Expansion Bolts & Shields Manufacturing is a specialized industry within the broader category of Fabricated Structural Metal Manufacturing. This industry involves the production of expansion bolts and shields, which are used in construction and engineering projects to secure structures and equipment to concrete or masonry surfaces. Expansion bolts are fasteners that expand when tightened, creating a secure anchor point, while shields are used to protect the bolt from damage during installation. This industry requires a high level of precision and quality control to ensure that the bolts and shields meet the necessary safety standards and can withstand the weight and pressure of the structures they are supporting.
