Pultruded sheet piles represent a very innovative solution for designers working in the construction and mechanical field, so that it was possible to overcome the natural limit of steel, a traditional material that is now outdated, such as the construction of aesthetic barriers.

Why? Because technology that enables the production of pultruded sheet piles can satisfy different types of requirements and complete the achievements, offering the possibility to save costs in a consistent manner.

Pultruded sheet piles can be produced in different models. In all cases, as described above, it is possible to exceed considerably the performance of steel with regard to resistance against corrosive agents – which translates into significant savings from the point of view of costs – but also to lightness and resistance.

At this point we have to go into the details on different types of pultruded sheet piles. It is also possible to build sheet pilesintended to large bearing capacities. These options arise with the specific purpose of replacing sheet pilesmade of iron and they are in this case characterized by many advantages, taking into account the aspects mentioned above, but also the possibility to choose colours. This is very interesting, when speaking about aesthetic barriers that should harmonize with the surrounding environment.

There is also a solution for low bearing capacities; this option arises with the specific purpose of replacing sheet pilesmade of wood or PVC. In this case the specific purpose is the production of aesthetic barriers.

These pultruded sheet piles are usually used for insertions up to 6 meters. In all these cases it is possible to appreciate a special lightness – pultruded sheet piles weigh five times less than those of steel – allowing an excellent handling on a construction site.

Pultruded fiberglass sills represent a very innovative solution in the building sector. When choosing windows and doors, for example, it is necessary to ensure an extremely long life cycle to the structure and, above all, guarantee an excellent level of thermal insulation for the indoor environment.

Pultruded fiberglass sills are also characterized by another feature, that it is to say the possibility of being provided with a smooth finish, a very advantageous option from the aesthetic point of view. Thanks to pultruded fiberglass sills it is possible to reconcile different aspects that have become indispensable in the buildings sector.

The users do not only search for an optimal efficiency from a sustainable point of view, but also keep an eye open to the aesthetic appearance, in order to create a harmony between a window and door or a facade and the indoor environment.

All this is possible thanks to the presence of different colours. This aspect, combined with the fact that profiles are more reduced than those made of aluminium, provides a really interesting aesthetic result that can adapt to different indoor solutions, so that the final user can live comfortably in your house, paying attention to aesthetics that makes your home a pleasant place to live in.

The possibility of choosing among pultruded fiberglass sills with smooth finish– products which have a very different application range compared to sills provided with non-slip finish – is another advantage offered compared to aluminium that implies greater maintenance and an aesthetics which is, in the case of windows and doors, significantly more bulky than as it occurs with pultruded sills.

This happens for the simple fact that a double or triple chamber is not required with fibreglass pultruded profiles.

And ultimately their application is fully customizable and guarantees a perfect result for windows and doors and facades to the final user in line with the most innovative sustainability standards.

Choosing fiberglass pultruded sheet piles is a very interesting advantage for designers who can appreciate  a decisive improvement compared to steel performances, thanks to materials like fiberglass.

When we talk about fiberglass pultruded sheet piles is possible to include the corrosion resistance among their advantages. Several international studies have given clear evidence of it: fiberglass sheet piles are characterized by a higher strength to corrosive action of atmospheric agents and a lightness five times lower compared to steel.

Resistance to corrosion and lightness are two factors that have allowed many designers to replace steel sheet piles with fiberglass pultruded sheet piles. Today, things have obviously changed both in Italy and abroad: awareness about sheet piles produced by pultrusion process is widespread and fiberglass sheet piles have already been installed in different construction sites, so that it is possible to have substantial cost savings in the long term thanks to their above specified technical features.

For this reason companies specialized in producing fiberglass pultruded sheet piles have specialized in the production of various solutions, which are resistant to corrosion and characterized by lightness and an inconceivable steel resistance.

In fact there are sheet piles made ad hoc to replace those made of iron and intended to large bearing capacities. Fiberglass pultruded sheet piles, which may be produced by customized colours, are also used to build aesthetics barriers.

In this case, as already specified, it is necessary to combine aesthetic requirements, a reachable result, because it is possible to colour sheet piles with different shades, with the need for long-life materials, a peculiarity strongly linked to corrosion resistance.

Producing grates in large sizes in the best possible way, it means taking into account the use of materials other than steel. There are certainly many advantages of using steel, but far fewer than those found thanks to the use of fiberglass.

Molded fiberglass gratings with non-slip finish represent a solution which is becoming increasingly central among designers choices. Why? First of all, because fiberglass is a material resistant to the atmospheric agents and to acid and base attacks. This makes the choice of molded fiberglass gratings – perfectly tailor-made – a congenial option, when it comes to produce grates exposed to the outside for the most part of their extension.

Another advantage of this choice on molded fiberglass gratings with non-slip finish concerns the fact that fiberglass, though it is very light in weight, is able to withstand high load capacities that may reach about 50 quintals.

Due to its lower relative density, it is definitely stronger than steel at equal weight. We previously have referred to as moulding process represents the perfect solution for those who would like to have a perfect production according to their needs, with the possibility of customizing the end product and making it economically advantageous from the point of view of immediate costs and sustainable in the long term. Fiberglass, as already specified, is extremely resistant to corrosion and has become synonymous with a longer useful life of products.

Ease of assembly, lightness of the entire structure, long-term maintenance savings: these and many other benefits of molded fiberglass gratings with non-slip finish, sustainable and technically advanced solutions for grates in large sizes that can be produced with a technical perfection, which is unthinkable by steel.

The lightness of fiberglass pultruded sheet piles has long been known. People facing everyday problematic issues related to job as a designer know perfectly how it is important that efficiency and cost benefits are reconciled.

When you think about the installation of structural components of significant sizes, such as sheet piles, this could become difficult, unless the choice is oriented towards technically innovative solutions like fiberglass pultruded sheet piles.

Fortunately, this option has gained ground against sheet pilesmade of reinforced concrete, PVC and steel in the last few years. What are the main advantages of choosing fiberglass pultruded sheet piles? The main aspect to consider is lightness in these cases.

Indeed, fiberglass sheet piles weigh about five times less than steel. The arithmetic is quite simple: choosing fiberglass sheet piles for their own projects, it means making room for substantial cost savings both for transportation in construction sites and on site handling.

All this without sacrificing anything with regard to quality and resistance. The advantages of pultruded sheet piles are not restricted to lightness, a very important peculiarity.

But it must not be forgotten the fact that the use of fiberglass has become synonymous with anti-corrosion and that sheet piles produced thanks to a pultrusion process are easy to work with also in a construction site, so that steps to be undertaken before installation are much more quickly and efficiently.

Finally, the aesthetic aspect should not be overlooked. Fiberglass pultruded sheet piles – apart from being much lighter than steel – can be produced with different colours. This offers a great advantage to integrate the installation with the surrounding environment.

It is also possible to customize fiberglass pultruded sheet piles, producing them with the aim of replacing those made of iron or PVC, according to the needs.

Pultruded materials present remarkable features. Even though Saimex Srl is already operating under certified conditions, it was decided to further test the capacity of their product. Therefore, flexural and pull tests were commissioned to the Technical University of Milan and performed by a technology bearing the company’s logo: Deck System, a special deck in composite material, which is light and extremely versatile. Its applications range from pedestrian bridge to pedestrian paths.

Flexural test

It was performed on sampled panels Deck System HD supplied by Saimex Srl. The single elements had the following sizes: 501.9 mm x 1,800 mm x 40 mm (Figure 2).

The promotion campaign has planned to perform three flexural load-controlled tests in a four-point static scheme and a clear distance between the supports of 1,500 mm (Figure 3). The purpose of this test is to verify if the elements are shifted towards the mid-span using the working load.

Test no. 1:

–   maximum deflection limit per working load Pe = 3.10 kN kept for 10 minutes: 7 mm;

–   maximum load applied: Pu = 20 kN

Results:

  • no breakage or failure due to Pu;
  • minimum residual deformation of post-discharge (u = 0.940 mm).

Test no. 2:

–   maximum deflection limit per working load Pe = 3.10 kN kept for 10 minutes: 7 mm;

–   maximum load applied: Pu = 25 kN

Results:

  • no breakage or failure due to Pu;
  • minimum residual deformation of post-discharge (u = 1.759 mm).

Test no. 3:

–   maximum deflection limit per working load Pe = 3.10 kN kept for 10 minutes: 7 mm;

–   maximum load applied: Pu = 25 kN

Results:

  • no breakage or failure due to Pu;
  • minimum residual deformation of post-discharge (u = 1.790 mm).

The maximum arrows were reached at mid-span for a maximum load applied respectively in all the three tests and are, as follows:

 

Test no. fmid-span [mm]
1 5,221
2 5,015
3 5,562

Table 1: maximum mid-span deflection of the samples

Therefore the tests give evidence to the considerable ability of Pultruded composite materials produced by Saimex Srl, which not only confirm, but also overcome by far the expectations of the Technical University of Milan and of the company and the values prescribed by the current regulations relating to composite materials (UNI EN 13706).
