Steel-Faced Magnesium Fire Board

Product Overview

It adopts single-sided or double-sided color steel as the surface layer, with magnesium oxysulfate board as the core material. As a new eco-friendly product for fire smoke exhaust systems, it outperforms conventional smoke exhaust ducts. This product features excellent fire resistance, fire endurance, water resistance, bending resistance, heat insulation and sound insulation. It is also non-toxic, lightweight, aesthetically pleasing, and easy to manufacture and install with simple construction processes.

Product Uses

It is mainly used for basement fire smoke exhaust systems in various projects, and can also be used as exhaust ducts for fresh air systems. It is suitable for smoke exhaust and ventilation applications in large-scale projects such as hotels, shopping malls, hospitals, stadiums, etc.

Features

Composite Process

 The steel-faced magnesium fire smoke exhaust duct adopts the composite process of magnesium oxysulfate board and color steel, which effectively meets the fire resistance and fire endurance requirements of fire smoke exhaust ducts.

Fire Resistance 

The production process of the steel-faced magnesium fire smoke exhaust duct consists of a composite core material and surface layer. The core material is made of non-combustible Class A1 inorganic material, and the surface layer is composited with color steel plate via adhesive bonding, giving it excellent fire resistance. Tests have proven that it has a fire resistance capacity exceeding 1200°C. Certified by the National Center for Quality Supervision and Testing of Fire Building Materials, the duct meets the requirements of fire safety standards GB 8624-2006, GB/T 20285-2006, and GB/T 5464-2010.

Thermal Insulation 

The core material of the steel-faced magnesium fire smoke exhaust duct uses fire-retardant thermal insulation particles as filler, providing effective thermal insulation. According to fire endurance tests, when the external temperature exceeds 1000°C, the internal temperature of the duct remains stable below 180°C.

Corrosion & Acid Resistance, Non-toxic 

The core material of the steel-faced magnesium fire smoke exhaust duct is composed of inorganic mineral materials, offering excellent corrosion and acid-alkali resistance. This ensures the duct will not deform or weather even in humid basement environments.

Superiority

 The composite of color steel plate and magnesium oxysulfate board solves key challenges in current fire smoke exhaust systems:

• Traditional galvanized steel ducts cannot meet the 2-hour fire endurance requirement for smoke exhaust systems.
• Galvanized steel ducts have no sound absorption performance, requiring additional silencers.
• They have high thermal conductivity and lack thermal insulation properties, requiring extra insulation layers.
• They are unsuitable for use in highly humid environments, where they are prone to corrosion and rust.The magnesium oxysulfate core material addresses thermal insulation, sound absorption, and fire resistance, and the composite structure perfectly solves all these problems.

Sound Insulation & Absorption

 The magnesium oxysulfate core material has a crystalline structure that absorbs noise generated during duct operation and reduces resonance.

Bending Resistance 

With exceptional bending resistance, the composite of magnesium oxysulfate core and color steel combines the toughness of color steel with the rigidity of the core material, perfectly demonstrating its outstanding bending resistance.
