Precision, performance, and lasting reliability — all in one integrated solution.
Alu Steel provides state-of-the-art vertical powder coating systems designed to meet the most demanding standards in aluminium finishing. Developed in collaboration with trusted industrial partners, our systems combine advanced materials, intelligent engineering, and digital monitoring to ensure consistent, high-quality results for extrusion profiles of every complexity.
Constructed from pure white A-grade PP corrosion-resistant plates, the coating chamber features a patented non-joint technology that ensures a smooth, seamless surface. This design not only provides a sturdy and long-lasting structure, but also maintains a clean and elegant appearance, ideal for controlled production environments.
The anti-static welded side panels effectively prevent powder build-up and loss, minimizing maintenance requirements and extending system lifespan.
Our segmented intelligent ventilation combined with optimized spray-gun distribution supports up to 36 spray guns in a single chamber. This configuration guarantees uniform coverage, reduces overspray, and enhances transfer efficiency, even on profiles with complex geometries.
The system integrates a large cyclone recovery unit with filter core filtration, ensuring optimal powder recovery and a clean working environment.
Key technical highlights:
Electrostatic PP board with integrated structure for improved insulation and durability
High-capacity powder recovery with cyclone and baking varnish surface treatment
Integrated safety inspection and explosion-proof devices for maximum operator protection
The linear fully automatic slow-speed steering mechanism allows for fine adjustment of spray angles, ensuring every section of the profile is perfectly coated.
A 90-cm extended secondary hook design, together with an automatic hanger cleaning device, minimizes powder adhesion and reduces cleaning downtime — increasing overall production efficiency.
The oven includes a waste heat recovery system and a low-ammonia energy-saving burner, lowering operational costs and environmental impact. Multiple safety systems — including air curtain water spray, lint treatment, and a top-mounted fire hose — guarantee secure and stable operation under all conditions.
Each installation comes with a Chengde Guangda chain conveyor system, featuring:
Robust design with 80 kg single-point bearing capacity
Integrated track, refueling, and drive mechanisms for smooth and continuous movement
To further enhance productivity, the system offers real-time data monitoring via a synchronous dashboard and cloud storage platform. This enables continuous supervision of operational parameters and performance trends, supporting preventive maintenance and long-term process optimization.
