To buy a steel fire door that meets national standards, you need to follow these steps:

Step 2: Determine the needs
Determine the type, specification, size and other special requirements of the required steel fire doors, such as fire rating, waterproof performance, etc. according to the actual needs.
Step 3: Choose the right manufacturer or supplier
Look for experienced and reputable manufacturers or suppliers. You can filter the suitable suppliers by searching the Internet, referring to the recommendation of friends or peers, and so on. At the same time, you need to pay attention to whether the supplier has the appropriate production license certificate as well as national standardization certification and other relevant qualifications.
Step 4: Conduct compliance testing
Provide product compliance test reports at the selected supplier. These reports should contain data on the product's fire performance indicators, material composition, strength tests, etc. to ensure that the purchased steel fire doors meet the requirements of national standards.
Step 5: Negotiate contract details

Step 6: Payment and acceptance
According to the contract, pay for the goods, and acceptance inspection after receiving the goods. In the acceptance process, it is necessary to pay attention to check whether the appearance, size, installation fittings, signs and labels of the steel fire doors meet the requirements of the contract, and carry out the corresponding test to check whether the functional performance of the steel fire doors meets the national standards.
Step 7: Installation and maintenance
Ask the professional construction team to install the steel fire doors and conduct acceptance with the supplier after the installation is completed. In the process of use, you need to regularly maintain and repair the steel fire door to keep it in normal use.
