About us



DONGGE has been developing stainless steel structures since 2011, which are categorized into decorative support columns and load-bearing components.
Decorative support columns, replace glass ribs with stainless steel fin, offering durability, earthquake resistance, and decorative functions.
Load-bearing steel frame, replaces carbon steel structure and serves as the supporting structure of the building.It is characterized by its corrosion resistance, self-cleaning properties, and long service life.

High Precision and Demands:

Stainless steel structural can reach a full length of 20 meters, with linearity and flatness of ≤0.5mm/m, R-angle of ≤0.5mm, and for lengths within 18 meters, the linearity is ≤5mm.

Durability and Longevity: 

Stainless steel structures are renowned for their durability, requiring minimal maintenance for prolonged use. They can resist rusting, corrosion, and staining.

Strength to Weight Ratio: 

Stainless steel offers a high strength-to-weight ratio, meaning structures can be lighter while maintaining the same strength.


Stainless steel has a modern and sleek appearance. Its texture, patterns, and sandblasted surface effects are consistent, requiring no additional coatings or paint to maintain its look, enhancing the metallic feel of architectural structures and offering strong visual appeal.

Resistant to Various Weather Conditions: 

Stainless steel can withstand a range of weather conditions, from extreme cold to high temperatures, without compromising its structural integrity.


Stainless steel is 100% recyclable, making it an environmentally-friendly material choice.

Design Flexibility:
Due to its strength and malleability, stainless steel can be used for various architectural designs and shapes.
