Greenstone Introduces MagneLine(R) StairSaf-T(TM) Anti-Skid, Anti-Corrosion Coating

NEW YORK, NY announced today that the Company has introduced a new product MagneLine® StairSaf-T(TM) which is an innovative method to utilize specially designed Polymer Cement Mortar to protect metal stairs such as fire escape and ladders on high-rise buildings and pedestrian crossing bridges, from rust, corrosion, and also to add traction making it harder to slip under slippery conditions.

"There are thousands of fire escape stairs and pedestrian bridges in our major cities which are not protected from the weather and StairSaf-T(TM) will make them last longer and be safer for the travelers," said Sal Miwa, CEO of Greenstone.

MagneLine is distributed exclusively in the United States by Greenstone for Magne Corporation in Fukuoka, Japan. See an example at http://www.egreenstone.com/documents/StairSaf-Tapplicationexample.pdf.
