I-Beam Painting Line

STA-3007L

Price: USD200,000~300,000

High Intelligence & Automation: Equipped with 3D scanning technology to automatically identify shapes; requires zero programming for operation.
Superior Quality & Efficiency: Delivers uniform coating and high-speed output. The
Eco-Friendly & Healthy: Low airflow requirements (approx. 10,000 m³/h) and effective odor control create a cleaner, safer workspace for employees.
Cost & Space Saving: Reduces paint wastage and features a compact footprint thanks to the reciprocating spray design.

Automated steel-structure painting equipment featuring 3D scanning for autonomous code generation and processing.

The Intelligent Steel Component Painting Line is a fully automated, smart spray-coating assembly line developed by our company specifically for steel structures. It offers high efficiency, superior coating quality, uniform thickness, material savings, and energy efficiency.

Utilizing an assembly-line workflow and advanced 3D scanning technology, the system intelligently identifies components and completes the painting process automatically without the need for programming. The reciprocating spray system occupies minimal space, and the exhaust treatment requires only a 10,000m³/h airflow, ensuring an odorless workshop and a cleaner, healthier, and more eco-friendly environment.

The "Spray-then-Bake" process allows components to be loaded for transport immediately after leaving the line, significantly shortening production cycles. The equipment requires only three operators who can be deployed after basic training, eliminating the need for highly skilled painters. It is a pioneering product in the light steel component painting industry.
