When does on-site production make sense?
When transport volume, programme or remote location make factory supply impractical, the machine goes to site and sheaths are produced on the project.
On-site production is used when transport volume, delivery programme or a remote location make factory-only supply impractical. The machine is installed; operator training and optional supervisor support are part of the service path.
Steel may be supplied from Türkiye or assessed from local sources against technical requirements. On-site output should not be confused with published factory metres per day; site output depends on setup and programme.
In the RFQ, state the site address, estimated metres, size/thickness and installation window so machine configuration and support scope can be defined.
