Product Q&A
Q:Can your products meet local standards or provide detailed production drawings?
A:
Yes, we focus on OEM and ODM service. Our R&D team consists of 12 professional engineers who can create custom power line joints, utility poles, and cable hardware based on your technical drawings, samples, or specific international standards (such as IEC, ASTM, BS, and FRM). We provide relevant drawings for your approval before mass production.
Q:How can the quality and durability of outdoor products be ensured?
A:
Quality is our top priority. We conduct rigorous testing on every batch, including raw material chemical analysis and mechanical tensile strength testing. For all steel structural components, we use controlled hot-dip galvanizing technology to ensure the zinc coating thickness exceeds standard values of 85 microns. This ensures protection in harsh outdoor environments, reliably corrosion-resistant for many years.
Q:What are your standard delivery times and minimum order quantities? What payment methods do you accept?
A:
Our usual production lead time is 15 to 30 days. We offer flexible minimum order policies to support pilot orders for large infrastructure projects and new distributors. We offer direct factory transportation services to major international ports and provide comprehensive support, including FOB, CIF, CFR, and DDP. Payment terms include 30% prepaid and 70% before shipment.
Q:What is the zinc coating thickness for the hot-dip galvanizing process?
A:
We ensure the zinc coating thickness exceeds standard values of 85 microns for all steel structural components to guarantee protection in harsh outdoor environments.
