Industrial Corrosion Protection for Steel & Metal

HERO SECTION

Industrial Corrosion Protection

Protecting Steel. Protecting Equipment. Protecting Performance.

Industrial environments can expose metal to conditions that accelerate corrosion.

Depending on the industry and operating environment, steel and metal may encounter:

• Moisture
• Humidity
• Rain
• Salt
• Chemicals
• Dust
• Pollution
• Temperature changes
• Water condensation
• Industrial contaminants
• Mechanical damage

When corrosion begins, simply applying another layer of paint may not solve the problem.

The correct approach starts with understanding the surface.

INSPECT → PREPARE → TREAT → PROTECT

WHAT IS INDUSTRIAL CORROSION?

Industrial corrosion is the deterioration of metals due to interaction with their surrounding environment.

For iron and steel, this commonly results in rust.

The process can begin when the metal is exposed to:

Over time, corrosion can affect the surface and, if left uncontrolled, may lead to progressive material loss.

WHY DOES INDUSTRIAL STEEL RUST?

Industrial steel rarely operates in a completely dry and clean environment.

A typical industrial surface may experience:

Industrial environments can make this more challenging because multiple factors may exist simultaneously.

MAJOR CAUSES OF INDUSTRIAL CORROSION

Moisture

Water is one of the most important contributors to atmospheric corrosion.

Sources include:

• Rain
• Condensation
• Washing
• Process water
• Leaks
• Humidity

High Humidity

High humidity can keep surfaces damp for longer.

This can increase corrosion risk when protective coatings are damaged or inadequate.

Salt

Salt-containing environments can accelerate corrosion.

This is particularly important in:

• Coastal industries
• Marine facilities
• Ports
• Chemical environments

Chemicals

Industrial facilities may expose metal to:

• Acids
• Alkalis
• Solvents
• Process chemicals
• Chemical vapours

Coating compatibility should always be verified for the actual chemical exposure.

Pollution

Industrial pollutants can interact with moisture and contribute to corrosive conditions.

Temperature Changes

Temperature fluctuations can cause:

• Condensation
• Thermal expansion
• Thermal cycling

These can affect both the metal and protective coating system.

Mechanical Damage

Impact, abrasion and scratches can break the protective coating.

Once the substrate becomes exposed:

WHERE DOES INDUSTRIAL CORROSION OCCUR?

Industrial corrosion can affect almost any exposed steel or iron surface.

Common examples include:

INDUSTRIAL STEEL STRUCTURES

Steel structures can represent a significant corrosion-protection requirement because of their:

• Large surface area
• Welded connections
• Bolted joints
• Edges
• Difficult-to-access areas
• Outdoor exposure

Areas to inspect include:

INDUSTRIAL MACHINERY CORROSION

Machinery may be exposed to:

• Water
• Oil
• Dust
• Chemicals
• Humidity
• Process contamination

Corrosion can develop on:

• Frames
• Supports
• Guards
• Covers
• Fabricated components
• External steel surfaces

The coating system should be selected according to the actual operating conditions.

PIPELINE CORROSION

Pipelines can experience different forms of corrosion depending on their:

• Material
• Location
• Contents
• Temperature
• External environment
• Coating
• Operating conditions

External atmospheric corrosion can be an important concern for exposed steel pipelines.

Before selecting a coating system, evaluate the actual service environment and technical specification.

INDUSTRIAL TANK CORROSION

Storage tanks may be exposed to:

• Rain
• Humidity
• Chemicals
• Salt
• Temperature changes

External surfaces can develop corrosion where protective coatings are damaged.

Important inspection points include:

• Shell
• Roof
• Welds
• Connections
• Supports
• Bottom sections

FACTORY STEEL CORROSION

Factory structures may look protected because they are inside a building.

But indoor steel can still corrode.

Possible causes include:

• High humidity
• Chemical vapours
• Condensation
• Process water
• Poor ventilation
• Chemical contamination

Therefore:

Indoor does not always mean corrosion-free.

WAREHOUSE STEEL CORROSION

Warehouse structures may experience:

• Roof leakage
• Condensation
• Humidity
• Water ingress
• Dust accumulation

Pay particular attention to areas around:

• Roofs
• Gutters
• Columns
• Joints
• Connections

AGRICULTURAL EQUIPMENT CORROSION

Agricultural machinery can encounter:

• Soil
• Water
• Fertilizers
• Chemicals
• Mud
• Humidity

These contaminants can remain on metal surfaces and contribute to corrosion.

Regular cleaning and coating maintenance are important.

INDUSTRIAL CORROSION IS NOT JUST A PAINT PROBLEM

This is a major positioning section for FERONIX.

A common approach is:

"The paint is damaged, so repaint it."

But the actual problem may be:

• Surface contamination
• Rust
• Poor preparation
• Salt
• Moisture
• Incompatible coating
• Insufficient coating thickness
• Incorrect application

Therefore:

Corrosion protection starts before painting.

FERONIX RUSTKLEEN

Rust Removal Solution

Industrial corrosion treatment often starts with surface preparation.

FERONIX RUSTKLEEN

is positioned as the REMOVE stage.

It may be suitable where chemical rust removal is appropriate.

The surface should first be assessed and prepared according to the product's technical requirements.

Key principle:

Remove unstable corrosion before protecting the metal.

FERONIX RUSTCON

Rust Converter Solution

Some surfaces may retain suitable residual rust after mechanical or chemical preparation.

FERONIX RUSTCON

is positioned as the TREAT stage.

It is designed for appropriate rust-conversion/treatment applications.

Important:

Rust conversion does not replace proper surface preparation.

Loose and unstable rust should not simply be left underneath a coating system.

FERONIX CERAMAX

Ceramic Metal Primer

For projects using a conventional primer-based coating system:

FERONIX CERAMAX

can serve as the primer stage where technically suitable.

Typical system:

This approach provides a defined primer stage between substrate preparation and the finishing protective coating.

FERONIX CORROX

is FERONIX's Direct-to-Metal anti-corrosive coating solution for suitable prepared metal applications.

Typical system:

One of the major advantages of a suitable DTM system is the ability to reduce the number of separate coating stages compared with conventional primer-plus-topcoat systems.

But:

DTM does not mean direct-to-loose-rust.

Appropriate surface preparation remains essential.

WHY SURFACE PREPARATION IS CRITICAL

Even a high-performance coating cannot compensate for a poorly prepared surface.

Common contaminants include:

• Rust
• Dust
• Oil
• Grease
• Salt
• Dirt
• Moisture
• Loose old coating

These can interfere with:

Therefore:

PREPARATION IS THE FOUNDATION OF PROTECTION.

INDUSTRIAL SURFACE PREPARATION

Depending on the condition and project requirements, preparation may include:

The appropriate preparation standard should be specified for the particular project.

HOW TO PREPARE INDUSTRIAL STEEL BEFORE COATING

Step 1 — Inspect

Determine the existing condition.

Step 2 — Remove contamination

Clean oil, grease, dirt, salt and other contaminants.

Step 3 — Remove loose coating

Unstable coating should not remain underneath the new system.

Step 4 — Remove unstable corrosion

Remove loose rust and scale.

Step 5 — Treat suitable residual rust

Use RUSTCON where appropriate.

Step 6 — Ensure the substrate is ready

Confirm the surface meets the coating requirements.

Step 7 — Apply the selected coating system.

INDUSTRIAL CORROSION HOTSPOTS

The following locations deserve additional attention:

WHY WELDS ARE IMPORTANT

Welded areas can create:

• Surface irregularities
• Crevices
• Sharp transitions
• Areas difficult to coat uniformly

Therefore, weld preparation and coating coverage are important components of an industrial corrosion-control program.

WHY EDGES MATTER

Coating thickness can be more difficult to maintain uniformly around sharp edges.

Poorly protected edges can become early corrosion locations.

Proper preparation and coating application should address these areas.

WHY WATER TRAPS ARE DANGEROUS

A steel surface that remains wet for a long period has greater corrosion risk than a surface that dries quickly.

Look for:

• Horizontal ledges
• Crevices
• Poor drainage
• Joint areas
• Bottom sections

Where possible, eliminate unnecessary water accumulation.

INDUSTRIAL COATING THICKNESS

Protective coating performance depends partly on achieving the specified dry film thickness.

Too little coating can reduce protection.

Too much coating may also create coating defects depending on the system.

Therefore:

Follow the specified DFT and FERONIX TDS.

Do not assume:

"More paint = more protection."

INDUSTRIAL CORROSION INSPECTION

A good inspection program should identify:

EARLY CORROSION VS ADVANCED CORROSION

Early Corrosion

• Small rust spots
• Surface staining
• Minor coating damage
• Localized rust

• Heavy rust
• Flaking
• Deep pitting
• Section loss
• Widespread coating failure

May require more extensive preparation and professional assessment.

Therefore:

Early intervention is usually better than delayed repair.

COST OF IGNORING INDUSTRIAL CORROSION

Corrosion can create costs beyond the paint itself.

Potential consequences include:

Therefore:

The cost of corrosion is often much higher than the cost of early protection.

CORROSION PROTECTION AND DOWNTIME

Industrial equipment cannot always be taken offline easily.

This makes coating-system selection important.

A suitable DTM system may simplify the coating process where technically appropriate.

However, the final system should always be selected according to:

• Exposure
• Performance requirement
• Application conditions
• Existing coating
• Substrate condition
• Project specification

INDUSTRIAL CORROSION DURING MONSOON

Monsoon can increase corrosion risk in exposed industrial environments because of:

• Rain
• Humidity
• Standing water
• Condensation
• Leaks

Industrial sites should inspect:

• Outdoor structures
• Equipment
• Pipelines
• Tanks
• Roofing supports
• Platforms
• Handrails

INDUSTRIAL CORROSION IN COASTAL AREAS

Coastal industrial environments can introduce an additional factor:

SALT

Therefore:

can create challenging corrosion conditions.

FROM CORRODED TO PROTECTED

WHY FERONIX?

FERONIX is designed around a simple principle:

Corrosion protection starts with understanding the surface.

Instead of treating every corrosion problem the same way, FERONIX provides solutions across different stages:

Need to treat suitable residual rust?

RUSTCON

Need a suitable Direct-to-Metal anti-corrosive coating?

CORROX

This creates a complete surface-protection conversation.

FERONIX IS MORE THAN PAINT

The FERONIX philosophy is:

Don't simply cover corrosion. Understand it. Prepare the surface. Treat where necessary. Protect the metal.

That positioning differentiates FERONIX from brands that communicate only:

"Anti-rust paint."

FERONIX becomes:

A SURFACE PROTECTION SOLUTION.
