We ensure that 6005T6 aluminum extrusions meet all the national standards and certifications. Our manufacturing process complies with the standards in China, particularly the GB/T standards on solar panel frames. From the level of functionality, safety, and durability of our extrusions, you can tell that we do take adherence to standards seriously. We adhere to the requirements of GB/T 3190 to ensure that the composition of our alloys is as expected. The GB/T 6892 is yet another guiding standard in the manufacturing process, in this case for the aluminum solar panel frame extrusion profiles.
