What are soil profiles?

Floor profiles and seals close the gap between the bottom edge of the door and the floor or the lintel. They improve sealing, energy efficiency, hygiene , and protect sensors and mechanics. These include:

  • Floor rubbers – for optosensors, DW contacts (round inner chamber), 8k2 safety edges, OSE/OS systems
  • Top rubbers – camber/head gaskets
  • Plugs, start/end connections – for DW/8k2 systems
  • Side seals – between door leaf and rail
  • Wicket door seals – for integrated doors
  • Threshold/floor mounting profiles – for uneven floors

Note: Prices/list values ​​are irrelevant here – the focus is on technology, fit & use.

Areas of application & benefits

  • Industrial gates – warehouse/logistics, production, ramps
  • Sectional doors – halls, workshops, parking buildings
  • Roller doors – fast cycles, compensation of uneven floors

Effects: less draft and dust , protection against moisture , better indoor climate , longer service life of the door system.

Product types at a glance (examples from this collection)

Floor rubbers – Opto / Standard

Designed for optosensors , ensuring clean cable/sensor routing within the chamber. Examples: "Floor rubber for optosensor standard," "Jansen PU."

Floor rubbers – DW (round inner chamber)

Round chamber (e.g., 25 mm or 37 mm ) for DW contact strips . Plugs and start/end connections available.

Floor rubbers – 8k2 / OSE

For 8k2 safety edges including start and end connections. OSE/OS variants available (e.g., Crawford/Normstahl OSE).

Top rubbers

Header/lintel seal in 36 mm, 52 mm, 65 mm, 97 mm , etc. (e.g., Crawford, Hörmann). Closes the upper end.

Side seals & wicket door

Side seal (also as a set), hose/sealing rubber for wicket doors (white).

Brand-specific & universal

Compatible profiles for Hörmann, Crawford, Novoferm, Alpha Deuren , and others; also universally applicable.

Compatibility by manufacturer (excerpt)

Manufacturer Typical profiles Notes
Hörmann SPU 30/40 floor rubber (IDD-HO compatible), top rubber Pay attention to chamber size & sensor (Opto/DW/8k2)
Crawford / Normstahl Bottom rubber, OSE/OS, top rubber 65–97 mm OSE variant managed separately
Novoferm Bottom rubber, top rubber Select the “Novoferm floor rubber” variant
Alpha Doors Floor rubber (Opto), roll goods Consider opto-cable routing
Universal Thresholds/floor profiles, side seals, wicket door seals Check dimensions, chamber diameter & sensors

Tip: Always check the chamber dimensions , sensor type (Opto/DW/8k2) and door manufacturer .

Comparison: Opto / DW / 8k2 – which type is right for you?

type Sensor/Connection Chamber dimensions (examples) Mission
Opto Optosensor cable in chamber depending on the profile (e.g. Opto standard) General safety edge with optical trigger
DW Pressure wave (round) in chamber 25 mm / 37 mm Mechanical pressure wave systems; plugs & ends required
8k2 Electrical resistance 8.2 kΩ system-dependent Electrical safety edges; start/end connection required

Frequently Asked Questions (FAQ)

How do I find the right floor rubber?

Check the door manufacturer, chamber dimensions (e.g., 25/37 mm), sensor type (opto/DW/8k2), and installation situation (sectional/roller door). Then select based on the type.

What is the difference between Opto, DW, and 8k2?

Opto uses a light signal, DW uses a pressure wave in the chamber, and 8k2 uses an electrical resistance strip. The profile type must match the sensor technology.

Do I need plugs or connectors?

Plugs and ends are mandatory for DW ; start and end connections are mandatory for 8k2 . For opto, clean cable routing is important.

Is it available in rolls and by the meter?

Yes, many profiles are available by the meter and in rolls (e.g., 25 m / 50 m / 35 m). Selection based on needs and project size.

Does the profile fit my manufacturer?

We offer profile- and manufacturer-specific versions (e.g., Hörmann, Crawford, Novoferm, Alpha Deuren) as well as universal solutions. If you're unsure, please feel free to inquire .

Do you need help choosing?

Send us the door manufacturer, chamber dimensions and sensor type – we will recommend the right profile including accessories (plugs, start/end connection, side seals).
