When sourcing glamping domes, the structural integrity and material quality are paramount. Prioritize Hot-Dip Galvanized Steel frames with a diameter of at least 25mm to 32mm to ensure wind resistance up to level 10-12 (80-120km/h). For the cover, look for 850g/sqm PVC-coated polyester fabric that is UV-resistant, 100% waterproof, and flame retardant (DIN4102 B1/M2 standards). Additionally, ensure the dome includes a ventilation system (solar fans or mesh windows) to prevent condensation, which is a common issue in spherical structures.
