约旦采购需求：螺栓、螺母、螺钉、垫圈、锚栓、螺纹杆

I'm reaching out to inquire about the availability and pricing for a specific type of fastener we're looking to source. We have a requirement for a total of 20,000 units of a certain high-strength bolt, with different lengths needed to meet project specifications. The bolts should meet the relevant DIN standard and come with a hot-dip galvanization finish for corrosion resistance. Please provide detailed information regarding your production capabilities, lead times, and pricing options for this quantity. We're particularly interested in any discounts for bulk orders and would appreciate your insights on delivery schedules. If you have any specific recommendations or alternatives that fit our criteria, feel free to include those as well. Looking forward to your prompt response!
