Sahm Welding and Fabrication, Washington, will complete an expansion in April to mark the company’s 30th year of operation.

President Mark Sahm said the expansion will include 6,500 square feet of manufacturing and 1,500 square feet of office space.

The additions are being made to the south and west side of the building.

Sahm welding specializes in light Structural work, sheet metal fabrication and custom equipment.

“We’re adding some new equipment and moving some things around,” Sahm said. “Mainly, we’re expanding our welding area.”

The expansion will give employees on the development side of the business more room to work, he said, and also will create three to four new jobs.

Sahm Welding and Fabrication opened for business March 1, 1987, and is located at 6337 Bluff Road.
