When clients ask, "How much does a spherical space frame cost?", there is rarely a single fixed answer.
For quotation engineers, pricing a spherical space frame structure depends on multiple technical and project-related factors.
For quotation engineers, pricing a spherical space frame structure depends on multiple technical and project-related factors.
Due to the structural complexity and customization requirements of spherical space frame projects, the final quotation is influenced by design, materials, processing, installation, and long-term maintenance considerations.
Below, we explain the key factors that affect the price of a spherical space frame, helping buyers better understand cost composition and make informed decisions.
1. Material Type and Steel Grade
Different projects require different materials, which directly affect pricing.
Common materials used for spherical space frames include:
- Q235B steel – cost-effective for standard projects
- Q345B steel – higher strength, suitable for large-span structures
- Stainless steel space frames – corrosion-resistant, premium cost
In addition to steel grade, pipe diameter, wall thickness, and specifications also have a significant impact on the final price. Higher strength and thicker materials naturally result in higher costs.
2. Fabrication and Processing Quality
For projects involving processing-only services, fabrication costs are a major component of the quotation.
These may include:
- Precision cutting and welding
- CNC machining of spherical nodes
- Surface treatment (galvanizing, painting, anti-corrosion coating)
Higher fabrication accuracy and stricter quality standards will increase production costs but also ensure structural safety and long service life.
3. Transportation and On-Site Installation
Installation-related costs vary depending on the project location and scope.
Key factors include:
- Transportation distance (local, domestic, or overseas export)
- Loading, lifting, and unloading costs
- On-site installation labor for purlins, gutters, roofing systems, and accessories
For overseas projects, packaging, container loading, and international shipping must also be considered in the quotation.
4. Long-Term Maintenance and Supporting Materials
Due to the complexity of spherical space frame systems, follow-up maintenance and auxiliary materials also affect overall project cost.
These may include:
- Roof panels and bottom plates
- Ceiling systems
- Wall panels and insulation materials
- Flashing, edge trimming, drainage components, and accessories
Transportation costs for these materials are also factored into the total price.
5. Design Drawings and Project Requirements
All accurate quotations are based on approved design drawings.
Different structural spans, load requirements, and architectural demands will cause price fluctuations.
Different structural spans, load requirements, and architectural demands will cause price fluctuations.
Higher quality requirements, special structural forms, or customized designs will naturally result in higher costs.
