New structural steel tube from Tata Steel

Tata Steel has launched Celsius® 420, a stronger hot-finished structural steel hollow section that reduces the weight of mechanical products and can speed up the construction of new buildings.

This next-generation in hot finished structural steel, developed in conjunction with construction customers primarily for use in applications where structural performance at minimum weight is required, Celsius® 420 represents innovative advances in steel manufacturing.

Tata Steel Chief Commercial Officer in Europe Henrik Adam said: “Our Celsius® range is already very well established in the structural hollow sections market. But we know our customers are constantly on the look-out for new materials with enhanced properties, which is why we focus so much on innovation to develop next-generation products.

“In Celsius® 420 we’re bringing to market an entirely new range of hot-finished hollow structural sections that we think is in a class of its own.”

Tata Steel says the steel used to make Celsius® 420 hollow sections has a high yield strength (420 megapascals), which enables structural engineers to reduce the weight of the structural hollow sections they use by up to 17%.

The chemical properties of Celsius® 420 steel ensure it can be easily welded, despite its additional strength. This property – unique in high-strength tube products – means high-strength structures can be fabricated without changing standard weld procedures.

Tata Steel Head of Marketing, Construction & Infrastructure for European operations Jonathan Clemens, said: “Being a hot-finished welded product with added strength, Celsius® offers customers big advantages through lower material costs, good weldability and improved performance because of the high degree of uniformity in wall thickness.”

The Celsius® 420 range of circular, rectangular, square and elliptical hollow sections is now in production and available to the market. The sections are made from strip produced at Tata Steel’s plants in south Wales, which is formed into hot-finished tubes at the company’s Hartlepool and Corby mills in the UK.
