Why Choose a PVD Finish?
PVD coating is a vacuum-bonded finish applied at the molecular level, making it significantly harder and more scratch-resistant than conventional brass plating. It resists tarnishing, UV exposure, and the humid South African coastal climate — making it a smart long-term investment for high-traffic doors.
Frequently Asked Questions
What is a projection hinge?
A projection hinge is designed to project the door clear of the frame architrave when opening, allowing the door to swing to a full 180° without obstruction. This makes them especially useful for wide or heavy doors where maximum clearance is needed.
What is PVD and why does it last longer than standard brass plating?
PVD stands for Physical Vapour Deposition — a vacuum coating process that bonds metallic particles directly onto the stainless steel substrate. The result is a finish that is 2–3× harder than traditional electroplating, highly resistant to scratches, tarnishing, and corrosion, and suitable for both interior and exterior use in South Africa's varied climates.
Are these hinges sold individually or as a pair?
The QS4412/3PVD is sold as a pair. Standard door installations typically require 3 hinges — order 1.5 pairs, rounding up to 2 pairs for a complete set of 3 or 4 hinges per door.
Are these hinges suitable for exterior doors?
Yes. The stainless steel core combined with the PVD finish makes the QS4412/3PVD highly resistant to moisture and corrosion, making it suitable for exterior door installations including coastal environments.
