Standard specification for acceptance of light steel keel

1）、 Quality requirements
1. The material of light steel keel should comply with the specified material standards and technical requirements.
2.The assembly, installation, and fixation of light steel keel should comply with relevant national standards and technical requirements.
3. The surface of the light steel keel should be smooth and even, without obvious defects such as unevenness, damage, and rust.
4. The surface of the light steel keel should be free of cracks, cracks, and other defects, and the structure and connection should be firm, without obvious deformation, distortion, and other defects.
2）、 Dimensional requirements
1. The size of the light steel keel should meet the requirements of the design drawings, and its dimensional tolerance should not exceed the allowable deviation range specified by national or industry standards.
2. The length of the light steel keel allows for a certain tolerance, which should be controlled within ± 5mm.
3. The cross-sectional shape and size of the light steel keel should meet the design requirements and industry standards, and there should be no obvious deviation between different parts.
3）、 Surface quality
1. The surface of the light steel keel should have no obvious scratches, scratches, or other damages.
2. The surface of the light steel keel should have no obvious deformation defects such as unevenness, distortion, etc. If any, it must comply with the allowable deviation range of national or industry standards.
3. The surface of the light steel keel shall not have coating defects such as missed coating, peeling, and scratching.
4）、 Processing requirements
1.The processing technology of light steel keel should be carried out in accordance with relevant national or industry regulations, with reasonable process and high machining dimensional accuracy.
2. The processing of light steel keel should meet the design requirements, and there should be no obvious deviation between different parts.
3. The processing technology of light steel keel should ensure the dimensional tolerance and surface quality requirements of the product, and ensure the performance and quality of the light steel keel.
The above are the standard specifications for the acceptance of light steel keel. We believe that by strictly following the standard operation, we can ensure the aesthetics and rationality of the structure, as well as the safety and quality of construction.
