Hezhou Topking Rock Drill Equipment Co., Ltd.        (Brand: EXPANDAG)

Formerly known as Hezhou Topking Chemical Co., Ltd., we are a professional manufacturer of Expansive Mortar (HSCA) and Rock Drilling Machinery and Tools, with manufacturing and export experience since 2012. We provide full SDS documentation for international shipments and serve customers in more than 50 countries.

We work with three main types of buyers, each with a different starting question — here's how we fit each one:

Granite & Marble Quarry Owners — Explosives can damage valuable stone blocks and are increasingly restricted by local safety requirements. Our HSCA provides a non-explosive method for controlled rock splitting with no blast noise, no vibration, and no flying rock, helping quarry operators reduce blasting-related risks while protecting block value. Our HSCA can also be supplied together with compatible Pneumatic Rock Drills (Y24/YT28) and Tapered Drill Rods/Bits as an integrated drilling-and-cracking solution from one supplier.

Demolition Contractors — Urban and environmentally sensitive job sites may restrict the use of conventional blasting. HSCA provides a non-explosive method for controlled concrete and rock demolition, helping contractors reduce noise, vibration, flyrock, and the risk of disruption to neighboring structures.

Distributors & Importers — Buyers sourcing HSCA for resale or project supply need a factory-direct manufacturer with consistent product quality, full SDS documentation, and practical international shipping support. We provide standard export documentation and serve markets across the Middle East, Africa, South Asia, Southeast Asia, Europe, and South America.

Whether you are operating a quarry, managing a demolition project, or sourcing HSCA for distribution, our goal is to provide a reliable combination of product quality, technical support, and international supply. We welcome global distributors, contractors, and quarry operators to work directly with the EXPANDAG factory.
