How To Install Aluminium Balustrade Wire Railings Step By Step
With every post fixed, drilled and verified, you are ready to begin the aluminium balustrade wire installation. This stage involves fitting the handrail, support pickets and wire ropes to create a secure, contemporary balustrade system suitable for decks, patios and balconies.
If you are researching how to install aluminium balustrade wire railings, it is important to follow the correct installation sequence. The support picket is installed before the wire ropes are threaded, providing the mid-span support needed to keep the wires parallel, evenly spaced and correctly tensioned.
This guide explains how to install aluminium balustrade wire railings using the NeoTimber® system. Follow the instructions below for straight, corner and stair installations to achieve a professional and long-lasting result.
Straight Railing Installation
Step 1: Installing The Handrail For Aluminium Wire Balustrade Installation
Slide the handrail brackets onto both ends of the handrail. Position the handrail between the posts on the final balustrade line and mark the bracket fixing hole positions on each post. Drill pilot holes at the marked positions and secure the handrail brackets to the posts using the screws provided.
If installing multiple consecutive bays, leave the bracket fixings slightly loose at this stage - don't fully tighten until all bays are aligned.
Step 2: Installing The Support Picket
Position the support picket centrally along the handrail. Mark the picket base fixing positions on the deck surface, drill pilot holes, and secure the picket base using the fixings provided. Once the picket base is secure and correctly aligned, fit the base cover to complete the assembly.
The support picket is an important component of aluminium balustrade wire installation, helping maintain wire alignment and reducing deflection across longer spans.
Step 3: Threading Wire Ropes Through The Balustrade System
Starting at one end post, feed each threaded bolt through the pre-drilled wire holes in the post, working from the bottom wire upward. Attach a wire tensioner to the end of each wire rope and connect it to the corresponding threaded bolt, twisting firmly to secure.
Once all wires are secured to the end post, feed each wire rope through the matching holes in the support picket and continue through to the next post. Attach a tensioner and threaded bolt at each post in turn, repeating until all wires are routed through the full run.
Step 4: Tensioning Wire Ropes And Final Fixing
Tension each wire rope sequentially using a hex key to tighten the three locking nuts on each tensioner. Correct tensioning is one of the most important parts of aluminium balustrade wire installation and helps ensure the completed system remains secure, level and visually consistent.
Work evenly across all wires - tighten each wire a little at a time rather than fully tensioning one before moving to the next. This keeps tension consistent and wires parallel throughout the run.
Once correct tension is achieved across all wires, re-check and fully tighten all handrail bracket fixings to complete the installation.
Final Checks Before Completing Your Wire Balustrade Installation
- All post caps and base cover trims are fitted and secure
- Handrail is level and all bracket fixings are fully tightened
- Support picket is plumb and its base cover is fitted
- All wire ropes are parallel, evenly tensioned, and correctly spaced
- All locking nuts are fully tightened
90° Corner Installation
The 90° corner configuration connects two perpendicular bays at a shared corner post. This aluminium balustrade wire installation follows the same principles as a straight run but incorporates a dedicated corner post, an aluminium insert plate and a bay-by-bay wire tensioning sequence.
Before you begin: the corner post serves both bays simultaneously. Wire ropes from Bay 1 fix to the outer face of the corner post in the standard way. Wire ropes from Bay 2 fix internally via the aluminium insert plate installed in Step 3. Install and fully tension Bay 1 before beginning Bay 2.
Step 1: Fixing Handrail Brackets For Both Bays
Slide the handrail brackets onto the ends of both handrail sections. Position each handrail between its respective posts - the two sections must form a precise 90° angle at the corner post. Mark all bracket fixing positions using the paper setting-out template, drill pilot holes, and fix the brackets to the posts using the screws provided. Do not fully tighten fixings at this stage.
Step 2: Installing Support Pickets For Both Bays
Install a support picket centrally in each bay, following the same method as Step 2 of the straight railing installation. Fix each picket base to the deck, verify alignment, and fit the base covers.
Step 3: Threading And Tensioning Wire Ropes - Bay 1
Thread and tension all wire ropes for Bay 1 following the same method as Steps 3 and 4 of the straight railing installation. Fix and tension wires from the Bay 1 end post through the support picket to the corner post, securing to the threaded bolts on the outer face of the corner post. Tighten the locking nuts evenly to achieve consistent tension before moving on to Bay 2.
Step 4: Installing The Aluminium Insert Plate Into The Corner Post
The aluminium insert plate carries pre-fixed nuts that align with the wire rope holes on the Bay 2 face of the corner post. Slide the insert plate into the internal cavity of the corner post and align it precisely with the pre-drilled wire holes on the Bay 2 face. Once aligned, secure the insert plate firmly through the pre-drilled holes.
The insert plate ensures wire ropes from both bays sit at exactly the same height without requiring wires to cross or intersect inside the post.
Step 5: Threading And Tensioning Wire Ropes - Bay 2
Thread wire ropes for Bay 2 from its end post through the support picket to the corner post, securing each wire to the aluminium insert plate via the threaded bolts on the Bay 2 face. Tension all Bay 2 wire ropes evenly using a hex key, following the same sequential method used for Bay 1. Once correct tension is achieved across both bays, fully tighten all handrail bracket fixings to complete the installation.
Final Check: 90° Corner Installation
- Insert plate is secure and correctly aligned within the corner post
- Wire ropes in both bays are parallel, evenly tensioned, and at the same height
- All locking nuts are fully tightened
- All handrail bracket fixings are fully tightened
- All post caps, base covers, and picket covers are fitted and secure
Stair Railing Installation
The stair wire railing follows the same wire threading and tensioning method as the straight installation but uses an angled handrail and adjustable bracket backing plates to follow the stair pitch. This variation of aluminium balustrade wire installation is specifically designed to provide a safe and attractive balustrade solution for staircases.
One important measurement to confirm before you begin: on a stair installation, the post-to-post spacing is measured along the slope of the staircase, not horizontally. For a full railing section, this sloping distance must be 1,910mm. Use the paper setting-out template to confirm that wire rope holes in the posts are aligned with the stair angle before any posts are permanently fixed.
Step 1: Positioning And Fixing Stair Posts
Measure and mark the location of all stair posts, confirming the sloping post-to-post distance is 1,910mm for a full railing section. Ensure each post is positioned at least 50mm from the deck edge. Drill pilot holes and fix posts using M8 timber screws for timber substrates or M8 expansion bolts for concrete. Fit post caps and base cover trims once all posts are fixed and verified as plumb.
Step 2: Setting The Handrail Angle And Installing Adjustable Brackets
Place the handrail between the posts and set it to follow the stair angle. Cut to length if required. Align the adjustable bracket backing plates to the underside of the handrail and centre each bracket on the posts. Mark the fixing hole positions, drill pilot holes, and secure the brackets to the posts using the appropriate screws.
Use the paper setting-out template to confirm wire rope hole alignment is correct relative to the stair angle before tightening any fixings fully.
Step 3: Fixing The Top Handrail Brackets
Slide the top handrail brackets onto both ends of the handrail. Position the handrail onto the installed posts and brackets, confirming the angle correctly follows the stair pitch. Mark the bracket fixing positions, drill pilot holes, and secure using the appropriate screws.
Step 4: Installing The Support Picket
Position the support picket at the mid-point of the handrail. Mark the picket base fixing positions on the deck surface, drill pilot holes, and fix the base using the screws provided. On the underside of the handrail, mark and drill the picket bracket fixing holes and secure the bracket to the handrail.
Step 5: Threading The Wire Ropes
Thread each wire rope through the pre-drilled holes in the end post and support picket, following the same method as the straight railing installation. Attach the supplied connectors and threaded bolts to each wire end at the end post. Continue feeding wire ropes across the run and secure the opposite ends to the final post using the threaded bolts and tensioners provided.
Step 6: Tensioning Wire Ropes And Final Fixing
Tension each wire rope sequentially using a hex key or wrench, working evenly across all wires to achieve consistent tension and straight cable alignment along the stair slope. Carry out final checks to confirm all bracket fixings are fully tightened, all wire locking nuts are secure, and the completed balustrade is correctly aligned along the stair line and stable under lateral load.
Final Check: Stair Railing
- All post caps and base cover trims are fitted and secure
- Handrail correctly follows the stair angle and all bracket fixings are fully tightened
- Support picket is secure at both base and handrail fixing points
- All wire ropes are parallel relative to the stair slope, evenly tensioned, and all locking nuts are fully tightened
If all checks have been completed successfully, your aluminium balustrade wire installation is complete. The finished system should provide a secure, low-maintenance and contemporary railing solution for many years to come.
