土耳其采购需求：铝管，无缝铝管

We are a manufacturer based in Turkey that specializes in wheelchairs and sports chairs. Our focus is on utilizing robust materials that enhance the durability and performance of our products, particularly in the sports chairs segment. We have a specific interest in 7020-T6 aluminum alloy due to its excellent strength and weldability. However, local suppliers have limitations in providing this alloy in the required specifications. We're looking to procure 7020-T6 aluminum alloy with a wide range of diameter options from 10 mm up to 600 mm and wall thicknesses varying from 1 mm to 150 mm. Please provide your available sizes, temper options, and pricing details. We want to explore reliable partnerships to ensure a consistent supply of this essential material for our production needs.
