The promotion of prefabricated green building has become a general trend. From the national to local governments, the frequency of relevant policies to encourage the promotion of prefabricated buildings is not reduced, the path of encouraging the development of prefabricated buildings is gradually clear, and the standards to ensure the quality of prefabricated buildings are constantly improved.In many countries, green building has been developing rapidly under the condition of being conducive to the development of prefabricated steel structure buildings. 

We responds to the call of national policies, under the guidance of the general direction of the national green building strategy, relying on strong technical capital and advanced management mode, under the premise of safe production, improves the quality of steel structure processing products, and gradually shows its tension and demonstration.Now the country has paid more attention to green building than in previous years, so what is the basis for the evaluation of green building products?Many people are not very clear about the two concepts of green building and green building materials.In the face of green building materials and green building materials standards, many people feel confused about green building materials and green building materials standards.”If we follow this logic, all building materials products are not necessarily green buildings. 

In fact, the method of distinguishing green building materials and green building materials signs and certificates is very simple. As a customer, first of all, he has to go to the official website of the relevant national administrative authorities to verify whether he has the qualification of testing and certification and whether he has the qualification to issue the mark and certificate; secondly, he can learn about the technical testing level from the website of the relevant units that issue certificates and signs; and then from the network Search for its reputation and social influence, and then compare the price levels of relevant units to see if they are consistent. 

In order to promote the development of prefabricated steel structure construction industry and guide green building materials selection, the national building materials testing center has registered the certification trademark of “green building selected products” by the Trademark Office of the General Administration for Industry and Commerce of the people’s Republic of China.
