Traffic Signal Housing Materials: Polycarbonate vs Aluminum

Compare polycarbonate and aluminum housings for UV exposure, impact resistance, corrosion, sealing and maintenance.

Project review

Select the enclosure as part of a complete signal-head system. Check the approved drawing, outdoor exposure, gasket design, cable entry, compatible fasteners and service access before production.

Buyer checklist

• UV and colour stability
• Roadside impact and vibration
• Corrosion risk and hardware finish
• Gaskets, drainage and cable entries

Document the agreed configuration in the purchase specification so installers and maintenance teams have a reliable reference.
