As a result, we deliver factory-direct pricing, full weld traceability, and fast delivery. Similarly, this applies to all your cast-in-place concrete, precast, and steel-to-concrete connection projects.
In addition, we produce these embedded steel plate assemblies by welding headed shear studs to steel plates using the drawn arc stud welding process. Meanwhile, we comply with AWS D1.1 Structural Welding Code — Steel, and we use ASTM A108 headed studs as standard. Therefore, structural engineers and precast fabricators rely on them for transferring tension and shear loads between steel and concrete.
Technical Specifications of Concrete Embed Plate Assemblies
To begin with, we manufacture our embed plate assemblies in a range of plate sizes and stud configurations. Specifically, the table below summarizes the standard product range.
| Plate Size | Plate Thickness | Stud Diameter | Stud Length | Number of Studs | Typical Application |
|---|---|---|---|---|---|
| 100 × 100 mm | 8 – 10 mm | 13 mm (1/2″) | 100 – 150 mm | 4 | Precast wall panel connections |
| 150 × 150 mm | 10 – 12 mm | 16 mm (5/8″) | 100 – 200 mm | 4 | Beam-to-column connections |
| 200 × 200 mm | 12 – 16 mm | 19 mm (3/4″) | 120 – 250 mm | 4 – 6 | Heavy steel-to-concrete connections |
| 300 × 300 mm | 16 – 20 mm | 22 mm (7/8″) | 150 – 300 mm | 4 – 8 | Bridge and infrastructure embedments |
Material & Welding Specifications for Headed Shear Stud Assemblies
- To begin with, we use ASTM A36 or ASTM A572 Grade 50 steel plates as the standard embed plate material.
- Moreover, we produce our headed shear studs to ASTM A108 (Grades 1010 through 1020) and ISO 13918 for welded stud connectors.
- Additionally, we perform drawn arc stud welding per AWS D1.1 Clause 7 to ensure full fusion between the stud and the plate.
- Furthermore, our Type B headed studs meet the minimum tensile strength of 65,000 psi (450 MPa) and minimum yield strength of 51,000 psi (350 MPa), as required by AWS D1.1.
- For special orders, we supply 316L stainless steel studs for corrosion-resistant concrete embed plate assemblies.
- Finally, we offer OEM & ODM — we customize plate size, thickness, stud diameter, stud length, stud layout, and surface treatment according to your drawings.
AWS D1.1 Type B Headed Studs — Standard Requirements for Concrete Anchorage
In fact, AWS D1.1 defines Type B studs as headed, bent, or otherwise configured studs used as an essential component in composite beam design and concrete anchorage design[reference:0]. Furthermore, these studs are available in diameters from 1/2″ to 1″[reference:1].
To begin with, Type B headed studs differ from Type A general-purpose studs. Specifically, Type A studs have a minimum tensile strength of 61,000 psi, while Type B studs require a minimum of 65,000 psi[reference:2]. Moreover, Type B studs require a minimum elongation of 20% in 2 inches[reference:3].
Additionally, AWS D1.1 requires that the stud diameter must not exceed 3 times the base metal thickness of the embed plate. Consequently, we verify this ratio for every embed plate assembly before production.
Key AWS D1.1 Stud Welding Requirements We Comply With
- First, we weld studs using the drawn arc stud welding process with ceramic ferrules. This produces welds with full fusion that are stronger than the base metal or stud material alone[reference:4].
- Second, we visually inspect every weld for 360° flash formation, which indicates proper weld arc and full fusion around the stud base.
- Third, we conduct weld bend tests on production samples at the start of each production run, per AWS D1.1 requirements.
- Fourth, we remove ceramic arc shields after welding, as required by AWS D1.1 and state DOT specifications[reference:5].
- Finally, we can supply welding procedure specifications (WPS) and procedure qualification records (PQR) for each project upon request.
ACI 318 — Concrete Anchorage Design for Embedded Headed Studs
In addition, the design of concrete embed plate assemblies with headed studs follows ACI 318 Chapter 17 (Anchoring to Concrete). Furthermore, this code provides design requirements for anchors in concrete used to transmit structural loads by tension, shear, or a combination thereof[reference:6].
To begin with, ACI 318 addresses tension resistance, concrete breakout resistance, pullout resistance, and side-face blowout resistance for headed stud anchors[reference:7]. Meanwhile, it also covers shear resistance and the interaction of tensile and shear forces in concrete[reference:8].
Therefore, when you specify our embed plate assemblies, your engineer can design the connection using established ACI 318 provisions for cast-in headed anchors.
About Our Factory — Direct Manufacturer of Concrete Embed Plate Assemblies
In fact, Tarco Industry operates a modern manufacturing facility. Specifically, we dedicate it to the production of concrete embed plate assemblies and welded stud anchors.
Furthermore, we complete every step in our own factory. This includes steel plate cutting, stud welding, quality inspection, and packaging. Consequently, we do not outsource production. We do not act as a middleman.
In addition, we equip our factory with advanced CNC plate cutting machines and automated drawn arc stud welding equipment. As a result, we produce AWS D1.1-compliant embed plate assemblies with consistent weld quality and reliable stud positioning.

Why Choose Our Concrete Embed Plate Assemblies?
- For example, our embed plates offer Reliable Load Transfer. The headed studs transfer tension and shear forces between the steel connection and the concrete element.
- In addition, they feature Optimized Anchorage Design. The headed stud geometry provides mechanical interlock with concrete for high pull-out resistance.
- Moreover, they deliver Simplified Field Installation. The assembly installs into formwork before concrete placement. You simply weld the connecting steel member to the plate after stripping.
- Furthermore, they offer Easy Reinforcement Integration. We optimize stud length and layout so the studs avoid collision with reinforcement bars.
- As a result of their Precision Stud Welding, we ensure accurate stud positioning and consistent weld quality on every plate.
- Finally, we provide Direct Factory Support. Tarco Industry provides technical guidance, samples, and custom production.
How to Install Concrete Embed Plate Assemblies
- First, verify the assembly. Confirm that the embed plate dimensions, stud diameter, stud length, and stud layout match your design drawings.
- Then, fix the embed plate to the reinforcement. Wire-bind the embed plate with headed studs directly to the rebar cage or mounting bar so the plate does not move during concrete placement[reference:9].
- Next, fix the embed plate to the formwork. Alternatively, nail, screw, or wire-bind the plate directly to the formwork. Control close contact between the plate and formwork to prevent slurry leakage.
- After that, place and compact the concrete. Compact the concrete properly around the studs and plate. Avoid direct contact between the vibrator and the embed plate to prevent movement[reference:10].
- Finally, complete the structural connection. After concrete curing and formwork stripping, weld the connecting steel member to the exposed plate surface.
Applications & Industries for Concrete Embed Plate Assemblies
- For instance, in precast concrete construction, fabricators use our embed plates for wall panel-to-floor connections, beam corbels, and spandrel beams.
- Also, in composite steel-concrete construction, they transfer shear between steel beams and concrete slabs in high-rise buildings.
- In addition, for tilt-up concrete panels, they provide reliable anchorage points for lifting, bracing, and final structural connections.
- Furthermore, in bridge and infrastructure projects, they serve as durable anchorage systems for steel-to-concrete connections.
