Stalwart Technosource India Pvt Ltd. are the only manufacturer that caters clients with tailor requirement for mechanical properties and physical dimensions. We manufacture shear stud with Brand name "Stalwart" and "ST" make as per client specifications and customisation. We have an extensive variation in Tensile Strength, Yield Strength and Elongation to meet clients demand based on requirements. We are approved by Railways, NHAI,NTPC, L&T, IRCON and Many More. We are the major supplier of Shear Stud for Railway Bridges & Power Plant in India. Shear Stud Design & Mechanical Properties Shear Stud Connector Shall be manufactured from cold drawn Wire Rods confirming to the requirements of ASTM A 29 of grade designation SAE 1010 through SAE 1020 or equivalent, inclusive either semi-killed or killed (aluminium or silicon de oxidation). Mechanical properties & other requirements of studs shall confirm to the requirements of Type-B studs specified in AWS Dl.1/D1.lM or equivalent. Stalwart studs for welding with ceramic ferrules are provided with an aluminum tip as required by the welding process to facilitate the ignition of the arc, to stabilize the arc and to deoxidize the welding pool. The correct amount of flux used is an essential factor in obtaining perfect welding results.   Code of Practises BS EN 13918:2008 Welding Studs & Ceramic Ferrules for Drawn Arc Stud Welding. IS 3935 Code of Practice for Composite Construction. BS 5400 British Standard Code of Practice for Composite Bridges. Important Advantages of Shear Connectors Cost-effective production in large quantities and many different sizes. Reliable and safe under static and dynamic stress. Mechanical interlock of steel and concrete - lifting-off of concrete slabs is prevented. High ductility considerable increase in bearing capacity through plastic design. Anchorage of steel parts in concrete for various load directions, no cracking forces because of mechanical interlock. Individual design of reinforcement by pre-planned positioning of steel members in concrete. Firm welds produced by stud welding. Application by trained operators - no highly qualified welders required. Electronically controlled and monitored Drawn Arc Stud welding equipment ensures repeatability and verifiable quality of the weld.

Stalwart Technosource India Pvt Ltd is a leading manufacturer and supplier of Fasteners & Shear Studs & has its expertise in ROB for Railways and supplies to RDSO approved projects across India with Brand Name: "Stalwart" and "STIPL" Stalwart Technosource India Pvt Ltd. meets all the specification and Codes of practices of Railways. We have a team of expert professionals who are highly qualified and experience manufacturing these products by using premium quality materials and according to the specifications of the clients. Our organization is supported with a capacious infrastructure facility that is equipped with advanced machinery, in House Heat Treatment and testing facilities. Our High Strength Friction Grip Bolts (HSFG) bolts are high strength structural bolts which have been tightened such as to induce tension in the bolt shank. Due to the tension in the bolt, the interface between the plies (steel members in a joint) cannot move relative to each other. Our High friction grip bolts are commonly used in structural steelwork. They normally consist of high tensile strength bolts and nuts with washers. The bolts are tightened to a shank tension so that the transverse load across the joint is resisted by the friction between the plated rather than the bolt shank’s shear strength. Product Range Nuts Bolts Studs Washers Threaded Bars Screws Rivets Other Fasteners Advantages of Stalwart HSFG Hardware: HSFG bolts have the following advantages when compared with normal bolts: The performance of preloaded HSFG bolts under fatigue loading is good because the prestressed bolts are subjected to reduced stress range during each loading cycle when compared with unloaded bolts. For structures adjacent to machinery which generate substantial vibration, preloading bolts can help to avoid the loosening of bolts. HSFG bolts are used in connections where any slight slip movement would render the integrity of the whole structures break down. Owing to its high tensile strength, it is commonly used in connections which require the taking up of high flexure and the tensile stress generated could be readily resisted by it high tensile strength.

Ceramic Ferrules for shear connectors Stud welding. Standard: BS EN ISO 13918 Type UF for weld shear connector to steel remembers directly. If you need for weld shear connector through metal deck. Ceramic Ferrule is necessary part for shear connector Stud welding process it designed by the following functions: Protection of the weld pool by creation of metal vapour in the burning chamber at sufficient current intensity. Concentration and stabilization of the arc thus reducing arc blow. Moulding of the displaced weld pool to a weld collar and supporting of the weld pool. Furthermore it shields the operator from both arc and spatter. The ceramic ferrule is used for one weld only and is removed once the molten metal has solidified.   Stalwart Technosource India Pvt Ltd. ceramic ferrules with high precision size and low water absorption rate can significant improve the weld result.
