Based on high-strength steel, the SSAB W230 side barrier is a completely new safety barrier system completely compatible with commonly-used side barriers in Finland. The barrier is compliant with the containment level N2 requirements of the EN1317-2 standard as well as the highest snow-plough resistance class 4 of the EN1317-5.
By utilising the advanced properties of modern high-strength steel, SSAB was able to reduce the cost and improve the impact containment of its side barriers.
The side barrier W230 is delivered perforated, hot-dip galvanised and with accessories. Rail sections can also be delivered bent. Curved sections for the W230 are available with an angle of 45° or 90°. The standard rail delivery length of the W230 barrier is 12 m and the standard post spacing is 4 metres.
Structures requiring additional protection, such as bridge columns and passageways along the road, can be shielded by replacing the W230 side barrier with the completely compatible W230/4 side barrier using one or two metre post spacing.
Galvanisation according to the Finnish Transportation Agency's type drawings TIEH TY3/51 and Ty3/52:
•The minimum local zinc layer thickness of guardrails must be 75 μm.
•The minimum local zinc layer thickness of fasteners is 50 μm.
The most common barrier type in Finland is the W230/4 side barrier, which is defined in type drawing TY3/51 of the Finnish Transport Agency. The barrier system is available either CE-compliant, i.e. with a reinforced splice, or with a standard splice. The barrier is compliant with the containment level N2 requirements of the EN1317-2 standard as well as the highest snow-plough resistance class 4 of the EN1317-5. The barrier has been tested and approved with post spacing of 1, 2 and 4 meters.
SSAB's new side barrier SSAB W230 is completely compatible with the W230/4 side barrier, allowing customers to replace old W230/4 barriers with the safer and more economical SSAB W230 barrier.
