction, Project Managers and Structural Engineers often face the triple threat of rising labor costs, tight deadlines, and the logistical nightmare of traditional timber formwork. For high-rise commercial hubs and industrial warehouses, the need for a solution that ensures structural integrity while speeding up the floor casting process is critical. Astino BONDECK 680 is specifically designed for heavy industrial and commercial projects where load-bearing efficiency is paramount.
• Conventional slab pouring requires extensive propping and eventual stripping of formwork, which introduces delays and safety risks. This structural decking solves the problem by providing immediate, high-tensile reinforcement that bonds with the concrete. The precision-engineered ribs provide a mechanical interlock that prevents lateral slip, ensuring the composite slab performs as a single, rigid unit under heavy live loads.
• Kee Maju Jaya maintains a consistent inventory of Astino BONDECK 680 to support rapid project cycles. With our optimized logistics network, we provide reliable site delivery to key hubs including Kuala Lumpur, Selangor, Penang, Johor, and the East Coast, ensuring your project timeline remains uninterrupted by supply chain gaps.

KEY TECHNICAL FEATURES

• Composite Interlocking Profile: The unique rib design ensures a superior mechanical bond with the concrete, allowing the decking to act as permanent positive reinforcement.
• High-Tensile Durability: Manufactured from premium high-tensile steel to provide maximum structural rigidity while minimizing the need for additional reinforcement bars.
• Permanent Formwork System: Functions as a safe working platform during construction and stays in place after pouring, eliminating the time and labor cost of stripping timber forms.
• Enhanced Corrosion Resistance: Coated with a high-grade protective finish to withstand the high humidity and tropical conditions typical of Malaysian construction sites.

 

APPLICATIONS & BENEFITS

• Industrial (Factories & Warehouses): Used in heavy-duty mezzanine floors and storage levels. Benefit: High load-bearing capacity and compliance with industrial safety requirements.
• Commercial (High-Rise Offices & Malls): Ideal for rapid floor construction in urban centers like KL and JB. Benefit: Reduces overall building weight and accelerates the construction cycle for faster ROI.
• Infrastructure (Power Plants & Utility Buildings): Employed in structures requiring long-term durability. Benefit: Certified quality ensures the structure remains resilient against vibration and environmental stress.
• Coastal Developments: Suitable for projects in the East Coast or Penang. Benefit: Superior coating technology provides essential “Tahan Karat” (rust resistance) properties in salt-mist environments.

FAQ SECTION

Question 1: What is the advantage of using Astino BONDECK 680 over traditional plywood formwork?

Answer 1: Astino BONDECK 680 serves a dual purpose as both permanent formwork and structural reinforcement. Unlike plywood, it remains in place after the concrete cures, which drastically reduces labor costs, eliminates site waste, and provides a cleaner, professional finish to the slab soffit.

Question 2: Can Astino BONDECK 680 be used for projects in high-humidity coastal areas like Kuantan or Terengganu?

Answer 2: Yes. Our BONDECK 680 is supplied with a high-grade protective coating specifically engineered for “Tahan Karat” (rust resistance) performance. This makes it the ideal choice for the Malaysian climate, ensuring the structural integrity of the slab remains uncompromised by tropical corrosion or salt-mist environments.

Question 3: Does Kee Maju Jaya provide site delivery for large-scale construction projects in Johor and Penang?

Answer 3: Kee Maju Jaya specializes in B2B logistics, offering direct-to-site delivery to major project hubs across Peninsular Malaysia, including Johor, Penang, and the Klang Valley. We prioritize schedule synchronization to ensure our delivery aligns perfectly with your concrete pouring timeline.

Question 4: How does this decking contribute to the overall fire safety of a building?

Answer 4: When integrated into a composite concrete slab, the Astino BONDECK 680 system is designed to meet stringent industry safety standards. The synergy between the steel decking and concrete mass provides excellent fire resistance, making it a preferred choice for high-occupancy commercial and industrial buildings.

 

Soalan 1: Apakah kelebihan menggunakan Astino BONDECK 680 berbanding acuan papan lapis (plywood) tradisional?

Jawapan 1: Astino BONDECK 680 berfungsi sebagai acuan kekal dan juga tetulang struktur. Tidak seperti papan lapis, ia tidak perlu dibuka selepas konkrit mengeras. Ini mengurangkan kos buruh dengan ketara, menghapuskan sisa binaan di tapak projek, serta memberikan kemasan yang lebih kemas dan profesional pada bahagian bawah papak lantai.

Soalan 2: Bolehkah Astino BONDECK 680 digunakan untuk projek di kawasan pesisir pantai yang berkelembapan tinggi seperti Kuantan atau Terengganu?

Jawapan 2: Ya. BONDECK 680 kami dibekalkan dengan salutan pelindung gred tinggi yang direka khusus untuk prestasi “Tahan Karat”. Ini menjadikannya pilihan ideal untuk iklim Malaysia, memastikan integriti struktur papak lantai tidak terjejas oleh kakisan tropika atau persekitaran semburan garam laut.

Soalan 3: Adakah Kee Maju Jaya menyediakan penghantaran ke tapak bina untuk projek pembinaan berskala besar di Johor dan Pulau Pinang?

Jawapan 3: Kee Maju Jaya pakar dalam logistik B2B, menawarkan penghantaran terus ke tapak projek di seluruh Semenanjung Malaysia, termasuk Johor, Pulau Pinang, dan Lembah Klang. Kami mengutamakan penyelarasan jadual bagi memastikan penghantaran kami selaras dengan waktu kerja konkrit (pouring) anda.

Soalan 4: Bagaimanakah sistem “decking” ini menyumbang kepada keselamatan kebakaran sesebuah bangunan?

Jawapan 4: Apabila digabungkan ke dalam papak konkrit komposit, sistem Astino BONDECK 680 direka untuk memenuhi piawaian keselamatan industri yang ketat. Gabungan antara kepingan besi decking dan jisim konkrit memberikan rintangan api yang cemerlang, menjadikannya pilihan utama bagi bangunan komersial dan industri dengan kepadatan tinggi.
