Small branch ducts cannot carry the combined terminal duty.
The 315 mm passage gives the group branch a larger cross section.
STJH-SPIRAL-GALVANIZED-STEEL-DUCT-DN315
Spiral Galvanized Steel Duct DN315
Medium spiral branch duct with a reinforced sheet thickness.
- Medium bore connects naturally to circular distribution fittings.
- A thicker shell supports a broader passage.
Introducción del producto
The 315 mm round section provides a larger flow passage for groups of terminals. Its galvanized wall is thicker than the smallest branch version, and the continuous spiral seam maintains the cylindrical shape along the straight duct length.
