(4) no cement grout and resin cartridge needed.
(5) available with both black and galvanized.
It is based on the request of each client.
Tightlok cable bolt is made of steel strand, and has perfect support capacity. Usually be used in the area where common grouted support is vacant or inadequate, and especially good for permanent ground support with some resin cartridge . Features: 1. Has incomparable flexible capacity and anti-shearing capacity. 2. Available in two different diameters with both black and galvanized. 3. Usually packed into roll to save working space, especially in confined areas. 4. Can use the conventional bolting equipment. 5. Specially designed birdcage system can greatly improve the resin mixing and anchorage result. 6. Plain or bulbed options available, bulbs available at either 0.5m or 1m spacing. 7. Fish hooks fitted to cables for retention in holes prior to grouting. 8. Usually matched with Washer, Grip(Barrel & Wedge) and Dome Plate. It is based on the request of each client.
Tightlok grooved bolt is made of hot rolled bar with several forged grooves at one End, usually used for hardrock support. Features: (1) Groove device makes resin mixing easily and completely. (2) Fast and easy installation by mechanized tools. (3) Used together with resin cartridge for permanent support. (4) With pin nut device, nut can help drive the rod to mix the resin. It is based on the request of each client.
Tightlok threadbar bolt is composed of hot rolled ribbed bar, high strength plate , damping nut , yield tube, washer , and other accessories. Usually used in thick coal seams with very high stress and large Deformation. Features: (1) High tensile strength and good support capacity which can prevent the roof from sinking and sliding. (2) Fast and easy installation by mechanized tools. (3) Used together with resin cartridge for permanent support. (4) Sharp end device makes installation easier and faster. (5) Left hand thread direction available. (6) Specially "sandwich"device can buffer and release the pressure.
Full thread bar bolt is used together with dome plate and net for reliable ground support in mines, tunnels, slopes, or wherever. Feature: (1). The bar has closely defined mechanical properties which provide consistent performance under long term anchor loading. (2). In the longitudinal direcition , rock body has equal tensile strength , that is about 40% higher than the reverse-twist bolt in the same specification. (3). Extend the support area , not only be used by end anchoring , but also be used by fully anchoring , that has a better Support efficiency. (4). Low price, widely used in coal mines, railways, hydropower and other types of roadway projects. (5). Thread profile offers excellent mixing capabilities in resins installation. (6). The high ductility and smooth, relatively flat rate of strain hardening ensures a high margin of safety against tensile/shear overload in the case of transverse movements in the rock soil. (7). Can be cut and spliced at any point along its length. It is based on the request of each client.

Manufacturer & Supplier of Duplex & Super Duplex Bolts & Nuts & Duplex Stainless Steel Nut Bolt. Our product range also comprises of Hastelloy Bolts, Stainless Steel Fasteners and Foundation Bolts. Duplex Stainless Steel Nut Bolt Item Code: 2205 We are one of the topmost manufacturers, suppliers and traders of a wide range of optimum quality Duplex Stainless Steel Nut Bolt. Manufactured in adherence to the industry set norms, these products are known for their resistance to corrosion, fine finish and durability. For the purpose of ensuring a defect free range, these nuts and bolts undergo various quality assurance checks. Features Corrosion resistant Durable finish Accurate dimension Other Details Chemical Desalination Material handling Oil and Gas extraction Pulp and Paper Petrochemical Augers Cargo tanks Couplings Diaphragm seals Fans Fasteners Heat exchangers Hubs Instrumentation tubes Pipe fittings Press rolls Pressure vessels Rotors Screw conveyors Shafts Valve parts Roughly double the strength of standard austenitic stainless steels, designed to improve resistance in many applications such as chloride environments and sulfide stress corrosion A-479 Types Duplex 2205 (S31803) Duplex 2205 stainless steel (both ferritic and austenitic) is used extensively in applications that require good corrosion resistance and strength. At temperatures above 300°C, the brittle micro-constituents of this grade undergo precipitation, and at temperatures below -50°C the micro-constituents undergo ductile-to-brittle transition; hence this grade of stainless steel is not suitable for use at these temperatures. Duplex S32750 Duplex 2507 is a super duplex stainless steel designed for applications which demand exceptional strength and corrosion resistance. Alloy 2507 has 25% chromium, 4% molybdenum, and 7% nickel. This high molybdenum, chromium and nitrogen content results in excellent resistance to chloride pitting and crevice corrosion attack and the duplex structure provides 2507 with exceptional resistance to chloride stress corrosion cracking.
