Henan ZongXiang Heavy Industry Import & Export Co., Ltd., a leading Chinese manufacturer and exporter of mining support products, has recently completed a major export shipment of 5,000 pieces of high-quality 39mm split set stabilizers to Colombia. This transaction underscores ZongXiang's growing presence in the South American mining market and its commitment to providing reliable ground support solutions for underground operations worldwide.

What Are 39mm Split Set Stabilizers?

Split set stabilizers, also known as friction bolts or friction rock bolts, are essential tools in underground mining and tunneling. The 39mm variant (often referred to as SS-39) features a nominal outer diameter of 39mm and is made from high-strength steel tube with a longitudinal slot along its length. One end is tapered for easy insertion, and a welded ring at the collar end holds a domed bearing plate.

The working principle is straightforward yet effective: the stabilizer is driven into a pre-drilled hole slightly smaller than its diameter (typically using the same percussion drill that bored the hole). As it compresses, the slot narrows, generating radial pressure and friction along the entire contact length with the rock. This creates immediate frictional anchorage, stabilizing the surrounding rock mass in three dimensions—radial pressure on the hole wall, friction to prevent downward sliding, and compressive force via the plate.

Commonly used in coal, metal, and non-metal mines, these stabilizers excel in challenging ground conditions. They support roofs and walls, pin mesh screens, secure utilities like pipes and cables, and even stabilize highwalls in open-pit operations. The 39mm size is particularly popular for standard underground applications, offering a balance of strength and ease of installation compared to smaller (33mm) or larger (46-47mm) variants.

The company maintains large factory stocks, enabling rapid fulfillment of orders up to 50,000 pieces daily.

Quality is paramount: products meet international standards like GB, with options for black or galvanized finishes. Pull tests verify anchorage strength, and installation tools like dolly pushers ensure safe, efficient deployment. ZongXiang's ISO-certified processes and heat-treated alloy components guarantee durability in harsh mining environments.

The Export to Colombia: Strengthening Ties in South America

Colombia, with its thriving mining sector focused on coal, gold, and emeralds, demands robust ground support amid complex geological conditions. South America has long been a key market for ZongXiang, with frequent orders from Colombia, Peru, Ecuador, and others. Customs records show ongoing shipments to Colombian importers, reflecting trust in ZongXiang's reliable supply chain.

This latest export of 5,000 pieces highlights the company's ability to handle large-scale orders efficiently. Packaged securely for international transport, the stabilizers will bolster safety and productivity in Colombian underground mines. Similar recent exports include resin rock bolts and steel rails to the region, demonstrating ZongXiang's diversified portfolio.
