What are the common types of weathering boards?

The model of the weatherproof board with the continuous use of rich and colorful is also constantly sound, so far, the model of the weatherproof board has been more than a thousand, in so many models can probably be divided into medium, low, three types, each type is the main use of the difference, but also has its own price, At this point, it should be carried out again to care about each price and the matching model. Today I will introduce to you the models of the weathering board:

Weathering plate models mainly include: 05CuPCrNi-A, 09CuPCrNi-A, SPA-H, B480GNQR, Q400NQR1, Q450NQR1, Q550NQR1, Q700NQR1, Q235NH, Q295NH, Q355NH, Q460NH, Q295GNHL, Q345GNHL, Q460GNHL, Corten-A, COR-TEN,B450NQ,B460NQ,Q500NQ, NMIE0921, NM360, NM400Q450NQR1, etc.

First, the ordinary weathering board models are :Q235NH,Q345NH,Q275NH. The reason is that these many steel models are immediately manufactured from the general stainless steel sheet iron blast furnace steel to add a part of the weathering factor. The corrosion resistance of this weather resistant steel plate is only 1.5-3 times that of general stainless steel plate, which is not durable, strong rust removal, and insufficient compressive strength. Because the blast furnace is made of iron ore, it is only extracted once, so there is more residue and it is difficult to achieve better quality.

Second, medium weathering plate models are: B480, SPAH. Since it is a thick steel plate for shipping containers, its own design scheme must be sprayed and applied, and it should not be completely naked application. These two belong to the medium weathering steel plate raw material model, the key used in the train truck box card, the corrosion resistance of the general stainless steel plate 3 to 5 times. However, because the demand of Marine container plants is very large, they generally order immediately to manufacturers, rather than easy to buy according to the sales market. Therefore, many of the SPAH,B480 products currently in circulation in the market are classified into contract products and substandard products.

Third, high-end weathering board models are: 09CUPCRNIA. The steel model is a steel model introduced by the United Kingdom, that is, the original brand of CORTEN-A, which is close to the specifications of the British level.

Below is the international weathering plate model:

1, China's common weathering steel model: Q235NH, Q355NH, high weathering model: Q355GNH.

2, American standard: G3125 National Railway Bureau specification weathering steel has those models: 09CuPCrNi-AaccordingtoTB1979. Weathering steel ASTMA588Corten-A/B Marine container special weathering steel model: SPA-H, JIS specification.

3, European standard 10025-5:2004. Weathering steel models: S355J0W S355J2W, S355K2W, S355J0WP and S355J2WP.

4, Japanese standard JISG3114-2004 model of weathering steel, weathering steel plate material: SMA400AW/BW/the CW, SAM490AW/BW/the CW/SAM570W/P.
