Coloured Coated Steel
The Construction Industry is supported by the manufacturing of
high quality, competitive products and by expert technical service.
Our service and quality commitment is based upon a policy of
working closely with our customers, applying quality assurance
practices to all our activities, and achieving technical excellence
through research, product development and capital investment.
The range of organic coated steels is a product of that
commitment.
HPS200 represents over forty years of experience in
manufacturing organic coated steels, in partnership with leading
paint manufacturers. These products have been tested and proven
at laboratory test sites around the world, and on over 750 million
square metres of roofing and cladding.
The premier product, HPS200 offers a written, transferable
Confidex® guarantee in the UK and the Republic of Ireland.
Steel as a Profile Material
Steel, with its combination of flexibility, durability, strength-to-weight
ratio and economy, is an ideal material for profiled cladding.
The steel substrates for organic coated steels in external
environments are Galvalloy (hot-dip coated with a eutectic alloy of
approx. 95% Zn, 5% Al, and other elements) and Galvatite (hot-dip
zinc coated steel). Galvalloy is the substrate for HPS200 and
Celestia. Galvatite is the only substrate for PVDF.
A structural grade of substrate giving a guaranteed minimum
yield strength of 220 N/mm².
Substrate designations are:
Galvalloy - S220GD+ZA (1995) from BS EN 10214
Galvatite - Fe E220 G from BS EN 10147
Coated Products
The customer can be certain that the product has been
comprehensively tested and evaluated by the extensive research
and development facilities of our suppliers.
These products have been developed over many years, for a
variety of applications, and therefore have different performance
characteristics. The descriptions that follow are aimed at
distinguishing those differences.
Pre-coated products for exterior roofing and cladding are
composed of a steel substrate having a metallic coating,
pre-treatment, and primer on both sides, with a paint topcoat on
the weatherside and a polyester coating on the reverse side
(commonly referred to as the backing coat). There are different
metallic and organic coatings for particular applications
Roofing & Cladding Products
Potential specifiers and users of these products should refer to the
exterior coatings table on page 140 for typical properties.
HPS200 by Corus
HPS200 is a premier pre-painted architectural product, tested in
the laboratory and on site in severe climates, for use worldwide.
Its tough, 200 micrometre (nominal thickness) coating system has
the unique Scintilla finish and is available in bright or subtle hues,
providing architects with an extensive palette of colours.
With its unique coating formulation, HPS200 is brand-marked to
protect specifiers from substitutes. Specifiers and building owners
also have the protection of our suppliers guarantee, which is a
written, transferable guarantee for HPS200 on buildings in the UK
and the Republic of Ireland.
200 Micron Plastisol
200 micron Plastisol is a 200 micrometre thick high performance
plastisol coating system with leather grain finish.
Specifiers and building owners also have the protection of a
suppliers guarantee, which is written guarantee on buildings in the
UK and the Republic of Ireland.
Celestia by Corus
Celestia is a metallic-finish cladding steel with a 120 micrometre
(nominal thickness) high performance plastisol coating.
The standard product has a high-performance polyester coating
on the reverse side. The metallic finish captures light and
movement, giving depth and life to cladding surfaces.
Colorcoat PVDF
PVDF has a smooth, 27 micrometre (nominal thickness) coating
system which offers excellent colour stability. The standard colour
range includes metallic silver. Whilst PVDF offers good corrosion
resistance in most environments worldwide, its durability is
generally less than that of HPS200.
Bright White Polyester
This has been developed specially for steel lining trays and panels.
With its good light-reflecting properties and its smooth, easy-toclean
surface, it provides an efficient and durable internal lining
system which should last the life of the building in normal,
controlled environments. A bright white finish and two pastel
shades offer architects a choice of interior effects.
