A Natural Fit for 25-Year Service Life
Solar modules are designed to operate for 25–30 years outdoors, in heat, humidity and UV. Aluminium 6063-T5 combines light weight with excellent corrosion resistance — the oxide layer self-heals on exposure to air — which is why extruded aluminium frames and mounting structures have become the default across the PV industry.
PV Module Frames: Precision in Four Corners
Module frames are extruded profiles with carefully engineered grooves and drainage channels, cut and joined at 45-degree corners. Dimensional tolerance matters at the millimetre level: frame squareness and flatness directly affect glass lamination and panel assembly yield. A reliable supplier holds tight tolerances consistently across millions of metres.
Mounting and Racking Systems
For ground-mount and rooftop systems, extruded rails, clamps and brackets carry static and wind loads over the project lifetime. Compared with hot-dip galvanised steel, aluminium racking needs no re-galvanising, weighs less for transport and installation, and offers predictable corrosion performance in coastal and desert environments alike.
Sourcing Aluminium for Solar Projects
Specify the alloy (6063-T5/T6), anodizing thickness (AA10–AA15 for outdoor service), and tolerances on your drawings. For large PV programmes, work with a manufacturer that can scale — Siken Aluminum’s 30,000-ton annual capacity supplies module frames, mounting rails and brackets to solar customers worldwide, from pilot orders to container-volume deliveries.
