Prefabricated steel buildings are increasingly becoming the top choice thanks to their outstanding advantages such as construction cost optimization, shorten construction time and flexibility in design. However, construction quality is always a major concern for investors. Understanding that, Hai Long Construction Joint Stock Company brings a detailed article, fully answering about Standards for construction and acceptance of steel structures in pre-engineered steel building construction. Don't miss the important information below to ensure your project achieves optimal safety and sustainability!
1. What is Steel Structure?
Standards for construction and acceptance of steel structures is always the top concern when implementing construction projects, especially with pre-engineered steel buildings. Let's explore the concept and characteristics of steel structures with Hai Long Construction Joint Stock Company to better understand its important role.
Steel structure is a load-bearing steel frame system, made from high-quality steel, widely used in construction works. Especially, with large-scale projects such as Steel BuildingsSteel structures not only ensure durability but also provide flexibility in design and construction, meeting the strict technical requirements of every project.

3. Requirements for Steel and Welding Materials in Prefabricated House Construction
The quality of steel and welding materials plays a decisive role in the durability and safety of pre-engineered steel buildings. Therefore, strict compliance with technical standards in the construction and acceptance of steel structures is a factor that cannot be overlooked. Hai Long Construction Joint Stock Company always ensures the application of the following requirements to bring the project to optimal standards:
3.1. Requirements for Steel
- Technical inspection: Before processing, all steel must be inspected for technical specifications according to design drawings, ensuring that it meets load-bearing requirements.
- Classification and marking: Steel must be classified according to labels, marked with paint color separately for each type and arrange by cross section to avoid confusion.
- Surface preparation: Steel must be straightening, remove rust, grease and impurities. When bending, the allowable radius of curvature and deflection must comply with current technical standards.
- Preserve:
- Steel must be stacked securely in covered warehouses.
- If stored outdoors, it is necessary to protective coating, pad and tilt for effective drainage.
- Transport: Use Special price set to avoid steel deformation during transportation.
3.2. Requirements for Welding Materials
- CHeck quality: Before use, welding rod, welding wire , and welding flux must be tested according to current technical standards or specific regulatory conditions.
- Pre-welding treatment: Welding materials need to be drying according to the appropriate mode for each type:
- The amount of dried material used only within a production shift (for low carbon steel) or in two hours (for low alloy steel).
- Material selection: Welding rods, welding wire and flux must be selected based on tensile strength , and weldability of structural components. Flaked, dirty or damaged welding rods shall be completely discarded.
3.3. Protection of Steel Structures
Paint materials used to protect steel structures must comply with TCVN 8789:2011, ensuring corrosion resistance and maintaining long-term durability for the project.
With a deep understanding of steel structure acceptance standards, Hai Long Construction Joint Stock Company is committed to using the highest quality steel and welding materials, providing sustainable, safe pre-engineered steel buildings that meet all strict requirements of customers.
4. Steps for Quality Control in Steel Structure Construction
To ensure that pre-engineered steel buildings are of optimal quality, monitoring materials and construction processes is a key factor in steel structure acceptance standardsHai Long Construction Joint Stock Company applies a strict supervision process with the following steps:
4.1. Checking the Contractor's Steel Structure Construction Process
Evaluate the contractor's entire construction process, from material preparation to installation, ensuring compliance with design drawings and technical standards.
4.2. Inspection of Steel Structure Manufacturing Facility
Inspect production capacity at the manufacturing plant, including machinery, equipment and processing procedures, to ensure finished steel meets required quality.
4.3. Checking the Contractor's Quality Management System
Review the contractor's quality management system (QMS), including control procedures, technical documentation and certification records, to ensure consistency and transparency.
4.4. Supervision of Steel Structure Fabrication Process
Closely monitor each manufacturing stage, from cutting, welding, to assembly, ensuring steel components are manufactured accurately, without dimensional errors or defects.
4.5. Structural Testing Laboratory Supervision
Conduct experimental tests (such as strength tests, weld tests) to confirm the load-bearing capacity and safety of steel structures before erection.
4.6. Inspection and Acceptance of Manufactured Steel Structure Products
Carefully check completed steel components, compare with technical standards and drawings, to ensure products meet requirements before being delivered to the construction site.
4.7. Supervision of Transportation and Erection of Steel Structures
Control the transportation process to avoid deformation of components, and supervise the installation at the site, ensuring that joints, bolts and steel frames are firmly fixed according to design.
With a comprehensive monitoring process, Hai Long Construction Joint Stock Company is committed to providing pre-engineered steel buildings that meet standards and fully meet steel structure acceptance standards, bringing absolute peace of mind to customers.
5. Pre-Engineered Steel Building Construction Standards
Prefabricated steel houses are built based on the principle of assembly, requiring closely linked between steel structures to ensure durability and safety. Hai Long Construction Joint Stock Company always strictly adheres to the standards for construction and acceptance of steel structures, including TCXDVN 170:2007 is an important guideline to bring high quality and sustainable projects.
5.1. Basic Requirements in Construction and Acceptance
- Processing and assembly:
- Steel structures must be fabricated and assembled correctly. structural drawing , and detailed drawingSpecial components outside the general standards must comply with separate regulations.
- Apply mechanical method or large block to comply with approved construction methods and technological diagrams.
- Check and record: During the process of processing, assembling and acceptance, it is necessary to supervise the implementation. technology diagram , and construction methods. The test results must be fully recorded in construction diary.
5.2. Ensuring Load-bearing Capacity
Steel structures must meet design requirements for:
- Reliability, fatigue, stability , and deformation, ensuring optimal load-bearing capacity under all load conditions.
- Fire resistant: When exposed to direct fire, the structure must maintain bearing capacity , and integrity within the specified time.
5.3. Corrosion Protection
- Steel structures need to be corrosion protection according to the requirements in the design documents and current construction standards.
- Protective coating must be applied at factory or manufacturing plant, ensuring consistent quality and long-term effectiveness.
With extensive experience in the field of pre-engineered steel buildings, Hai Long Construction Joint Stock Company commits to carry out construction and acceptance of steel structures according to Steel structure acceptance standard TCXDVN 170:2007, bringing peace of mind and superior value to every project.
