Outdoor Composite deck joist span selection guide: key factors to ensure long-term firmness

In outdoor environments, Composite deck, as an emerging environmentally friendly floor material, is increasingly popular among consumers due to its advantages of waterproof, moisture-proof, UV-resistant, and anti-aging. However, one of the key factors to ensure the long-term use of Composite deck is to reasonably select the keel span. This article will elaborate on the selection of outdoor Composite deck joist span to help you better ensure the firmness of the floor.

1. The importance of outdoor Composite deck joist span

The keel span refers to the size of the lateral distance between the keels, which has a vital impact on the strength, stiffness, and service life of the Composite deck. The appropriate keel span can ensure that the floor is not easily deformed or broken during use, and can also improve the stability of the floor. On the contrary, if the keel span is too large or too small, it will have a negative impact on the use of the floor.

2. How to determine the appropriate keel span

1. Understand the strength and rigidity of Composite deck

The strength and rigidity of Composite deck are the main factors that determine the keel span. Strength refers to the ability of floor materials to withstand external forces, and rigidity refers to the ability of the floor to resist deformation when subjected to force. Composite decks of different brands and types have different strengths and rigidities. Therefore, when choosing the keel span, you must first understand the strength and rigidity of the Composite deck used.

2. Control the keel span below 35 cm

For users who do not know the strength and rigidity of the floor, it is recommended to control the keel span below 35 cm. This is because a span of less than 35 cm can ensure the firmness of the floor during long-term use. Of course, if you understand the strength and rigidity of the floor, you can adjust the keel span appropriately according to the actual situation.

3. Detailed and vivid case analysis

The following is a case study on the consequences of improper selection of outdoor Composite deck joist span:

A community outdoor square used Composite deck as the ground material. Due to the insufficient understanding of the strength and rigidity of Composite deck by the construction party, the keel span was set to 50 cm. During use, the floor showed obvious deformation and fracture, which seriously affected the beauty and use effect of the square. After inspection, it was found that the excessive keel span was the main cause of floor damage.

In order to solve this problem, the construction party re-paved and adjusted the keel span to less than 35 cm. After a period of use, the firmness of the floor was clearly visible, and no deformation or fracture occurred.

4. Summary

The selection of outdoor Composite deck joist span is a key factor in ensuring the long-term use of the floor. When selecting the keel span, it is necessary to fully understand the strength and rigidity of the Composite deck and make reasonable adjustments according to the actual situation. For users who do not know the strength and rigidity of the floor, it is recommended to control the keel span to less than 35 cm to ensure long-term firmness.

Through the above content, I believe everyone has a deeper understanding of the selection of outdoor Composite deck joist span. In practical applications, we must make adjustments according to specific circumstances to ensure that the Composite deck is safe, stable and beautiful during use.
