Steel Structure Acceptance Standards

Standards for acceptance of steel structure erection Not only ensures the quality of the project but also brings many practical benefits such as Cost savings, increase structural life and minimize problems arising during use. In particular, all criteria in the steel structure acceptance process must be strictly followed. Law on Standards and Technical Regulations of the State, to protect the interests of investors and ensure that the project meets the highest safety standards. Hai Long Construction Joint Stock Company is proud to strictly apply these standards, bringing peace of mind and sustainable value to every project.

2. Standards for Acceptance of Steel Structure Erection

Process steel structure acceptance is an important step to ensure the project meets the quality and safety according to the design. Hai Long Construction Joint Stock Company carries out the erection and acceptance of steel structures based on structural drawing , and detailed design drawing, while complying with specific construction regulations to meet the highest standards.

2.1. Basic Requirements for Acceptance

Steel structures after erection must fully meet the following criteria:

• Load capacity: Ensure the structure can withstand the calculated loads without damage.
• Intensity and distortion: The structure must be maintained stability, not deformed excessively under the influence of weather (rain, wind, temperature) and other factors anticipated during the period of use.

2.2. Fire Resistance

A mandatory standard in steel structure acceptance is the ability to direct fire resistance. The structure must be maintained. integrity , and load capacity within a specified period of time in the event of a fire, ensuring maximum safety for the building and users.

2.3. Corrosion Protection

Steel structure works need to apply measures anticorrosion effective, through protective coatings or anti-corrosion paints, to maintain the durability and life of steel in harsh environmental conditions.

3. Requirements for Steel in Steel Structure Erection and Acceptance Standards

Steel is the core material that determines the quality and durability of a construction, so the requirements for steel in the process steel structure acceptance must be strictly adhered to.

3.1. Inspection and Classification of Steel Before Processing

• Before processing, steel must be Check specifications to ensure compliance with design specifications.
• Labels and markings: Steel must be labeled and marked with paint color separately for each type and arranged by cross section to avoid confusion. This is a mandatory requirement in the steel structure erection acceptance standards.

3.2. Steel Preparation and Storage

• Surface treatment: Steel must be straightening, clean grease, rust and impurities. The deflection and radius of curvature when bending must be within the allowable limits according to standards.
• Preserve:
  • Steel must be stacked securely in a warehouse with Covered.
  • If storing outdoors, cover with a anti-corrosion layer, tilted to ensure efficient drainage.

3.3. Transportation and Control of Welding Materials

• Transport: Use mesh or specialized racks to avoid steel deformation during transportation.
• Welding material:
  • Welding rod, welding wire , and welding flux must be tested according to current technical standards and drying according to the appropriate mode for each type.
  • The amount of welding material after drying can only be used within for 2 hours to ensure weld quality, avoid affecting the durability of steel structures.

4. Steel Structure Erection and Acceptance Procedure

The Franchising Process steel structure acceptance is the final step to ensure the quality and safety of the project after erection.

Step 1: Check Steel and Welding Materials

• Verification origin, label, color marker , and Quality Certificate of steel plates, steel wires, bolts and welding materials. This is an important step to ensure that the materials meet the standards before being put into construction.

Step 2: Material Testing

• In addition to visual inspection, steel samples must be taken for physical testing (strength, ductility, etc.), confirm that the material fully meets the technical requirements in the design.

Step 3: Check the Assembly of the Blank

• Evaluate the cutting and assembly process, including length, width, thickness, then make a detailed report and send it to the technical acceptance unit to confirm the accuracy.

Step 4: Check Additional Details

• Control of auxiliary parts and supporting equipment such as wiper blade, automatic welding machine. In particular, check weld by method magnetism , and supersonic to ensure no defects.

Step 5: Surface Check

• Before painting, the steel surface must be thoroughly cleaned. When inspecting, it is necessary to ensure that the surface is free of color bleeding, scratched or any damage that affects the quality.

Step 6: Check the Protective Paint Coating

• Check the two coats of paint carefully: anti-rust paint , and Finished paint, ensuring uniform coverage, effective corrosion resistance and meeting aesthetic standards.

Step 7: Record Data and Results

• After completing the above steps, proceed data entry, align product parameters and prepare summary reports, confirm that the steel structure meets standards for handover.

Each stage in this process is closely monitored, accompanied by detailed and accurate reporting, ensure the process steel structure acceptance transparent, bringing sustainable and safe projects to customers.
