Suspended ceiling fixing is one of the most common masonry fastening scenarios. Two mainstream solutions are widely adopted by ceiling contractors: drop-in anchor system and self cutting screw system.
Drop-in anchor is embedded into concrete slab first, then connect ceiling hanger bolt into the internal thread of anchor. This solution is suitable for medium and heavy load ceiling, with stable and reliable performance.
Self cutting screws can directly fasten hangers into concrete without anchors. It is faster for light and medium load ceiling jobs. Compare material cost, load requirement and construction speed before choosing ceiling fixing method.
