Siedle Steel
Maximum quality, individually produced: Each Steel system is configured and manufactured as a unique piece according to the customer’s specifications. The first of our two design aims is maximum freedom. Perfection is the second. An aim that accepts no compromises.
Design freedom
High-class and robust: PVD coatings
Iridescent copper, noble brass, striking titanium and elegant black – the extremely thin PVD coating emphasises the texture of the Siedle Steel stainless steel. It is scratch-resistant, weather-resistant and easy to clean.
Siedle Steel function modules

The loudspeaker and microphone form the basis of every intercom system. Siedle offers perfect voice quality, even in noisy environments.

Light and call buttons in backlit plastic, made of solid metal with laser lettering or engraving – filled in black on request.

The alternative to standard buttons. Made from the solid metal of the front panel, these are clearly identifiable and easy to use.

This camera’s horizontal pick-up angle of 130° is the perfect choice for most standard applications at the entrance.

With its large horizontal field of view of 175°, the camera 180 covers almost the entire entrance area, thereby offering maximum security.

Made from the front panel material, solid, brushed or coated surface.

The contrasting mounting level becomes visible through the lasered cutouts in the solid front panel.

Opens the door or serves as a control centre for everything with a switching function. If combined with a user list in the info module, the code lock also works as a call system.
Siedle Steel letterboxes

The post falls into a shaft and is removed from within the building. The pass-through flap is made of the front panel material. The flap closes softly, so you can say goodbye to irritating rattling!

Clever construction: The removal door opens to the front rather than to the side; the post is held securely and does not fall to the floor. The pass-through flap and removal door are made of the same material as the front panel.

The free standing pedestal with receipt of post is typical and true to form for Siedle Steel: The letterbox housing with front removal only protrudes as much as required to do its job.

Siedle letterboxes do much more than just hold post: They offer damp and removal protection, a mail notification system, electrical unlocking, a delivery box for parcels and much more.
Materials and colours for Siedle Steel
Stainless steel, aluminium and brass are the base materials for the solid front panels. Left natural or finished, they give Siedle Steel a striking appearance.

The basic equipment: Corrosion-resistant V4A stainless steel, front panel brushed lengthways, buttons and control elements brushed crossways. Mounting level in individual color.

The burnishing, an intentional oxidation, is uneven and forms a characteristic patina.

The Steel front panel made of aluminum is anodized in natural color or equipped with the robust Duraflon coating.

The Steel front panel paintwork finishes in any RAL colour or with micaceous finish fulfil the highest requirements.

Timeless and contemporary at the same time: The warm tone of the PVD coating copper. Scratch-proof and easy to clean.

The brass PVD coating impresses with its perfect surface and brilliant color quality.

The striking grey of the titanium emphasizes the structure and processing quality of the base material particularly well.

Extremely thin and extremely robust: the PVD coating for Siedle Steel in elegant black.
