巴基斯坦采购需求：镀锌自攻螺钉、铝用自钻螺钉、自钻技术螺钉、自攻砖螺钉、不锈钢自攻螺钉、紧固件类型

I'm looking for a supplier who can provide a specific type of self-drilling screw, ideally with a galvanized finish and a truss head design. The size I have in mind is quite common, but I'm open to discussing variations if available. Please share your product specifications, including materials, sizes, and any certifications that your screws might have. Could you also provide me with pricing details, minimum order quantities, and lead times for delivery? I'm interested in establishing a reliable partnership for ongoing orders, so any information regarding your production capabilities and logistical support would be greatly appreciated.
