Green Sandstone Wallboard    Mega green sandstone wallboard is made of inorganic mortar on the top and ceramic board on the bottom (inorganic resin plate, i.e. fiber cement plate, also called calcium silicate board, is optional for internal wall) with Mega’s patented technology and advanced equipment, compounded under low temperature condition. It possesses texture and appearance of natural sandstone, and is free from stain, blackening, moldiness of natural sandstone caused by high water absorption. It is suitable for gluing, wet cladding and dry cladding.     1. Structure & Composition: Inorganic facing material (top layer), ceramic composite plate / Inorganic resin plate (bottom layer)
2. Standard Sizes: 300mm * 600mm * 8mm; 400mm * 800mm * 10mm ; 600mm * 1200mm * 12mm 
3. Max Width: 600 mm; Max Length: 1200 mm (customizable within this range); Thickness: 8mm - 12mm     
4. Certifications: CE / CSA                    5. MOQ: 1,000 SQM (or one 20’ Container)      Mega Wallboard Features   1. good alkali / acid resistance 2. good weather resistance (anti-thawing, anti-freezing) 3. stable dimension, low expansion rate, low contractibility 4. natural appearance, uniformed color 5. Durable, long service life 6. good stain-resistance, self-clean ability 7. Excellent fire-proof performance 8. easy to be processed 9. eco-friendly 10. easy installation    Performance Parameters of Mega Green Wallboards

Australian Sandstone VS Mega Sandstone
Feature	Australian Sandstone	Mega Sandstone
Texture and Color	Natural color and texture, but big color variation of the Sandstone from different stone mines,installation effect is not uniformed.	Natural color and texture, small color variation of the Sandstone from different boards, installation effect is uniformed
Stain resistance	A lot of pinholes make it high water absorption and easy to collect microorganisms, which cause it to darken or get moss, reduce its durability.	The surface is made of Inorganic facing materials,processed by Mega's patented techniques, giving it good self-clean and stain-resistance capacity and durability
Installation	After cutting into boards, it's sandy and smooth,making it not suitable for gluing for safety concerns, but high cost for dry cladding.	Mega's Sandstone board is made of Inorganic facing material compounded with ceramic composited plate as a base. The embossed base is strong, and suitable for gluing
Environment	Severe damage to the natural environment during the mining process.	No damage to the Nature as it is not exploited from stone mines
Price	High price due to the high cost of mining and low yield rate.	Money efficient and affordable due to mass production and lower comprehensive cost
