Frequently Asked Questions (FAQ)
1. What is the difference between 304 and 316 stainless steel rods?
304 is a general-purpose grade with good corrosion resistance, while 316 contains molybdenum, offering superior resistance to chlorides (e.g., seawater, salt spray) and acidic environments. Choose 316 for marine or chemical applications.
2. Can you supply rods with a diameter smaller than 5mm or larger than 50mm?
Our standard range is 5-50mm, but we can produce custom diameters outside this range upon request. Please contact us with your specific requirements.
3. What surface finishes are available?
We offer bright polished, brushed, matte, pickled, and passivated finishes. The surface finish can be customized to suit your application, such as a mirror finish for decorative use or a matte finish for industrial parts.
4. How tight are the diameter tolerances?
Standard tolerances are ±0.1mm, but we can achieve ±0.05mm for precision applications. Please specify your tolerance requirements when placing an order.
5. Do you provide technical support for machining and welding?
Yes, our experienced engineers offer free consultation on material selection, machining parameters, welding techniques, and any fabrication challenges. We are committed to helping you succeed.
6. What is your minimum order quantity (MOQ)?
MOQ varies by diameter and length. Typically, 500kg per diameter for standard sizes. Smaller quantities are available for samples or trial orders – please inquire.
7. How long does delivery take?
Lead time depends on order quantity and customization. For standard sizes, 10-15 days after confirmation. Custom orders typically 20-30 days. We ship globally via sea or air.
8. Do you have any certifications?
We are ISO9001:2015 certified. Our quality management system covers production, inspection, and delivery. We can provide a certificate of compliance with each shipment.
