I'm looking for galvanized steel with a thickness of 35 gauge. Specifically, I need information on the material's availability, specifications, and pricing. It would be great if you could also provide details on the production lead times and any minimum order quantities that apply. Additionally, I would appreciate if you could share your options for surface treatments or finishes, as well as packaging details for shipping. If there are any certifications or quality assurance processes in place, please include that information as well. Looking forward to your prompt response with the relevant details!
