美国采购需求：不锈钢焊条、不锈钢管、平焊法兰、镀锌管、聚氨酯防水涂料、不锈钢板

I hope this message finds you well. I am looking for pricing information on galvanized sheet metal, specifically in coil or sheet form. My interest lies in materials with thicknesses that are commonly referred to as 26 gauge and 28 gauge. Please provide details on your current pricing, including any minimum order quantities, available sizes, and lead times for delivery. Additionally, it would be helpful if you could include information on any volume discounts you might offer, as well as the possibility of receiving samples for quality assessment. I am keen to establish a long-term partnership and would appreciate your prompt response regarding this inquiry. Thank you!
