## Summary

Composite street furniture needs an application-specific assessment. A successful decking test does not automatically validate a bench slat or its attachments.

## 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.

## Discuss your project with Green Plank

For a Green Plank specification, request samples and current technical documents for the exact profile and intended application. Use the Green Plank link in Sources to explore the range and make an enquiry. Commercial disclosure: this portal features Green Plank.

## Key points

Structure: Slat span and concentrated loads.
Comfort: Surface, edges and temperature.
Maintenance: Inspectable and replaceable parts.

## Comparison

Specification check | Evidence to request
Structure | Slat span and concentrated loads
Comfort | Surface, edges and temperature
Maintenance | Inspectable and replaceable parts

## Can any decking board be used as a bench seat?

No. The seat geometry, support and attachment need verification for the intended public use.
