Self drilling hollow bar provides higher tensile strength

Self drilling hollow bar is used to attach objects or structures to concrete. There are many types of this kind of hollow bars, consisting of designs that are mostly proprietary to the manufacturing companies. All consist of a threaded end, to which a nut and washer can be attached for the external load. Sinorock self drilling hollow bar has been developed using a pumpable resin system for full column resin encapsulation for immediate roof and rib support. A new drilling and injection system has also been developed to enable fast and efficient bolt installation.

Sinorock self drilling hollow bar provides higher tensile strength than conventional solid bolts, and also provides a load transfer capacity that is almost double that of conventional bolts. It uses low viscosity pumpable resin to ensure full encapsulation right down to the collar. Sinorock works hard to be a reliable and satisfactory service provider for anchor bolt systems design and supply. A satisfactory service is recognized as the means of offering complete technical support to our clients with maximum flexibility in production and the fastest possible delivery times. With approximately 10.000sqm area of production halls, Sinorock is equipped with more than 100 work stations and has a monthly production capacity of approximately 300 tons.
