Precision Cutting FAQs
What tolerance can Genn-Hann achieve in precision cutting?
Our precision cutting lines hold tolerances as tight as ±0.01mm across strip, coil, and sheet stainless steel. This level of consistency suits automotive components, precision machinery parts, and construction fittings that require tight dimensional control across production batches.
Which stainless steel grades do you cut and supply?
We process SUS 304, 304L, 301, 316L, 430, 409, and 439 grades in strip, coil, and sheet form, including CSP hardness materials and pre-coated coil. Buyers can specify grade and finish based on corrosion resistance, hardness, or magnetic property requirements for their application.
Are you a precision turned parts supplier, or do you focus on flat-rolled cutting?
Our core capability is precision slitting and blanking of strip, coil, and sheet to ±0.01mm, complemented by cold/hot forging, stamping, and assembly for standard parts such as bolts, nuts, and bearings. If your project needs dedicated CNC turned components, confirm with our team whether your part geometry fits our forming and stamping processes.
What certifications does your production line hold?
Our facility operates under ISO 9001, ISO 14001, ISO/TS 16949, IATF 16949, and ISO 13485 certified processes. This covers automotive, environmental, and medical device quality requirements, giving buyers documented traceability for regulated supply chains.
What industries do you supply most?
Automotive manufacturing and parts supply account for over 60% of our shipments, with the remainder split across industrial machinery/equipment and construction sectors. Our ±0.01mm cutting tolerance and multi-grade stock support both high-volume automotive runs and lower-volume machinery or construction orders.
What is your production capacity and typical lead time?
As a 40-plus year, 50-employee workshop producing under 500 tons annually, we operate as a small-batch, high-precision supplier rather than a mass-volume mill. This structure lets us prioritize tight tolerance runs and custom sizing, though buyers with very high-volume tonnage needs should confirm capacity against their schedule directly with our sales team.
Do you offer custom sizing and finishing?
Yes, we provide custom-sized cutting and polishing/finishing services on top of standard strip, coil, and sheet dimensions. This is used for buyers who need parts ready for direct assembly rather than additional downstream processing.
How many countries do you currently export to?
Genn-Hann ships to more than 50 countries from our Taiwan factory. Buyers can request export documentation and prior shipping regions relevant to their country during quotation.
