Description
The Aluminium 50mm Plain Post is designed for fabricators and installers who want to manufacture their own stand-alone, surface-mounted aluminium posts for pool fencing, privacy screens and other compatible fencing applications.
Rather than purchasing a post with a permanently welded base plate, the plain aluminium extrusion can be cut to the required height and combined with the compatible BP100 screw-on aluminium base plate to create a custom-height flanged post.
An optional CP100 aluminium cover plate can then be fitted over the base to conceal the mounting plate and fixings, providing a clean and professional finished appearance.
This system is ideal for custom fabrication, allowing stand-alone posts to be manufactured to suit the exact height and requirements of the installation.
🔧 Make Your Own Flanged Post
The primary purpose of this extrusion is to allow you to manufacture your own stand-alone flanged aluminium post.
Simply:
- Cut the aluminium post to the required height
- Fit the compatible BP100 screw-on base plate to the bottom of the post
- Secure the base plate to the post using suitable screws
- Anchor the completed post to the supporting concrete or structure
- Fit the optional CP100 cover plate for a clean finished appearance
This provides a simple and flexible alternative to purchasing pre-manufactured posts in fixed heights.
📏 Cut to Your Required Height
Because the post starts as a plain aluminium extrusion, you can determine the finished height yourself.
This makes it particularly useful for custom projects where standard pre-manufactured post heights are unsuitable.
Typical applications include:
- Custom-height pool fence posts
- Privacy screen posts
- Aluminium slat screen posts
- Stand-alone fencing posts
- End posts
- Corner posts
- Custom fabricated barriers
- Architectural screening
🔩 Compatible BP100 Screw-On Base Plate
The AE413 plain post is designed to work with the compatible BP100 aluminium screw-on base plate.
The BP100 creates the flange required to convert the plain extrusion into a surface-mounted stand-alone post.
The supplier specifies the BP100 as a:
- Aluminium screw-on base plate
- Suitable for plain posts
- Suitable for slat posts
- Suitable for glazed posts
- 100 × 100mm
- 10mm thick
The BP100 base plate is available separately.
🔨 Base Plate Fixing
The BP100 base plate is mechanically fastened to the bottom of the aluminium post.
The manufacturer’s flanged-post configuration recommends:
12g × 1¾” screws for securing the base plate to the post.
The appropriate fasteners and installation method should always be confirmed for the particular application and loads imposed on the completed post.
🧱 Surface-Mounted Post System
Once the BP100 has been fitted, the completed post can be installed onto a suitable supporting surface.
This creates a stand-alone surface-mounted post without requiring the aluminium extrusion itself to be embedded into the ground.
Typical mounting surfaces may include suitable:
- Concrete slabs
- Concrete footings
- Masonry structures
- Engineered structural substrates
Appropriate anchors must be selected according to the supporting structure and loads imposed on the post.
◻️ Optional CP100 Cover Plate
For a cleaner finished appearance, the completed post can be combined with the optional CP100 pressed aluminium cover plate.
The CP100 sits over the BP100 base plate to help conceal the mounting plate and structural fixings.
This provides a much neater finished appearance, particularly where the post base remains visible.
The CP100 cover plate is available separately.
🧢 Compatible 50mm Post Caps
The 50mm post can also be finished with a compatible post cap.
The manufacturer’s range includes the PTCF50 cast aluminium flat post cap specifically listed as suitable for the AE413 plain post.
A post cap provides a clean finished appearance while closing the open top of the extrusion.
🏊 Ideal for Custom Pool Fencing Posts
The manufacturer specifically identifies the AE413 plain post as suitable for making custom flanged posts for pool fencing.
This allows installers and fabricators to manufacture posts at the required height rather than relying entirely on standard pre-made flanged post sizes.
Where used as part of a swimming pool barrier, the completed post and entire fencing system must be installed in accordance with the applicable Australian Standards and local pool-barrier requirements.
🪟 Ideal for Privacy Screens
The manufacturer also specifically recommends the plain post for creating flanged posts for privacy-screen installations.
This makes it particularly useful when fabricating:
- Aluminium slat screens
- Privacy screens
- Decorative screens
- Boundary screens
- Courtyard screens
- Equipment enclosures
- Architectural screening
The plain extrusion gives the fabricator freedom to position rails, slats and brackets according to the particular screen design.
🛠️ Fabricator-Friendly Design
Because the post is supplied plain, there are no factory-positioned rail openings restricting how the extrusion can be used.
The post can be cut, drilled and prepared to suit the particular project.
This is particularly useful for fabricators producing custom fencing and screening systems where every installation may require different post heights or component positions.
🪶 Lightweight Aluminium Construction
The aluminium construction makes the post relatively lightweight and easy to handle during fabrication and installation.
Aluminium is also naturally corrosion resistant, making it particularly well suited to permanent outdoor fencing and screening applications.
🌦️ Suitable for Outdoor Applications
Unlike conventional untreated steel, aluminium does not develop red rust when exposed to normal outdoor conditions.
This makes the post an excellent choice for external installations including:
- Pool areas
- Gardens
- Courtyards
- Residential fencing
- Privacy screening
- Architectural screens
The actual durability of the finished system will also depend on the selected surface finish and environmental conditions.
🎨 Multiple Finish Options
Depending on available stock, the AE413 extrusion is manufactured in a range of mill and finished options.
Select the required length and finish from the available product options above.
This allows the post to be coordinated with the surrounding fencing, gate or privacy-screen system.
🧩 Build the Complete Post
A typical stand-alone flanged post can be assembled using:
- 1 × AE413 50mm Plain Aluminium Post
- 1 × BP100 100 × 100 × 10mm Aluminium Screw-On Base Plate
- 1 × CP100 Pressed Aluminium Cover Plate – optional
- 1 × Compatible 50mm Post Cap – optional
- Suitable base-to-post screws
- Suitable structural anchors for mounting the completed post
This modular arrangement allows the post to be manufactured at the required height and configured specifically for the project.

Compatibility
For creating a complete stand-alone flanged post, the AE413 can be combined with:
- BP100 Aluminium Screw-On Base Plate
- CP100 Pressed Aluminium Cover Plate
- PTCF50 Flat Aluminium Post Cap
- Suitable structural anchors
- Suitable base-to-post screws
The BP100 is specifically listed by the manufacturer for slat posts, plain posts and glazed posts.
⚠️ Please Note
This product is the plain aluminium post extrusion only unless otherwise stated in the product options.
BP100 base plates, CP100 cover plates, post caps, structural anchors and fixing screws should be purchased separately where required.
The post must be cut to the required finished height before assembly.
The manufacturer’s flanged-post configuration recommends 12g × 1¾” screws for securing the base plate to the post.
Structural anchors used to secure the BP100 to the supporting surface must be selected according to the substrate, post height, fencing system and loads imposed on the completed installation.
Where the post forms part of a swimming pool barrier, the complete post, base plate, anchors, fencing and gate system must comply with all applicable Australian Standards and local pool-safety requirements.
Do not assume that simply combining the AE413 and BP100 automatically creates a compliant structural post for every application. Post height, spacing, wind loads, barrier type, fixing substrate and anchoring method must all be suitable for the intended installation.
