Applications and Uses of Galvanized Spiral Ducts

Blog | 10 August 2017

Galvanized spiral ducts are manufactured from aesthetically pleasing lengths of polished metal. Visually appealing by design, the locking seam coiling around the ductwork sees the pipes installed as decorative artifices, perhaps as a steel jacket on a concrete pillar. On the flip side of such architectural utilization instances, this is also an HVAC ducting solution, one that excels due to that spiral configuration.

Contemporary Ventilation Channels 

The spiral design does look attractive, but it’s actually there to serve a purpose, not just to look good. Remember, lightweight metal tubes sag between their fastening hangers, but that dip never takes place here because the seam acts as a supporting backbone. Those interlocking metal sheets, cleverly fabricated by structural engineers, are basically using the spiral configuration as a reinforcing “rib,” a structural asset that keeps every channel run absolutely rigid. Employed on ceilings and wall spaces where fastening joints are sparsely installed, the attractive ducting is guaranteed to maintain its rigid outlines.

Embedding Industrial Accents 

When tall concrete pillars lose their appeal, then galvanized spiral ducts are the answer. Jacketed around the pillars, the ribbed crease coils from top to bottom, until the modern space is charged with a cool alloy-reinforced aesthetic. Additionally, the installation of a working HVAC system, one that’s based on the same architectural format, heightens this industrial style. Form and function are meshing here, not clashing. Of course, an “opposites attract” design ethic also prevails in architectural projects, so look for this compelling metal ductwork in wooden churches, fabric-decorated restaurants, and countless other progressively designed interiors.

Let’s finish by talking about a few active benefits. Galvanized spiral ducting is rigid, but that coiling seam does absorb the thermal properties of the airflow, so it won’t bulge and generate noise, not like traditional rectangular ducting. Therefore, this visually attractive, energy efficient ducting type is as quiet as it is good looking. Next, that rounded ductwork profile doesn’t have any sharp edges. Even the spiral seam is fabricated to sit flush against the tubed metal segments. Curved in this manner, the cylindrical interior is easy to clean. No dust, no dirt, and no mildew-coated stains can hide from a cleaning brush or industrial vacuum cleaner here. Finally, those rounded edges and interlocking seams are designed to eliminate airflow leaks, which means an all-round energy efficiency increase. Fabricated from thin-gauge steel sections and assembled with an interlocking seam, spiral ductwork is now regarded as the superior HVAC channeling solution, plus it’s a popular pillar facade, a material that adds industrial style to prosaic concrete pillars.
