1. Powder Coating Processes
As a manufacture of high quality outdoor site furniture, Sunperk Site Furnishings offers a highly durable and superior finish for all of our metal collections in order to provide our valued customers a great outdoor experience. And most importantly, our quality powder coating is renowned for being environmentally responsible which contains no VOCs and solvents.
Sunperk’s Powder Coating is a dry finishing process, which uses finely ground particles of pigment and resin that are electrostatically charged and evenly sprayed onto electrically grounded parts. The charged powder particles adhere to the parts and are held there until melted and fused into a smooth coating in a curing oven. Before coating, the parts to be coated are first prepared similarly to conventional liquid coated parts. Sunperk Site Furnishings has a fully equipped processing line for these steps. Following is the procedure of powder coating from start to finish.
Sunperk Site Furnishings has been converting to environmentally friendly methods and materials in conjunction with the general industrial trend. Our well-selected pretreatment processes can achieve these objectives. Not all of these methods work on all surfaces. The pretreatment will vary depending on the required final use of the substrate. A complete pretreatment process will consist of: Cleaning, Rinsing, Conversion Coating, Seal Rinsing, and Drying and Cooling.
Sunperk Sit Furnishings uses Electrostatic Powder Spraying as the method for processing this step. The extreme cost of the equipment exchanged our advantages compared with others:
- Difficult shapes can be coated
- Film thickness can vary
- Simple and low cost for automation
- Color can be changed relatively simply
- No pre-heating of components required
The electrostatic spray process makes use of electrically charging the powder particles. The powder is delivered by a powder pump and a transport airflow system to the electrostatic spray gun. As the charged particles come close to the grounded work piece, electrostatic attraction causes the particles to deposit and adhere to the work piece.
Quality & Testing
To polymerize the powder applied to the substrate we must heat both to a high temperature for a few minutes. This is the curing process. It is important to note that for any particular powder coating application, Sunperk Site Furnishings has technical specifications and quality standards to be met, which refer to specific tests and testing equipments. During the powder application process faults can occur, as with any other process. If the part cannot be utilized in a less critical or sensitive situation, it may either be repaired or scrapped. The possible rework actions include Sanding, Touch-up, Recoating, Double-curing, and Stripping.
2. Color Options
We have a wide variety of colors of powder coating to choose from, e.g. blue, red, black, green, yellow, silver, etc. Special colors, such as pink, light green and orange, are also available, but with minimal extra fees and longer lead time.
An international RAL color code is mandatory for customization, and any color is theoretically available. Customers could also select glossy or matt options, free of charge. Metallic colors that contain shinny metal particles are feasible, but require samples for color matching. Bolts could be powder coated as well to accomplish a uniform aesthetic appeal. A list of RAL colors can be found here http://www.ralcolor.com/.
Below are some popular colors that we stock on a regular basis.
It is recommended to choose RAL colors from a commercial RAL color chart as shown by the picture below, since accuracy of colors showing on a monitor varies from 90%-99%, but you could use online colors for a rough understanding of RAL colors.
Models processed with Hot-Dipped Galvanization or manufactured of stainless steel don’t have options of extra colored coating finishes.
3. Recycled Plastic Wood Options
Plastic wood is capable of mimicking colors and textures of wood, but in the meanwhile thanks to stable chemical property of plastic, no corrosion and cracks would occur. A bench made of this synthetic material is an enjoyable place to sit on, as a result of its adequate softness. Following pictures listed the options of HDPE (High-density Polyethylene) plastic wood.
Plastic-wood composite, PS (Polystyrene) plastic wood and real wood are also customizable. Please contact us for availability of the materials prior to placing order. Certain materials may experience shortage during certain periods of the year. We could send limited amount of plastic wood samples for final approval of the purchase.

7.Memorial Bench Tips
We have many customers inquiring about memorial benches. It is important to treat the benches carefully as much as we care about the ones who brought us beautiful memories. Here are some info.
- We only supply benches, and customers need to out-source laser printed stainless steel plaques. There are plenty of workshops, so don’t worry.
- Choose recycled plastic benches over metal benches. Installation of memorial plaque needs drilling holes on the bench. In the case of metal benches, drilling holes exposes raw metal to the air, and over a period of time, corrosion initiates and migrates to other part of the bench, and resulting in large area of rusting. However this scenario would not happen on recycled plastic benches.
- Soft property of plastic wood benches is easier for installation of memorial plaque.
- Possibility of loosening of screws that attach plaque to the bench may causing unpleased noise when plaque is contacting the metal bench.
- If an unsuccessful drilling is performed, it may require replacement of whole metal bench, but in case of recycled plastic bench, simply replacement of a lumber.
8. Lead Time
An usual lead time is about 8 weeks for customized product. We are relatively busy during spring and summer. Lead time also depends on customers’ position on the wait list as well as the weather, specifically windy and snowy winter conditions. Lead time may be also affected by requirements of matching colors and ordering rare colors, or any other special requirements.
