Solar photovoltaic profiles
Aluminum square tubing boasts properties such as water resistance, moisture resistance, environmental friendliness, energy efficiency, rust resistance, and corrosion resistance.
Suitable for engineering applications on exterior walls, subway stations, railway stations, clubs, gardens, exhibition halls, offices, airports, and other public spaces.
In addition to the aforementioned public‑building applications, this lightweight, corrosion‑resistant photovoltaic aluminum profile has become a core, highly sought‑after material in today’s PV industry supply chain. Compared with traditional steel PV racking and framing systems, it weighs only about 30% of equivalent‑volume steel. While ensuring structural strength meets design requirements, it significantly reduces roof‑load stress, making it ideally suited for distributed PV installations—such as color‑steel‑tile‑roofed factories and older residential buildings—with limited load‑bearing capacity. It also simplifies handling and assembly during construction, enabling rapid on‑site installation without the need for heavy‑duty lifting equipment, thereby shortening project timelines and lowering labor costs. Moreover, its surface undergoes a specialized anodizing and sealing process that effectively resists rust, deformation, and surface flaking—even under prolonged exposure to the harsh conditions of desert and gobi regions or the high‑salinity, salt‑laden environments of eastern coastal areas. With a stable service life exceeding 25 years, it fully aligns with the operational demands of a PV system’s entire lifecycle, requiring virtually no additional maintenance such as anti‑corrosion coatings or component replacements. Over time, this translates into substantial savings on ongoing O&M expenses for project developers, and it is already widely deployed across ground‑mounted utility‑scale PV plants, residential distributed PV systems, and BIPV integrated building‑PV projects.
Against the backdrop of the industry-wide drive to reduce carbon emissions across the entire photovoltaic value chain and build a circular economy, the comprehensive value of this lightweight, corrosion‑resistant PV aluminum profile is becoming increasingly evident: its manufacturing process employs high‑precision CNC extrusion to tightly control tolerances, and it offers customized tooling services tailored to the specific mounting dimensions and load‑bearing requirements of each project. As a result, it can seamlessly integrate into automated production lines for mass assembly without the need for additional post‑processing or fine‑tuning, significantly lowering processing and adaptation costs for midstream module manufacturers. More importantly, aluminum is a 100% recyclable material; even at the end of a PV system’s 25‑year lifecycle, the retired aluminum profiles can be remelted and reprocessed into virgin industrial aluminum, achieving a recovery rate of over 95%—far surpassing the recycling potential of conventional steel. This aligns perfectly with the photovoltaic industry’s core commitment to green, zero‑carbon development. Today, many leading PV integration service providers have already designated such aluminum profiles as standard core materials for PV racking and frame products, further fostering a virtuous cycle that optimizes initial capital expenditures, operation and maintenance costs, and residual asset value. In doing so, they help investors build long‑term, low‑risk, high‑return green PV assets.
