Why Outdoor Steel Products Need Corrosion Protection
Outdoor steel products are constantly exposed to harsh environmental conditions that can cause corrosion, surface damage, and long-term structural deterioration.
Without proper corrosion protection, steel can quickly begin to rust when exposed to:
- rain
- moisture
- frost
- road salt
- pollution
- changing temperatures
This is why corrosion protection is one of the most important considerations when selecting:
- security bollards
- height restriction barriers
- swing gates
- Armco barriers
- parking barriers
- perimeter fencing
- access control systems
At Aremco Barriers, we manufacture a wide range of steel barriers, bollards, and perimeter protection systems designed for long-term outdoor durability across commercial, industrial, highways, and public environments throughout the UK.
What Causes Steel To Corrode Outdoors?
Steel corrosion occurs when iron reacts with:
- oxygen
and - moisture
This chemical reaction creates rust, which gradually weakens the steel surface over time.
Outdoor environments accelerate this process due to continuous exposure to:
- rainfall
- humidity
- standing water
- road salt
- pollution
- industrial contaminants
- coastal air
Without protective finishes, corrosion can rapidly spread across exposed steel surfaces.
Why Is Corrosion Protection Important?
Corrosion protection helps:
- extend product lifespan
- reduce maintenance costs
- improve appearance
- maintain structural integrity
- prevent premature failure
- improve long-term value
For outdoor security and access control products, corrosion protection is critical because these products are often expected to remain in service for many years with minimal maintenance.
Which Outdoor Steel Products Require Corrosion Protection?
Virtually all outdoor steel products benefit from corrosion protection, including:
- bollards
- height barriers
- swing gates
- Armco crash barriers
- perimeter fencing
- parking barriers
- access control systems
- steel railings
- fabricated steelwork
This is especially important for products installed in:
- car parks
- industrial estates
- highways environments
- schools
- public spaces
- coastal locations
- logistics centres
What Are The Most Common Corrosion Protection Systems?
Several different finishing systems are commonly used to protect outdoor steel products.
Hot-Dip Galvanising
Hot-dip galvanising is one of the most widely used and effective corrosion protection systems.
The steel is immersed into molten zinc, creating a durable protective coating that helps prevent rust and environmental damage.
Benefits include:
- long service life
- low maintenance
- sacrificial zinc protection
- excellent outdoor durability
Powder Coating
Powder coating creates a durable coloured finish that improves:
- appearance
- UV resistance
- surface durability
- weather resistance
Powder coating is often applied over galvanised steel to create a duplex coating system.
Duplex Coating Systems
A duplex coating system combines:
- hot-dip galvanising
and - powder coating
to provide enhanced durability and corrosion protection.
This is one of the most effective finishing systems for outdoor steel security products.
What Happens If Steel Is Left Unprotected?
Unprotected steel exposed outdoors can develop:
- surface rust
- corrosion staining
- coating failure
- weakened structural sections
- reduced lifespan
- expensive repair requirements
In severe cases, long-term corrosion can compromise structural strength and safety.
Which Environments Are Most Aggressive For Steel Corrosion?
Corrosion can occur in any outdoor environment, but certain locations are more aggressive than others.
These include:
- coastal areas
- highways environments
- industrial sites
- chemical exposure zones
- areas exposed to road salt
- high moisture locations
Steel products installed in these environments often require higher levels of corrosion protection.
Why Is Galvanised Steel So Popular Outdoors?
Hot-dip galvanised steel remains one of the most popular outdoor steel finishes because it provides:
- excellent corrosion resistance
- strong long-term performance
- lower maintenance requirements
- reliable outdoor durability
- cost-effective protection
This is why galvanised steel is commonly used for:
- bollards
- barriers
- gates
- perimeter protection systems
- highways infrastructure
throughout the UK.
