Product Overview


Our Company


ROCKMAX is a technical company,engage in researching and applying MOC technology in different region.

ROCKMAX laboratory provide chloride free technical support for over 10 mgo board factories in China.Now we focus on manufacturing structral use fireproof board for oversea SIP producer.We are good at analysis and evaluate various raw materials,upgrade production process,final product durability assessment.

ROCKMAX delicated to research chloride free mgo board over 10 years, with capicity of 70 containers per month. We are aiming to supply a safe mgo board for building industry.Now we are able got rid of chloride ion by new technology and provide 20 years warranty "no steel corrosion and no moisture regain" for final user.

What's mgo board?

Magnesium oxide board or "mgo board" in short, It is fireproof, waterproof, light weight, high strength, moldew and termite proof wall panel, thickness range from 4mm-30mm, It consist of 3 element, magnesium oxide, salt and crystal water.

Mgo board predominately come in three different types:
-magnesium oxychloride hydrate(steel corrosion risks)
-magnesium oxysulfate hydrate
-magnesium oxyphosphate hydrate
They are formulated with different kind of salt.
Chinese magnesium oxide board industry association issued new industry standard for export mgo board.
All the mgo exporter have to indicated limitation in specification, that chloride mgo shall not be directly contacted with metal parts without rust treatment

How to check chloride content of mgo board?

Submit chloride content inspection in SGS, cost $300-400 and takes 7 working days

What is advantage of ROCKMAX mgo?

-ROCKMAX is new generation chloride free mgo board, test in full
-ROCKMAX mgo is entirely green product, material safety meet European "REACH" regulation, exclude 191 kinds of harmful material may effect health.
-ROCKMAX mgo has outstanding physical performance
.Maximum strength 8mm> 30-40 Mpa, 12mm > 25 – 30 Mpa
.Minimum low water absorption rate <10-15%
