Large diameter RR and RD piles are based on spirally welded high quality steel pipes. The pile range covers sizes 400 to 1200 mm. Large diameter RR and RD piles can also be made in customer specific diameters and wall thicknesses.
For more detailed sectional properties and steel grades of the piles see SSAB’s RR and RD piles design and installation manual.
Driven RR large diameter piles (RR400–RR1200) are steel pipe piles consisting of a spirally welded steel pipe and an optional pile tip.
The key benefits include high load-bearing capacity, great stiffness and bending strength due to their shape, and high installation strength due to the steel's strength.Drilled RD large diameter piles (RD400–RD1200) are special piles installed by drilling in difficult ground and environmental conditions.
Piles consist of a longitudinally or spirally welded steel pipe. They may be drilled through all natural soil layers all the way into bedrock, with small deviations in position and inclination.
For structures in severe conditions, it may be beneficial to protect entire piles or parts with external coatings.
SSAB can deliver pile pipes with several protective coating methods.
Availability of large diameter piles: standard wall thicknesses and diameters. Lengths available up to 39 meters without splicing. For project specific dimensions, please contact our sales.

Our flexible manufacturing process of large diameter piles enables use of project specific dimensions. Cost savings can be found through project specific material thickness as well as steel grade used in piles.
Piles manufactured to the length specified by customer help to minimize splice welding on site and bring considerable savings in construction costs and time. Up to 39 m long large diameter RR and RD piles without splice welds can be manufactured to order. The longest RR piles with welded splices delivered by SSAB have been 45 m long.
Software for fast and easy design
RRPileCalc is a design program for SSAB's steel piles. Eurocodes as well as National codes and instructions are applied in the end-bearing pile design.
PileWallCalc design tool enables easy calculation of cross section properties and bending resistances of the pile walls. The program calculates the bending resistances and normal force resistances of RD® pile wall, Combi wall and Zig-Zag Combi wall.
SSAB develops new products and services in order to improve our customers’ performance in sustainability and overall efficiency.
Life cycle assessment data for SSAB’s products are available in the form of Environmental product declarations (EPDs). Manufacturing chain from raw material to finished product is carefully managed.
SSAB has introduced CE marking for infrastructure products. Declarations of Performance (DoP) indicate the technical characteristics of CE-marked products.
With support from the Norwegian Government, Northern Lights is developing an open and flexible infrastructure enabling decarbonisation of Norwegian and European industry. The development is the transport and storage component of Longship, the Norwegian Government’s full-scale carbon capture and storage project.
Metsä Fibre, part of Metsä Group, is building a new bioproduct mill in Kemi next to existing pulp mill. The new mill will consume 7.6 million m3 of wood in a year and produce 1.5 million tons of pulp of which 70 % will be exported. Metsä Fibre’s investment to Kemi bioproduct mill is worth 1.85 billion euros and it will increase Finland’s export revenue with 0.5 billion euros annually. SSAB supplied displacement piles and micropiles for this new bioproduct mill, which Metsä Fibre is currently building in Kemi, Finland.
