We are currently looking to source self-drilling screws for an upcoming project. We'd like to inquire about your available options in terms of sizes, materials, and coatings. Additionally, it would be helpful to know your production capacity and lead times for bulk orders. Could you also provide us with your pricing structure, including any discounts for larger quantities? We're interested in establishing a long-term partnership, so information on your quality assurance processes would be appreciated. Looking forward to your prompt response!
