San Shing Fastech Corp., the largest professional manufacturer of steel nuts in Taiwan said the company's December shipping volumes might drop further due to weak demand. Consequently, its December sales revenue will decline from a month earlier.

San Shing said about 59% of its business comes from European market and 35% is from North America; however, the unclear economic situation in those areas caused its sales go down in this Q4.

At the same time, San Shing said it still has available allocation for next Q1.

Nevertheless, the market analysts said San Shing's sales in whole 2011 will still increase more than 30% than in 2010.
