1. Material saving: the most material saving method under the same load conditions, correspondingly, the material of the supporting structure can be reduced. 2. Less investment: save materials, save labor, save construction period, and avoid cleaning and maintenance. 3. Simple construction: the pre-installed support is reinforced with bolts, which can be completed by one person. 4. Time saving: the product does not need to be reprocessed on site, and the installation is very fast. 5. Durable and durable: hot-dip galvanized anti-corrosion treatment before leaving the factory, with strong impact and heavy pressure resistance. 6. Modern style: beautiful appearance, standard design, ventilated and light, giving people an overall smooth modern feeling. 7. Lightweight structure: less materials, light structure, and easy hoisting. 8. Prevent accumulation of dirt: no accumulation of rain, ice, snow and dust. 9. Reduce wind resistance: Due to the good ventilation performance, the wind resistance is small in case of strong wind, which reduces wind wave damage. 10. Good ventilation, lighting, heat dissipation, explosion-proof and anti-skid performance.
