Regular maintenance is essential for ensuring that post & panel signs remain safe, attractive, and effective over time. This article outlines inspection intervals, common issues to look for, and recommended practices for preserving sign integrity.
1. Inspection Schedule
-
Annual Inspections:
All post & panel sign installations should be inspected at least once a year. -
Post-Weather Inspections:
After any strong winds, heavy rainfall, or flooding events, perform additional checks to detect any damage or misalignment early.
2. Foundation and Structural Integrity
- Subsidence and Soil Erosion:
- After rainfall, check for any signs of subsidence.
- Look for uneven posts or soil erosion around the foundations.
- Reinforce foundations if evidence of movement or erosion is found.
3. Wind and Storm Impact
- Impact on Fixings and Supports:
- Storm-force winds can exert significant pressure on the sign face.
- Check that post clips remain tight and intact.
- Inspect the aluminium sign channel on the sign blank:
- Ensure that flush rivets are secure and not pulling through.
- Verify that the structural bonding tape is in good condition.
4. Post Material-Specific Maintenance
Steel Posts (Galvanised or PVC-Coated)
- Prevention of Rust:
- An external sign cap is crucial to prevent water ingress, which can lead to rust from the inside out.
- Regularly check for any signs of rust, as corrosion can compromise the structural strength of the posts over time.
Aluminium Posts
- Chemical Erosion Concerns:
- Although aluminium does not rust like steel, it can suffer from chemical erosion.
- In environments such as car parks or pathways where rock salt is used, inspect the base of aluminium posts for pitting or structural weakening.
5. Sign Face Cleaning
- Maintaining Visibility and Longevity:
- Keep the sign face clean to enhance both its appearance and its longevity.
- In areas prone to mildew and mould, use a mild detergent for cleaning.
- Always consult the print warranty or manufacturer's specifications to ensure the cleaning method is appropriate for the sign material.
Conclusion
A routine maintenance program not only preserves the functionality and appearance of your post & panel signs but also ensures safety and compliance with industry standards. Regular inspections—especially following severe weather conditions—and timely remedial actions can significantly extend the lifespan of your sign installations.
