British Steel has unveiled another new product for the construction market – weathering steel structural sections.

Self-protecting, durable and attractive, weathering steel is ideal for a whole range of outdoor structures in exposed locations including bridges, buildings and catenary gantries on railway lines.

The steel’s corrosion rate is so low that structures fabricated from unpainted weathering steel can achieve long lifespans – in some cases up to 120 years – with only minimal maintenance.

British Steel Commercial Director, Construction, Ben Cunliffe, said: “Weathering steel is another superb example of our commitment to delivering quality products and services through rigorous research and development.

“It is a high-strength, low alloy steel that defends itself from corrosion by forming a protective oxide patina (layer), eliminating the need for paint or other protective coatings. This makes weathering steel an attractive and economic solution for many structures.”

Weathering steel offers significant advantages over other metals for structures that are exposed to the elements:

Low maintenance: ideal for bridges and structures where access is difficult or dangerous.

Cost reduction: no need for protective painting and low maintenance reduces associated costs.

Environmental benefits: no volatile organic compounds from paint or disposal of blast-cleaning debris from future maintenance.

Attractive appearance: mature weathering steel often blends pleasingly with the environment, changing and improving with age.

Speed of construction: without site painting operations, overall construction time is reduced.

Enhanced safety: painting issues are eliminated and future maintenance risks are minimised.
