weathering steel plates is relatively hard. The various properties of weathering steel plates are relatively good, and they are very good in corrosion resistance and wear resistance. Its main components are
wear-resistant steel and atmospheric corrosion steel plates. The effect of ordinary steel plates is so-so.
Since the weathering steel plate needs to be rusted, the rusting is explained in stages. In the first stage, the steel plate is not rusted. The naked eye cannot distinguish between genuine weather-resistant steel plates and ordinary hot-rolled steel plates. You need to refer to the steel company's warranty book. Can also provide samples to professional third-party testing agencies. The second stage is long rust of steel plate. In the first stage, the genuine weathering steel begins to grow small rust spots. The rust spots of ordinary steel plates are relatively loose, and some of the rust treatment is poor or even rust.
The third stage is long rust of steel plate. In the second stage, the genuine weathering steel has less rust water, and the rust spots are smaller and denser; the ordinary steel plate has more rust water, and the rust spots are larger and thinner; There are signs of blackening at the bottom of the workpiece. The fourth stage is the long rust of the steel plate. In the third stage, the genuine weathering steel has a clear and dense rust core layer, and the rust spots are closely adhered to form a protective layer. Pieces of rust peeled off and rust was worn. Genuine weathering steel is biased towards reddish brown, and ordinary steel plates are biased towards dark black.
