Hermann-Wimmer - Sweeper Brush Materials

Beech

The bodies of the brushes are made from solid beech wood sourced from local forests.

Plywood

Disc broom bodies are cut from waterproof glued plywood.

Recycled Plastic

Disc broom bodies and broom strips are made from recycled plastic sheet (PP/PE regenerate). When the bristles of the disc brooms are worn out, the bodies are taken back, cleaned of dirt and old bristles and reused.

Polyethylen (PE) / Polyolefine (PO)

Sweeper bodies are made from PE and PO pipes. These materials are neutral to groundwater in landfills and are harmless when incinerated.

Flat steel wire

Flat steel wire is used for the bristles of disc brooms.

We recommend:

• Asphalt: pure flat steel trimming
• Uneven surfaces: Mixed flat steel wire and polypropylene filling
• Low-noise sweeping: Rubber coated wire (natural rubber) for extra noise reduction (whisper broom)

Depending on the surface, a different hardness of wire may be required. This can be varied by material thickness and increased by the use of springs.

Corrugated wire

Corrugated wire mixed with synthetic fibres is only used for sweeping rollers. The use of corrugated wire in sweeping rollers can lead to wire breakage despite the greatest possible care in the selection of raw materials and their processing. In sensitive areas such as farms, schools and nurseries, next to pastures or on interlocking paving, we recommend rollers without corrugated wire.

Polypropylene (PP)

Polypropylene is the plastic commonly used for sweeper brushes.

We recommend bristles made of or with polypropylene for more sensitive surfaces to ensure particularly gentle cleaning.
