Gilson Company

In 1939 Gilson introduced the first testing screen to improve the quality control of aggregates to be used in the proposed national interstate system. Since then, our sole focus has been to provide rugged and reliable testing equipment that deliver accurate results in a variety of applications. After more than 80 years of responding to the needs of the construction industry, Gilson has established itself as a worldwide authority and trusted source for high-quality materials testing equipment for aggregate, asphalt, concrete, and geotechnical applications.
We are proud to be in our 3rd generation of family ownership, and we remain steadfast in providing innovative products of uncompromising quality with an emphasis on exceptional technical support and customer service. 
Gilson customer service specialists are a team of associates with more than 125 years of combined experience in fulfilling our customers’ testing equipment needs. In addition, our technical support team is comprised of geologists, civil engineers, and former lab managers with industry experiences totaling over 100 years of performing laboratory and filed tests, assisting customers with product selection, repair parts, installation, equipment operation, and understanding the ASTM and AASHTO specifications. Our customer service and technical support teams are trained to be your partner. We understand the value of industry involvement and actively participate in developing, reviewing, editing and modifying AASHTO and ASTM standards.
Our recent 16,000 square foot expansion has allowed us to grow our engineering and manufacturing capabilities even more. The new facility also increased our inventory space and streamlined our delivery process which allows us to better meet our customers’ testing equipment needs.
