Frequently Asked Questions
Find answers about our diamond wire saws — specifications, lead times, OEM/ODM service, global shipping, and after-sales support.
What wire specifications do you recommend for heavily reinforced concrete?
For standard30-50 MPa reinforced concrete, our11.5mm diamond wire with 40 beads/meter delivers the best balance of cutting speed and wire life. For 50 MPa+ or heavily steel-reinforced sections, we recommend the 10.5mm high-density wire with vacuum-brazed beads. Our engineering team can advise on the exact specification once we know your concrete grade, rebar density, and project dimensions.
Can you produce OEM/ODM diamond wire saws with our brand and packaging?
Yes. We support full OEM/ODM service — your brand name, your packaging design, your required wire diameter and bead pattern. Minimum order quantity for OEM service is typically 500 meters, with sample runs available for quality validation before bulk production.
What is the typical lead time for bulk orders?
Standard specifications ship within7-10 working days. Custom OEM orders typically require 15-25 working days depending on specification complexity and order quantity. We provide a firm delivery date in every quotation and share production photos weekly.
Do you ship worldwide, and what logistics methods do you support?
Yes, we ship to30+ countries via sea freight (FCL/LCL), air freight for urgent orders, and express courier for samples. We handle all export documentation including commercial invoices, packing lists, certificates of origin, and CE/ISO documentation for customs clearance.
