What is the difference and connection between weatherproof steel plate and ordinary steel plate

Weather-resistant steel plate is an important type of steel plate, under normal circumstances, its role is relatively large, for the use of weather-resistant steel plate uses and various effects are generally concerned by us. What is the difference and connection between weatherproof steel plate and ordinary steel plate? We and you mainly introduce the difference and connection between weatherproof steel plate and ordinary steel plate:

First, the steel plate is not long rust link, the human eye can not distinguish between weather-resistant steel plate and general heat-tied steel plate. 1, must refer to the steel mill's warranty, the warranty as far as possible to require the dealer to produce the original of the steel mill seal, in order to prevent the store to be filled with inferior. The common materials of weathering steel are saddle steel or Shougang's 09cupcrnia, B480GNQR, etc., and the general hot-binding steel plate material is Q235B, SPHC, etc. 2, show the sample to a technical professional third-party testing organization to detect whether the metal composition is matched warranty.

Second, in the long rust stage of the steel plate, the weathering steel has just begun to grow small rust points, the rust points of the general steel plate are more loose, and some rust solutions are poor and even rust skin appears.

Third, the second stage of steel plate long rust, weather resistant steel plate rust water less, the rust point is small and thick; The rust water of the general steel plate is more, and the rust point is very thin and sparse; The rust column and tears of the general steel plate are serious, and the bottom of the product workpiece has a black sign.
