Qi Sheng solar aluminum profile nuts are used with PV mounting rails to create secure threaded connections for clamps, brackets, and other mounting hardware. They are selected to match rail slot dimensions and installation methods, supporting efficient assembly and reliable holding performance in outdoor environments.
We supply profile nuts with options designed for compatibility with common rail profiles. Material and surface treatments can be chosen based on project conditions, helping improve corrosion resistance and long-term stability for rooftop and ground-mount systems.

How to Order / Quick Specs
Please include: nut type, rail/profile slot size or drawing, thread size, material requirement, surface finish, quantity, and delivery destination.
