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.
