BHV flat oval spiral duct features our 4 ply lockseam for
strength and airtight construction, and is available in both plain
and double beaded profiles.
Our flat oval duct is available in single and double wall in
galvanized steel, stainless steel, and poly vinyl coated steel. Call
for details.
Flat oval duct features the best characteristics of both
rectangular and round duct. It fits in spaces too confined for round
duct but can be joined using the simpler round duct assembly
techniques, and has considerably less flat surface area susceptible
to vibration and deflection.
BHV flat oval duct is machine formed from our round spiral duct
using sizing mandrels which provide exceptional dimensional
consistency. We can also ovalize our longitudinal seam duct using
the same process. |
