Our wire rod coils feature a uniform round cross-section, controlled cooling, and consistent mechanical properties along the entire coil length. The surface is smooth and free from harmful defects such as cracks, scabs, seams, and excessive scale. YS STEEL can supply coils with standard or customized inner diameters, coil weights, and packaging configurations to match different production line requirements.
The following technical parameters define the standard range of steel wire rod supplied by YS STEEL. We also manufacture non-standard sizes and special grades according to customer drawings or specific application requirements.

We can produce according to GB, ASTM, JIS, DIN, and EN standards. If you need a special chemical composition, please contact our technical team with the required specification.
Yes, YS STEEL can customize coil weight from 1.8 metric tons up to 3.0 metric tons per coil, depending on diameter and grade. The inner diameter can be set at 850 mm, 1100 mm, or 1250 mm to suit different pay-off systems. Custom coil weight helps reduce loading and unloading frequency, improves processing efficiency, and lowers overall handling costs. We recommend discussing your equipment specifications with our sales team so we can configure the coil dimensions correctly before production begins.
YS STEEL is certified to ISO 9001 for quality management and ISO 14001 for environmental management. Our products are accepted under international standards such as GB, ASTM, JIS, DIN, and EN. We also support third-party inspection by SGS, BV, Intertek, or other agencies. Each production lot is accompanied by a mill test certificate that includes chemical composition, mechanical properties, dimensional checks, and surface inspection results. This documentation ensures traceability and compliance with your contract requirements.
The minimum order quantity for steel wire rod is typically one 20-foot container, which holds approximately 25 to 28 metric tons depending on coil size and packaging. For mixed sizes or special grades, smaller trial orders may be possible with advance coordination. Production lead time is usually 15 to 30 days after receiving the deposit or an irrevocable letter of credit, depending on the grade, quantity, and current production schedule. Please contact YS STEEL with your target delivery date so we can provide an accurate timeline.
YS STEEL ensures consistent quality through strict raw material selection, precise furnace temperature control, high-speed no-twist rolling, controlled cooling on a Stelmor conveyor, and systematic inspection of every coil. We test chemical composition using optical emission spectrometry, check tensile strength and elongation with calibrated universal testing machines, and perform visual and dimensional inspection for surface defects and tolerances. This multi-stage quality control system reduces variation between heats and coils, which helps prevent breakage and downtime in your downstream processes.
