Tata Steel increases weathering steel availability

Posted on by in News

Responding to the increased demand for weathering steel hollow sections for use in small-to-medium sized projects, Tata Steel has launched its Enhanced Availability, which offers clients a select range of sizes in smaller amounts.

“There are over 300 unique cross-sectional sizes available in the Tata Steel Celsius® Weathering Grade range. While each of these has its place, we have found that there is a core of sizes which are particularly useful in smaller structures, such as footbridges and gantries,” says Tata Steel Marketing Manager Graeme Peacock.

“At the same time, these smaller structures generally require smaller amounts of each size and so we have recently introduced our Enhanced Availability.”

The Enhanced Availability offering is available across a range of square and rectangular section sizes in the Tata Steel Celsius® Weathering steel range. The sizes in this range have been specially selected to not only be popular, but to give a good range of structural capability.

The 18 Enhanced Availability sizes of Celsius® Weathering Grade cover the range from 60mm × 60mm × 6.3mm to 300mm × 300mm × 16mm for squares and 80mm × 40mm × 6.3mm to 400mm × 200mm × 16mm for rectangular hollow sections.

Depending on the size, length and production route, they are available with minimum order quantities between 1t and 5.5t, which in some cases, is equivalent to as little as three 12m lengths.

The full range of over 300 sizes of Celsius® Weathering Grade is still available from rollings, with minimum quantities between 15t and 30t, depending on the production route.

“We are sure that the Enhanced Availability range will prove particularly popular and will satisfy many requirements. Utilising these sizes at an early stage in engineering design will help to ensure availability in the right quantities when it comes to fabrication,” says Dr Peacock.

Full details of Celsius® Weathering Grade, including the Enhanced Availability sizes, are available in a new, updated datasheet which can be downloaded from
