Our patented Roll-Flo®,
or "shear" process allows LeFiell to produce variable
wall and diameter tubing sections by forming a tube over a hardened
mandrel. This process not only allows us to hold precise
tolerances over lengths up to 30 feet, but it also yields the
highest possible structural
and mechanical properties possible. Because our equipment
is custom built to our specifications, we are able to Roll-Flo®
diameters ranging from 1/2 inch to 15 inches with a variety of
aircraft alloy steels, aluminum, and titanium.
