CORE ADVANTAGES OF SPACE GRID STRUCTURES
Ultra-Light & Highly Transparent
Only 1% the weight of glass, with up to 95% light transmittance.
No need for artificial lighting during the day—spaces remain bright and open. The extremely lightweight material enables large-span structures without visual or spatial heaviness.
High Durability
25–30 year lifespan with excellent UV resistance.
No need for frequent replacement. Stable performance under sun, rain, and outdoor conditions offers peace of mind.
Self-Cleaning & Eco-Friendly
Smooth surface repels dust and is cleaned naturally by rain.
Minimal maintenance is required, keeping the roof clear and bright year-round.
Flexible Design
Supports air cushions, single-layer, or multi-layer tensile systems.
Ideal for large, column-free spaces like stadiums or arenas, and allows for creative, modern architectural forms.
