How are fiberglass pools made?

When it comes to choosing a swimming pool for your backyard oasis, fiberglass pools have gained enormous popularity in recent years. Known for their durability, low maintenance, and aesthetic appeal, fiberglass pools offer a perfect balance of functionality and beauty. But have you ever wondered how these inground fiberglass pools are made? 
​
Step 1: Design and Mold Creation:

The first step in manufacturing a fiberglass pool involves designing the pool and creating a mold. The pool design is carefully planned, taking into consideration factors such as shape, size, depth, and any additional features like built-in steps or benches. Once the design is finalized, a mold is created based on those specifications.
Typically, the mold is made from a combination of fiberglass and other composite materials. The mold is created using a reverse engineering technique, where a master mold is made based on the desired pool design. The master mold is then used to create the production molds, which will be used to manufacture multiple pools.

Step 2: Gel Coat Application:

The next step is the application of a gel coat to the mold. The gel coat is a specialized resin-based material that provides the pool's smooth and glossy surface. It is typically pigmented to give the pool its desired color. The gel coat is sprayed onto the mold, ensuring an even and consistent layer.

Step 3: Fiberglass Reinforcement:

Once the gel coat has been applied, fiberglass reinforcement is added to provide structural integrity to the pool. The structural fabrication of a Sun Pool fiberglass pool begins with the hand laid process of modified epoxy known as vinyl ester resin applied to the gel coat. This material will increase the impact strength of the pool surface as well as provide protection against long-term water exposure.
 

Step 4: Curing and Lamination:
​
After the fiberglass reinforcement has been applied, the pool undergoes a curing process. Curing is typically done at a controlled temperature to allow the resin to harden and bond with the fiberglass. This process is crucial in ensuring the pool's strength and durability.

Once the curing process is complete, additional layers of fiberglass and resin may be added to enhance the pool's structural integrity. This lamination process reinforces critical areas such as the pool's walls, floor, and coping, making them more resilient to external forces and pressure.

Step 5: Trimming, Finishing, and Quality Control:


After the pool has fully cured, it is carefully removed from the mold. Trimming and finishing processes are then carried out to remove any excess fiberglass and achieve the desired shape and dimensions. Skilled craftsmen meticulously sand and polish the pool's surface, ensuring a smooth and flawless finish.

Before the pool is ready to be shipped, it undergoes a rigorous quality control inspection. Each pool is thoroughly examined for any defects, imperfections, or structural issues. This ensures that only the highest quality fiberglass pools reach the customers.

​Conclusion:


The manufacturing process of inground fiberglass pools combines a blend of artistry, engineering, and craftsmanship. From design and mold creation to the final finishing touches, each step is carefully executed to produce a durable, stylish, and long-lasting swimming pool.
