At a glance
Composite street furniture needs an application-specific assessment. A successful decking test does not automatically validate a bench slat or its attachments.
Key points
- Structure: Slat span and concentrated loads.
- Comfort: Surface, edges and temperature.
- Maintenance: Inspectable and replaceable parts.
The technical principle #
A seat can experience concentrated loads, long unsupported lengths and repeated use. Creep and temperature can affect deflection, while fixing restraint influences movement. Cut edges, local bearing and fastening locations deserve attention because they differ from a continuously repeated decking layout.
What to specify and verify #
Specify the actual slat dimensions, support spacing, attachment detail and intended use. Ask for relevant evidence for the completed furniture or an appropriate engineering assessment. Plan drainage, comfortable contact surfaces, inspection access and replacement of individual components rather than replacement of an entire installation.
Application and common mistakes #
Green Plank publishes Nordic public-furniture references that can help frame a project discussion. Request drawings, installation dates and maintenance observations for a comparable application. Do not infer that a historical seat profile validates a different modern board or that the number of city benches equals the supplier's installed quantity.

Common questions
Can any decking board be used as a bench seat?
No. The seat geometry, support and attachment need verification for the intended public use.
