Company Introduction

Welcome to Hezhou Topking Rock Drill Equipment Co., Ltd. (Brand: Expandag).

Formerly known as Hezhou Topking Chemical Co., Ltd., we have upgraded our company name in 2025 to better reflect our complete range of mining solutions. Established in 2012, we are a leading manufacturer specialized in researching and producing both Expansive Mortar (HSCA) and pneumatic Rock Drills.

1. Core Product: Expansive Mortar (Soundless Cracking Agent)
With over 20 years of experience, we introduce advanced formulas to produce high-performance Non-Explosive Demolition Agents. Our "Expandag" powder offers high expansion pressure and controlled reaction time. It is the ideal alternative to explosives for:

Granite and marble quarrying (No waste of stone)

Concrete demolition & removal (No noise, No vibration)

Environmentally sensitive projects

2. Mining Machinery: Rock Drills & Tools
To provide a one-stop solution for our clients, we also manufacture heavy-duty pneumatic rock drills (models Y24, YT28 Jack Hammers) and drilling consumables such as Tapered Drill Rods and Button Bits.

Global Reach: Our products are widely exported to Brazil, India, Egypt, Europe, and Southeast Asia. Our principle is "Quality First, Customer Priority". We warmly welcome distributors worldwide to join us for a Win-Win partnership.
