Introduction
SIRIWAN PLASTICS CO.,LTD.
 We have been producing concrete form made from recycled polyethylene since 1998. Our products are very suitable for construction of concrete beam and column. It is so tough that it can be reused for more than 100 times, actually much more if used continuously. 
In 2005 we started foamed concrete business, importing foaming agent from UK. We were able to build foam generator with help of the foaming agent supplier. Also we have invented excellent mold system for foamed concrete blocks. 
In 2008, mold system for making precast concrete fence post and panel was proudly invented and patented in Thailand. The precast fence elements made from this mold system is very neat, light in weight and very easy to install.
