[Construction Example 28] Installation of high weather-resistant granite-like exterior material on walls with different substrates.
The method involves painting the base materials of different materials (aluminum, PCa) in a black stone finish at the factory and installing them in new buildings. The result is a high-end appearance.
We would like to introduce an example of the wall surface (aluminum panels and PC panels) of a newly constructed 20-story high-rise building, completed with granite-like "JT-S." 【Property】[New Construction] Umeda Gate Tower (Osaka City, Osaka Prefecture) ◇Construction Date: January 2009 ◇Construction Area: 2,638 m² ◇Substrate: Aluminum panels, PCa panels 【Customer's Challenges and Requests】 ◆ The finishing material for the exterior wall should be a long-lasting paint that maintains its aesthetic appeal over time. ◆ We want to reduce the frequency of renovations and lower maintenance costs. ◆ To shorten the construction period, we would like to install pre-painted finished panels (PCa panels, aluminum panels). 【Adoption Background】 ◇ The design office handling the building requested a black stone-like exterior finishing material. ◇ General paints risk discoloration, and since it is a high-rise building, we proposed our products, which excel in weather resistance and durability, leading to their adoption. 【Selection Points】 ◆ It has strong adhesion that can accommodate different substrates, eliminating concerns about cracks, peeling, or falling off. ◆ It possesses strong adhesion that can be applied to almost all substrate materials, including RC and metal panels. ◆ Since the exterior wall panels can be produced in a factory, on-site work can be omitted, significantly shortening the construction period.
