Aluminium-Clad Steel Wire (ACS Wire)
- Diameter range: 1.60 mm to 5.50 mm
- Conductivity grades: LB14 to LB40, LBY10 to LBY14
- Combines high strength of steel with corrosion resistance of aluminium
- Used in aluminium-clad steel strand, OPGW, overhead ground wire, preformed fittings, fencing, and marine environments
- Conductivity Grades: 14%, 20.3%, 23%, 27%, 30%, 35%, 40% IACS
Aluminium-Clad Steel Wire (ACS) is a bimetallic conductor composed of a steel core surrounded by a uniform layer of aluminium. It combines the high mechanical strength of steel with the superior corrosion resistance and electrical conductivity of aluminium. ACS wire is ideal for applications requiring durability and conductivity in harsh environments, such as OPGW, ground wires, coastal fencing, and preformed products.

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?
