Steel Structure Painting Questions for Heavy Component Lines

The line is developed for large and complex steel components. An automatic scanning system identifies each component's three-dimensional structure from all directions and prepares the painting process.

A fabrication plant should review its component range together with the available load-bearing brackets and chain-car specifications. Send component drawings, maximum dimensions, weight range, and expected daily quantity to Yeed Tech Co.,Ltd. so the transport arrangement and supports can be discussed.

The automatic 3D scanning system identifies the component structure in all directions before painting. This allows the process to account for the shape of a component with multiple faces or changing sections, supporting uniform coating across complex steel workpieces.

For a project review, provide representative drawings and mark the surfaces that require coating. These details help define how the scanning and spray process should address the component geometry.

Chain cars carry heavy steel structural components along a track. After painting and unloading, they return to their original position to continue transportation. The small cars can use different load-bearing bracket styles, while chain-car specifications can be selected for different component types.

A typical production cycle places a component on a suitable bracket, carries it through the painting area, unloads it after painting, and returns the chain car for the next movement cycle. Before ordering, send the component weight, support points, dimensions, and planned track arrangement for review.

The filtration section uses a two-stage design with a nine-grid spoiler and paint-blocking cotton. The paint-blocking cotton is made from multiple layers of glass fiber composite, with density increasing through its thickness. The material is designed for paint-mist purification and has high capacity, low cost, and flame-retardant properties.

These filtration details matter when planning the spray area and maintenance access. Include the coating process and planned production quantity in the project information so the filtration arrangement can be discussed with the line layout.

Drying uses a natural gas combustion furnace. A fan sends heated air into the drying chamber through a pipeline. An electric contact temperature sensor automatically adjusts furnace output, controlling the indoor temperature within a set range of 40 to 80°C.

The temperature can be adjusted according to the climate and coating properties. The process is described for surface drying with a single coating thickness of about 80 μm. Send the coating type, target coating process, component dimensions, component weight, and planned production quantity when requesting a project review.
