4metal deck anchors. Chemical anchors Chemical anchors rely on a chemical reaction between the anchor and the concrete to create a strong bond. They are commonly used in situations where pre-drilling is not possible or when additional holding power is required.

Expansion anchors are designed to expand when the resin cures, providing a strong hold in soft or friable substrates such as concrete or masonry. Plug anchors, on the other hand, rely on friction to hold the blockwork in place and are suitable for harder substrates such as brick or stone. Screw anchors are similar to plug anchors but have a threaded shank that allows them to be tightened to provide a more secure hold Screw anchors are similar to plug anchors but have a threaded shank that allows them to be tightened to provide a more secure hold Screw anchors are similar to plug anchors but have a threaded shank that allows them to be tightened to provide a more secure hold Screw anchors are similar to plug anchors but have a threaded shank that allows them to be tightened to provide a more secure holdresin anchors for blockwork.

When used together, wedge anchors and bolts form a powerful combination for enhancing construction stabilitywedge anchor bolt. For instance, when installing a beam or column, a bolt can be inserted through pre-drilled holes in the beam and column, and then secured with a wedge anchor. The wedge anchor expands and grips the surrounding material, providing a strong bond between the beam and column. This results in a more stable structure that can withstand greater loads and forces.
