Fireproof Exterior Wall MGO Board Interior Wall Panels Lightweight Magnesium Oxide Board

With comprehensive advantages such as Class A1 non-combustibility, lightweight yet high-strength, moisture-proof and waterproof, and environmental friendliness, magnesium oxide (MgO) boards are versatile building materials that replace traditional gypsum boards and cement boards. Their application scenarios cover multiple fields including construction, industry, decoration, and special sectors. Below is a detailed classification of core application scenarios, with corresponding explanations of product characteristics and practical needs:

 

Main Building Engineering (Core Application Field)

1. Internal and External Partition Wall Systems

Applicable Scenarios: Non-load-bearing partitions in residential buildings, office buildings, shopping malls, hotels, hospitals, schools, and other structures-especially high-rise buildings, seismic zones, and humid environments (toilets, kitchens, basements, underground garages).

Core Advantages:

Lightweight (density only 0.85-1.27g/cm³), reducing building load and increasing usable area (50% thinner than brick walls);

Moisture-proof and waterproof, maintaining shape even after long-term immersion without additional waterproofing;

Combined with light steel keels, fire resistance rating reaches 3-4 hours, meeting fire compartment requirements;

Easy construction: can be directly cut, nailed, and assembled with high flatness for subsequent decoration.

Dense structure forming a carbonized layer at high temperatures, effectively blocking fire spread.

Recommended Types: 12-18mm heavy MgO boards (firewall main body), MgO rock wool sandwich panels (dual requirements of fire protection and thermal insulation).

 

Special Fire Protection Engineering

1. Fire Door Core Panels

Applicable Scenarios: Core filling material for wooden and steel fire doors (replacing traditional vermiculite and perlite cores).

Core Advantages:

Excellent fire resistance, maintaining shape and not falling off at high temperatures to ensure fire door integrity;

Lightweight yet high-strength, reducing fire door weight for easy installation and operation;

Moisture and insect-proof, avoiding mold and insect infestation of the core to extend fire door service life.

 

2. Pipe and Steel Structure Cladding

Applicable Scenarios: Fire protection cladding for building exhaust ducts, ventilation pipes, and cable trays; fire protection of beams and columns in steel structure workshops and warehouses.

Core Advantages:

High temperature resistance and good thermal insulation, delaying temperature rise of pipes/steel structures to meet fire codes;

Flexible construction, allowing cutting and splicing according to pipe shapes for tight fitting;

Inorganic material, non-corrosive to steel structures with long-term stability.

 

3. Fire Partitions and Smoke Barriers

Applicable Scenarios: Smoke barriers (dividing smoke control zones) in large-space buildings such as shopping malls, hotels, and subways; fire partitions in laboratories and dangerous goods warehouses.

Core Advantages:

Non-combustible and smoke-free, effectively blocking smoke diffusion;

Lightweight and easy to install, compatible with electric control systems for automatic lifting;

High strength and impact resistance, not easily damaged.

 

Decoration and Furniture Field

1. Decorative Panels and Substrates

Applicable Scenarios: Wall decoration, accent walls, cabinet doors, wardrobe side panels, bathroom vanities, laboratory workbenches, etc.

Core Advantages:

Smooth surface, directly paintable, veneer-applicable, tile-adherable, or PVC film-laminatable with strong decorativeness;

Moisture and waterproof, not easily deformed or cracked, suitable for furniture in humid environments such as kitchens and bathrooms;

Environmentally friendly and non-toxic, with formaldehyde emission ≤0.12mg/m³, meeting E0-class standards.

 

2. Flooring Substrates

Applicable Scenarios: Fireproof flooring substrates for commercial spaces (shopping malls, office buildings, hospitals) and floor base layers in humid environments (basements, ground floors).

Core Advantages:

Fire-retardant, reducing floor fire risks;

Moisture and insect-proof, avoiding mold and insect infestation of the substrate;

High strength, compression and impact resistance, with strong load-bearing capacity.

Recommended Types: 12-15mm solid MgO boards (requiring wear-resistant surface layers such as PVC or tiles).

 

Industrial and Special Scenarios

1. Cleanroom Engineering

Applicable Scenarios: Walls and ceilings in high-purity environments such as hospital operating rooms, ICUs, food processing plants, electronic cleanrooms, and pharmaceutical factories.

Core Advantages:

Smooth and seamless surface, not easily accumulating dust or breeding bacteria, meeting GMP cleanroom standards;

Moisture and waterproof, easy to clean and disinfect (resistant to alcohol and disinfectant wiping);

Fireproof and environmentally friendly, with no pollutant emission.

Recommended Types: Hollow MgO boards (dual requirements of thermal insulation and cleanliness), color steel composite MgO boards (industrialized installation with high efficiency).

 

2. Cold Storage and Cold Chain Facilities

Applicable Scenarios: Enclosure structures (walls, ceilings, partitions) of cold storage and interior decoration of cold chain transport vehicles.

Core Advantages:

Moisture-proof and thermal insulation, low thermal conductivity, reducing cold energy loss;

Low temperature resistance (no brittleness at -40℃), maintaining stable performance in long-term low-temperature environments;

Lightweight yet high-strength, reducing the weight of cold storage/vehicles to lower energy consumption.

 

3. Marine and Rail Transit Interior Decoration

Applicable Scenarios: Partition walls, ceilings, and interior panels of ship cabins; interior decoration (walls, ceilings) of high-speed rail/subway carriages.

Core Advantages:

Strong weather resistance, UV and rain resistant, not easily aging;

Inorganic material, acid and alkali resistant, non-rusting and non-rotting;

Fire-safe, avoiding fire hazards of outdoor facilities.

Recommended Types: 15-18mm heavy MgO boards (requiring anti-corrosion coatings to enhance weather resistance).

 

Other Extended Applications

Temporary Buildings: Prefabricated houses, construction site dormitories, and emergency disaster relief shelters (walls and ceilings)-advantages include fast installation, fire safety, and recyclability.

Stage and Exhibition Construction: Temporary stage backdrops and exhibition booth partitions-advantages include lightweight portability, quick assembly and disassembly, and fire safety.

Pet Cages and Breeding Facilities: Pet cage substrates and breeding shed partitions-advantages include moisture and insect resistance, easy cleaning, and non-toxicity.

 

Core Summary of Application Scenarios

The core application logic of MgO boards is "matching product characteristics with scenario needs":

Fire safety requirements → Priority use for firewalls, fire doors, and ceilings/partitions in public spaces;

Moisture and waterproof requirements → Focus on toilets, basements, cold storage, and ships;

Lightweight and high-strength requirements → Suitable for high-rise buildings, transportation vehicles, and temporary buildings;

Cleanliness and environmental protection requirements → Focus on hospitals and food/electronic cleanrooms.

Their "multi-purpose" feature makes them a "universal board" in construction, industry, decoration, and other fields. Especially in scenarios requiring both fire protection and moisture resistance, they are an irreplaceable preferred material.
