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.
