Pleasanton, Calif.-based Simpson Manufacturing's first-quarter net sales increased 7.0% to $132.5 million compared with the same quarter last year.
Net income declined 23.1% to $7.08 million, down from $9.20 million in the same three-month period of 2010.
The company said sales to contractor distributors, dealer distributors, lumber dealers and home centers increased in the quarter, despite economic conditions it described as "challenging." Sales of anchor products and shearwalls also increased over the same period.
