I'm interested in exploring your offerings for a range of nuts, bolts, and screws made from galvanized iron. Specifically, I'd like to get detailed information on the available sizes, specifications, and any variations you might have. It's important for me to understand the options you provide, including any standards or certifications the products meet. Additionally, please share your pricing structure, including bulk order discounts, lead times for delivery, and any minimum order quantities. If you have a product catalog or samples, that would be incredibly helpful for evaluating our potential partnership. Looking forward to your prompt response so we can discuss this further!
