Aluminium Balustrade Compliance & Load Data

Our aluminium balustrade system has been load tested to the domestic (Category A) barrier loads in BS 6180:2011 and PD 6688-1-1, on level runs and 35° stairs at the full 1,829mm span. It passed every domestic load within the 25mm deflection limit, with an ultimate failure load more than 9 times the domestic design load. It is for domestic decking, patios, steps and stairs.

✓ Load Tested to BS 6180:2011 Domestic Loads ✓ More Than 9× Domestic Design Load ✓ 1100mm Guarding Height ✓ 100mm Sphere Rule Met ✓ 1,000 Hours Salt Spray

The Standards

BS 6180:2011 — Barriers in and around buildings — Code of practice sets the design geometry for barriers. The minimum horizontal loads a barrier must resist come from BS EN 1991-1-1 and its UK National Annex, with the barrier values given in PD 6688-1-1. Our system was tested to the domestic (Category A) values — see the Load Performance tab →

What This Page Does Not Cover

The test covers domestic (Category A) loads only. It does not cover the supporting structure (deck, wall or slab) or the ground and wall fixings — whether a particular installation complies also depends on it being assembled correctly and fixed to a suitable structural surface.

Black aluminium balustrade with vertical pickets fitted to a raised residential decking area

The aluminium balustrade system installed on a raised residential decking area — 1100mm finished guarding height with vertical picket infill.

Aluminium balustrade rail kit with vertical pickets fitted between two square posts

Rail kit fitted between two 75mm square posts — top and bottom rails with vertical pickets at 96.5mm spacing.

Domestic (Category A) Loads — Results

Each load was applied at the full 1,829mm span on a level run and at a 1,792mm clear span on a 35° stair run. Acceptance: horizontal deflection under load no more than 25mm, return to position on unloading with no significant permanent deformation, and all connections intact.

Load Requirement Level run, 1,829mm Stair run (35°), 1,792mm Result
Line load at the top of the barrier 0.36 kN/m 14.7mm deflection 11.0mm deflection PASS
Distributed load on the infill 0.5 kN/m² 12.2mm deflection 14.2mm deflection PASS
Point load on an individual picket 0.25 kN 18.6mm deflection 24.5mm deflection PASS

Ultimate (Failure) Load

After the domestic load tests, the line load was increased progressively until the system failed.

Configuration Ultimate failure load Margin over 0.36 kN/m
Level run, 1,829mm 702 kg — approx. 3.8 kN/m More than 10×
Stair run (35°), 1,792mm 644 kg — approx. 3.5 kN/m More than 9×
Level run, 1,500mm 738 kg — approx. 4.8 kN/m More than 13×
Stair run (35°), 1,500mm nominal 624 kg — approx. 4.1 kN/m More than 11×
Where Failure Occurred

The failure mode for each configuration at ultimate load is recorded in the full load test report.

Scope

These results are for the domestic (Category A) loads that apply within or serving a single home — 0.36 kN/m line load. The system is for decking, patios, steps and stairs. For any other type of building, contact us before ordering.

Installation Conditions

The tested performance applies when the system is installed to the following conditions.

  1. Maximum clear span 1,829mm between post faces

    Do not exceed the tested span. Runs longer than 1,829mm need additional posts.

  2. Fix posts to a suitable structural surface

    Use fixings rated for the load and the base material. Ground and wall fixings are not supplied.

  3. Maintain the 1100mm finished guarding height

    1100mm above the finished floor level on level runs.

  4. Leave the infill and picket spacing unmodified

    Pickets at 96.5mm, so a 100mm sphere cannot pass.

  5. Use the standard brackets

    Fixed brackets on straight runs and the stair bracket kit on stairs, assembled in accordance with the supplied installation instructions.

  6. Domestic decking, patios, steps and stairs only

    For any other type of building, contact us before ordering.

Supporting Structure & Fixings

This data covers the aluminium balustrade system only. The supporting structure and the ground and wall fixings are the responsibility of the installer.

Test Evidence

Summary of load test report TOL-LTS-001 Rev B. The full report is available to download.

Load Tested — Pass

Line Load — 0.36 kN/m

Applied horizontally at the top of the barrier and held for at least one minute. Level and stair runs passed within the 25mm limit.

Load Tested — Pass

Infill Load — 0.5 kN/m²

Applied across the full picket infill. Level and stair runs passed within the 25mm limit.

Load Tested — Pass

Point Load — 0.25 kN

Applied to an individual picket through a 100mm loading head and held for 90 seconds. Level and stair runs passed within the 25mm limit.

Repeated Loading

10 Load Cycles

Each configuration was loaded and unloaded 10 times at more than double the domestic line load. No bracket or screw loosening was recorded, and rail positions stayed stable to within 1–2mm.

Salt Spray — Pass

1,000 Hours (ASTM B117)

The powder coating passed 1,000 hours of neutral salt spray testing with the highest ratings — no creepage at the scribe, no blistering, no rusting.

Material Verified

Aluminium 6005-T6

Chemical composition verified by test to ASTM B211-12, with all elements within the alloy specification limits.

Frequently Asked Questions

Cannot find your answer? Call us on 01282 526428.

What load has the aluminium balustrade been tested to?

It has been load tested to the domestic (Category A) barrier loads in BS 6180:2011 and PD 6688-1-1: a 0.36 kN/m line load at the top of the barrier, a 0.5 kN/m² load on the infill and a 0.25 kN point load on an individual picket. It passed all three on level runs and 35° stairs at the full 1,829mm span, within the 25mm deflection limit.

How strong is it compared with the domestic requirement?

When the line load was increased to failure, the ultimate failure load was more than 9 times the 0.36 kN/m domestic design load in every configuration tested.

Where can I use this balustrade?

Domestic decking, patios, steps and stairs. For any other type of building, contact us before ordering.

Has it been tested on stairs?

Yes. A stair run was tested at a 35° pitch using the standard stair bracket kit and passed every domestic load, with a guarding height of approximately 1,100mm measured vertically from the pitch line.

What is the finished guarding height of the balustrade?

1100mm on level runs. The post stands 1140mm to the top of the post cap, on a 120mm square base plate.

Does the balustrade meet the 100mm sphere rule?

Yes — the vertical pickets are spaced at 96.5mm, so a 100mm sphere cannot pass through the infill. The infill and picket spacing must be left unmodified.

Is it suitable for coastal locations?

Yes. The powder coating passed 1,000 hours of neutral salt spray testing (ASTM B117) with no creepage at the scribe, no blistering and no rusting. In coastal areas, rinse it down roughly once a month to remove salt build-up.

What is the maximum span between posts?

1,829mm clear span, measured between post faces — do not exceed it. Runs longer than that need additional posts.

Are fixing bolts included?

No — ground and wall fixings are not supplied, as the right fixing depends on what the posts are going into. Each post must be fixed to a suitable structural surface with fixings rated for the load and the base material.

Can I see the load test report?

Yes. Download the full load test report (TOL-LTS-001) as a PDF.
