What are the common models of weather-resistant boards?

The models of weather-resistant boards are constantly improving as their uses continue to be enriched. So far, the models of weather-resistant boards have reached more than a thousand. Among these many models, they can be divided into three types: medium, low and high. Each type has different purposes and has its own price. At this time, we should continue to pay attention to each price trend and matching models. Today I will introduce to you the relevant weather-resistant board models:

Weathering board 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.

1. Common weather-resistant board models include: Q235NH, Q345NH, Q275NH. The reason is that many of these steel models are made directly from ordinary stainless steel blast furnace steel with some weather-resistant elements added thereto. The corrosion resistance of this kind of weather-resistant steel plate is only 1.5-3 times that of ordinary stainless steel plates. It is not durable, has strong rust loss, and lacks strength. The iron-making blast furnace is made from iron ore and is refined only once, so there is a lot of residue and it is difficult to achieve better quality.

2. Medium weather-resistant board models include: B480 and SPAH. Since it is a steel plate for shipping containers, its design needs to be sprayed and should not be used completely naked. These two types are medium weather-resistant steel material types, mainly used in train truck box cards, and their corrosion resistance is 3 to 5 times that of ordinary stainless steel. However, because the demand of shipping container factories is very large, they usually order directly from manufacturers instead of purchasing through the market. Therefore, many of the SPAH and B480 currently circulating on the market are divided into contracted products and defective products.

3. High-end weather-resistant board models include: 09CUPCRNIA. This steel model is a steel model introduced from the United States, which is also the original brand product of CORTEN-A, which is commonly known as CORTEN-A. It implements standards close to the United States.
