Hempel has launched its new Hempadur
Avantguard 860 that uses innovative
organic, zinc-rich primer coating
technology.
Avantguard zinc-rich primers are said to
be ideal for harsh environments, such as on
bridges, offshore oil platforms and coastal
power plants, or any asset that faces humid
and aggressive atmospheres.
Hempadur Avantguard 860 is said to
offer the same anticorrosive performance
as zinc silicates with the same level of zinc
content, but without the usual drawbacks
– such as mud-cracking at a relatively high
dry film thickness.
Hempel said as a result of this
technology only a short, one-hour, overcoating
interval is required, there is no need
to apply a mist coat, and consequently there
is a boost to productivity.
Avantguard’s activated zinc-rich epoxy
primer coating technology incorporates
tiny hollow glass spheres and a special
proprietary additive called an ‘activator’.
Hempel said it is because of these
innovations that the coating provides
galvanic, barrier and inhibitor protection.
The galvanic protection increases the
zinc’s ability to carry the corrosion current,
even if the zinc particles are not in direct
contact, which is said to improve the steel’s
corrosion protection.
The coating’s hollow glass spheres
are also said to play a vital role in its
performance. Firstly, they block the spread
of micro-cracks, and contribute to the
coating’s low permeability, and secondly,
they actively inhibit corrosion.
A fully assembled single span footbridge
weighing 45t has been installed over the M20
in Kent during a night-time closure of the
motorway.
Fabricated and supplied by locally-based
Nusteel Structures, the steel bridge has been
designed for pedestrians, cyclists and
equestrians, and forms part of the ongoing
junction 10a improvement scheme.
The existing Highfield Lane bridge is
scheduled to be demolished next year,
following the installation of East and West
Gyratory Bridges which form the new junction
near Ashford. The new footbridge will then
open to the pubic later next summer.

Somerset steelwork contractor wins product award
Taunton Fabrications has won Willmott
Dixon’s Product Award at the contractor’s
recently held Wales & The West Supply
Chain Awards.
The award is given to a supply
chain partner that demonstrates an
obsession about quality of product,
embraces innovation in systems
and design, has an open and honest
approach to realistic workloads and
capabilities, and produces a defect free
product.
Commenting on the Aurora office
development in Bristol, where Taunton
Fabrications supplied a seven-flight
steel feature staircase, Andrew Daniel of
Willmott Dixon said: “Taunton provided
an outstanding service in pre-construction
and a defect-free product that is a
showpiece in the building which the client
is immensely proud of.”
Taunton Fabrications Managing
Director Jason Rigby said: “Project Aurora
was particularly challenging and involved
almost 100 pages of calculations, 300
hours of design, 350 drawings and 25t
of steel.
“To have designed, manufactured and
installed all of that work with no defects is
a credit to our staff.”

Design Manager; Chris Sampson,
Taunton Fabrications Senior Estimator;
