Steel Embed Plate with Headed Shear Studs — AWS D1.1 Welded Anchor Assembly for Concrete Construction
First and foremost, Tarco Industry manufactures Steel Embed Plates with Headed Shear Studs in our own factory. In other words, we are not a trading company — we are the production source. As a result, we deliver factory-direct pricing, full weld traceability, and fast delivery for your concrete construction projects.
In addition, we produce these embedded anchor plate assemblies by welding headed shear studs (also known as headed stud anchors or shear connectors) to a steel plate using the drawn arc stud welding process in accordance with AWS D1.1 Structural Welding Code — Steel. Therefore, structural engineers and precast fabricators rely on them for transferring shear and tension loads between steel and concrete in composite construction.
Typically, the standard configuration consists of a square or rectangular steel plate with four headed shear studs welded to the back face in a symmetrical pattern. However, we also produce configurations with 2, 6, 8, or more studs, as well as custom stud layouts, plate dimensions, and stud diameters to match your specific design requirements.
Technical Specifications of Steel Embed Plate Anchor Assemblies
To begin with, we manufacture our steel embed plates with headed shear studs to meet AWS D1.1 requirements for stud welding, as well as AISC Specification Section I8.1 for steel headed stud anchor design. The table below summarizes the standard product range.
| Plate Size (mm) | Plate Thickness (mm) | Stud Diameter (mm) | Stud Length (mm) | Number of Studs | Typical Application |
|---|---|---|---|---|---|
| 100 × 100 | 8 – 10 | 13 / 16 | 80 – 120 | 4 | Precast wall panel connections |
| 150 × 150 | 10 – 12 | 16 / 19 | 100 – 150 | 4 | Beam-to-column connections |
| 200 × 200 | 12 – 16 | 19 / 22 | 120 – 200 | 4 – 6 | Heavy steel-to-concrete connections |
| 300 × 300 | 16 – 20 | 22 / 25 | 150 – 250 | 4 – 8 | Bridge and infrastructure embedments |
Material & Welding Specifications for Headed Stud Anchors
- 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 (process 783 per EN ISO 4063) with ceramic ferrules or shielding gas in accordance with EN ISO 14555.
- Furthermore, we comply with AWS D1.1 Table 7.1 Type B for headed stud connectors used in composite construction and concrete anchorage design.
- For special orders, we supply stainless steel (316/316L) 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 project drawings.
AWS D1.1 Stud Welding — Quality Requirements for Embed Plate Assemblies
In fact, the weld quality of headed studs to embed plates directly determines the load transfer capacity of the entire anchor assembly. Furthermore, we follow strict AWS D1.1 requirements to ensure every weld meets the specified strength and integrity standards.
Key AWS D1.1 Welding Requirements We Comply With
- First, we ensure the stud diameter does not exceed 3 times the base metal thickness of the embed plate, as required by AWS D1.1 for studs welded directly to base metal.
- Second, we perform drawn arc stud welding to produce full fusion between the stud base and the plate surface, creating a weld that is stronger than the base metal or stud material alone.
- Third, we visually inspect every weld for 360° flash formation, which indicates proper weld arc and full fusion around the stud base.
- Fourth, we conduct weld bend tests on production samples at the start of each production run, per AWS D1.1 requirements for stud welding procedure qualification.
- Finally, we can supply welding procedure specifications (WPS) and procedure qualification records (PQR) for each project upon request.
About Our Factory — Direct Manufacturer of Steel Embed Plates
In fact, Tarco Industry operates a modern manufacturing facility and we dedicate it to the production of steel embed plates with headed shear studs, anchorage assemblies, and custom welded steel components. Furthermore, we complete every step — from steel plate cutting and stud welding to quality inspection and packaging — in our own factory. Consequently, we do not outsource production, and we do not act as a middleman.
In addition, we equip our factory with advanced CNC plate cutting machines, automated drawn arc stud welding equipment, and strict quality inspection systems. As a result, we produce AWS D1.1-compliant embed plate assemblies with consistent weld quality, reliable stud positioning, and stable performance for B2B customers worldwide. Therefore, whether you need standard embed plates or custom configurations, Tarco Industry can produce them directly for you.

Why Choose Our Steel Embed Plates with Headed Shear Studs?
- For example, our embed plates offer Reliable Shear Transfer — the headed studs transfer shear forces between the steel connection and the concrete element, ensuring composite structural behavior.
- In addition, they feature Optimized Anchorage Design — the headed stud geometry provides mechanical interlock with concrete, delivering high pull-out resistance and ductile behavior under cyclic loading.
- Moreover, they deliver Simplified Field Installation — the embed plate assembly installs into formwork before concrete placement, and 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 and can be wire-bound directly to the rebar cage.
- As a result of their Precision Stud Welding, we ensure accurate stud positioning (perpendicularity within tolerance) and consistent weld quality on every plate.
- Finally, we provide Direct Factory Support — Tarco Industry provides technical guidance, samples, and custom production for your specific anchorage requirements.
How to Install Steel Embed Plates with Headed Shear Studs
- First, verify the assembly — confirm that the embed plate dimensions, stud diameter, stud length, and stud layout match your design drawings and project specification.
- 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. Ensure the plate surface is flush with the assumed concrete surface.
- 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 during compaction.
- Finally, complete the structural connection — after concrete curing and formwork stripping, weld the connecting steel member to the exposed plate surface to complete the structural connection.
Applications & Industries for Steel Embed Plate Anchor Assemblies
- For instance, in precast concrete construction, fabricators use our embed plates for wall panel-to-floor connections, beam corbels, spandrel beams, and dapped-end members.
- Also, in composite steel-concrete construction, they transfer shear between steel beams and concrete slabs in high-rise buildings and industrial facilities.
- 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 in bridge girders, pier caps, and abutments.
- Lastly, in nuclear power plants and industrial structures, they support the transfer of heavy loads from steel components and equipment to concrete structures.
