This is not the forum for looking for suppliers. If you have a need post a buying, or selling   lead under My Alibaba for a supplier or a buyer.  If you wish to discuss materials used in construction.  Direct your questions to the "Building Materials" forum.  However, do not post personal contact information as this is a forum policy and regarded as a trade lead.  Any such post in the nature as the one above will be considered a trade lead which could cause you to loose the privlege of posting on all forums.
