Complete range of split set bolts, Swellex bolts, self-drilling anchors and cable bolts for underground mining and tunnel construction
Prestressing Anchor Wedge
The Prestressing Anchor Wedge is a key gripping component in post-tensioning anchorage systems. It locks prestressing steel strands inside the tapered bore of the anchor head. After tensioning is completed, the wedge works with the anchor head’s conical surface and grips the strand through its inner serrations, transferring prestressing force securely to the anchorage system and concrete structure. It is suitable for prestressed slabs, beams, bridges, and other post-tensioning applications, with matching options available according to the anchorage system, strand specification, and project requirements.
CT Rock Bolt | Special Combination Anchor Bolt for Hard Rock Roadway and Tunnel Support
CT anchor bolt is a special type of anchor bolt commonly used for supporting hard rock roadways, mine tunnels and underground engineering. It is suitable for rock stratum environments that require rapid installation and stable reinforcement. It usually combines mechanical anchoring and grouting reinforcement methods, enabling the quick formation of primary support on construction sites, and subsequent grouting can strengthen the bonding effect between the anchor bolt and surrounding rock. The product can be customized in terms of length, bolt body specifications, bearing plates, anti-corrosion treatment and other configurations according to project requirements, and is applicable to various rock mass reinforcement scenarios such as mining excavation, tunnel driving and underground chambers.
Lattice Steel Beam
Lattice steel beam is a type of steel structural component applied in industrial and mining support, steel structure connection and engineering load-bearing scenarios. Designed with regular hole positions and a lattice beam body, it facilitates on-site positioning, assembly and bolt fastening. Customizable in length, cross-sectional dimensions, hole spacing, plate thickness, material and surface finishing based on project drawings or sample requirements, this product suits multiple working conditions including mine roadway support, industrial factory buildings, equipment support and temporary construction shoring. Featuring neat structure and flexible installation, it allows bulk transportation and centralized on-site construction, serving as a commonly used auxiliary load-bearing component in industrial and mining projects as well as steel structure works.
Finished Rolled Coupler (Precision Rolled Rebar Connecting Sleeve)
Precision rolled coupler, also called rebar connecting sleeve, is dedicated matching connector for prestressed fine rolled rebar. Made of integrated forged alloy steel with heat treatment, it features high tensile resistance and easy installation without welding. Widely used in bridges, tunnels, slope support and all kinds of large infrastructure projects to realize equal-strength connection of prestressed rebars. Full standard sizes in stock, customized specifications and anti-corrosion treatments are available.
Flange Hex Tension Nut
This flange hex tension nut is integrally forged from alloy steel, featuring a thickened and heightened body together with an widened flange base and a precise full-thread structure. Subject to quenching, tempering and black oxide treatment, it boasts strong bearing capacity as well as excellent tensile and tension resistance. Compatible with finish-rolled threaded steel, anchor bolts and tension lead screws, it is widely applied to heavy-load tension scenarios including mine support, bridge prestressing, engineering machinery, tunnels and foundation pits. A full range of standard sizes are in stock, and customization of various non-standard dimensions and anti-corrosion processes is available.
Steel Strand Anchor Cable
Steel strand anchor cable is a prestressed anchoring product twisted from multiple high-strength low-relaxation steel wires, commonly adopting the 1×7 structure with a tensile strength grade of 1860MPa. It features high bearing capacity, low stress loss, flexibility and easy construction. It restrains surrounding rock deformation by actively applying prestress, and is widely applied in geotechnical reinforcement projects including mine roadways, tunnels, slope treatment and deep foundation pit support. Matched with anchors, bearing plates and grouting systems, it can form a complete support scheme to effectively enhance rock mass stability and engineering safety factor.
