1. Overview of Steel Structure Construction Methods
Steel structure construction is currently a superior choice in the construction industry, offering outstanding durability, long service life, and flexible adaptability for various types of projects. Compared to traditional materials like wood—which are costly, susceptible to termite damage, and deteriorate quickly under harsh weather conditions—steel structures stand out for their robustness, safety, and optimal load-bearing capacity.
In particular, projects using steel structures can effectively withstand harsh environmental conditions such as storms, floods, or earthquakes—something that wood or even reinforced concrete cannot always fully guarantee. With extensive experience as a general contractor, Hai Long Construction JSC is proud to provide high-quality steel structure construction solutions, ensuring sustainability and absolute safety for every project, from factory buildings and high-rise buildings to large-scale industrial facilities.
2. Steel Structure Construction Process
Steel structure construction requires a precise execution process, the use of modern equipment, and a highly specialized technical team. Hai Long Construction JSC applies optimal measures to ensure the schedule and quality for every project item.
2.1. Main Frame Erection for Factory Buildings
The main frame of a factory building consists of core components such as steel columns, trusses, and truss assemblies, which act as the primary load-bearing elements for the entire structure. The erection process is carried out sequentially as follows:
- Erecting the rigid bay:
- Use heavy-duty cranes to lift and precisely install the first 4 perimeter columns, creating a solid foundation for the factory frame.
- Deploy construction scaffolding at each perimeter column position, ensuring they are securely fixed with anchor bolts to increase safety and stability during construction.
- Installing the purlin frame:
- Use specialized lifting equipment to move the purlin frame into the design position, then secure it firmly with high-strength bolts.
- The entire process is strictly supervised to ensure the alignment between components, avoiding deviations that could affect the overall structure.
2.2. Truss Erection
The truss erection process is a critical step in steel structure construction, requiring precision and strict adherence to the sequence. At Hai Long Construction JSC, trusses are installed from the inside out, prioritizing starting from the bay with wind bracing (including column bracing and roof bracing) to ensure initial stability.
After installation is complete, each component is secured with straps wrapped around two points, approximately 1/4 of the length from the ends, combined with the use of high-strength bolts to increase rigidity and safety.
2.3. Completing the Bracing Truss
To ensure the steel structure achieves optimal rigidity, permanent cross-bracing cables for columns and truss beams are carefully installed and then secured with specialized bolts.
- Note: All installation positions must be pre-measured accurately based on technical drawings to avoid deviations and ensure the fit between components.
2.4. Installing Truss Frames and Purlins
The entire truss frame and purlins are installed onto the perimeter columns and interior columns according to the design. During this process:
- Adjust the column height, verticality, and the position of each component to match the technical drawings.
- Use anchor bolts to secure them firmly, then proceed to clean the surface and touch up any scratches or rough spots, ensuring aesthetics and corrosion resistance for the entire truss frame and purlins.
2.5. Erecting Gable Trusses
To construct gable trusses:
- Use specialized ropes to pull purlins onto the roof, then secure them with bolts to ensure durability and stability.
- Repeat this process until the entire gable truss beam is completed, ensuring a uniform and solid structure.
2.6. Completing Purlins and Bracing Members
- Use lifting equipment to move the truss beam web bracing onto the roof, while purlins are pulled up using ropes and secured with bolts.
- Simultaneously, complete the installation of permanent cross-bracing for the columns and truss beams of the bracing bay, ensuring the entire steel structure meets the highest technical standards.
With experience in executing a series of factory building and industrial projects, Hai Long Construction JSC is committed to providing safe, rapid, and high-technical-standard steel structure construction solutions.
3. Roof and Wall Sheeting Installation in Steel Structure Construction
After completing the steel structure frame, installing roof and wall sheeting is the final step to ensure the building is ready for use. Hai Long Construction JSC performs this process with maximum precision and safety.
3.1. Transporting Roofing Sheets to the Roof
Roofing sheets are lifted to the roof via specialized slide rails, ensuring accurate transport to the pre-determined roof purlin positions. This process saves time and minimizes construction risks.
3.2. Roof Sheeting Installation
Before installing the sheets, the construction team proceeds to:
- Install a safety cable system on the roof and prepare all necessary electrical equipment for construction.
- Note: The electrical system must be arranged to avoid direct contact with purlins and roof sheets to ensure occupational safety.
Next, each sheet is precisely positioned and installed according to the design, ensuring both technical durability and high aesthetics for the project.
3.3. Installing Wall Purlins, Gutters, Downspouts, and Wall Sheeting
- Erect a sturdy construction scaffolding system to support the installation process.
- Proceed to install all wall purlins, intermediate purlins, wall sheeting, along with accessories such as gutters and ventilators, ensuring a complete and synchronized structure.
3.4. Inspection and Handover of the Project
After completing the steel structure construction and sheeting installation, Hai Long Construction JSC performs:
- Comprehensive inspection: Thoroughly review everything from steel columns, truss frames, and anchor bolts to connections, ensuring no errors, however small.
- Handover: Transfer the completed project to the client, ready for use with optimal quality.
3.5. Warranty and Post-Construction Support
Throughout the steel structure construction process and after completion, Hai Long Construction JSC commits to:
- Regular supervision: Periodically check the progress and quality of the project.
- Customer care: Maintain continuous contact and support to ensure satisfaction and efficient operation of the project over the long term.
With a systematic steel structure construction process and dedicated after-sales service, we are proud to deliver sustainable, safe projects that meet all rigorous standards.
