There are several qualities to consider in determining whether modular decking is the best choice for your project. These include the essentially isotropic deck, staggered connection structure, wear surface, and seal coating. Learn more about these qualities and the benefits of modular decking in this article.
Staggered Connection Structure
The modular decking components include systems that can incorporate a staggering connection structure, providing extra structural support without requiring additional structures. The illustration below shows a deck panel with a staggering connection structure. In this example, the horizontal flanges of a deck panel are connected by an elongated channel wall. The staggered connection structure allows the plumbing to be located between the components.
In some embodiments, the modular decking component has a substantially continuous bottom and top flange, forming a bi-directional system with structural performance corresponding to an isotropic plate. In addition, the deck board surface can include various textures, patterns, and treatments. These ridges may be positioned to mate with tab 75 on the foundational component.
Essentially Isotropic Deck
Essentially isotropic decking is a composite decking system made of multiple elongate elements with parallel flanges and beveled outer edges. The elongated elements are interconnected by webs that may be inclined or vertical. The resulting structure is an essentially triangular cross-section.
An essentially isotropic decking system is ideal for bridge decks, providing structural strength in shear and bending. Its layered design provides bending and shear strength in both transverse and longitudinal directions.
Wear Surface
Modular decking components are designed to have a consistent wear surface. The components are formed of aluminum extrusions and can be assembled easily. They are light and corrosion-resistant. The elongated aluminum elements are assembled using well-known fastening elements to provide a substantially continuous upper surface. The aluminum extrusions are also coated with a protective wearing layer for long-term use.
Modular decking components are also used in bridges. They are designed as a joint flange that connects the girders and deck. In this way, the rafters and decking remain firmly attached and are more resistant to wear and tear. The use of modular decking components also reduces the construction time and can reduce the effect on traffic.
Sealing Coat
Whether you’re installing a modular deck or a traditional wood deck, several factors must be considered before applying a coating. You can consider applying a sealant if you want to protect your modular deck against water damage. This protective coating will prevent moisture damage and help prevent stains and mildew. It can also help protect your deck from UV damage and color fading. Some products are ready-to-use, meaning you can apply them immediately without pre-treatment. Some are EPA-registered and only require one application. These products also protect the wood against termites and ants.
To determine the durability of a deck sealant, look for a certification that tests the material’s durability under immersion conditions. Manufacturers or distributors typically perform this test. The sealant must pass several tests, including adhesion and cohesive failure.
Clear Finish
A clear urethane finish is a durable coating that adds an appealing sheen and can conceal superficial scratches in wood. It’s a single-part product that can be applied with a brush and is highly resistant to cleaning solutions and harsh chemicals. It’s also less expensive and easier to apply than conventional one-part varnishes.
The best choice for wood-based decks is clear urethane, which can protect against UV rays and weather. While it’s more commonly used in interior wood flooring, this versatile finish can also be used as a topcoat for decks. It’s rugged, waterproof, and protects the wood from damage from the sun. When choosing a polyurethane finish for your deck, look for a low-VOC product. This will help improve air quality.
