Anchor plates – find manufacturers and suppliers

Anchor plates are load-bearing structural elements that usually consist of a steel plate to which anchor rods, ribs or stirrups are welded and serve as a connecting link between concrete structures and other components.

Their main task is to reliably transfer forces - tensile, compressive and shear forces - into the concrete and to ensure a secure, permanent connection between steel and concrete components.

Below you will find the functionality, design and material of anchor plates, as well as an overview of their use and areas of application and the special requirements placed on them:

How anchor plates work:

The functionality of an anchor plate is based on the load transfer between a connected component, e.g. a steel column, a façade or a machine structure and a concrete foundation or a concrete wall.

The steel plate is embedded in the concrete or concreted on, while the welded-on anchor rods are anchored in the concrete.

Under load, the anchor rods absorb the tensile forces and transfer them into the concrete, while the plate distributes the forces evenly.

The connection is made either by setting in concrete or by subsequent fastening, for example using dowels or mechanical systems.

It is important that the anchor plate is designed in such a way that no impermissible stresses arise in the concrete or in the anchors and that it meets the requirements for load-bearing capacity and durability.

Design and material of anchor plates:

Anchor plates are usually made of structural steel or stainless steel to ensure high load-bearing capacity and corrosion resistance.

Their dimensions depend on the transmitted forces, the concrete quality and the installation situation.

They are often dimensioned according to standards such as DIN EN 1992 (Eurocode 2).

For special requirements - such as increased corrosion protection, fire resistance or dynamic loads - special coatings or stainless steels are used.

Use and areas of application of anchor plates:

Anchor plates are indispensable in numerous construction and industrial sectors. Typical applications include

1. Building construction and civil engineering:
They are used as fixing points for columns, beams, bridge components, façade structures or railings.
In reinforced concrete construction, they are required for connecting steel structures to concrete foundations.

2. Industrial and mechanical engineering:
Anchor plates are used in the assembly of machines and systems to anchor machine frames or load-bearing structures securely in the concrete.

3. Facade and element construction:
In precast structures, anchor plates are used to connect precast concrete elements to each other or to attach façade elements.

4. Bridge construction and infrastructure projects:
Anchor plates are used to securely fasten steel structures to concrete substructures, for example in bridge bearings or when fastening railings.

Special requirements for anchor plates:

Several aspects are crucial in the planning and design of anchor plates:

• Load-bearing capacity: the plate must safely transfer the loads acting on it into the concrete.
• Anchoring length: The welded-on anchor rods require a sufficient embedment length in the concrete.
• Force transmission: Uniform stress distribution in concrete and steel.
• Corrosion protection: Coatings or stainless steel for exposed locations.
• Installation accuracy: Precise positioning is important to avoid fitting inaccuracies when installing the components to be connected.

Anchor plates are important connecting elements in modern construction and mechanical engineering. Their main function is the secure transmission of force between steel components and concrete. Due to their versatility, they can be found in almost all areas of construction and plant engineering. Professional design, execution and corrosion protection treatment are essential for a durable and safe construction.

Below is an overview of the most important points that should be considered when purchasing anchor plates:

When purchasing anchor plates, it is important to choose the right specifications for the application in question to ensure safety, load-bearing capacity, durability and cost-effectiveness. As anchor plates are used in load-bearing structures and safety-critical areas, technical precision and conformity to standards are essential.

• The selection of anchor plates depends largely on the type and magnitude of the forces that need to be transmitted - tensile, compression, shear and moment effects. Not only the maximum load must be taken into account, but also dynamic loads, vibrations or impact forces.
• The higher the load, the more solid and robust the plates need to be.
• Anchor plates are usually made of structural steel, e.g. S235, S355, or stainless steel. For outdoor applications or in aggressive environments such as chemical plants or coastal regions, corrosion-resistant materials or coatings such as hot-dip galvanizing or duplex coating are required. The choice of material influences both the load-bearing capacity and the service life.
• The surface treatment must be compatible with the building regulations and the planned service life.
• The size and thickness of the anchor plate must match the load-bearing capacity and the adjacent components. Important points:
• Thickness of the plate depending on the bending load
• Number, length and diameter of the welded anchor rods
• Hole pattern or welding surfaces for the components to be connected
• Incorrect dimensioning can lead to cracks in the concrete, deformation or premature failure.
• The type of anchoring - anchor rods set in concrete or subsequent fastening using dowels - must be matched to the construction method and the installation process.
• Anchors set in concrete are particularly strong and durable, but require precise positioning before concreting.
• Subsequent installation offers flexibility, but must guarantee high drilling and anchor quality.
• The anchoring length and the arrangement of the anchor rods are also decisive for load transfer.
• The anchor plates and their connections must comply with the applicable standards and regulations, e.g:
• Eurocode 2 and 3 for concrete and steel structures
• DIN EN ISO 17660 for welded connections
• CE marking for construction products
• For safety-relevant structures such as bridges, additional building authority approvals are required.
• The weld seams between the anchor plate and anchor rods are subject to high loads and must be professionally executed. Pay attention to:
• Welding certificates, e.g. in accordance with DIN EN ISO 3834.
• Test reports for non-destructive tests such as ultrasound or X-ray.
• Documented quality assurance
• Welding defects can significantly impair the load-bearing capacity.
• Precise dimensions are essential for problem-free assembly. Even slight deviations in hole patterns, panel thickness or anchor position can lead to installation problems or stresses. You should therefore ensure tight manufacturing tolerances and, if necessary, verifiable measurement reports.
• The anchor plate should be designed in such a way that it can be installed easily, quickly and safely on site. Aspects such as transport weight, lifting eyes and positioning aids can improve efficiency. In precast construction, precise integration into formwork is important.
• Rely on certified manufacturers who can provide complete documentation, e.g. material test certificates in accordance with EN 10204 and a certified quality management system, e.g. ISO 9001.
• In addition to the purchase price, transportation costs and installation times should also be taken into account. A higher unit price may be worthwhile if installation is faster, the service life is longer and maintenance is lower.

When purchasing anchor plates, the key factors are load-bearing capacity, material quality, manufacturing precision, corrosion protection and compliance with standards. Added to this are aspects such as ease of installation and quality assurance. Those who consider the structural requirements, installation conditions and long-term operating costs at an early stage will avoid problems later on and ensure a secure and durable connection.
