巴西采购需求：石膏板螺丝、碳钢螺丝、卷装螺丝、带状石膏板紧固件、B2B建筑螺丝、散装石膏板材料

I'm an importer working in the Hebei region, and I'm looking to expand my product range. I've come across your offerings and I'm particularly interested in your drywall screws of various sizes, as well as your Carbon Steel Collated Belt Drywall Screws and the necessary adapters. Could you provide more details about the specifications, pricing, and availability of these products? Additionally, if you have any catalogs or brochures, I'd appreciate it if you could send those my way. Looking forward to hearing back from you soon!
