I'm interested in sourcing annealed wire in 1kg rolls. Could you please provide details on the available grades, wire gauge options, and pricing for larger orders? It would be helpful to know your lead times and any minimum order quantities you may have as well. Additionally, I'm keen to understand the packaging options and the shipping methods you offer. If possible, please send over any product specifications or certifications related to the annealed wire. This info will assist me in making a well-informed purchasing decision. Looking forward to your prompt response!
