GuarDeck® – Deploy-Ready Bridge Decking

MAADI Group Introduction

GuarDeck® offers advanced design technologies that are a cut above traditional concrete and steel construction. Lightweight structural aluminum reduces dead load and increases bridge life. This product is also easily produced in the factory.

GuarDeck® deploys in record time and cuts down on maintenance costs in the long run due to minimal upkeep. This innovative design system is resilient, and tailored to a range of applications and environments.

Design InnovationMAADI Group works with municipalities, developers, architects, construction companies, governments and other parties to offer innovative Accelerated Bridge Construction (ABC) that cuts down on traffic interruptions and costly traffic control. This game-changing aluminum bridge decking solution offers incredible advantages over traditional concrete and steel construction, such as lightweight structural aluminum to reduce dead load, and no painting or corrosion.

Whether replacing existing decking on an older bridge or building a new one, GuarDeck® saves time on installation as the mechanical connections are fast and easy to install. A team can install a weld-free aluminum deck and open the bridge to traffic later that same day. The aluminum product’s lightweight system is especially good for structures tailored to pedestrians and 15-ton vehicles, road or movable bridges, civil security, temporary or military bridges, maritime structures and construction platforms.

Quality AssuranceGuarDeck® manufacturing is ISO 9001:2015 accredited and certified. Our product is produced to the highest and most rigorous quality standards in our industry.

SpecificationsMAADI Group engineers adhere to design specifications that meet all local, regional and national building and bridge codes and standards.

MAADI Group specializes in aluminum bridge decking that is unmatched for durability and lasts several decades. Our professional engineers designed GuarDeck®, a weld-free extruded deck system with built-in ribs to provide an anti-slip surface. GuarDeck® allows fast installation with minimal upkeep.

Longer bridge lifeGuarDeck® represents a cut above in factory aluminum bridge decking. Consistent manufacturing and quality control mean that MAADI Group can deliver faster installation that’s also better quality than field-built decks.

This engineer-designed product is ideal for new or existing bridge retrofit with quick installation and minimal disruption to people and traffic. Whether permanent or temporary, this product fits well into most environments and situations where durability and rapid installation are top priority.

The following is just a sampling of the kinds of projects that can benefit from GuarDeck®:- Pedestrian and 15-ton vehicle bridges

- Maritime Structures

- Civil Security Bridges

- Temporary Bridges

- Military Bridges

- Industrial Bridges

- Extend roadway bridge for cantilevered bike path

Facts on aluminum deckingA North American study 1 shows that older projects using aluminum decking instead of concrete, steel and wood have stood the test of time. Between 1946 and 1963, nine bridges were built with aluminum beams and girders and six still exist. Gradually more countries, such as Japan, Norway and Sweden are recognizing the benefits of aluminum versus steel construction and are using aluminum extrusions in the repair and construction of bridge decks.

MAADI Group Advantages

Stands up to coldThis product is ideal for bridges and other highway structures in colder climates. It eliminates concerns about brittle fracture, even in the most severe Arctic weather. The strength of aluminum includes tensile, yield and impact strength which allow for use in climates with extremely low temperatures.

Aluminum: The eco-conscious metal MAADI Group is sensitive to climate change. To that end we have designed GuarDeck® to reduce your project’s carbon footprint (CO2 emissions) by using 20 percent recycled aluminum and renewable energy. And we use the most innovative, energy efficient technology to produce the remaining 80 percent of your bridge deck.

Aluminum bridge decks last generations and the components are 100 percent recyclable, and potentially reusable. About 75 percent of aluminum that is produced is still in use today thanks to recycling programs.

Versatile designsDue to its lightweight and versatile nature aluminum can be shaped into a myriad of designs. Attractive and heavy-duty at the same time, this material creates bridge decking that integrates well into all built and natural environments. Our deck surface also has built-in ribs to prevent slip.

Increased useA wide variety of cross-sectional shapes of aluminum extrusion has led to the increased use of aluminum for bridge decks. This has signaled the potential in North America and worldwide for its use in other applications.

Aluminum’s time has come Over the past few years, aluminum has seen improved properties and advances in knowledge concerning aluminum’s mechanical behavior, along with much improved alloys and tempers. The structural engineering community is already using this knowledge, which is gradually translating into more governments and municipalities recognizing the advantages of aluminum.

A foundation for good roadsGuarDeck® facilitates seamless connections between secondary roads, bike paths, trails, pathways and other structures. It solves complex issues of deficient, narrow or outdated bridges, providing ready made solutions that endure.

Lighter than steelAluminum bridge decks are 70 to 80 percent lighter than concrete and most metal, (about 10 psf – 0.5 kPa), which makes it easier to handle and install. This lightweight, versatile material reduces dead load and offers increased bridge width and capacity without the need to strengthen supporting bridge elements. This is especially important for load-restricted bridges, historic bridges, movable bridges and bridges with narrow roadways requiring expansions for bicycle paths or walkways.

Hardwearing and resilient Using marine grade aluminum, our bridge decks require no painting and minimal upkeep. Lasting up to 100 years, and naturally resistant to corrosion, this bridge deck type is better suited—than steel or concrete—to de-icing during colder months.

Accelerated Bridge Construction (ABC) This unique type of construction allows for a quick-turnaround installation when compared to concrete which typically requires extensive formwork and cure time.

Reducing costs mattersUsing GuarDeck® could mean decreasing costs for movable bridges and bridges with long spans where dead weight is the main load.

In-factory for faster turnaroundGuarDeck® is prefabricated in a factory and shipped ready to install with standard manual tools. This system uses custom aluminum hollow extrusions that attach easily to the main I-beams with special stainless steel fasteners and clamps. Prefabricated aluminum deck extrusions can be installed faster than other systems and require no on-site drilling or welding.
