Galvanized Fence Posts — Rectangular Tube Posts for Panel Fence Systems
Galvanized fence posts from ULAMEX form the vertical load-bearing structure of every welded mesh fence installation. These rectangular hollow section posts — available in 60×40 mm (standard) and 80×60 mm (heavy-duty) profiles — are engineered to support 3D fence panels and 2D fence panels at the standard 2,500 mm post spacing used throughout European panel fence systems. Hot-dip galvanized per EN ISO 1461, these posts deliver decades of maintenance-free performance in all outdoor environments.
As a specialist steel fence wholesale supplier with over 38 years of European market experience, ULAMEX maintains comprehensive stock of fence post sizes covering every standard panel height, in both mounting configurations (base plate and straight/concrete-in), ready for immediate dispatch. Whether you are equipping a residential boundary fence or a multi-kilometre industrial perimeter, our B2B pricing and logistics ensure your project receives the right posts, on time, at competitive wholesale rates.
Post Profiles: 60×40 mm and 80×60 mm
The post profile selection depends on the fence panel type, panel height, wind exposure and security requirements of the installation:
60×40 mm Posts (Standard):
- The standard post for 3D fence panels up to 2,030 mm height with wire diameters of 4 mm and 5 mm
- Wall thickness: 1.5 mm (standard) or 2.0 mm (reinforced)
- Suitable for residential, commercial and standard industrial applications in sheltered to moderately exposed locations
- Compatible with all standard mounting clamps
80×60 mm Posts (Heavy-Duty):
- Recommended for 2D panels (especially 8/6/8 configuration), 3D panels with 6 mm wire, and all panels above 2,030 mm height
- Wall thickness: 2.0 mm
- Required for exposed/high-wind locations, elevated security perimeters and fence runs supporting barbed wire or razor wire extensions
- Provides approximately 70% greater bending resistance than 60×40 mm posts of the same wall thickness
Post Length Selection Guide
Fence post length is calculated as the panel height plus the required embedment or foundation depth. For concreted posts, the standard embedment depth is 500–600 mm below ground level, providing adequate lateral restraint for wind loads and impact forces. For base plate posts, the post length equals the panel height plus the bracket clearance (typically 50–100 mm above foundation level).

Mounting Options
ULAMEX galvanized fence posts are available in two mounting configurations to suit every foundation type:
Straight Posts for Concreting
The most common installation method. The lower portion of the post (500–600 mm) is embedded directly into a concrete foundation, typically using C20/25 grade concrete in a hole of approximately 300×300 mm cross-section. This method provides excellent lateral stability and is the standard approach for new fence installations on unpaved ground.
Advantages: Maximum stability, lowest cost, no additional foundation work beyond post holes. Suitable for all soil types with appropriate hole depth.
Base Plate Posts (Bolt-Down)
Posts with a welded steel base plate (typically 150×150 mm or 200×200 mm) are designed for mounting onto existing concrete foundations, kerbs, retaining walls or other solid substrates using anchor bolts or chemical anchors. The base plate is factory-welded and fully galvanized as part of the post assembly.
Advantages: No excavation required, suitable for existing hard surfaces, allows precise post positioning on pre-cast foundations, enables future removal/relocation without breaking concrete.
Surface Treatment
All fence posts undergo hot-dip galvanizing per EN ISO 1461 as standard. The galvanizing process immerses the complete post — including weld zones, base plates and internal surfaces — in molten zinc at approximately 450°C. The resulting multi-layer zinc-iron alloy coating provides:
- 40–80 µm zinc thickness on external surfaces (per ISO 1461, Table 3, for material thickness ≥1.5 mm)
- Cathodic (sacrificial) protection at cut edges, drill holes and minor surface damage
- 30–50+ years maintenance-free service life in corrosivity categories C2–C3 (EN ISO 9223)
- Internal coating — the hollow section interior is also galvanized, preventing inside-out corrosion that destroys unprotected posts within 5–10 years
For colour-matched installations, the duplex system (galvanized + polyester powder coating) is available in:
- RAL 6005 — Moss Green
- RAL 7016 — Anthracite Grey
- RAL 9005 — Jet Black
- Other RAL colours on request for wholesale orders
Post Caps
Every ULAMEX fence post is supplied with a plastic post cap (colour-matched to the post finish) that presses into the open top of the rectangular tube. Post caps serve three essential functions:
- Weather protection: Prevent rainwater from collecting inside the hollow post, which would accelerate corrosion from the inside out — even through the internal galvanized coating over time
- Safety: Cover the sharp metal edges at the top of the post, reducing injury risk during installation and ongoing use
- Aesthetics: Provide a clean, finished appearance to the fence line
Applications
Galvanized fence posts are the structural backbone of every panel fence galvanized system. Wherever fence panels are installed, posts are required at 2,500 mm intervals plus at every corner, end point and gate position. Typical applications include:
- Industrial and commercial perimeter fencing — factories, warehouses, logistics centres, office parks
- Residential property boundaries — housing developments, private gardens, apartment complexes
- Agricultural enclosures — farm perimeters, livestock areas, crop protection zones
- Sports facilities — football pitches, tennis courts, athletics tracks, playgrounds
- Infrastructure perimeters — solar farms, substations, water treatment plants, telecommunications sites
- Public spaces — schools, hospitals, parks, municipal boundaries
Corner, End and Gate Posts
In addition to standard intermediate posts (supporting panels on both sides), ULAMEX supplies:
- End posts: Posts at the start or end of a fence run, supporting a panel on one side only
- Corner posts: Posts at 90° direction changes, supporting panels on two perpendicular sides. Corner posts typically use the 80×60 mm profile for additional strength, regardless of panel specification
- Gate posts: Reinforced posts (typically 80×60 mm or 100×100 mm) at gate and wicket positions, bearing the additional weight and dynamic loads of the gate leaf. Supplied with hinge brackets and latch provisions as specified

Frequently Asked Questions
What fence post size do I need?
For standard 3D panels with 4 mm or 5 mm wire up to 2,030 mm height: use 60×40 mm posts. For 2D panels, 6 mm wire 3D panels, heights above 2,030 mm, or exposed locations: use 80×60 mm posts. When in doubt, the heavier post is always the safer choice.
Should I concrete posts or use base plates?
Concreting provides the strongest installation and is preferred for all new-build fences on soil or gravel. Base plate mounting is used when attaching to existing concrete foundations, retaining walls, or when future relocatability is required.
How deep should posts be concreted?
Standard embedment depth is 500–600 mm for posts up to 2,600 mm total length. For the tallest posts (3,000 mm for 2,430 mm panels), embedment of 600 mm minimum is recommended. In very soft soils or high-wind areas, increase embedment by 100–200 mm.
How many posts do I need per 100 metres of fence?
At the standard 2,500 mm post spacing: 41 posts per 100 metres (including start and end posts). Add posts for every corner, gate position, and wicket position. For a precise count, provide your fence layout and ULAMEX will calculate the exact requirement.
