KR-PT-3070 Steel Structure Automatic Painting Line (3-12m Members) | Kasry, Dezhou, China

The KR-PT-3070 is an automatic painting line developed specially for steel structure fabricators. Members enter the line and are painted automatically, with the spray program generated from a 3D scan of the workpiece rather than programmed by hand. Kasry lists it under the names "H Beam Spraying & Painting Production Line" and "Steel Structure Automatic Painting Line".

It has 6 spray guns above the workpiece and 6 below, 12 in total, arranged around the member so a single pass paints it without turning it over. Each gun's position is controlled through the full range of angles to give a uniform paint thickness, and the thickness is adjustable. Spray painting takes place in a fully enclosed booth, with an interface reserved for VOC treatment, so workers stay away from the painting environment.

After spraying, the member passes through an intelligent temperature-controlled drying room, which dries the paint film quickly regardless of weather. Once the surface is dry, components can be hoisted off the line straight away. The line takes water-based or oil-based paint and can be dried by steam or electricity.

Why Choose an Automatic Painting Line?

Painting large steel members by hand is slow, uneven, and exposes workers to paint and solvent. It's also dependent on weather if done outdoors. An enclosed automated line addresses all of that.

• No manual programming. 3D scanning components generate the processing codes automatically.
• Even coating. Twelve guns with full-angle position control give uniform thickness, and the thickness can be adjusted.
• No turning. The member is painted on all sides in one pass.
• Weather-independent drying. The temperature-controlled drying room means output isn't held up by ambient conditions.
• Cleaner and safer. Enclosed painting with VOC treatment keeps workers away from the spray area.

Frequently Asked Questions

What does this line do?
It automatically paints steel structure members, using 12 spray guns in an enclosed booth and a temperature-controlled drying room.

How does it know where to spray?
3D scanning components generate the processing codes automatically from the shape of the member.

How long can the members be?
From 3 to 12m.

Does the member need to be turned over?
No. With 6 guns above and 6 below, it's painted on all sides in a single pass.

What paint can it use?
Water-based or oil-based paint.

How is the paint dried?
In an intelligent temperature-controlled drying room, using steam or electricity, so drying isn't affected by the weather.

How much space does it need?
The covered area is 64.5m × 11m.

Is financing or staged payment available?
Yes. A deposit secures your order and begins production, with the remaining balance due only once your machine has been built, inspected, and is ready to ship.

Should I buy new or used?
This line is available new, built to order.
