Armstrong Xiamen Product Seminar was held on September 16^th, 2004. Participants included architects, owners and main contractors. During the seminar, Armstrong shared a lot of useful information with the participants, for instance, the unique attributes of Armstrong product, new product information and project references all over the country. At meanwhile, participants were invited to do experiments to experience the outstanding advantage of Armstrong's ceiling and grid products. Most of the participants were very active and enjoyed a lot! The interactive way of communication helped participants to gain more product knowledge. The seminar was very successful.
