Zigong Lantern Fabrication Process – Six-Step Workflow

Overview

The Zigong lantern fabrication process is a centuries-old craftsmanship tradition that transforms raw materials into illuminated works of art. Recognized as an intangible cultural heritage, this six-step workflow combines engineering precision with artistic expression — from initial concept to final installation.

For Chinese Lanterns used in outdoor Event Decorations, the fabrication process ensures that each display meets structural safety standards, aesthetic quality requirements, and weather resistance specifications. This guide documents the complete six-step workflow as defined in DB51/T 2939-2022, providing event planners and procurement managers with a clear understanding of how custom lanterns are made.

The Six-Step Fabrication Workflow

The Zigong lantern fabrication process consists of six distinct steps, each with specific techniques, quality requirements, and responsible craftspeople.

Step 1: Design and Drawing

The process begins with the design phase, where concepts are developed into technical drawings. Per DB51/T 2939-2022 §5.2.1, design and drawing includes:

• Design concept development: Creating the artistic vision based on project requirements

• Technical drawing production: Generating scale drawings with dimensions, materials, and structural details

• Design specification: Documenting the creative concept, material requirements, and construction methods

The design phase ensures that the final product meets both aesthetic and functional requirements before fabrication begins.

Step 2: Enlargement and Layout

Once design drawings are approved, the patterns must be scaled up to full size. Per DB51/T 2939-2022 §5.2.2, the enlargement process includes:

• Full-size pattern layout: Scaling the design to actual dimensions using a grid system (typically 1:1 ratio)

• Part marking: Identifying and labeling all structural components

• Material estimation: Calculating required materials based on the full-size pattern

This step is critical for ensuring that all components fit together correctly during assembly.

Step 3: Frame Fabrication

The frame provides the structural support that determines the installation's strength and shape. Per DB51/T 2939-2022 §5.2.3, frame fabrication includes:

• Wire and rod preparation: Cutting metal components to specified lengths

• Frame assembly: Welding or tying metal components according to the pattern layout

• Structural reinforcement: Adding cross-bracing and support elements as required

• Corrosion protection: Applying anti-rust treatment to the steel frame

As covered in our Corrosion Protection for Outdoor Light Steel Structures guide, proper frame treatment is essential for outdoor longevity.

For large installations, structural engineering standards must also be considered. Refer to our Structural Engineering for Large Light Installations article for detailed specifications.

Step 4: Electrical Installation

The electrical system brings the lantern to life. Per DB51/T 2939-2022 §5.2.4, electrical installation includes:

• Wiring layout: Routing electrical cables within the frame structure

• Fixture installation: Mounting LED lights or other lighting elements

• Connection and testing: Wiring connections and electrical safety testing

• Mechanical integration: Installing moving parts or interactive elements (where specified)

Electrical installation must comply with local safety codes and international standards (IEC/EN/UL).

Step 5: Fabric Pasting and Decoration

This step is where the lantern takes on its final appearance. Per DB51/T 2939-2022 §5.2.5, pasting and decoration includes:

• Fabric selection: Choosing the appropriate fabric type for the design

• Cutting and preparation: Cutting fabric panels according to the pattern dimensions

• Pasting: Applying fabric to the frame using the techniques covered in our Pasting Techniques for Custom Light Fabric guide

• Color and pattern finishing: Painting, trimming, and final surface detailing

For fabric selection guidance, see our Fabric Comparison for Custom Lanterns article.

Step 6: Assembly and Commissioning

The final step is on-site assembly and commissioning. Per DB51/T 2939-2022 §5.2.6, assembly and commissioning includes:

• On-site assembly: Installing the lantern components in their final location

• Commissioning: Testing all electrical and mechanical systems

• Adjustment and optimization: Fine-tuning the display for optimal performance

• Final inspection: Conducting a complete inspection and handover to the client

This step ensures that the installation is safe, functional, and visually correct before the event begins.

Quality Control and Quality Standards

Throughout the fabrication process, quality control checks are performed at each step to ensure consistency and craftsmanship. Per DB51/T 2939-2022, the following quality standards apply:

• Materials inspection: Verifying that all materials meet specified requirements

• Dimensions: Checking all dimensions against the design drawings

• Surface quality: Ensuring that fabric surfaces are smooth, wrinkle-free, and clean

• Electrical safety: Testing all circuits, grounding, and safety devices

• Structural integrity: Confirming that all welds and connections are secure

Conclusion

The Zigong lantern fabrication process is a six-step workflow that combines traditional craftsmanship with modern engineering. Each step — from design and drawing through assembly and commissioning — requires specialized skills, careful quality control, and adherence to established standards.

For event planners, understanding this process helps in specifying requirements, evaluating fabrication proposals, and ensuring that the final installation meets both aesthetic and safety expectations.
