To guarantee mutual interest, official production drawings and production quantity in compliance with national standard are required by our Company to make offers. Requirements including materials standard, surface treatment, heat treatment and hardness must be indicated in drawings. In case of complicated requirements, attachments can be submitted. If customers fail to provide production drawings, we can prepare such drawings for you provided that the prepared ones must be approved by customers.

Once the drawings are confirmed, we will make quotation within 24 hours.
