Fantech FR Series Galvanized Flange Ring
Fantech's FR Series uses galvanized steel to deliver enhanced corrosion protection and a longer service life, making it a market-leading selection for light commercial and demanding residential installs. It commands a modest price premium over basic steel rings like the Broan-NuTone FMR6 but offers better longevity in moist or industrial environments, while remaining more economical than some specialty European metal rings from brands such as Soler & Palau.

Vents VKF Plastic Flange Ring 125mm
The Vents VKF plastic flange ring is the economical, corrosion-proof option for simple domestic installations and DIY projects where budget and resistance to moisture are priorities. While it lacks the mechanical strength and heat tolerance of metal rings (Broan-NuTone, Fantech, Soler & Palau) and cannot match the lightweight corrosion resistance of aluminum (Master Flow), its low cost and ease of installation make it the best value choice for non‑industrial use cases.

Master Flow SMF6 Aluminum Flange Ring
The Master Flow SMF6 uses aluminum to offer a strong but lightweight flange ring with excellent corrosion resistance—an attractive middle ground between heavy steel and inexpensive plastic. It typically sits at a mid-to-premium price point, providing superior longevity in coastal or corrosive environments compared with steels like Broan-NuTone and galvanized Fantech rings, while being lighter and easier to handle than many Soler & Palau metal options.
