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

Export production capacity: 25 container per month (SIP skin)
B, Wuhu production base: 20000m²
Export production capacity: 50 containers per month
--- The alternative of OSB
ROCKMAX Magply is an extreme high strength magnesium sulfate board. It is made from compressed magnesium oxysulfate cement, high density mesh fiber, waterproof polymers and other reinforcement. Bending strength and screw holding strength similar to OSB, it is 100% formaldehyde free green product and fire resistant. An innovative fire resistant board for LFS racking wall and fire resistant SIP.

Other thickness and dimension can be customized.
We have our own Laboratory, and are able to do raw material evaluation, microcosmic chemical reaction inspection, physical performance evaluation, durability evaluation. We can research and design different density, strength, water absorption rate, panel's combination structure, insulation performance, and fireproof performance to meet multiple applications.
Rockmax factory equipped with latest high automatic equipment which help us staying leading status in the industry line.
We have comprehensive standard documents and familiar with testing procedure of GB / EN / ASTM / ISO standard, we can provide accordingly test report for each shipment.
Magnesium oxide board or "mgo board" in short, is a fireproof, waterproof, light weight, high strength, mildew and termite proof wall panel, with a thickness range from 4mm-30mm. It consists of 3 elements: magnesium oxide, salt, and crystal water.
Mgo board predominately comes in three different types depending on the salt used: magnesium oxychloride hydrate (which poses steel corrosion risks), magnesium oxysulfate hydrate, and magnesium oxyphosphate hydrate.
You can submit the board for a chloride content inspection to SGS. This standard testing procedure usually costs around $300-400 and takes approximately 7 working days to deliver the results.
ROCKMAX is a new generation chloride-free mgo board. It is entirely green, meeting the European "REACH" regulation by excluding 191 kinds of harmful substances. It features high bending strength (12mm > 25-30 Mpa), low water absorption (<10-15%), and high durability (Category A for semi-expose exterior walls).
Yes, ROCKMAX offers a 20 years warranty ensuring no steel corrosion and no moisture regain for final users.
Yes, while standard sizes include 12mm x 1220mm x 2440mm/2750mm/3050mm, other customized thicknesses and dimensions can be manufactured based on project requirements.
