I hope this message finds you well. I'm looking to explore the bulk purchase options available for cutting walls. Specifically, I would like to understand your pricing structure, minimum order quantities, and any discounts available for larger orders. Additionally, it would be helpful to know about lead times, payment terms, and shipping logistics to ensure a smooth transaction. Could you also provide details about the specifications and quality standards of the cutting walls? Knowing the materials used and any certifications your products hold would be beneficial. I'm eager to establish a long-term partnership and would appreciate any promotional materials or catalogs you can share that detail your offerings. Looking forward to your prompt response!
