"Cut-to-length" (CTL) refers to a mechanized logging system where trees are felled, delimbed, and cut to specific lengths at the stump. This contrasts with tree-length logging, where trees are felled and transported to a landing before being processed. CTL is common in plantation forestry and is often used in Europe. In metal processing, cut-to-length also refers to a process where coiled metal is uncoiled, cut to specified lengths, and then compressed into sheets or plates. In Logging:

• Cut-to-Length (CTL) logging: involves a harvester that fells, delimbs, and cuts trees into desired lengths at the stump.
• A forwarder then transports the logs to a landing area.
• This method is efficient for plantation forestry and in areas where tree sizes are manageable for the harvester.
• It contrasts with tree-length logging where trees are transported whole to the landing area for processing.
• CTL logging leaves slash (branches and tops) at the stump, which can impact fire risk. 

In Metal Processing:

• Cut-to-length lines are used to process flat-rolled metal. 
• Coils of metal are uncoiled and fed through a machine that cuts them into specific lengths. 
• The cut pieces are then compressed and flattened into sheets or plates. 
• This process is used in various industries, including automotive, construction, and electrical.
