美国采购需求：停车柱、路障、除胎器、自动旗杆、升降柱、自行车停车架

I'm interested in your range of bollards and would like to get more details. Specifically, could you provide me with your wholesale pricing structure and any volume tiers you have available? Understanding the price breaks for larger orders would be really helpful. Additionally, if there are any customization options or lead times I should be aware of, please include that info. Looking forward to your response so we can explore potential collaboration!
