What are the precautions in the use of weathering steel?

As the weathering steel has the characteristics of high-quality steel, such as strength and toughness, plastic ductility, forming, welding cutting, abrasion, high temperature and other characteristics of high-quality steel, at the same time, it has the corrosion resistance, life extension, thinning and consumption reduction, labor saving and energy saving. BBN summed up a few points of attention in the construction, I hope to help you.

Pay attention to the natural conditions of the site. Indoor, outdoor, inland, coastal, different locations in different areas of the air salt content and air humidity, sunshine, building shape and orientation will affect the growth rate and composition of rust layer of weathering steel, so it will show more or less uneven rust state. Attention should be paid to the uniformity of the color of the whole water intake and the uniformity of the lighting.

Avoid water accumulation. In the water environment, the rust layer is easy to layer corrosion, so the drainage design near the bottom of weathering steel should be paid attention to. For example, if the planting pool is made of weathering steel, attention should be paid to the filling height and internal drainage channel in the design, so as to avoid the pollution and corrosion of steel by mud water gushing out in rain.

The color reference of weathering steel sample is not good. Because it takes 6 months to 1 year from brand-new steel plate to the formation of stable and dense rust red protective layer in general natural environment (with rust promoter), it may be longer for some dry areas or indoor. And even if we want to produce a simple uniform rust yellow, it will take about a month. In this process, the color of components gradually transits from bright yellow, earth yellow, orange, orange red, reddish brown and brown.
