Exterior Deck
As the new generation of inorganic eco-friendly building materials, MGO Exterior Deck boards have become the preferred material for outdoor walkways, scenic platforms, and other outdoor construction projects due to their lightweight strength, fire resistance, moisture protection, and weather resistance. Compared to traditional wooden walkway boards,MGO Exterior Deck boards not only offer a longer service life and lower maintenance costs but also superior overall performance, making them ideal for environments with stringent durability requirements such as coastal areas, wetlands, and parks.

Product Introduction

MGO Exterior Deck boards are primarily made from a ternary system of magnesium oxide, magnesium chloride (or magnesium sulfate), and water, combined with modifiers to form stable magnesium-based cementitious materials. These are then reinforced with alkali-resistant fiberglass mesh and filled with lightweight materials, resulting in a new type of non-combustible decorative material.
When used in outdoor walkways, their performance advantages are significant:
1,Lightweight and High-Strength, Easy to Install
With an apparent density of only 0.85-1.5 t/m³, they are much lighter than traditional concrete materials yet possess excellent compressive and flexural strength. For example, in typical walkway construction scenarios, using 15mm thick deck boards on a 4-meter span walkway results in a weight of about 15.1 kg per square meter. Even under normal pedestrian traffic and light maintenance equipment movement, the board remains flat without noticeable deformation, demonstrating reliable load-bearing capacity. Additionally, during transportation, a single person can easily handle large panels, significantly reducing labor costs and transport difficulties. Installation does not require heavy lifting equipment, effectively improving construction efficiency and saving considerable time and labor costs for walkway construction.
2,Moisture and Water-Resistant, Unaffected by Humid Environments
After soaking in water for more than seven days, they remain unchanged without deformation or swelling, exhibiting a dry-wet deformation rate letss than 0.3%. Even in alternating dry-cold or high-humidity environments, they resist condensation and damp air, making them ideal for coastal and lakeside settings.
3,Excellent Weather Resistance, Suitable for Extreme Climates
After special processing, they exhibit excellent water resistance, heat resistance, and UV resistance, unaffected by rain or temperature fluctuations. Spray-radiation cycle tests show that their flexural strength retention rate exceeds 50% in outdoor sun and rain exposure. Real-world applications in Beijing have proven that modified MOCBs can last over 24 years.
4,Comprehensive Protection, Ensuring Safety
Naturally resistant to insects, mold, and cracking, they do not suffer from rot or insect infestation like wood. Their fire performance meets the GB8624-2006 A1 non-combustible standard-zero flame duration, no combustion at 800°C, and no flames at 1200°C, providing solid fire safety for walkways.
5,Environmentally Friendly and Safe, Embracing Green Concepts
Free from asbestos, formaldehyde, benzene, and harmful radioactive elements, they produce no smoke, toxins, or odors when exposed to fire. Made from natural mineral powders and plant fibers, they undergo natural curing with low energy consumption and zero pollutant emissions, fully meeting modern green building standards.
Diverse Application Scenarios and Construction Advantages
The versatility of MGO boards offers landscape designers and architects extensive creative space, suitable for various outdoor settings:
1,Coastal Walkways and Wetland Trails
Their outstanding moisture and water resistance make them stable in high-humidity environments. Unlike wood that rots and deforms, MOCBs maintain structural integrity even after prolonged exposure to moisture or direct submersion. Successful applications in venues at the Shanghai World Expo and parts of the Shanghai Metro demonstrate their reliability in humid conditions.
2,Forest Parks and Natural Scenic Areas
Fire resistance enhances safety in wilderness environments, reducing fire risks. Their insect and mold resistance prevents chemical preservatives from polluting the natural ecosystem, protecting the pristine environment of scenic areas.
3,Urban Landscape Platforms and Rooftop Gardens
Their lightweight nature reduces structural loads, especially suitable for rooftop gardens and elevated viewing platforms where weight sensitivity is crucial. They meet functional needs while ensuring building safety.
4,Commercial Complex Outdoor Spaces
Shopping centers and hotels can utilize MOCBs for safe and durable paving in outdoor leisure areas and terraces. Their surfaces support paint, wood-grain finishes, and other decorative treatments, easily adapting to various design styles.
Construction Convenience Highlights
- Can be cut arbitrarily without warping or cracking issues.
- Compatible with iron nails, self-tapping screws, and nail guns; flexible connection methods.
- Pollution-free construction with zero impact on the surrounding environment.
- Significantly shortens project timelines, indirectly reducing costs.
Technical Parameters and Specification Selection
Based on project needs, MGO Exterior Deck boards offer flexible specifications and configurations:
Standard Specifications
- Dimensions: 2440×1220mm (custom sizes available)
- Thickness: 12-25mm (recommended thickness for outdoor walkways is 12mm and above)
Key Physical Properties
- Apparent Density: 1.2-1.5 t/m³
- Moisture Content: ≤8%
- Dry Shrinkage Rate: ≤0.3%
- Flexural Strength: >16 MPa
- Impact Strength: >5.5 Kj/m²
- Fire Resistance Limit: >2 hours
Maintenance Costs and Service Life
Compared to traditional wooden walkway boards, MOCBs require almost no special maintenance:
- No need for regular anti-corrosion treatment as they do not rot or deform due to moisture.
- No cracking or warping issues, maintaining surface flatness long-term.
- Surface has strong weather resistance, ensuring color stability.
- Simple cleaning with just water rinsing.
According to accelerated aging tests and real-world application data, properly modified MOCBs in northern cold regions far outlast ordinary wood. Even in harsh climates, they maintain stable performance, significantly reducing the maintenance and replacement costs over the entire lifecycle of the walkway.
Our exterior deck boards combine lightweight strength, fire resistance, moisture protection, durability, and environmental safety, making them an ideal alternative to traditional wooden materials. As the construction industry increasingly demands safety, environmental protection, and durability, their application prospects in outdoor landscape engineering will become even broader. Choosing our Exterior Deck not only ensures project quality but also actively promotes sustainable development and green building concepts.
