1. GENERAL
This manual deals with driven and jacked SSAB's RR and
RRs piles, shaft grouted driven CSG-RR piles and drilled
RD and RDs piles. It covers all pile sizes from RR75 to RR/
RD1200. This manual describes the basics of the design of
SSAB's steel piles and provides advice on their handling
and installation, quality control, measurements and
documentation. This manual is supplemented by product
brochures on RR and RRs piles and RD and RDs piles,
which describe the applications, materials, structures and
dimensions of steel piles on a general level.
This manual is based on the Finnish Piling Manual PO-
2016 (RIL 254-2016). This manual is used when the site
has been designed according to the Eurocodes system. If
the piling of a site is designed using the maximum allowed
pile loads method, the RR and RD Piling Instructions
are followed in the design of steel piles. The installation,
handling and end-of-driving instructions presented
here can be used where applicable if the site has been
designed based on maximum allowed pile loads.
This manual applies to both individual piles and
pile groups. They can be applied to the design and
implementation of support structures made of SSAB's
steel piles, such as the RD pile wall, various Combi wall
structures, and driven or drilled steel pipe piles used in
other retaining walls.
2. SSAB’S STEEL PILES
2.1 General
SSAB has CE marking, based on European Technical
Assessment (ETA 12/0526), which is the most
comprehensive CE marking to be granted to pile
structures made of structural steel. It covers the entire
pile structure, manifests the requirements and conformity
of the mechanical splices, and establishes that the
product has been manufactured specifically for piling.
The approval is based on detailed load tests, especially
on splices, continuous quality control during the various
phases of production, and traceability of materials.
Use of SSAB's CE marked piles in a construction
project ensures the durability and performance of
foundations. Tested products guarantee problem-free
site installation.
Internal splices of RR piles are not covered by the CE
marking.
SSAB's steel piles meet the requirements presented in
Finnish Piling Manual PO-2016 (RIL 254-2016) for pile
materials and accessories.
SSAB's steel piles have SP Technical Research Institute of
Sweden quality certificate – P-mark (0656/94).
2.2 Steel grades and standards
The steel grades and chemical composition and
mechanical properties of SSAB's steel piles are presented
in Table 1.
The availability of steel grades by pile types and diameter
and wall thickness are presented in Secs. 2.3.1 and 2.4.1.
Against special order, the piles may also be delivered in
X grades according to API5L standard.
The technical delivery terms of the piles comply with
standard EN 10219-1. Dimensions and tolerances
comply with standard EN 10219-2. SSAB's steel piles
with mechanical splices are manufactured to tolerances
stricter than those of standard EN 10219-2. A material
certificate of type 3.1 specified in EN 10204 is provided for
the pile material.
