ROCKMAX is one of the leading MGSO4 panel in China

Today mgo board plays an important role in fireproof building materials industry.

Because fireproof,impact and flexibility performance of mgo board is better than fiber cement board and gypsum board, moisture,termite and mildew resistant is better than wood panel.


Rockmax has been research and design magnesium oxide cement over 11 years,there are some experiences for share:

  • Most of mgo board are limit to use in low humidity environment, because original mgo board is air harden materials,it’s water safe, but not waterproof.
  • Mgo board’s product category belongs to cement bonded wood particle board(CBPB), and all the CBPB’s wet expansion rate is larger than fiber cement,lower than wood panel in heat and wet recycle environment. Mgo board is next generation CBPB,lighter,higher strength and better fireproof.
  • Only few of reinforced mgo board has been tested and approval to use in wet application, but still need to check wet expansion before design.

How to certain a mgo board can use in wet application?

  • Need to check durability result under En 12467/ASTM C 1186, strength remain should > 0.75
  • Minimize wood particle volume, make sure of low water absorption and wet expansion rate close to fiber cement.

How to aviod risks of purchasing wrong MGO board?

  • Purchase from certified distributor or factory, which got BBA/ CE or UL/ETL/CCRR approval
  • Find a professional MGO board consutant company,control manufacturing process and final inspection.

Mgo board problem and solution

Today mgo board plays an important role in fireproof building materials industry. Because fireproof,impact and flexibility performance of mgo board is better than fiber cement board and gypsum board, moisture,termite and mildew resistant is better than wood panel.

Mgo Board Problem

Mgo board is a innovative fireproofing building materials, it is popular for superior fire resistant, low heat transfer, high strength and economical efficiency. Now BBA, LABC, CCMC, CERT MARK, University of Denmark and St. Petersburg  warned some of mgo board contains chloride which has risk of corrosion to steel frame and damp insulation materials in humidity environment, damage adjoining building components.

How to prevent avoid mgo board damage wall?

Don’t purchase cheap mgo board, 99% of cheap mgo board are made from magnesium chloride.
If you have purchased corrosive mgo board already, suggest to compensate for replacement or seal the board entirely and use stainless screw.

Fire Resistant MGO Board and its Wide Benefits for Home Renovation

Magnesium Oxide board "MgO board" is an industrial facility made, non-protecting sheathing board item. It tends to be utilized for various applications including divider and roof linings, sashes, soffits, tile support and underlayment. It is made of magnesium oxide, a sort of mineral concrete, and is ordinarily called essentially "MgO" (articulated emm-well gracious) because of its compound organization of magnesium (substance image Mg) and oxygen (concoction image O). 

 Consider MgO a kind of sheathing board (similar to drywall or concrete board) however with much improved attributes, for example, imperviousness to fire, climate capacity, quality, protection from form, buildup, etc.

MgO is accessible in numerous structures, and for building development comes in different thicknesses and sheet sizes. It additionally comes in different evaluations, for example, smooth completions, harsh surfaces, and utility evaluations. It is white, beige or light dark in shading, and has a "hard" stable when sent a clear message to some degree like Portland concrete board.

There are many organizations that make MgO board, the greater part of which are in Asia. There are a few huge makers, however most are little neighborhood makers who serve an area. Notwithstanding the base material of MgO, different sorts of magnesium 'concretes', wood flour, and different added substances are incorporated to improve assembling and upgrade different properties.

Most fire resistant board has some kind of sinewy support inside the center or potentially on the face. Frequently this appears as glass work, filaments, or a fine tirade. MgO sheets likewise contain different added substances to upgrade adaptability and climate capacity. 


 At the end of the day, there are different kinds of MgO sheets; however, most are basically the equivalent as far as their essential piece. MgO sheets are made as individual pieces that are sliced to length as they are poured onto a throwing plate. The underlying set happens on a level plane; however, the last fix happens vertically or with spacers between the sheets.

The MgO is thrown in a fluid slurry-like structure (a blend of MgO powder, and different added substances and water) and sets up by synthetic response - much like Portland concrete does in plaster or cement. The cast sheets are then relieved at surrounding temperature. MgO sheets don't contain asbestos, yet some have various kinds of miniaturized scale fiber fortifying. This strengthening is discrete from the surface scrim, and is a piece of the MgO board used to cast the MgO sheets.

What is ROCKMAX’s suggestion for magnesium board market?

In order to rebuild market confidence,ROCKMAX suggest

Distributor need to have a deep understanding the technical level of your mgo factory
make sure of what level of mgo you are selling,and what kind of application is going to use.
because mgo board has different type and different quality level.

Basiclly has 3 type,

  • magnesium oxychloride hydrate
  • magnesium oxysulfate hydrate
  • magnesium oxyphosphate hydrate

The difference is they are formulated with different kind of salt. Different quality level mgo should put in appropriate place.

The designer,should understand exterior wall panel need strength remain above 0.75 and low water absorption rate,There is no exception for mgo board.If they can’t meet international standard,do not suggest to use as exterior render.

The builder need to check durability and chloride content report before installation. Some branded high density mgo board has full certificate,but they don’t have chloride content report.

It may corrode steel,especially in wet environment,we suggest to use wood frame and stainless screw instead. otherwise hold the bag and don’t know why.

The end users should understand mgo board without full durability certificate,can’t be use for exterior wall.No matter how attractive for price and physical performance you got
