Anti-Corrosion Coatings for Fabricated Steel

Corrosion protection is one of the most important considerations when coating fabricated steel.

Unprotected steel can deteriorate when exposed to moisture, oxygen and corrosive environmental conditions.

A suitable protective coating system can help reduce corrosion and extend the interval before major maintenance is required.

Choosing the Right Corrosion Protection System

The appropriate system depends on several factors:

• Environmental corrosivity

• Required durability

• Steel surface condition

• Surface preparation

• Application conditions

• Coating compatibility

• Expected maintenance requirements

For atmospheric corrosion protection, ISO 12944 provides a recognised framework for specifying protective paint systems for steel structures.

Different environments require different levels of protection.

For example, steel installed inside a dry manufacturing facility may require a different coating system from steel used in coastal infrastructure or exposed industrial environments.

Protective Coatings for C3, C4 & C5 Environments

Steel fabricators may be required to supply components for projects with specific corrosion protection requirements.

Under ISO 12944, atmospheric corrosivity categories include C3, C4 and C5.

• C3: Medium atmospheric corrosivity, which may apply to certain urban and industrial environments.

• C4: High atmospheric corrosivity, associated with more demanding industrial or coastal environments.

• C5: Very high atmospheric corrosivity, associated with particularly aggressive atmospheric conditions.

The appropriate classification should be determined by the project's actual exposure conditions.

A coating system should only be described as suitable for a particular category and durability range where the specification and supporting technical evidence justify that claim.

Industrial Primers for Steel Fabrication

Primers are an essential component of many protective coating systems.

They are commonly applied to prepared steel before intermediate coats or topcoats.

Depending on the product and specification, industrial primers can provide adhesion, corrosion protection and a suitable foundation for subsequent coatings.

Epoxy Primers for Steel

Epoxy primers are widely used in industrial protective coating systems.

Depending on the formulation, they may provide:

• Good adhesion to suitably prepared steel

• Corrosion protection

• Resistance to selected industrial contaminants

• Compatibility with specified protective topcoats

The required preparation standard and coating thickness should follow the manufacturer's technical data sheet.

Zinc-Rich Primers

Zinc-rich primers may be specified for certain corrosion protection systems.

These products are designed to provide corrosion protection through their zinc content when correctly formulated and applied.

Their performance depends on factors including surface preparation, dry film thickness and compatibility with subsequent coats.

Not every project requires a zinc-rich primer, and the appropriate system should be selected according to the specification.

Surface-Tolerant Primers

Some refurbishment and maintenance projects involve steel surfaces where full abrasive blasting is impractical.

Certain surface-tolerant primers may be suitable for appropriately prepared substrates under specified conditions.

However, surface tolerance does not mean that contamination, loose corrosion or failing coatings can be ignored.

The minimum preparation requirements of the selected product must still be achieved.

Protective Topcoats for Fabricated Steel

Protective topcoats provide the final exposed layer of many industrial coating systems.

Depending on the product, topcoats can contribute to weather resistance, durability, appearance and resistance to environmental exposure.

Polyurethane Topcoats

Polyurethane topcoats are commonly specified where colour retention, gloss retention and exterior durability are important.

Potential applications include:

• External fabricated steel

• Machinery frames

• Industrial equipment

• Structural steelwork

• Commercial infrastructure

Performance varies by formulation, so the selected system should be checked against the project requirements.

Epoxy Topcoats

Epoxy coatings may be used as exposed finishes in suitable industrial environments.

They can offer useful protective properties, although many conventional epoxy coatings are susceptible to chalking and colour change under prolonged UV exposure.

Where appearance and colour retention are important outdoors, a compatible UV-resistant topcoat may be required.

Coatings for Structural Steel Fabricators

Structural steel is used throughout construction, industrial buildings, warehouses and infrastructure projects.

Steel fabricators may be required to deliver components with specified corrosion protection systems already applied.

Suitable applications include:

• Beams and columns

• Structural frames

• Support structures

• Bracing

• Platforms

• Access structures

• Industrial building steelwork

Workshop-Applied Structural Steel Coatings

Applying protective coatings in a fabrication workshop can provide greater control over preparation and application conditions.

Where suitable, workshop coating can help manufacturers manage:

• Surface cleanliness

• Abrasive blasting

• Coating application

• Film thickness

• Drying and curing

• Inspection procedures

However, coated components may still require repairs after transport, handling, welding or installation.

The project specification should account for these activities.

Protective Coatings for Street Lighting Columns

Street lighting columns represent a valuable specialist application for steel fabricators and infrastructure manufacturers.

Columns may be exposed to moisture, atmospheric contamination, road spray and changing weather conditions throughout their service life.

Depending on the design and specification, protective coatings may be required for:

• Steel lighting columns

• Column bases

• Brackets

• Support structures

• Associated fabricated components

Corrosion Protection for Lighting Columns

Coating selection should consider:

• Substrate material

• Galvanised or ungalvanised steel

• Environmental exposure

• Surface preparation

• Required durability

• Existing protective treatments

• Project specifications

Where lighting columns are galvanised, additional coatings must be compatible with the zinc surface and any existing treatments.

Particular attention may also be required around column bases and areas exposed to standing moisture or road contamination.

Coatings for Telecommunications Infrastructure

Steel fabricators supplying telecommunications projects may require protective coating systems for external structures and equipment.

Suitable applications may include:

• Telecommunications masts

• 5G infrastructure supports

• Equipment frames

• Mounting brackets

• External cabinets

• Structural supports

These components may be exposed to changing weather conditions, moisture and atmospheric corrosion.

Protective Coatings for 5G Masts & Supports

Coating requirements depend on the structure's location, substrate and expected service environment.

For external steelwork, the specification should consider:

• Corrosion protection

• Environmental exposure

• Surface preparation

• Coating durability

• Maintenance accessibility

• Compatibility with existing treatments

A suitable coating system can help protect exposed metal components throughout their intended service environment.

Coatings for Machinery Frames & Equipment Manufacturers

Steel fabricators often manufacture frames, supports and housings for industrial machinery.

These components may require protective finishes before assembly or delivery.

Suitable applications include:

• Machinery frames

• Equipment bases

• Fabricated supports

• Machine guards

• Metal housings

• Industrial enclosures

Coating Requirements for Machinery Components

The correct system should reflect the operating conditions of the finished equipment.

Important considerations include:

• Indoor or outdoor use

• Exposure to oil and grease

• Mechanical wear

• Required appearance

• Application method

• Drying and curing time

Manufacturers producing similar components regularly may benefit from establishing a consistent coating specification.

Coatings for Galvanised Steel Fabrications

Galvanised steel is commonly used for external fabricated components because of the corrosion protection provided by its zinc coating.

In some applications, an additional paint system may be specified to provide decorative or supplementary protection.

This is commonly referred to as a duplex coating system.

Preparing Galvanised Steel for Painting

Successful coating of galvanised steel depends on suitable surface preparation and product compatibility.

Before coating, assess the surface for:

• Oil and grease

• Dirt and contamination

• Zinc corrosion products

• Surface treatments

• Moisture

• Existing coatings

Preparation methods may include cleaning and suitable mechanical or chemical treatment, depending on the selected system.

The manufacturer's requirements should always be followed.

Coatings for Aluminium Fabrications

Some fabrication businesses also manufacture aluminium components requiring protective finishes.

Potential applications include:

• Equipment housings

• Industrial panels

• Fabricated frames

• Machinery components

• External enclosures

Aluminium requires suitable surface preparation and compatible primers.

The correct coating system depends on the alloy, surface condition and operating environment.

Surface Preparation for Steel Fabricators

Surface preparation is one of the most important factors affecting protective coating performance.

Even a high-performance coating may fail prematurely if applied to contaminated or poorly prepared steel.

Before coating, the substrate should be assessed for:

• Rust and corrosion

• Oil and grease

• Dirt and dust

• Mill scale

• Loose coatings

• Soluble salts

• Surface defects

Abrasive Blasting

Abrasive blasting is commonly used to prepare fabricated steel for protective coating systems.

Depending on the specification, blasting can remove rust, mill scale and other surface material while creating a suitable surface profile.

The required cleanliness grade and profile should be established before work begins.

Mechanical Surface Preparation

Mechanical preparation may be appropriate for certain fabrication or maintenance applications.

Methods can include:

• Grinding

• Power-tool cleaning

• Mechanical abrasion

• Localised preparation

The selected method must achieve the requirements of the coating specification.

Removing Soluble Salt Contamination

Soluble salts can contribute to premature coating failure when trapped beneath a protective coating.

Steel exposed to marine environments, road contamination or certain industrial conditions may require soluble salt assessment.

Where testing is required, appropriate methods such as the Bresle method may be used to assess surface contamination.

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

Removing visible rust alone does not necessarily remove soluble salts.

Coating Application for Steel Fabricators

Steel fabricators may apply protective coatings using different methods depending on component size, production requirements and the selected product.

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 data sheet.

Spray Coatings for Fabrication Workshops

Spray application can be particularly useful for businesses coating multiple fabricated components.

Important considerations include:

• Coating viscosity

• Spray equipment

• Mixing ratios

• Pot life

• Application temperature

• Required film thickness

• Overspray control

• Ventilation

The appropriate equipment and procedures should be selected according to the product and working environment.

Dry Film Thickness & Coating Inspection

Dry film thickness is an important part of many protective coating specifications.

Applying insufficient coating thickness can compromise protection, while excessive thickness can also cause problems with certain products.

Measuring Coating Thickness

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

The acceptance criteria should be established in the project specification.

Stripe Coating Edges & Welds

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

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

Fabrication quality also matters. Sharp edges, weld spatter and surface defects may require attention before coating.

Coatings for Repeat Production & OEM Fabrication

Fabrication businesses producing similar components regularly may require a coating system that supports consistent application and finish quality.

For repeated production, important considerations include:

• Product availability

• Colour consistency

• Application efficiency

• Mixing requirements

• Drying and curing times
