Frequently asked questions
Can I order a custom diameter, coating and tensile grade?
Yes. Zhongbo manufactures to your specification — wire diameter, zinc-coating weight, tensile grade, temper and finish. Send your requirement and we will confirm what we can produce.
Do you provide samples before a bulk order?
Yes. Samples or small initial quantities are available so you can evaluate diameter tolerance, coating, tensile strength and surface quality before placing a larger order.
Which standards do you manufacture to?
ASTM A641, EN 10244-2, BS EN 10257, JIS G 3547, AS/NZS 4534 and GB/T, or your own customer standard and test plan.
What is the minimum order quantity and lead time?
MOQ and lead time depend on the diameter, coating and quantity. Send your enquiry with the destination port and we will confirm both with the quotation.
Do you provide mill test certificates and third-party inspection?
Yes. Each shipment can include a mill test certificate covering diameter, tensile strength and zinc-coating weight, with SGS, BV or customer-appointed inspection on request.
