埃及采购需求：钛棒

I'm interested in purchasing titanium alloy rods in specific dimensions of 4mm and 6mm. Could you please provide me with your pricing details for both sizes? Additionally, I would like to know the available options regarding surface treatments or any certifications associated with these products. Furthermore, I need to understand your shipping arrangements to Egypt. Please include shipping costs and estimated delivery times in your response. Your prompt feedback will be greatly appreciated, as I'm looking to finalize this procurement soon. Thank you!
