S D Company Ltd., a professional manufacturer of outdoor garden products including metal garden fences and garden decor, has recently completed a factory upgrade. The project, focused on optimizing core production processes and improving product quality, centers on refining the spray coating technology for metal garden fences—strengthening the company’s ability to deliver durable, aesthetically pleasing outdoor products.
Focus on Core Craftsmanship: Elevating Spray Coating
The upgraded factory has optimized key production links, with the spray coating process being the primary improvement. Unlike the previous workflow, the revised spray coating process adds more detailed pretreatment steps and stricter quality inspection links, directly addressing issues like uneven coating and poor weather resistance that affect product lifespan.
Detailed Spray Coating Workflow
The refined spray coating process starts with thorough pretreatment of metal fence components: each part is first degreased to remove oil stains, then derusted to eliminate surface rust spots, and finally treated with a phosphating solution to form a protective layer that enhances coating adhesion. After pretreatment, components are moved to a dedicated spray booth to avoid dust interference.
Technicians use professional high-pressure spray guns to apply high-quality polyester powder coating—chosen for its weather resistance and color stability. After the first coating, components are checked for coverage; a second coating is applied where needed to ensure uniformity. Finally, coated components are sent to a curing oven for heat treatment, ensuring the coating adheres firmly and forms a scratch-resistant surface.
Every coated fence panel undergoes manual inspection: workers check for uneven areas by touch, examine color consistency under natural light, and test coating adhesion by gently scratching the surface. “We won’t let any panel with coating flaws leave the factory,” the production supervisor noted. “Customers who use our fences in rainy or sunny areas have already noticed the difference—less fading and no rust spots after long-term use.”
Practical Eco-Friendly Adjustments
In line with market demands for more sustainable products, the factory has switched to low-VOC (volatile organic compound) powder coatings for the spray process, reducing harmful emissions. Additionally, the team has optimized the collection of unused coating powder, reusing recoverable powder to cut material waste—practical steps that align with the company’s focus on responsible production.
“A lot of our customers care about whether products are environmentally friendly, especially those exporting to overseas markets,” said a company sales representative. “Using low-VOC coatings and reusing powder isn’t just about meeting standards—it’s about being responsible to both customers and the environment.”
Improved Production Efficiency
While quality was the main goal, the upgrade also streamlined the spray coating workflow. By setting up a dedicated line for coating and pretreatment, the factory has reduced waiting time between processes, allowing for more efficient handling of orders.
“We used to take longer to fulfill bulk orders for metal garden fences because the coating process was a bottleneck,” the production supervisor explained. “Now, with the optimized workflow, we can process orders faster without compromising quality—this helps us keep up with customer delivery timelines.”
Future Plans: Continuing to Refine Quality
Looking ahead, the company plans to expand the color range of spray coatings based on customer feedback, adding more options that suit different garden styles. “Our priority is always to make products that customers can trust,” said a company manager. “This upgrade is just the start—we’ll keep adjusting processes based on real usage feedback to make our metal garden fences even better.”
