Product Introduction
High Strength Mgo Board Cost Magnesium Wall Sheathing Exterior Cladding Moisture-proof MgSO4 Panels
High Strength MgO Board and Moisture-proof MgSO4 Panels are highly competitive new inorganic environmental protection panels in the current construction field, especially widely used in magnesium wall sheathing and exterior cladding scenarios. Both are made from natural minerals as core raw materials through advanced processes. Compared with traditional wood, gypsum and cement-based panels, they have achieved comprehensive upgrades in core performances such as strength, moisture resistance and fire resistance, and are suitable for diverse construction needs, making them the preferred materials for green buildings and efficient construction.
Advantages of MGO Board
1. Super strong and durable. They're way stronger than regular gypsum boards, even when wet. They're also lightweight but tough, can take impacts well, don't age easily, and last over 50 years. Even on exterior walls, exposed to wind, sun and rain, they won't deform, crack or get damaged.
2. Great at resisting moisture and corrosion-perfect for tricky environments. This is what makes MgSO₄ panels stand out, especially for exterior walls and damp spots. Unlike old MgCl₂ boards that get damp, form white residue and corrode metal parts, our MgSO₄ panels have no chlorine, don't absorb much moisture, and won't damage steel structures. They also resist mold, insects and termites, and work great in coastal areas, basements or bathrooms.
3. Top-level fire resistance (Class A1). They're made of inorganic minerals-no flammable stuff. If there's a fire, they won't burn or give off toxic fumes, and can hold up for over 3 hours. They help block flames, keeping people safe, which is perfect for busy places like malls, schools and hospitals.
4. Green and easy to work with. All raw materials are natural minerals-no harmful chemicals like formaldehyde. They're eco-friendly, low-carbon, and can be recycled. They're also easy to cut, drill and sand, like wood. The surface is smooth, so you can paint or tile right on it. They're light, easy to transport and install, saving time and labor.

High Strength Mgo Board Cost Magnesium Wall Sheathing Exterior Cladding Moisture-proof MgSO4 Panels
1. Core Substrate Composition (Outdoor-Adapted Formula)
- Main Binding Material: High-activity magnesium oxide (MgO) with a purity of ≥88%, selected for its stable chemical properties and strong gelling ability. It forms a dense crystalline structure after curing, laying a foundation for fire resistance and structural strength.
- Gelling System: Modified magnesium sulfate solution (instead of ordinary magnesium chloride) is used as the gelling agent, combined with professional anti-halogen and anti-efflorescence additives. This effectively prevents surface whitening, salt precipitation and structural damage caused by outdoor temperature changes and moisture erosion, solving the common problem of halogen return in traditional MgO boards.
- Reinforcement Material: Double-layer embedded alkali-resistant glass fiber mesh cloth (with a mesh size of 4x4mm) and micro-polypropylene fibers. The mesh cloth enhances the board's flexural and impact resistance, while the micro-fibers inhibit crack generation, ensuring the 12mm thin board does not break easily during transportation and installation.
- Functional Fillers & Modifiers: Mixed with high-hardness quartz sand, fly ash and weather-resistant modifiers. Quartz sand improves the board's wear resistance and load-bearing capacity, fly ash optimizes the material density to achieve lightweight effects, and weather-resistant modifiers enhance UV resistance and aging resistance, adapting to long-term outdoor exposure.
2. Specialized Production Process for Exterior Wall Partition
The production process is customized for the 12mm thickness and exterior application scenarios, focusing on precision molding and durability enhancement:
- Precise Batching & Slurry Mixing: Raw materials are proportioned by weight with an error of ≤±1% to ensure the consistency of slurry performance. The mixture is stirred at high speed to form a uniform, bubble-free slurry, which is the key to ensuring the density and strength of the thin board.
- Layered Molding & High-Pressure Compaction: The slurry is evenly poured onto the production line, and the glass fiber mesh cloth is embedded in layers. A high-pressure press (pressure ≥12MPa) is used for compaction to eliminate internal pores, ensuring the 12mm board has uniform density and no hollowing.
- Constant Temperature & Humidity Curing: The board is cured in a constant temperature (35-45℃) and humidity (60-70%) workshop for 48-72 hours. This ensures complete hydration reaction of magnesium oxide and gelling agent, avoiding deformation and cracking caused by incomplete curing in outdoor environments.
- Double-Sided Surface Treatment: After curing, the board undergoes double-sided sanding to ensure flatness (error ≤2mm/2m). Then, a layer of inorganic anti-aging coating is applied to enhance weather resistance, UV protection and water repellency, making it directly applicable to exterior wall construction.
- Strict Quality Inspection: Before leaving the factory, each batch of boards undergoes tests on fire resistance, water absorption, flexural strength, weather resistance and anti-halogen performance. Only products that meet national and industry standards are allowed to be shipped.
Main Application Scenarios
With excellent comprehensive performance, both types of panels are widely used in residential, commercial, industrial, rail transit and other fields of construction, among which exterior wall sheathing and cladding are the core application scenarios:
1. Exterior Wall Sheathing (Magnesium Wall Sheathing)
It can be directly used as the structural sheathing of building exterior walls, replacing traditional fire-treated wood, cement boards and gypsum boards, and is suitable for various building main bodies such as steel structures, wood structures and concrete structures. It can provide stable base support for exterior wall decorative layers (coating, stone, metal panels). Its high strength can resist wind load impact, and its moisture and fire resistance can protect the building main body from rain erosion and fire risks, especially suitable for exterior wall projects in coastal, rainy and high-humidity areas.
2. Exterior Cladding
Due to its excellent moisture and corrosion resistance and weather resistance, MgSO4 panels are more suitable as exterior cladding materials, which can be used directly or after decorative treatment on the surface of building exterior walls, with both decoration and protection. In prefabricated buildings, it can be compounded with thermal insulation materials to form an integrated exterior wall system, realizing multiple functions such as thermal insulation, fire resistance, moisture resistance and decoration, with efficient construction and stable overall performance.
3. Other Extended Applications
In addition to exterior wall scenarios, both types of panels can also be used in interior partitions, ceilings, fire partitions, floor substrates, clean workshop enclosures, ship and rail transit interior decoration and other fields. Among them, due to the chlorine-free and corrosion-resistant characteristics, MgSO4 panels are more widely used in humid environments such as basements, bathrooms and kitchens, as well as in the enclosure systems of steel structure buildings; high-strength MgO boards are more suitable for indoor and outdoor scenarios with high strength requirements and relatively low humidity.
Core Definitions and Component Differences
Both types of panels belong to the magnesium building material system and contain high-purity magnesium oxide (MgO) as the core component, but there are essential differences in their bonding systems, which also determine the differences in their performance focus and applicable scenarios:
1. High Strength MgO Board
Taking high-purity magnesium oxide as the base material, traditional formulas mostly use magnesium chloride (MgCl₂) as the binder, while modern high-end products have gradually optimized the formula, and some adopt chlorine-free systems; at the same time, wood fiber, perlite, glass fiber mesh and non-woven fabric and other reinforcing materials are added, and formed through mixing, pressing, curing and other processes. Its core crystal structure is a magnesium cementitious system, which endows the panel with excellent mechanical properties and structural stability.
2. Moisture-proof MgSO4 Panels
As an upgraded product of MgO board, the core improvement lies in replacing magnesium chloride with magnesium sulfate (MgSO₄) as the binder, which reacts with magnesium oxide to form a stable 5·1·8 phase crystal structure (5Mg(OH)₂·MgSO₄·8H₂O). This formula completely solves the pain points of traditional magnesium oxychloride boards such as easy salt efflorescence, sweating and metal corrosion, and its stability in high-humidity environments is significantly better than that of traditional MgO boards. It is an exclusively suitable panel for humid scenarios and steel structure buildings.
