Guide to the Spa Framework System: Answers to Components, Installation and Maintenance
A spa contains multiple functional systems, and the structure within and between individual systems is designed with great precision. Despite this intricate design, the spa is capable of supporting multiple people simultaneously, allowing them to fully relax their body weight and enjoy hydrotherapy. All of this is thanks to a system that doesn’t directly impact the spa experience but is often overlooked—the spa framework system. The spa framework system plays an irreplaceable role in maintaining the overall spa safety, functionality and aesthetics, and today we'll be answering some frequently asked questions to get a deeper understanding of the system that's even more important than we thought.

What is the Spa Framework System?

The spa framework system is a fundamental support structure of a spa, which includes:
Frame: It bears the weight of the entire spa systems, providing stable support and ensuring secure installation.
Skirt Board
·It covers the bottom and sides of the spa, offering additional support.
·It helps prevent dust accumulation and protects against damage to components, as well as preventing pests like insects and snakes from entering.
·It serves a decorative purpose by concealing pipes and the frame.
·It can be easily disassembled and installed, ensuring timely access for maintenance and repairs of the spa's internal components.

What materials are commonly used in spa framing systems?

The frame can be made of steel (e.g. stainless steel or galvanized steel), aluminum, PVC or ABS plastic, etc., of which steel is the last and most popular. Steel stands out for its exceptional strength compared to other materials. Additionally, stainless steel, in particular, offers excellent corrosion resistance. Steel is also modern and aesthetically pleasing. These characteristics make it the ideal material for supporting a spa.
Skirt boards can be made of PS, plastic, and other composite materials, the most popular of which is PS (Polystyrene). This is due to several superior characteristics of PS material:

·Lightweight: With low density and light weight, it is easy to transport and install.
·Waterproof: It is moisture-resistant, does not absorb water, and is not prone to swelling or deformation, ensuring long-lasting durability.
·Easy to process: It has a good texture and can undergo various surface treatments such as smooth finishes, printing, embossing, double-sided embossing, and spraying. It can be nailed, sawed, or planed, making it easy to cut and assemble.
·Weather-resistant: PS has strong UV resistance and can withstand high temperatures of up to 80°C. It is not easily faded or aged, ensuring a longer service life.
·Durable: The surface hardness is high, able to resist light friction and daily wear and tear, also can prevent damage from pests like insects and snakes, maintaining both safety and aesthetics.

How to Install and Maintain PS Skirt Board?

Installation Guidance:
The whole process is relatively simple, you need to prepare a screwdriver, screws, tape measure, PS-specific adhesive and PS skirt board accessories.
1. Clean the frame of the spa.
2. Use screws and adhesive to secure the PS skirt board to the frame.
3. Gently press until all joints are tightly and seamlessly connected.
4. Wait until fully dry before using the spa.

These steps can be used as a reference for the subsequent removal and installation of skirt boards for access to repair internal components. If necessary, you can contact professional technicians for assistance or to handle the entire installation process. 
Additionally, tool-free installation snap-on PS skirt boards are now available on the market, which not only prevent installation errors but also save time and effort.
Maintenance Tips:

Regular Cleaning: Use a mild cleaner and a soft towel to wipe the surface, preventing stains and limescale. Be careful not to use hard brushes and strong acid and alkali cleaners to prevent accelerated fading and aging of the PS skirt board.
Check Connections: To prevent the spa structure from loosening and to prevent moisture from entering the spa, remember to use adhesive or sealing strips to secure the connection of skirt boards.
What's more, while PS material has good durability, it does not mean it is completely resistant to all improper use. Durability does not mean that it does not require maintenance:
Avoid Scratches: Prevent striking from sharp objects and frequent scraping. Use fine sandpaper to gently smooth out scratched areas. For severe scratches or damage, it is recommended to use professional repair tools or replace the skirt board to avoid affecting performance.
Prevent Long-term Exposure: Avoid long-term exposure to direct sunlight and high temperature operation. It is recommended to use something that can cover the spa or sunshade to extend the lifespan of the skirt board.
