Onekin green board, which is also called magnesium board or mgo board or magnesium oxide board, is a technology that also developed a lot of years,much longer time than Onekin green panel.

Different from other manufacture, Onekin green mgo board not only concentrate on high quality raw materials, but also high the production machines, high efficiency machines also decide the quality of boards. We have secondary mixing system for the raw materials which is very expensive invest, just mix the raw materials sufficiently, and makes the quality balance to every board area and every piece.

For fiber glass mesh, we also use about twist weaved mesh 200g-250g/sqm, while other manufacture use plain weaved under 100g/sqm. Fiber glass mesh quality will decide the strength of the board.

During our construction, we use 10mm or 12mm as internal wall or external wall backer board, and 18-25mm as flooring backer board, 8mm or 10mm as roofing backer board. The backer board are only be used for the structure of the house, for decoration, you need extra materials, so once you doing the ceiling, you need ceiling board, and flooring, you need ceramic tile or wood floor, for wall, you need decoration wall cladding board or ceramic tile.


This is light steel structure, which same way with fiber cement board, gysum board and calcium silicate board, which is different way for construction of Onekin green wall panel system.

Flooring backer board are not only thicker, but also stronger since add strengthen materials during production.
