WF Installation Stages from Lifting to Locking in the Project

Wide Flange (WF) installation is a crucial stage in steel construction. WFs serve as the main structural element that supports and distributes the building's loads. Therefore, the installation process must be carried out in stages, precisely, and according to technical procedures to ensure optimal structural strength.

The following are the stages of WF installation in a project, from lifting to final locking.

1. Material and Work Area Preparation
Before lifting the WF, ensure:

• The WF dimensions and specifications match the structural drawings
• The material is not bent or damaged
• The work area is safe and ready for erection
• This stage is crucial to prevent errors from the beginning of installation.

2. Lifting the WF (Lifting)
The WF is lifted using a crane or lifting equipment with appropriate capacity. Lifting must be done with the correct lifting point to prevent the WF from bending or twisting in the air. The correct use of slings and other tools significantly impacts work safety and the condition of the material.

3. Initial WF Placement
After lifting, the WF is placed in its intended position, either as a column or beam. At this stage, the WF is usually still temporary and has not been permanently secured. The initial position must follow the axis, elevation, and orientation specified in the working drawings.

4. Alignment and Alignment
The WF is then adjusted so that it is:

• Plumbular (for columns)
• Parallel (for beams)
• Corresponding to the axis and elevation
• Alignment is performed using measuring tools such as a water level or other measuring instruments to achieve precision.

5. Temporary Locking
Once the WF is positioned correctly, temporary locking is performed using temporary bolts or tack welds. The purpose is to hold the WF from shifting during the installation of other elements.

This stage is important to maintain structural stability before permanent locking.

6. Installation of Permanent Connections
Permanent connections are made according to design specifications, either by:

• Bolted connections
• Welded connections
• A combination of bolts and welds

This process must be monitored to ensure the quality of the connection meets the required technical standards.

7. Final Locking and Inspection
The final stage is the final tightening of bolts or completion of permanent welds. Afterward, a re-inspection is carried out for:

• Flatness and alignment of the WF
• Connection quality
• Compliance with structural drawings
• The WF that has been final locked must not shift again.

The Importance of Proper Installation Procedures
Each stage of WF installation is interconnected. Skipping a step or performing it without precision can impact the strength and safety of the overall structure.

To ensure safe and standard WF installation, ensure you use SNI-compliant WF with the correct specifications.
