Flat Roof Solar Mounting System (Ballasted Type)
The Flat Roof Solar Mounting System is a cost-effective and highly reliable solution designed for installing photovoltaic systems on flat concrete roofs and ground-level flat surfaces. Using a ballasted installation method, the system eliminates the need for roof penetration, helping protect roof integrity while ensuring stable structural performance.
This system is widely used in commercial buildings, industrial facilities, warehouses, and large-scale rooftop solar projects where fast installation and low structural impact are essential.

Product Overview
The flat roof ballasted solar racking system is engineered by experienced structural designers in accordance with AS/NZS 1170 and other international design standards. It is specifically developed to withstand harsh environmental conditions, including high wind zones and heavy snow regions.
By using concrete ballast blocks for fixation, the system achieves excellent wind resistance while maintaining a simple and efficient installation process. This makes it an ideal choice for projects requiring fast deployment and long-term reliability.
The system is also suitable for installation on flat ground when rooftop mounting is not applicable.

Projects We Have Completed

Unlike traditional roof-penetrating systems, the ballasted solar mounting structure uses concrete blocks to secure the system in place. This approach provides several key benefits:
First, it avoids damaging the waterproof layer of the roof, significantly reducing the risk of leakage. Second, it allows faster installation since no drilling or chemical anchoring is required. Third, it provides strong resistance against high wind loads when properly designed and weighted.
This makes it especially suitable for commercial rooftops where roof protection and installation speed are critical factors.
All components are manufactured using high-grade aluminum alloy and stainless steel materials to ensure long-term durability in outdoor environments. The system is designed and tested according to internationally recognized structural standards, ensuring reliable performance under wind and snow loads.
Each load-bearing component undergoes strict quality inspection to guarantee structural safety and consistent performance across different project conditions.
