Quadro And Sirio Share The Same Family, But Not The Same Look
Quadro and Sirio belong to the same Italian cable-heated family, so the decision is not about a different heating construction. The decision is about shape, profile, and the kind of modern language the room wants to carry.
Sirio uses round, larger-diameter horizontal bars with vertical rails that taper along their inner sides. Quadro uses exclusively square bars. Both are premium hardwired designer collections. They simply express that design style differently.
Sirio
Larger-diameter round horizontal bars with tapered inner rail sides.
Quadro
Square-bar styling with a cleaner, sharper architectural presence.
Because they share the same broader system family, the best way to compare them is by how the rack should look and feel in the room rather than by performance claims.
How Each Collection Reads On The Wall
Sirio
Sirio uses round horizontal bars with a larger diameter than Jeeves. Its vertical rails are rounded on the outside and taper along the inner side into a gentle inward slope.
- Round horizontal bars
- Larger diameter than Jeeves horizontal bars

Quadro
Quadro has a more graphic presence. The square bars give it a stronger outline, which makes the rack feel bolder and more architectural in the room.
- Square-bar profile
- Cleaner geometric expression
- Strong fit with sharper hardware and stronger lines
- More visually assertive than Sirio

What They Have In Common
Construction
Both are cable-heated hardwired collections from the same Italian family, which means the heating construction is closely related.
Controls And Accessories
They share the same broader controller ecosystem and related accessory compatibility, so the comparison usually stays focused on design rather than function.
