Frequently Asked Questions (FAQ)
-
Q: What types of stainless steel can you work with?
A: We commonly process 304, 316, 430, and 201 stainless steel. We can also source specialty grades like 316L or duplex upon request. Please let us know your corrosion resistance or strength requirements.
-
Q: What is the maximum size of parts you can laser cut?
A: Our standard laser cutting bed handles sheets up to 3000×1500 mm. For larger parts, we can discuss custom fixturing or progressive cutting strategies. Contact us with your dimensions.
-
Q: How do you ensure the quality of welds?
A: We perform visual inspection on every weld, and for critical applications we offer X-ray or dye-penetrant testing. Our welders are certified to AWS D1.1/D1.6 standards. We also maintain weld procedure qualifications (WPS/PQR) as needed.
-
Q: Do you offer assembly services for complex structures?
A: Yes, we provide full assembly including riveting, fastening, and sub-assembly integration. We can assemble parts with up to 500 components, complete with hardware and instructions. We also offer packaging and labeling for drop-shipment.
-
Q: What is the typical lead time for a custom order?
A: Lead times vary based on complexity and quantity. A simple prototype can be completed in 2–3 weeks, while a large production run may take 4–6 weeks. We provide a detailed schedule during the quotation phase.
-
Q: Can you help with design optimization to reduce cost?
A: Absolutely. Our engineers provide free DFM (Design for Manufacturing) feedback. We can suggest material changes, bend radii, hole patterns, or joining methods to lower production costs without compromising quality.
-
Q: Do you have any certifications for quality management?
A: Yes, we are ISO9001:2015 and ISO16949 certified. These certifications ensure our processes are standardized, traceable, and continuously improved. We can provide certificates upon request.
-
Q: How do I get a quote for my custom stainless steel structure?
A: Simply send us your 2D/3D drawings (PDF, DXF, STEP, or IGS) along with material and quantity requirements. We will respond within 24 hours with a competitive quote and technical suggestions. You can also request a sample or prototype first.
