Profiles
- The bead eases the installation of clamps.
- The supporting leg offers additional stability and, in conjunction with the sturdy corners, reduces the eventual deflection of the frame considerably.
- Also available with injected HD-sealant upon request.
- The dished internal web presses against the duct wall, acting as a metallic self-sealing lip.
- The leading edge (optional) facilitates the insertion of the duct wall into the profile.
Stability of METU Profiles
Deformation Measurements on Rectangular Air-ducts and Parts of the Rectangular Duct Connections: Since their introduction into the market (Patent No. 1 946 547 dated 13.09.1969), the METU-SYSTEM triangular shaped profiles (MM, HM, RM) provide an optimal stability to the rectangular duct connections. The independent MPA tests (only available in German), conducted on October 11th, 1972, proved the superior stability of the METU-SYSTEM profiles when compared to other profiles and rectangular duct connection methods available at that time, including angle iron.
The METU Rectangular duct connection are still considered by many users today to be the strongest on the market, reducing or even eliminating the necessity to use clamps. No Ex or ATEX certifications.
hd = with injected sealant (see also ZI-401)
E = with leading edge (with A).
F = without leading edge (w/o A).
