TEMPER STRETCH™ CUT-TO-LENGTH OVERVIEW VIDEO

Explore the concept and different modes of operation.

Stress Free Flat Rolled Sheets
Commodity Sheets

For production of quality sheets in a broad range of thickness, run with the Roller Leveler. Sheets will be consistently flat (though not stress relieved) and can run up to 84 mpm at +/-0.15 mm length accuracy.

Premium Thin Sheets
Premium Thin Gauge Sheets

For thinner (4 mm or less) sheets that must be stress relieved, run the compact Temper Mill.  The product will have a superior surface, no sign of coil breaks, and will run fast: 61 mpm at +/- 0.15 mm length accuracy.

Premium Steel Sheet and Plate
Premium Heavy Gauge Sheets

Heavy Gauge (up to 18 mm) sheets that must be absolutely laser flat and fully stress relieved will use the Stretcher Leveler. Speeds vary with sheet length, but they will still have +/- 0.15 mm length accuracy.

THE GREAT DEBATE:
TEMPER MILL VS. STRETCHER LEVELER

There are die-hard ‘Temper Mill’ processors and die-hard ‘Stretcher Leveler’ processors . . . and a few who operate one (or more) of each. Compared side-by-side below, it’s clear each has its advantages and disadvantages over the other. That’s why the Temper Stretch CTL Line uses the best of both.
