Why Do Street Lighting Columns Need Protective Coatings?

Street lighting columns are commonly installed in exposed outdoor environments where metal surfaces experience continuous weathering.

Over time, environmental exposure can contribute to corrosion, coating deterioration and surface damage.

Common factors include:

  • Rain and moisture

  • Atmospheric pollution

  • Road spray

  • De-icing salts

  • UV exposure

  • Temperature fluctuations

  • Mechanical damage

  • General weathering

The severity of exposure can vary significantly depending on the column's location.

A lighting column installed in a sheltered residential area may experience different conditions from one positioned beside a heavily trafficked road or near a coastal environment.

Protecting Street Lighting Columns Against Corrosion

Corrosion protection is a primary consideration when specifying coatings for steel lighting columns.

Without suitable protection, exposed steel can corrode when subjected to moisture and oxygen.

A correctly specified coating system can help protect the substrate and reduce the risk of premature coating deterioration.

The appropriate system should consider:

  • Substrate material

  • Environmental corrosivity

  • Required durability

  • Surface preparation

  • Existing protective treatments

  • Application conditions

  • Maintenance requirements

Anti-Corrosion Coatings for Steel Lighting Columns

Steel lighting columns may require protective coating systems designed for long-term atmospheric exposure.

Depending on the project specification, these systems may involve primers, intermediate coats and protective topcoats.

Industrial Primers for Lighting Columns

Primers form an important part of many corrosion protection systems.

Depending on the product and specification, suitable primers may provide:

  • Adhesion to properly prepared steel

  • Corrosion protection

  • Compatibility with subsequent coats

  • A foundation for the protective coating system

The correct primer should be selected according to the steel substrate, preparation standard and required performance.

Protective Topcoats for Lighting Columns

Protective topcoats provide the exposed finish of many coating systems.

Depending on the product, suitable properties may include:

  • Weather resistance

  • UV resistance

  • Colour retention

  • Gloss retention

  • Abrasion resistance

  • Resistance to environmental contamination

Not every coating provides all these properties.

The selected topcoat should be compatible with the underlying coating system and suitable for the intended service environment.

Coatings for Galvanised Street Lighting Columns

Galvanised steel is commonly used for street lighting columns because the zinc coating provides corrosion protection.

However, additional paint systems may be specified for appearance, identification or supplementary corrosion protection.

A protective paint system applied over galvanised steel is commonly referred to as a duplex coating system.

Why Paint Galvanised Lighting Columns?

Additional coatings may be specified to:

  • Provide a required colour or finish

  • Improve the appearance of lighting infrastructure

  • Offer supplementary protection in suitable environments

  • Meet project or local authority specifications

  • Support refurbishment of existing columns

The benefits depend on the coating system, surface condition and environmental exposure.

Preparing Galvanised Steel for Coating

Galvanised steel requires suitable preparation before painting.

Depending on its condition, the surface may contain:

  • Oil and grease

  • Dirt and contamination

  • Zinc corrosion products

  • Surface treatments

  • Moisture

  • Existing coatings

The correct preparation method should follow the requirements of the selected coating system.

Applying an incompatible coating or failing to prepare the galvanised surface properly can result in poor adhesion.

Protective Coatings for Street Lighting Column Bases

The base of a street lighting column can experience particularly demanding exposure conditions.

Depending on the installation, column bases may be exposed to moisture, road spray, de-icing salts, soil contact and water accumulation.

These conditions can contribute to corrosion where suitable protection is absent or has deteriorated.

Why Are Column Bases Vulnerable?

Potential factors include:

  • Persistent moisture

  • Road splash

  • De-icing salts

  • Surface damage

  • Coating deterioration

  • Water accumulation

  • Contact with surrounding materials

The exposure conditions can vary depending on the column design and installation method.

Coating Systems for Column Bases

Column bases may require protective systems designed for their specific exposure conditions.

The coating specification should consider whether the surface is:

  • Above ground

  • At ground level

  • Embedded in soil or concrete

  • Exposed to standing water

  • Subjected to road salt contamination

A coating suitable for general atmospheric exposure may not be suitable for buried or continuously wet surfaces.

Where columns have specialist foundation or below-ground protection requirements, the system should be assessed against the relevant project specification.

Protective Coatings for Coastal Lighting Columns

Street lighting columns installed near coastal environments may experience increased exposure to airborne salts and moisture.

These conditions can contribute to accelerated corrosion of unprotected steel.

Corrosion Protection in Coastal Environments

The appropriate coating system should consider:

  • Distance from the coast

  • Exposure to salt-laden air

  • Prevailing weather conditions

  • Surface preparation

  • Required durability

  • Maintenance accessibility

For suitable atmospheric corrosion protection applications, ISO 12944 provides a framework for classifying environmental corrosivity and selecting protective coating systems.

The actual corrosivity category should be established according to the project's exposure conditions.

Protective Coatings for Highway Lighting Columns

Highway lighting columns can experience demanding conditions due to weathering, traffic-related contamination and exposure to road spray.

Potential challenges include:

  • Moisture

  • Road salts

  • Atmospheric pollution

  • UV exposure

  • Mechanical damage

  • Coating wear

The coating system should be selected according to the column's construction, location and relevant highway authority requirements.

Coating Requirements for Highway Infrastructure

Highway infrastructure projects may have specific coating specifications and approval requirements.

These can relate to:

  • Surface preparation

  • Coating system selection

Coating Fabricated Components Before Installation

Where appropriate, components can be prepared and coated before leaving the fabrication workshop.

This can help manufacturers manage application conditions and inspection.

The coating specification should account for potential damage during transport and installation.

Surface Preparation for Street Lighting Column Coatings

Surface preparation is essential to the performance of protective coatings.

Even a high-performance coating can fail prematurely when applied to contaminated or poorly prepared metal.

Before coating, the substrate should be assessed for:

  • Rust and corrosion

  • Oil and grease

  • Dirt and dust

  • Loose coatings

  • Moisture

  • Soluble salt contamination

  • Surface defects

Preparing Bare Steel Columns

Depending on the specification, steel preparation may involve:

  • Cleaning and degreasing

  • Mechanical abrasion

  • Power-tool cleaning

  • Abrasive blasting

  • Removal of corrosion

  • Soluble salt testing and removal

The required preparation standard should be established before coating begins.

Preparing Previously Coated Columns

Existing lighting columns may have aged or damaged protective coatings.

Before applying a new system, assess:

  • Existing coating adhesion

  • Corrosion

  • Surface contamination

  • Coating compatibility

  • Areas of exposed metal

  • Mechanical damage

Loose or incompatible coatings may require removal before recoating.

Removing Salt Contamination

Street lighting columns exposed to road spray or coastal conditions may accumulate soluble salts.

If these remain beneath a new coating, they can contribute to premature coating failure.

Where required, soluble salt contamination should be assessed using an appropriate test method.

Salt levels should be reduced to the limits specified for the coating system before application.

Coating Application Methods for Street Lighting Columns

Protective coatings may be applied using different methods depending on the product, component design and working environment.

Common methods include:

  • Brush application

  • Roller application

  • Conventional spray

  • Airless spray

  • Air-assisted spray

Not every coating is suitable for every method.

The correct application procedure should follow the manufacturer's technical guidance.

Spray Application for Column Manufacturers

Spray application may be suitable for manufacturers coating large quantities of fabricated columns.

Important considerations include:

  • Coating viscosity

  • Spray equipment

  • Mixing ratios

  • Pot life

  • Application temperature

  • Film thickness

  • Overspray control

  • Ventilation

The selected process should be appropriate for the coating system and production requirements.

Dry Film Thickness & Coating Inspection

Dry film thickness is an important consideration in many corrosion protection specifications.

Insufficient coating thickness can compromise protection, while excessive thickness can create problems with certain products.

Coating Quality Control

Depending on the specification, inspection may include:

  • Surface preparation checks

  • Environmental condition monitoring

  • Wet film thickness measurements

  • Dry film thickness measurements

  • Visual inspection

  • Adhesion testing where required

Acceptance criteria should be established in the project specification.

Protecting Edges, Welds & Difficult Areas

Edges, welds and difficult-to-access areas can be vulnerable to insufficient coating coverage.

Where specified, stripe coating may be used to provide additional protection before applying the main coating system.

Sharp edges, weld spatter and other fabrication defects may also require attention before coating.

Street Lighting Column Maintenance & Refurbishment

Existing lighting columns may require maintenance as protective coatings deteriorate over time.

Common signs of coating deterioration include:

  • Visible corrosion

  • Blistering

  • Flaking

  • Cracking

  • Loss of adhesion

  • Exposed metal

  • Mechanical damage

  • Significant weathering

The appropriate maintenance approach depends on the condition of the existing coating and the required performance.

Recoating Existing Lighting Columns

Some existing columns may be suitable for recoating.

A typical refurbishment process may involve:

  1. Inspecting the existing coating and substrate

  2. Assessing corrosion and surface damage

  3. Cleaning the surface

  4. Removing loose or failing coatings

  5. Preparing exposed metal

  6. Applying a compatible protective coating system

Where corrosion or damage raises concerns about structural integrity, the column should be assessed by a suitably qualified professional before refurbishment.

A protective coating cannot restore lost structural strength.

ISO 12944 & Street Lighting Column Coatings

ISO 12944 is a series of standards covering the corrosion protection of steel structures using protective paint systems.

It provides guidance on environmental classification, coating selection and related requirements.

For street lighting infrastructure, the relevant coating specification may consider:
