Modern aluminium fencing systems: slat fences, alloys and finishes
A modern fencing system is a modular, powder-coated aluminium fence that provides privacy and security without the maintenance of timber or untreated steel. ULAMEX manufactures its fencing from aluminium alloy EN AW-6063 T6, powder-coated to a minimum 60 micron polyester finish, with horizontal slat, vertical slat and palisade designs, plus a steel alternative in the same colours. Every system assembles modularly, with no welding on site. This guide covers the styles, the alloy and finish, the colours, installation and how to specify a system.
What a modern fencing system is
A modern fence is a modular assembly of extruded aluminium profiles: posts, horizontal or vertical slats, and cross-rails, fixed together with bracket clips and self-drilling screws. There is no welding and no special tooling required on site. The result is a clean, contemporary boundary that defines a property while giving privacy, wind protection and security, and that stays maintenance-free for decades because the aluminium does not rust and the powder coating does not fade.
Fence styles
The system covers the full range of contemporary fence designs, all built on the same modular post-and-rail principle.
| Style | Character |
|---|---|
| Horizontal slat (louvered) | The most popular style; clean lines with privacy set by slat spacing |
| Vertical slat | Vertical lamellae for a different architectural line |
| Palisade | Spaced vertical bars for a lighter, secure boundary |
| Mixed orientation | Combined horizontal and vertical panels for feature sections |
Material and finish
The fencing is manufactured primarily from aluminium alloy EN AW-6063 T6, the industry-standard alloy for architectural and fencing extrusions, chosen for its corrosion resistance, formability and clean anodised or powder-coated surface. For the full alloy detail see our guide to EN AW aluminium alloys, and for the profile detail see aluminium profiles.
Every aluminium component is powder-coated to a minimum 60 micron polyester finish, which gives UV stability, weather resistance and a maintenance-free surface for 20 years or more. For projects that need extra rigidity, ULAMEX also supplies powder-coated steel fence panels in S235JR, which share the same colour palette and mounting system as the aluminium line.
RAL colours
Both the aluminium and steel lines use the same RAL palette, so a fence, gate and posts read as one system. Anthracite RAL 7016 dominates the European market for its neutral, timeless appearance.
| RAL | Colour |
|---|---|
| RAL 7016 | Anthracite grey (the most popular choice) |
| RAL 9005 | Jet black |
| RAL 7035 | Light grey |
| RAL 9006 | White aluminium (silver) |
For wholesale orders, any RAL colour can be produced on request, and the colour is confirmed on the order line and dispatch note.
System components
ULAMEX supplies everything needed for a complete installation, colour-matched and from stock: system posts, horizontal or vertical slats, cross-rails, post caps, mounting brackets, self-drilling screws, base plates and gate hardware. For large projects, the technical team prepares cut lists and quantity calculations on request.
Installation
The system is designed for modular self-assembly. Posts are set in concrete foundations or bolted to an existing wall with base plates. Slats and rails fix to the posts with bracket clips and self-drilling screws, so there is no welding and no specialist tooling on site. Detailed mounting instructions are available on request, and the technical team can advise on post spacing, panel dimensions and wind-load considerations for larger projects.
Wind load and post spacing
The wind resistance of a fence depends on slat spacing, post dimensions and foundation depth. Horizontal slat fences with gaps between the lamellae allow partial airflow, which reduces wind load compared with a solid panel. For exposed locations, ULAMEX recommends 100 x 100 mm posts with concrete foundations at a maximum spacing of 2,000 mm, and the technical team can advise on system selection for a specific wind-load zone.
Aluminium versus steel fencing
Both material lines are powder-coated and share the same colours and mounting system. Aluminium fences are lighter, fully corrosion-resistant and maintenance-free, which makes them the preferred choice for residential and architectural work. Steel fences are heavier and more rigid, giving greater mechanical strength for security-critical or high-wind installations; for galvanised steel fencing and panels see our guide to galvanised steel and DX51D and the galvanised fences range.
Applications
Modern fencing suits several sectors. Residential work covers front-yard fences, garden boundaries and terrace privacy screens, where horizontal slat designs dominate contemporary architecture. Commercial perimeters serve offices, hotels, restaurants and retail parks that want a premium appearance without maintenance. Public and institutional projects, schools, parks, healthcare and municipal buildings, need to meet wind-load requirements while staying open and contemporary. Industrial and security sites use the steel-based system for extra rigidity.

Frequently asked questions
What is a modern fencing system?
A modern fencing system is a modular, powder-coated aluminium fence built from posts, slats and rails that assemble with bracket clips and self-drilling screws, without welding. It provides privacy, wind protection and security with a clean contemporary appearance and no maintenance.
What alloy are aluminium fences made of?
ULAMEX aluminium fences are made from EN AW-6063 T6, the industry-standard alloy for architectural and fencing extrusions, chosen for its corrosion resistance, formability and clean powder-coated surface.
What RAL colours are available?
The standard palette is RAL 7016 (anthracite grey, the most popular), RAL 9005 (jet black), RAL 7035 (light grey) and RAL 9006 (white aluminium). For wholesale orders, any RAL colour can be produced on request.
Do aluminium fences need maintenance?
No. Powder-coated aluminium does not rust, repaint or rot. A polyester powder coating of 60 microns or more gives UV resistance and colour stability for 20 years or more; periodic cleaning with water is enough to keep the original appearance.
How are the fences installed?
By modular self-assembly. Posts are set in concrete foundations or bolted to a wall with base plates, and slats and rails fix to the posts with bracket clips and self-drilling screws. No welding or specialist tools are required, and mounting instructions are supplied on request.
Aluminium or steel fence: which is better?
Aluminium fences are lighter, fully corrosion-resistant and maintenance-free, ideal for residential and architectural work. Steel fences are heavier and more rigid for security-critical or high-wind sites. Both are powder-coated in the same RAL colours, and ULAMEX supplies both.
How much wind load can a fence take?
It depends on slat spacing, post dimensions and foundation depth. Horizontal slat fences with gaps allow partial airflow and reduce wind load. For exposed locations, ULAMEX recommends 100 x 100 mm posts with concrete foundations at a maximum spacing of 2,000 mm.
What components do you supply?
System posts, horizontal or vertical slats, cross-rails, post caps, mounting brackets, self-drilling screws, base plates and gate hardware, all colour-matched and from stock. Cut lists and quantity calculations are prepared on request for large projects.
