Lambert, in Sustainability of Construction Materials (Second Edition), 2016. 6.4 Weathering steels. Weathering steels, sometimes referred to as high-strength low-alloy (HSLA) steels, are formulated to produce a dense, stable oxide layer that provides sufficient protection without the need for coating systems.This oxide layer results from the inclusion of alloying elements such as copper Weathering Steel Specifications & Benefits Central Steel Initial cost benefits:Cost savings from the elimination of any protective paint system may outweigh the additional material costs. For example, the cost of weathering steel has been shown to be approximately 5 percent lower than conventional painted steel alternatives in bridges using a HA Type 2 paint system.

A709 Grade 50W and Grade 70 HPS - 70W. This steel eliminates the need for painting because the steel weathers to form a protective patina, or thin layer of protective oxide coating, that prevents the steel from further rusting. Its slightly higher cost per pound than nonweathering
