Last week one of the world’s largest and most trusted Total Quality Assurance Providers, Intertek, completed Load, Pull and Compression Force Testing on 10 x Kwiktech Builds, specifically recommended for their “real world application”, with the hollow metal failing in 8 out of 10 cases and a Maximum Load Force recorded of 15.6 kN (1,590 kg).
All Kwiktech Builds were tested over a 1m span with 5 fabricated from galvanised steel and an identical 5 from aluminium, with steel outperforming aluminium across all Load and Compression Force tests. The only tests resulting in Kwiktech failing before the hollow metal were the 2 Pull (Tensile) Tests, with both tests exceeding 4.0 kN (408 kg) before failing.
Load Force Tests were conducted on 4 x Kwiktech Builds (2 x Galvanised Steel and 2 x Aluminium) comprising of a single 1m length of 38×25 connected to 2 x 50×50 posts. Each metal was tested with the Universal Connector in both a horizontal and vertical position.
Pull Force (Tensile) Tests were conducted on 2 x Kwiktech Builds (1 x Galvanised Steel and 1 x Aluminium) comprising of a single 300mm length of 38×25 connected to 1 x 50×50 post.
Compression Force Tests were conducted on 4 x Kwiktech Trusses (2 x Galvanised Steel and 2 x Aluminium) comprising of a 1m Flat Truss in both a single-braced and double-braced configuration.
All builds were connected using Kwiktech’s Universal and Rail Connectors.
Load Force Tests were up first with the galvanised steel connected in a vertical position (Load Force applied to the 25mm side of the RHS) recording the best results with a minimal deflection of 3mm at 3.0 kN (306 kg) and the 38x25x1.2mm RHS failing at 3.3 kN (337 kg).
When tested in its horizontal position (Load Force applied to the 38mm side of the RHS) the 38x25x1.2mm RHS failed at 2.4 kN (245 kg).
Kwiktech outperformed the hollow metal in all configurations, with the Galvanised Steel outperforming the Aluminium by an average of 38%.
The results of the 4 x Load Tests clearly prove that when used as specifically designed, to act as a Brace Connection for standard fencing materials, Kwiktech ensures your lightweight hollow metal framework is as strong as the hollow metal itself.
Following the successful Load Force Tests it was time to turn our attention to Compression Testing to be conducted on 4 x 1m Flat Trusses comprising of 2 x lengths of 50×50 connected with 5 x lengths of 38×25 (singled braced) and 7 x lengths of 38×25 (cross-braced).
Kwiktech was specifically designed to act as a Brace Connection acting under Compression Force, so when we turned our attention to the Flat Trusses it was fair to say we were more than excited to see the results. And we were not disappointed.
In both the single-braced and double-braced configurations the hollow metal failed in all 4 tests, with the Aluminium buckling at 8.5 kN (867 kg) and the Galvanised Steel recording an impressive 15.6 kN (1,590 kg) before failing.
In all 8 Load and Compression Force Tests, where the hollow metal buckled, not one single Kwiktech Build suffered any sideways deflection.
When tested in a vertical position (Universal Connector on its side with the Load Force applied to the 25mm side of the RHS) the secured Locking Angle recorded no movement or slipping whatsoever.
The Official Intertek Report is due by the end of the week and we will make the official results, and the report itself, available as soon as possible.
Following discussions with the Intertek Team during the testing, we agreed the only way to test Kwiktech’s true limits is to increase the thickness of the hollow metal. Drastically.
Kwiktech was specifically designed to connect readily-available and cost-effective standard fencing materials (50×50 SHS and 38×25 RHS in both Galvanised Steel and Aluminium) with minimal fuss and no experience required, enabling DIY’ers to take on fabrication projects both around the home and in commercial ventures with only a tape measure and standard power tools. While sourcing and testing thicker, stronger hollow metal is a possibility, it is simply not practical for DIY’ers to take on projects with such materials. Kwiktech reduces costs and increases fabrication time for lightweight framework, and that is the way we want it to stay.
