The BULU magnesium sulfate bare raised floor is a new fire-retardant raised floor made primarily of magnesium sulfate, reinforced with polymer-modified materials and lightweight fillers like wood fiber. It integrates environmental protection, fire resistance, energy saving, and moisture resistance, making it an innovative flame-retardant solution. Designed for commercial, office, and public spaces, BULU raised floors offer durability and safety while meeting modern building standards.

System performance standards are the primary consideration as they reflect the overall performance of a typical installation. While panel-specific standards, such as concentrated load ratings, are commonly used to specify floor systems, they do not accurately represent real-world performance. This is because testing is conducted on individual panel test blocks rather than the complete installed system, including its foundation structure.
| Type | Specification | Concentrated Load | Safety Factor | Impact Load | Ultimate Load | Uniform Load | Standard | Fire Protection |
| International | mm | N | (min.2.0) | N | N | (N/M⊃2;） | ||
| FS440 | 500*500/600*600 | ≥1960 | Pass | 295 | ≥5880 | 9720 | ClSCA | A1 |
| FS662 | 500*500/600*600 | ≥2950 | Pass | 445 | ≥8850 | 12500 | ClSCA | A1 |
Except for the design load, the tests were conducted using the CISCA recommended test procedure for access floors.
1. The design load is tested using the CISCA concentrated load test method on the actual substructure rather than the steel block. The design load is determined by the smaller of the ultimate load divided by two or the point where permanent damage begins to occur (yield point).
2. The safety factor is the multiple of the design load and the ultimate load. International standards recommend a minimum of 2.
What is MgSO4 Raised Floor?
Magnesium oxide raised flooring is a durable and versatile flooring system made from high-density magnesium oxide encapsulated in a protective steel shell, often galvanized. This system is designed to provide exceptional strength, fire resistance, and durability, making it suitable for various commercial, industrial, and data center applications. The magnesium oxide material is naturally fire-resistant, offering enhanced protection in areas that require stringent fire safety standards. Additionally, the steel encapsulation protects the magnesium oxide from corrosion, ensuring longevity even in humid or chemically challenging environments. The flooring system is also known for its excellent sound insulation properties, making it ideal for spaces that require noise reduction, such as office buildings and server rooms. The modular design allows for easy installation, maintenance, and upgrades, with panels that can be quickly removed or replaced. This flexibility makes it especially useful in environments where infrastructure changes are frequent. Furthermore, magnesium oxide is an environmentally friendly material, contributing to sustainable building practices. With its combination of strength, safety, and sustainability, magnesium oxide raised flooring is becoming an increasingly popular choice for modern commercial and industrial spaces.
The production of MgSO₄ Raised Access Floor involves mixing magnesium sulfate (MgSO₄), magnesium oxide (MgO), reinforcing fibers, and additives to form a durable, fire-resistant core. The core is molded, compressed, dried, and hardened before being encapsulated with galvanized steel or aluminum foil for enhanced strength and moisture resistance. Panels undergo strict quality testing for load capacity, fire resistance, and moisture protection before being packaged and shipped. This flooring offers high strength, fireproofing, and eco-friendly benefits.
BULU encapsulated magnesium oxide raised floor panels weigh 12-13kg, significantly lighter than most other panels, which typically weigh 15kg or more. This lighter weight makes the panels easier for workers to transport and install, improving efficiency on-site. Additionally, because the panels are lighter, more units can be packed into a single shipping container, maximizing space and reducing sea freight costs. This combination of easier installation and cost savings on shipping makes our raised floor solution both practical and cost-effective for our clients.
Rust-proof
BULU magnesium sulfate raised flooring has a UV coating on the surface for greater durability. Unlike traditional raised floors, it does not use cold-rolled steel, eliminating the risk of rust and surface blistering after installation. This ensures long-term stability, reliability and a maintenance-free solution for commercial and office environments.
Improved Acoustic Performance
BULU magnesium sulfate raised floor enhances a building’s acoustic performance by significantly reducing noise transmission between floors. Unlike traditional raised floors, it has no cold-rolled steel on the surface, resulting in a quieter walking noise of approximately 30 decibels, compared to 70-80 decibels for other raised floors. This improved sound insulation is particularly beneficial for commercial buildings, where privacy, confidentiality, and a quiet working environment are essential.
Enhanced Flexibility and Adaptability
Raised floor systems are designed to be highly flexible and adaptable, making it easier to reconfigure the layout of a space or install new equipment and services. This is especially important for commercial office buildings, where businesses may need to quickly adapt to changing market conditions or new technologies.
