Manufacturing & Process

Craftsmanship & Technology: The Making of a HaoHang Greenhouse

Material Sourcing

“We source high-tensile Q235 steel and ultra-clear float glass from certified mills. Every batch undergoes rigorous chemical composition testing to ensure it meets our strict durability standards.”

Precision Fabrication

“Utilizing state-of-the-art CNC roll-forming machines, we achieve a manufacturing tolerance of ±0.1mm. This precision ensures that every component fits together perfectly during installation, saving you time and labor costs.”

Hot-Dip Galvanization

“Our frames undergo a full hot-dip galvanization process at 450°C. This creates a metallurgical bond that protects the steel from corrosion for decades, even in highly humid coastal environments.”

Quality Control

“Before packing, every connector, every sheet of glass, and every motor is inspected by our QC team. We follow the ISO 9001 quality management system to guarantee that what leaves our factory is flawless.”

A Global Footprint: Adapting to Every Climate

“HaoHang greenhouses are not just built to standard; they are built to location. Our engineers customize every project based on local environmental data.”
