Structure & Craft: The main body adopts a combined system of large-span steel trusses and steel frames. Steel trusses act as the primary load-bearing components, enabling large-span column-free spaces, while box columns and H-shaped steel beams form a stable framework. All components are precisely prefabricated in the factory and then quickly assembled on-site via high-strength bolts or welding, ensuring efficient and eco-friendly construction.
Appearance Features: The buildings feature a multi-story modular layout, with light gray facades and glass curtain walls, and most roofs are equipped with photovoltaic panels or metal roofing. The overall lines are simple and modern, with well-planned roads, greenery, and water systems in the park, balancing practicality and ecological aesthetics.

Structure & Craft: The main body uses box-shaped steel columns and H-shaped steel beams as the basic frame, and cooperates with large-span steel trusses to realize large bay and column-free office space, improving the flexibility of internal layout. All components are precisely prefabricated in the factory and then assembled on-site with high-strength bolts, ensuring efficient construction and a short cycle time.
Appearance Features: The building is a high-rise slab design, with a facade of white dry-hanging stone and blue decorative lines, matched with large-area glass windows. The overall style is simple, modern, and transparent, meeting the image and lighting needs of commercial office buildings.

Structure & Craft: The main body adopts a combined system of large-span steel trusses and steel frames. As the core load-bearing component, steel trusses enable an extra-large span column-free production space to accommodate large industrial equipment and process flow requirements. Supporting facilities such as chimneys and auxiliary workshops also adopt steel structure design. All components are prefabricated in the factory and assembled on-site, ensuring efficient construction and strong stability.
Appearance Features: The main workshop is a multi-story large-span design, with a wavy metal roof and lighting strips that balance mechanical performance and modern aesthetics. The industrial park is equipped with office buildings, storage tanks, chimneys, and other facilities, surrounded by lush greenery, reflecting the ecological concept of environmental protection industry.

Structure & Craft: The main body uses heavy box-shaped steel columns and H-shaped steel beams as the basic load-bearing frame, and cooperates with large-span steel trusses to realize large bay and column-free floor space, improving the flexibility of internal layout and lighting efficiency. All components are precisely prefabricated in the factory and then quickly assembled on-site via high-strength bolts or welding, ensuring efficient construction and a short cycle time.
Appearance Features: The building is a high-rise frame structure, with a dark gray exposed steel structure frame on the facade. Safety protection and working platforms are set between floors, presenting a tough industrial style and showing the mechanical beauty and construction status of steel structure buildings.
