和河南彩钢厂订货与要注意什么？

至于向河南彩钢厂订货，我们都会问需要注意什么。订购时，请确认以下项目，以便选择适合最终用途的产品。
产品名称及规格
河南彩钢厂订货订购时，选择适合最终用途的规格尤为重要。另外，在普通钢板中可以选择的产品牌号有很多种。订购时请咨询负责人。
表面处理
根据后处理方法和最终产品使用条件，请在我们的列表中选择合适的表面处理方法。
后处理
河南彩钢厂订货无铬或无铬处理可有效防止镀锌钢板表面白锈
涂层数量
请根据目标耐久期、最终产品使用条件、加工方法等条件，选择合适的涂装量。如果环境容易腐蚀，建议采用厚涂层，建议采用薄涂层，以提高可加工性和焊接性。
上油
河南彩钢厂订货油量可根据客户的使用情况选择。但是，当同时订购未经处理和上油的钢时，会产生白锈。
大小
尺寸对客户的实际产量和加工性能有很大的影响。如果您的尺寸要求比目录中的生产范围更严格，请在订购前联系负责人。
选择dge
根据产品的使用条件，可选择铣边或切边。如果我们的产品边缘没有客户要求的附加工艺，而是直接成为最终产品的边缘，建议使用slitedge。
焊接部
线圈状态下的产品将产生酸洗焊件和镀锌焊件的混合物。焊接部位虽小，但硬度高，厚度大。因此，如果很难排除客户，请在订购时选择“请勿混入”，公司将采取相应措施。但是，在这种情况下，采购订单可能会受到限制。
包装
根据运输和储存的方法，可以选择包装形式，但如果选择裸包装，公司不能保证与白锈有关的质量问题。

As for ordering with steel mills, we all ask what we need to pay attention to. When ordering, please confirm the following items in order to select products suitable for end use.

Product name and specification
When ordering, it is particularly important to choose the specifications that are suitable for the end use. In addition, there are many kinds of products grade that can be selected from the general steel plate. Please consult with the person in charge when ordering.
surface treatment
According to the post-processing method and final product use conditions, please select the appropriate surface treatment method on our list.
Post processing
Chromium or Cr free treatment can effectively prevent white rust on the surface of galvanized steel sheet
Coating quantity
According to the target durability period, final product service conditions, processing methods and other conditions, please select the appropriate coating amount. If the environment is easy to decay, thick coating is recommended, and thin coating is recommended for processability and weldability.
Oiling
The amount of oil can be selected according to the service conditions of customers. However, white rust will occur when ordering untreated and oiled steel at the same time.
size
Size has great influence on the actual yield and processability of customers. Please contact the responsible person before ordering if you have more stringent size requirements than the production range in the catalogue.
Select dge
Milledge or slitedge can be selected according to the service conditions of the product. If the edge of our products does not have the additional process required by customers and becomes the edge of the final product directly, slitedge is recommended.
Welding department
The product in coil state will produce the mixture of pickling welding part and galvanizing welding part. Although the welding part is small, it has high hardness and thick thickness. Therefore, if it is difficult to remove the customer, please select "do not mix in" when ordering, and the company will take corresponding measures. However, in this case, the purchase order may be restricted.
packing
According to the method of transportation and storage, the packing form can be selected, but if the naked packing is selected, the company can not guarantee the quality problems related to white rust.
