Lacquered brass safety rosette Round
Round lacquered brass security rosette. SKG3 round cylinder rosette for classic front door in stable mirrored brass
A round brass lacquered security rosette is a round cylinder rosette for the front door cylinder hole, made of solid brass with an acrylic lacquer coating. Thanks to progressive polishing followed by a thin protective lacquer layer, the mirror-gold surface remains stable for 5-10 years without patination. The round shape matches round or oval front door hardware (Dieckmann Europa, Kronos, Intersteel round versions, classic sets with rounded elements). The rosette visually covers the cylinder hole. In SKG3 version. Includes a recessed steel core pull ring that blocks core pulling attacks.
At Deurbeslag Expert, you will find 1 round brass-lacquered security rosette from Intersteel in SKG3 version with core pull protection. Lacquered brass for long-term color fastness. Suitable for front door thickness 38-65 mm, M5 fixing, for mounting on SKG2/SKG3 cylinder lock.
Round vs. square. Shape choice
The choice of shape is purely aesthetic:
- Round (this range). Matches round/oval front door hardware, classic villa, Dieckmann Europa/Kronos, 1930s home with rounded facade detailing.
- Square or rectangular (see Square lacquered brass security rosette). Matches square or rectangular front door hardware, modern style.
Core pull protection and SKG levels
Core pulling protection is a recessed steel ring around the cylinder core that prevents a burglar from forcibly pulling the cylinder core out of the lock. Approximately 60% of successful cylinder burglaries in the Netherlands are committed using this method. SKG levels: SKG1 (15 sec, interior door), SKG**® (3 min, PKVW minimum) and SKG***® / SKG3 (5 min, villa-grade). All security escutcheons in this category are SKG3 certified.
Lacquered vs other brass finishes
- Lacquered (this category). Acrylic lacquer coating for a stable mirror finish for 5-10 years; no patination, no maintenance.
- Polished. Mirror finish without lacquer layer, develops a natural patina in 2-5 years.
- Tumbled. Soft matte due to mechanical polishing drum.
- Unlacquered. Open brass with factory shine, freely patinable.
- Titanium-PVD. 15+ years UV stable.
