The purpose of this guide is to explain, in terms of modern
concepts, the basic requirements for protecting structural
steel with paint and metallic coatings, the systems commonly
used and their significance in relation to the protective
properties required. The emphasis is on the protection of
onshore structures, such as buildings, bridges, factories, and
industrial plants in which the process environment contributes
to the corrosion hazard.

Introduction

The purpose of this guide is to explain, in terms of modern
concepts, the basic requirements for protecting structural
steel with paint and metallic coatings, the systems commonly
used and their significance in relation to the protective
properties required. The emphasis is on the protection of
onshore structures, such as buildings, bridges, factories, and
industrial plants in which the process environment contributes
to the corrosion hazard.

Reference is made to appropriate standards which deal with
alternative protective systems in detail. These documents are
a very valuable source of information and it is recommended
that they should be consulted freely at an early stage in the
selection of a protective coating.

Emphasis is given to the important influence of application
methods on the efficiency of the protection achieved, and on
the need for strict inspection procedures. Guidance is also
given on procedures to be used when drafting specifications,
and on the health and safety and environmental protection
requirements to be observed.
