Even if the product is in good condition at the time of shipment, red rust may appear after two weeks. We will explain the management of the substrate at the edges, holes, and welds.
Claims of rust reoccurrence may be discovered not immediately after delivery, but during storage or before assembly checks. The areas that require particular attention are the ends, around holes, and weld joints. Even if the surface is covered with paint, if red rust, scale, or moisture remains in the substrate, corrosion will progress beneath the paint film. Even a single thin film area can become an entry point for moisture, leading to red rust, blistering, and peeling. Initially, it is important to check the location of rust occurrence, the number of days in storage, the packaging condition, and the variation in film thickness. For permanent measures, it is crucial to connect the five processes of rust removal, degreasing, drying, film thickness confirmation, and pre-packaging checks as one rust prevention management system, rather than viewing them separately. By not attributing the cause solely to the customer's storage conditions and documenting the substrate condition before painting and key area checks before shipment, it becomes easier to reduce recurrence claims. Please utilize confirmation materials for reviewing rust prevention management. Keeping photos of red rust, storage duration, and packaging conditions will make it easier to determine whether to focus on the painting process or the storage environment.

Company information
We are not just a "subcontracted painting factory." Established in 1958, our company has a foundation of painting technology and also specializes in chemical treatment, stripping, and cleaning, functioning as the "external surface treatment department" in your organizational chart. Based on our philosophy of "preparation is eight-tenths of the work," we emphasize participation from the "upstream process" before the drawings are finalized. We conduct test painting on a wide range of metals and difficult materials, and we produce the entire process from assembly, packaging, to delivery, thereby reducing your management workload. Additionally, by being able to perform zinc phosphate treatment in-house, we achieve stable painting quality. Furthermore, our micro-heating stripping technology, which does not use chemicals, maintains the electrical state of the "jigs (hangers)" that influence painting quality. Our approach of "pre-treatment determines painting quality" ensures the stability of the paint film during mass production. Rather than simply "applying specified standards," we work backwards to achieve optimal painting specifications and prevent scratches during transportation, sparing no effort in thorough discussions from the outset. This diligent preparation is the shortest path to preventing rework and minimizing total costs. From the development stage, please utilize the expertise of our specialists as part of your production line.
