Q1: What materials do you support for sheet metal prototyping?
A1: We primarily use cold rolled steel, aluminum, and stainless steel. SPCC and DC01 grades are most common for prototypes.
Q2: How fast can I get my prototype parts?
A2: Typical lead time is 3–7 days depending on complexity and quantity.
Q3: Can I get a single prototype before mass production?
A3: Yes. We support one-off prototypes with full finishing and documentation.
Q4: Do you offer surface finishing?
A4: Yes. We provide powder coating, zinc plating, brushing, polishing, and more upon request.
Q5: Can you manufacture complex assemblies or only single parts?
A5: We do both. Our services include welding, riveting, and mechanical assembly of multi-part components.
