A metal-fabrication plant has commissioned a complete overhead conveyor coating and curing line from CoatTech Intelligent Equipment (Guangzhou) CO., LTD.

The project transforms a previously batch-oriented finishing operation into a continuous suspended flow for welded racks, mesh components and tubular frames.

01 Background and challenge

The customer coats high quantities of welded metal frames, mesh/rack components and bar-type parts. Batch-style handling created congestion on the shop floor, uneven hanging density and variable cure/dry performance. The brief was a continuous-flow layout that kept parts suspended, reduced floor occupation and standardized process exposure.

Limited floor space — a high-bay hall with little room for additional batch stations

Mixed part shapes — long bars, welded meshes and rack frames to be processed on one line

Stable hanging pitch — need for smooth curves, transfers and accumulation without product collision

Enclosed process and curing — requirement for a clean coating environment and controlled drying/curing

Less manual movement — goal to cut rework and free operators from repetitive lifting and carrying

02 CoatTech solution

CoatTech supplied a modular overhead conveyor coating line with multi-level steel supports, curved and accumulating track sections, dedicated hanging jigs, enclosed side-wall process chambers and a light-colored insulated tunnel for curing/drying. The layout uses vertical space and directs parts through loading, coating preparation/process zones and curing in a single coordinated flow.

Overhead monorail with curves and accumulation — continuous product movement with built-in buffering between stations

Custom hanging jigs — purpose-made fixtures for bars, mesh and rack parts, exposing all coated surfaces

Enclosed process tunnel — side-wall chambers with access doors for coating and preparation

Insulated curing/drying tunnel — controlled environment with utility and service access for repeatable results

Modular steel structure — column-supported frame integrating rail, chambers and maintenance walkways

Full project scope — layout engineering, fabrication, delivery, installation support and commissioning by CoatTech

03 Results

More organized continuous flow — parts move through the line without blocking assembly or logistics routes

Reduced floor-level congestion — overhead transport frees ground area for forklifts and handling

Improved coating consistency — stable hanging pitch and controlled process exposure reduce variation

Adaptable tooling — one line handles multiple SKUs through interchangeable fixtures

Scalable structure — the modular frame allows future line extensions as output grows

04 Project data

Frequently Asked Questions

Q: What does a coating line case study show? A: It documents a real client challenge, the CoatTech solution and the measurable results after installation.

Q: Which parts were processed in this project? A: Welded racks, mesh bases, tubular frames, brackets and other fabricated metal components.

Q: Can the line handle long and bulky products? A: Yes — the elevated rail and process tunnel accommodate long parts, while curves and accumulation save floor space.

Q: Is the conveyor speed adjustable? A: The trolley chain runs at an adjustable pace so dwell time in each process stage matches the coating and output required.

Q: Does CoatTech support installation? A: Yes — CoatTech handles layout engineering, fabrication, delivery, installation support and commissioning.
