Description
Base Plate Square 100mm – BPL100
The BPL100 Square Base Plate is designed for creating your own stand-alone, surface-mounted aluminium posts.
Measuring 100 × 100mm, the base plate is fitted to the bottom of a compatible plain aluminium post, converting the extrusion into a flanged post that can be anchored to a suitable concrete or structural surface.
It is an ideal companion to the Aluminium 50mm Plain Post, allowing fabricators and installers to cut their post to the required height and manufacture a custom stand-alone post without requiring a welded base plate.
This system is particularly useful for pool fencing, privacy screens, aluminium slat fencing and other custom fencing applications.
🔧 Make Your Own Stand-Alone Posts
The BPL100 provides a simple way to convert a compatible plain aluminium post into a surface-mounted flanged post.
A typical installation involves:
- Cut the aluminium post to the required height
- Position the BPL100 at the bottom of the post
- Mechanically secure the base plate to the post
- Anchor the completed post to a suitable structural surface
- Fit a compatible cover plate where required
This allows custom-height stand-alone posts to be manufactured as required for each project.
📐 100 × 100mm Square Base Plate
The BPL100 features a compact square footprint suitable for compatible 50mm aluminium post systems.
Base plate dimensions:
- Length: 100mm
- Width: 100mm
- Shape: Square
Its compact footprint provides a neat mounting solution without requiring an unnecessarily large flange around the bottom of the post.
🚧 Designed for 50mm Plain Posts
The BPL100 is the compatible base plate for the 50mm plain post system used to manufacture custom flanged posts.
This makes it ideal for creating:
- Stand-alone fence posts
- Pool fence posts
- Privacy screen posts
- Aluminium slat posts
- End posts
- Intermediate posts
- Custom fencing posts
- Architectural screen supports
🔩 Screw-On Base Plate
Rather than requiring the base plate to be welded to the aluminium extrusion, the BPL100 is mechanically fastened to the post.
This makes it particularly useful for installers and fabricators who want to manufacture custom posts without aluminium welding equipment.
It also allows standard lengths of plain post extrusion to be cut and converted into individual stand-alone posts as required.
🔨 Recommended Base-to-Post Screws
For the flanged-post configuration shown by the manufacturer, the recommended screws for securing the base plate to the post are:
- 12g × 1¾” screws
These screws secure the post extrusion to the base plate.
Structural anchors used to secure the completed post to the mounting surface are separate and must be selected according to the substrate and installation requirements.
🧱 Surface-Mounted Installation
Once fitted to the post, the BPL100 creates a flange that allows the completed post to be surface mounted.
Depending on the application, the completed assembly may be mounted onto a suitable:
- Concrete slab
- Concrete footing
- Masonry structure
- Engineered structural substrate
The correct structural anchors must be selected for the supporting material and loads imposed on the finished post.
🏊 Ideal for Pool Fencing
The BPL100 and compatible plain post can be used to manufacture custom stand-alone posts for suitable pool fencing installations.
This is particularly useful where a surface-mounted post is required rather than a post that is core drilled or embedded into the ground.
The post can be cut to the required height before the BPL100 is fitted.
Where used as part of a pool barrier, the complete installation must comply with applicable Australian Standards and local pool-safety requirements.
🪟 Perfect for Privacy Screens
The BPL100 is also ideal for creating stand-alone posts for aluminium privacy and screening systems.
Typical applications include:
- Aluminium slat screens
- Privacy screens
- Decorative screens
- Courtyard screens
- Boundary screens
- Equipment screens
- Architectural screening
The ability to manufacture posts at custom heights makes the system particularly useful for fabricated screening projects.
🛠️ No Aluminium Welding Required
One of the major advantages of the BPL100 system is that the base plate can be mechanically secured to the post.
This eliminates the need to weld a flange onto every individual post.
For installers working on-site or fabricators without aluminium welding equipment, this provides a convenient way of producing custom-height stand-alone posts.
✂️ Create Custom Post Heights
When combined with a compatible length of plain aluminium post, the BPL100 allows multiple custom posts to be fabricated from longer extrusion lengths.
Simply determine the required finished height, cut the extrusion and attach a BPL100 to each post.
This provides significantly greater flexibility than relying entirely on pre-manufactured flanged posts in predetermined heights.
◻️ Add a Cover Plate for a Clean Finish
A compatible square cover plate can be fitted over the BPL100 after the post has been installed.
The cover helps conceal the structural base plate and mounting anchors, providing a cleaner and more professional finished appearance.
This is particularly useful for visible residential installations such as:
- Pool fencing
- Front fencing
- Privacy screens
- Courtyard screens
- Architectural fencing
The compatible cover plate is available separately.
🪶 Aluminium Construction
The BPL100 is manufactured from aluminium, making it suitable for use with aluminium post and fencing systems.
Aluminium provides excellent natural corrosion resistance and is particularly well suited to permanent outdoor applications.
🌦️ Suitable for Outdoor Applications
The aluminium construction makes the BPL100 suitable for exposed fencing and screening installations.
Typical applications include:
- Residential fencing
- Pool areas
- Gardens
- Courtyards
- Privacy screens
- Aluminium fencing
- Architectural screening
The suitability of the complete installation will depend on the environmental conditions, selected fasteners and mounting substrate.
🧩 Build a Complete Stand-Alone Post
A typical custom stand-alone post assembly can consist of:
- 1 × Aluminium 50mm Plain Post
- 1 × BPL100 Square Base Plate
- 1 × Compatible Square Cover Plate – optional
- 1 × Compatible 50mm Post Cap – optional
- Suitable 12g × 1¾” base-to-post screws
- Suitable structural anchors for the mounting surface
This modular system allows you to build the post at the exact height required for your project.

⚠️ Please Note
This product is the BPL100 square base plate only unless otherwise stated.
Aluminium post, cover plate, post cap, base-to-post screws and structural mounting anchors are sold separately unless specifically included in the selected product option.
The recommended 12g × 1¾” screws are used to secure the base plate to the compatible post. These are not the structural anchors used to secure the completed post to concrete or another supporting surface.
Structural anchors must be selected according to the supporting substrate, post height, fencing system and loads imposed on the completed installation.
Where used as part of a swimming pool barrier, the complete post, base plate, anchors and fencing system must comply with applicable Australian Standards and local pool-safety requirements.
The suitability of a surface-mounted post depends on the complete installation. Post height, spacing, wind loading, fence or screen type, mounting substrate and anchor selection must all be considered.
If you are unsure whether the BPL100 is suitable for your application, contact our Technical Support team on 1300 733 066 before ordering.
