Versatile range of steel pile dimensions

SSAB’s versatile range of steel pile dimensions enables you to select the optimal size, steel grade and length for your project. Piles are installed with driven or drilled technology and come in diameters of 76.1–1220 mm (3.0–40.0 in.) and thicknesses of 6.3–23 mm (0.25–0.91 in.). SSAB’s steel grades especially for piling are S440J2H and S550J2H.

Retaining walls

Build stronger with high performance RRs and RDs steel piles

Our high-strength RRs and RDs piles, in combination with efficient designing, easy and quick installation, lower environmental impact than traditional piling create a solution that is now stronger than ever.

By using the higher steel grade S550J2H, the piles load-bearing capacity can be added by 25% over that of steel grade S440J2H. The increased load-bearing capacity of the pile can be utilised by using smaller piles or decreasing the number of piles. For the customer, this means a significant improvement in the overall economy of the project.

High performance RRs® and RDs® piles

Higher load-bearing capacity and lower costs

RRs pile selection includes seven common pile sizes

The excellent properties of the RR piles, such as splicing easily and quickly with an external friction splice as well as other pile accessories, are utilized also in RRs piles manufactured of high-strength steel.

Advantages of the high-strength steel S550J2H in SSAB's RRs piles:

By using the higher steel grade S550J2H, pile’s load-bearing capacity can be added by 25 % over that of traditional RR piles. The increased load-bearing capacity of the pile can be utilized by decreasing the number of piles.

Alternatively, a RRs pile made of high strength steel can replace a RR pile with bigger size. Good example of this is RRs125/6.3 pile size, which can easily replace pile size RR115/8.

HDPE coated piles for renovation of sheet piled quay wall in West Harbour

West Harbour is located at Jätkäsaari, where construction of Helsinki’s new maritime district is progressing at full speed. Jätkäsaari is gradually being transformed into a district offering residential areas, workplaces and services. The shore area of Jätkäsaari was previously used for industrial and harbour purposes.

The Port of Helsinki is developing West Harbour and building a new terminal area at the tip of Jätkäsaari, where the new West Terminal 2 is due for completion in spring 2017. The new passenger pavilion will, together with the old West Terminal 1, provide a smooth travel experience for the millions of passengers travelling between Helsinki and Tallinn each year. The route across the sea between the cities is one of the busiest in the world, and its passenger numbers are growing constantly.

Figure 1. West harbour maps in 2016 and 2017.

SSAB has delivered steel piles for the quay structures in Ferry berth LJ6. Main contractor of the project was Suomen Vesityö Oy and the designer has been FCG Oy. Piling work has been done by Kantolan Paalutus Oy. Quay structures consist of sheet pile wall which is supported by steel piles. Larssen 605K sheet piles are 15 - 16 meter long and include protective painting in the upper part with length 5,0 m. There are in total 52 RR450/12.5 piles. Steel grade is S355J2H. Pipe piles are made of two parts. Lower parts of piles are 18-19 meters long and upper parts are 12 meters long. Upper parts are protected with HDPE coating. Piles are equipped with rock shoes.

Figure 2. Installation of sheet piles.

Construction work started with pulling up the sheet piles of the existing quay structure. The old erosion plate (thickness 0.5 m, width 10.0 m) in the bottom was demolished without problems. After that new sheet piles were installed, RR450 pipe piles were pile was driven in every third of the sheet pile channels. When all sheet piles and RR450 piles were installed, they were cut from the designed level. After that the capping beam could be cast. The work was completed successfully in spite of very small workspace and existing ship and ferry traffic.

Figure 3. RR piles supporting sheet pile wall in ferry berth LJ6.

Figure 4. All sheet piles and RR450 piles installed and structure is ready for capping beam casting.

Figure 5. All sheet piles and RR450 piles installed.

Piles were delivered with HDPE (High Density Polyethene) coating to protect the piles against corrosion and mechanical stress caused by ice conditions and propeller slipstream. The 3-layer coating consists of epoxy, adhesion and polyethylene, layers. HDPE coating is done at SSAB’s Oulainen works. Piles (L= 10-18 m) are coated over the full length at the same time. Coating is removed from the end of the pile to enable welding of the pile.

In this project it was proven again that HDPE coating stands very well handling and installation of piles without damages to the coating surface. HDPE coated piles were used the first time in the renovation of West harbor’s quay structures already in 2007. The experience during the ten years has been very good.

Figure 6. HDPE coated piles waiting for transportation at SSAB’s Oulainen works.

Renovation of the quay structures in Ferry berth LJ6 will continue during summer 2017. Quay structure consisting of sheet pile wall supported by steel piles as well as the installation principle will remain the same .

Mechanical splice for RD320 pile size

Threaded mechanical splice has now been tested also for pile size RD320. Splice may be used with wall thicknesses 10 mm and 12.5 mm. It covers material strengths up to S460MH.
Since steel piles aren’t covered by hEN (Harmonized European Standard), the approval process is done according to ETA (European Technical Assessment) process. In ETA process the requirements for products are given in other harmonized technical specifications such as European Assessment Documents (EADs) or European Technical Approval Guidelines (ETAGs used as EAD). For steel piles EAD 200005-00-0103 is used.

According to this EAD the testing of threaded splice for RD320 consists of:

  • robustness test by tightening
  • bending test to define the bending resistance and bending stiffness
  • compression test
  • tension test.

Figure 1. Bending test at Tampere University of Technology

Figure 2. Tension test at RISE Research Institute of Sweden

Above tests were accomplished at RISE Research Institute of Sweden in Borås and at Tampere University of Technology in Tampere.

Test results fulfilled the requirements of EAD and all the test reports have been sent to VTT Technical Research Centre of Finland. VTT is working as a TAB (Technical Assessment Body) in Finland and will check through all the test reports before granting an ETA for the product.

After ETA has been granted, RD320 will be added to ETA 12/0526 which covers all the SSAB’s pile products and it may be CE marked.

SSAB participated at the Pfahl-Symposium 2017 in Braunschweig, Germany

Technical University of Braunschweig organizes a Pfahl-Symposium, Pile Conference, every second year. This year also SSAB participated this event on 23rd and 24th of February.

Antti Perälä, Technology Manager of SSAB Tubular products, Infra, wrote a paper and also held a presentation at the conference. Topic of the paper was RD pile wall – A retaining wall of drilled steel pipe piles. Due to drilling as an installation method, RD pile wall can be used in demanding soil conditions where installation of traditional retaining wall structures is very difficult or even impossible.

Figure 1. Antti Perälä keeping a presentation of RD pile wall

Pfahl-Symposium 2017 gathered approximately 350 professionals from Continental Europe, mainly from Germany and the Netherlands. SSAB’s piling products, especially RD pile wall and micropiles, were found interesting due to some unique features. SSAB’s micropile products have been used successfully for over 30 years in the Nordic countries. They suit very well also to the soil conditions in Central Europe.

Piling work in progress in the construction of new residential district Ranta-Tampella in Tampere, Finland

During the coming years, Ranta-Tampella is one of the largest construction areas in Tampere. The area will be constructed in many phases at Tampella lakeside area as a downtown extension by the shore of Näsijärvi lake. Over 2,000 new apartments will be constructed to the area of approximately 16.5 hectares.

Ranta-Tampella area development was allowed by construction of Rantatunneli tunnel, a 2.3 kilometre road tunnel – the longest in Finland. The tunnel freed up a large swath of central Tampere’s northern areas for the use of residents. Rock material generated during the tunnel excavation has been used to fill in the waterfront for the park being created in the Ranta-Tampella district.

Ranta-Tampella area development project has many players and the total value of the project is approximately EUR 900 million. YIT is the biggest constructor at the area and it has building permit for floor area of 80,000 square metres for its plots. The preconstruction of the area was started in the summer 2014 and the whole area is expected to be completed by 2030.

Figure 1. Over 2,000 new apartments will be constructed to Ranta-Tampella, the area of approximately 16.5 hectares.

YIT started the construction of Ranta-Tampella area project in November 2016. The first phase to be constructed is Asunto Oy Tampereen Näsinkeula apartment building. Ranta-Tampella has aroused strong interest and Näsinkeula apartments were reserved in an exceptionally short time when the advance publicity started in the beginning of September. The central location close the city centre and by the Näsijärvi lake creates a good basis for a unique residential area.

Figure 2. Building work has started from apartment buildings Näsinkeula and Kanavanvahti and two parking facilities.

Suomen Teräspaalutus Oy has been responsible for piling Asunto Oy Tampereen Näsinkeula apartment building, Asunto Oy Tampereen Kanavanvahti apartment building and two parking facilities. Because of demand soil conditions and embankment made by blasted rock used pile type was drilled piles. Work included in total 623 pieces of RD piles (411 tons) and all piles were S550J2H steel grade. Thanks to high-strength steel, less piles could be used. Piling work started in October 2016 for Tampereen Näsinkeula where RDs220/12.5 piles were used. Piling for Tampereen Kanavanvahti started in January 2017. RDs170/12.5 and RDs140/10 piles were used. Piling for the parking facility of Keulakortteli, block of houses where Näsinkeula belongs to, was done in the turn of the year using RDs220/12.5 and RRs270/12.5 piles. Piling for the parking facility of Kanavakortteli, block of houses where Kanavanvahti belongs to, was done in February using RDs170/12.5 piles.

Figure 3. Piling for Asunto Oy Tampereen Kanavanvahti apartment building started in January 2017.

Soil conditions in Ranta-Tampella area consist mainly of different fill layers. Materials used in these fills vary a lot. Old fill layers have been mainly removed to the water level of Näsijärvi lake. New layers consist of boulders and crushed bedrock from excavation of Rantatunneli. Pile lengths in these first two projects varied from 4 m to 15 m.

Figure 4. Suomen Teräspaalutus Oy piling in Ranta-Tampella.

YIT’s third apartment building, called Ykköspurje, will be built earliest during summer 2017. Construction work is dependent on the market demand for the apartments.
Apart from YIT, also other construction companies are involved in Ranta-Tampella. One of them is PEAB, who aims to start the construction work during summer 2017. Their block includes five apartment buildings.

SSAB’s tenth Steel Pile Day 2017 in Helsinki

A total of 300 foundation construction experts gathered together for SSAB’s Steel Pile Day held in Helsinki on January 19, 2017. Contractors, designers, authorities and students who participated in the event were offered an introduction to SSAB’s pile products. The event also showcased projects in which the company’s RR and RD piles have been used to construct dock structures and building foundations.

Figure 1. A total of 300 foundation construction experts gathered together for SSAB’s Steel Pile Day held in Helsinki on January 19, 2017.

Kari Väliaho, General Manager, Tubular Products opened the tenth ever foundation construction event. Developed in Finland, RR and RD piles have been in use for three decades now. Driven steel piles were used for the first time in the construction of the dock in Oulu’s Oritkari in Finland, and the expansion of Imatra’s cardboard factory in 1987 represents the first-ever micropile application. The majority of the piles produced by SSAB are exported.

‘SSAB has full control over its production and processing chain. All our steel pile products are manufactured at our own factories using steel produced in Raahe. This allows us to control the entire process, offer reliable deliveries and ensure that our piles meet the quality and product requirements. Our products are delivered to customers cost-efficiently by road from the factories or from our subcontractors’ premises,’ explains Marko Maukonen, Supply Chain Manager, Infra.

Use of RR and RD piles and RD pile walls in customers’ building projects

Project Manager Reino Heikinheimo from Ramboll Finland Oy introduced Turku University Hospital’s T3 project in which HDPE RD® piles were used for the foundation. With the new building built on top of a railway and motorway, the project was extremely challenging.

Roger Starck from the Swedish company BESAB AB talked about projects carried out by the company where SSAB’s RR and RD piles had been used to reinforce the foundations of old or historical buildings.

Construction Manager Pasi Mäkinen from Skanska Infra Oy presented the company’s K6 office building project. The 8-storey building, which has 3 additional floors underground, is located in a densely built area in Sörnäinen, Helsinki.

Piet van Breukelen from SSAB introduced an RD pile wall project carried out at Peterhead Port in Scotland, which represents our most extensive pile wall project outside the Nordic countries to date.

YIT-Rakennus Oy’s construction manager Juha Vunneli offered an update on the progress of the PasilaTripla project in Pasila, Helsinki. The project involves the construction of a shopping centre Tripla, high-rise buildings and a new residential area.

In his presentation, Antti Perälä Technology Manager, Infra covered the Hospital Nova project in Central Finland and the Kiiruu School project in Somero, in which the steel grade of RR and RD piles was upgraded to S550J2H, which resulted in considerable savings.

Figure 2. In addition to the presentations, the event included an exhibition of SSAB’s products

New products and updated dimensioning programs

SSAB’s range of driven micropiles has been complemented with new driven pile elements made of high-strength steel (S550J2H), such as the RRs220/10 and RRs220/12.5 piles.

Steel Pile Day also showcased the company’s expandable rock bolts (ERBs), suitable for reinforcing road tunnels and mines. SSAB has three decades of experience in manufacturing ERBs at its factory in Virsbo, Sweden.

SSAB’s dimensioning program RRPileCalc was updated in January while the PileWallCalc 2.01.0 program now also includes the Swedish and Norwegian standards.

SSAB has also launched a new dimensioning program, FrameCalc, which covers SSAB’s standard dimensions and steel grades from S355 to S700. The solution is designed for the automated design of steel trusses.

In addition, Tibnor’s product range was introduced to infrastructure builders at the event, including sheet piles and beams required in the construction of sheet pile walls.

Participants’ comments on Steel Pile Day

‘We have used RD piles and RD pile walls in applications such as foundations for industrial buildings. I was particularly interested to hear the presentations by contractors and to learn more about their experiences of these products,’ says SRV Infra Oy’s construction manager Janne Viitasalo, who participates in the Steel Pile Day almost every year.

‘Bringing together all the designers and contractors, this annual event offers an opportunity to meet face-to-face with collaboration partners you usually communicate with by phone or email,’ he adds.

Figure 3. Janne Viitasalo, SRV Infra Oy

Miia Paatsema, a project manager at the City of Helsinki Geotechnical Department, is another regular at the Steel Pile Day.

‘I was particularly interested in the Scottish port case, which provided me with new ideas on how to proceed with the design of our project. We could utilise the guide frame that was used in the installation of the pile wall in the port project,’ says Miia Paatsema.

Figure 4. Miia Paatsema, the City of Helsinki, Geotechnical Department

Construction manager Sami Kari from Lemminkäinen Infra Oy is also a familiar face at the annual event.

‘We have used SSAB’s piles in our residential building projects. At the Finnoo station of the West Metro line, we deployed RD pile walls, which are ideal for challenging applications,’ Sami Kari explains.

‘I particularly looked forward to hearing the presentations on other work sites as it’s always interesting to learn how other companies carry out these projects,’ he continues.

Figure 5. Sami Kari, Lemminkäinen Infra Oy

Civil engineering company Arcus Oy’s branch manager Jaakko Heikkilä regards the Steel Pile Day as an excellent opportunity to update his knowledge of foundation construction products supplied by SSAB.

In the design of his infrastructure projects, such as construction of bridges, he has used large-diameter RR and RD piles.

‘The use of drilled piles has increased as they provide higher load bearing capacity particularly in bridge applications. At the installation stage, the noise and vibration levels are lower with drilled piles than with driven piles,’ Jaakko Heikkilä says.
