High-Rise Curtain Wall Solution | CNW Aluminum Extrusion

1. Project Summary: High-Rise Facade Transformation

High-rise commercial construction demands exceptional structural integrity and rapid installation methods. A premier engineering firm based in Jakarta, Indonesia, faced severe engineering limitations with low-grade profiles. By partnering with us, they upgraded their facade systems using our advanced CNW Aluminum Extrusion solutions.

Reading this case study reveals how high-precision curtain wall profiles resolve severe wind resistance bottlenecks. You will discover how modern engineering practices reduce on-site labor and eliminate structural safety risks.

2. The Engineering Challenge in Jakarta

The client, PT. Bangun Cipta Mandiri, specializes in high-rise commercial complexes and office buildings across Jakarta. During recent high-rise developments, their previous suppliers failed to meet critical technical requirements.

• Insufficient Wind Load Resistance: The previous profiles provided a wind load capacity of only 1.2 kPa, falling far short of Jakarta’s strict high-rise baseline of at least 2.0 kPa.

• Inefficient Installation Methods: Traditional silicone-glazed curtain wall systems required complex on-site procedures, causing major schedule delays.

• Severe Surface Degradation: Inferior surface finishes began fading and chalking after just one year of tropical sun exposure.

3. The Custom CNW Engineering Solution

To address these critical facade vulnerabilities, we developed a comprehensive, high-performance facade system. Every custom CNW Aluminum Extrusion was manufactured under rigorous quality control standards to guarantee structural reliability.

• Alloy Grade & Temper: Certified 6063-T6 architectural alloy.

• Profile Wall Thickness: Heavy-duty structure with wall thickness $\ge$ 3.0 mm.

• Structural Capacity: Wind load pressure resistance rated at $\ge$ 2.5 kPa.

• Drainage & Movement: Integrated pressure-equalized internal drainage with 3D adjustable connection nodes.

• Surface Protection: Premium architectural powder coating certified to AAMA 2604 standards.

4. Quantifiable Business Results

Upgrading to our high-strength CNW Aluminum Extrusion delivered outstanding commercial and operational outcomes for the client.

The contractor successfully secured three super high-rise project contracts ranging from 120 to 180 meters in height. These new contracts represented a combined value of approximately $8,000,000 USD. Furthermore, the innovative 3D adjustable joint structure reduced on-site installation labor hours by 35%, allowing the engineering team to hand over projects 15 days ahead of schedule.

During official project inspections conducted two years post-installation, the building facades exhibited zero water leakage and zero coating deterioration.

5. Client Testimonial & Industry Impact

Our advanced structural systems gave the contractor a distinct edge over international competitors during competitive bidding rounds.

"The curtain wall system provided by CNW delivers both remarkable strength and superior assembly efficiency. This solution enabled us to outperform established European competitors during high-stakes bidding."
