A coastal industrial processing site in Portugal required a perimeter fence around production zones, utility areas, service roads, storage sections, and controlled entrances.
The project needed a high-security welded mesh system, but corrosion protection was equally important because the fence would remain outdoors in a coastal environment.
For this project, BDFENCE supplied a hot-dip galvanized 358 Security Fence system with welded anti-climb panels, galvanized steel posts, security fixings, pedestrian gates, vehicle gates, and installation accessories.
The perimeter was designed around two priorities: security and long-term outdoor protection.

The Coastal Location Changed the Fence Specification
The fence would not operate in a dry inland environment.
The industrial site was exposed to coastal air, moisture, changing weather, and long-term outdoor conditions.
Therefore, the project team had to consider corrosion protection before finalizing the complete fence package.
The main concerns included:
- Salt-bearing coastal air
- Outdoor moisture
- Exposed steel connections
- Gate hardware
- Post bases
- Long-term surface condition
For this reason, the finish was treated as part of the technical specification rather than only a visual choice.
Why 358 Security Fence Was Selected
The site required a perimeter with stronger anti-climb characteristics than a general-purpose welded mesh fence.
358 Fence uses a narrow rectangular opening, commonly around 76.2 × 12.7 mm.
That mesh geometry provides limited conventional hand and foot holds while still allowing visibility through the perimeter.
For the industrial site, this supported:
- Controlled access
- Perimeter observation
- Security monitoring
- Clear separation of restricted areas
Why Hot-Dip Galvanizing Was Important
The project needed more than a secure mesh geometry.
The steel also needed a suitable corrosion-protection system for the coastal environment.
Hot-dip galvanizing applies a zinc-based protective layer to fabricated steel components.
For this project, that approach helped provide a practical base protection system for the exposed steel perimeter.
The finish was not limited to the mesh panels alone.
The Complete Fence Needed the Same Protection Logic
One common mistake in coastal fence projects is protecting the panels well while overlooking other exposed steel parts.
A perimeter can age unevenly if the panels, posts, gates, and fittings use very different protection levels.
Therefore, the project review considered:
- 358 welded mesh panels
- Line posts
- Corner and end posts
- Gate posts
- Pedestrian gate frames
- Vehicle gate frames
- Security fixing components
This helped create a more consistent protection strategy across the complete perimeter.
Post Bases Needed Extra Attention
The lower section of a steel post can face different conditions from the upper fence panel.
Post bases may be exposed to:
- Ground moisture
- Concrete contact
- Standing water
- Road splash
- Cleaning activity
For this reason, the post installation method and corrosion protection needed to be considered together.
A well-protected panel does not compensate for a poorly detailed post base.
Security Fixings Were Part of the Coastal Design
358 Fence relies on a secure connection between panel and post.
The project therefore used compatible fixing components according to the approved fence system.
These could include:
- Steel fixing bars
- Security clamps
- Anti-tamper bolts
- Security nuts
- Washers
- Post caps
The finish and material compatibility of these components also mattered because they remained exposed to the same environment as the main fence.
Industrial Access Points Needed Stronger Gate Systems
The facility required separate access for staff, maintenance teams, and vehicles.
Therefore, the perimeter included both pedestrian and vehicle gates.
Gate areas were important because they combined:
- Moving frames
- Heavy posts
- Hinges
- Locks
- Repeated daily use
- Coastal exposure
For this reason, the gate system was treated as part of the security perimeter rather than as an accessory.
What BDFENCE Supplied
| Component | Project Function |
|---|---|
| 358 Welded Mesh Panels | Main anti-climb perimeter barrier |
| Galvanized Steel Posts | Support the welded fence panels |
| Corner and End Posts | Support perimeter changes and terminations |
| Security Fixings | Connect panels to posts |
| Anti-Tamper Fasteners | Secure the connection system |
| Pedestrian Gates | Controlled personnel access |
| Vehicle Gates | Service and maintenance access |
Panel Consistency Was Important on Long Industrial Runs
The site included long fence sections around operational areas.
Small production differences can become noticeable when many panels are installed in sequence.
Therefore, BDFENCE checked:
- Panel height
- Panel width
- Mesh opening
- Wire diameter
- Panel flatness
- Weld condition
- Overall geometry
Consistent panels helped the installation team maintain a more uniform fence line.
The Galvanized Surface Was Checked Before Packing
The surface treatment was one of the key project requirements.
Therefore, visible galvanized condition was reviewed together with the normal dimensional checks.
| Component | Inspection Focus |
|---|---|
| 358 Panels | Mesh, dimensions, welds and galvanized condition |
| Steel Posts | Section size, wall thickness, length and surface condition |
| Security Fixings | Type, fit and quantity |
| Pedestrian Gates | Frame dimensions, alignment and finish |
| Vehicle Gates | Frame structure, post compatibility and finish |
| Accessories | Type and quantity |
Packaging Needed to Protect the Galvanized Components
A corrosion-protected fence still needs careful transport handling.
Panels, posts, gates, and smaller fittings can rub against each other during loading and shipping if they are not secured correctly.
BDFENCE therefore organized the shipment by component type.
The 358 panels were stacked and secured, posts were bundled separately, and security fittings were packed in identified groups.
Gate components also received separate packing and identification.
Installation Followed the Industrial Site Layout
Before panel installation began, the contractor confirmed:
- Fence route
- Corner positions
- End positions
- Pedestrian entrances
- Vehicle entrances
- Service road crossings
The steel posts were then installed according to the approved perimeter layout.
Accurate post positioning was important because 358 Fence uses rigid welded panels rather than flexible woven mesh.
Typical Installation Sequence
- Set out the industrial perimeter
- Confirm corners and access points
- Mark steel post positions
- Install the galvanized posts
- Complete the required foundations
- Position the 358 welded panels
- Secure panels with the specified security fixing system
- Install pedestrian gates
- Install vehicle gates
- Check fence alignment, connections and surface condition
What the Completed Perimeter Delivered
| Project Requirement | Fence Response |
|---|---|
| Anti-Climb Perimeter | Narrow 358 welded mesh |
| Coastal Outdoor Exposure | Hot-dip galvanized steel system |
| Security Visibility | Open welded mesh construction |
| Personnel Access | Matching pedestrian gates |
| Vehicle Access | Industrial vehicle gates |
| System Compatibility | Panels, posts, fixings and gates supplied together |
The completed fence gave the industrial site a more controlled perimeter while keeping the system practical for long-term outdoor exposure.
What Coastal Industrial Buyers Should Check in a Quote
Two quotations can both say “hot-dip galvanized 358 Fence” while representing different complete systems.
Buyers should compare:
- Actual wire diameter
- Mesh opening
- Panel dimensions
- Post size
- Post wall thickness
- Post length
- Fixing system
- Gate specification
- Surface treatment requirement
- Treatment of exposed steel fittings
This is especially important in coastal projects because weak protection on posts, gates, or fittings can reduce the value of a well-protected panel.
Why the Lowest Panel Price May Not Be the Lowest Project Cost
A coastal industrial perimeter should be evaluated as a complete system.
If a lower quotation uses lighter posts, fewer security fixings, or lower-protection gate components, the panel price alone may be misleading.
A more useful comparison looks at the complete perimeter package and the expected outdoor environment.

Project Takeaway
For this coastal industrial site in Portugal, the fence specification could not stop at “358 mesh.”
The perimeter needed both anti-climb performance and a corrosion-protection strategy suited to long-term outdoor exposure.
The most important result came from treating the 358 panels, steel posts, security fixings, gates, and surface treatment as one complete system.
That approach reduced the risk of protecting the visible panels well while leaving weaker components elsewhere in the perimeter.

FAQ
Why use hot-dip galvanized 358 Fence in a coastal industrial site?
The 358 mesh provides anti-climb characteristics, while hot-dip galvanizing helps protect the steel components against long-term outdoor corrosion. The final finish should match the actual coastal environment and project specification.
Is galvanized 358 Fence suitable near the coast?
It can be suitable when the galvanizing system, posts, fixings, gates, and other exposed steel components meet the required corrosion-protection specification.
