Structural Steel Connection Design Services
Steel connection calculations by Restoric® – Eurocode-compliant, buildable designs with full reports and 3D integration for structural steel projects.What is Steel Connection Design? – Critical Engineering for Structural Integrity
Steel connection design is the engineering process of determining how individual steel members—such as beams, columns, and braces—are joined together in a structure. These connections are fundamental to the strength, stability, and safety of any steel-framed building or architectural feature. At Restoric®, we design a wide range of connection types including bolted, welded, and hybrid joints, each tailored to suit specific load conditions, geometry, and construction methods. Properly engineered connections ensure that forces are safely transferred through the structure, while also allowing for practical assembly and installation on site.
Our connection designs are fully modelled in 3D and integrated into the broader detailing workflow. They are calculated using differing Software such as Advance Steel, Robot or calculated manually. We account for factors like shear, moment resistance, axial loading, and deflection, while also optimising for ease of fabrication and compliance with relevant standards such as Eurocode 3. Whether detailing simple shear connections or complex moment frames, Restoric® ensures every connection is not only structurally sound but also efficient to manufacture and erect—minimising site delays and reducing fabrication cost.
How We Design Steel Connections – From 3D Modelling to Structural Precision
At Restoric®, our connection design process starts with building a precise 3D wireframe model of the structural steel framework. This digital model allows us to visualise the spatial layout, identify clash risks, and coordinate all steel members before detailing begins. From primary beams and columns to secondary framing elements, this modelling phase sets the foundation for accurate and buildable steel-to-steel connections. It also ensures our connection designs integrate seamlessly with architectural constraints and site-specific conditions.
Once the structural layout is modelled, we design each connection based on load requirements, spatial allowances, and structural standards such as Eurocode 3. This includes both bolted and welded joints, as well as post-installed anchoring systems such as Hilti anchor connections. We also provide a comprehensive connection report for all designed joints, which includes calculations, connection types, bolt sizes, weld details, and fixing methods—ideal for structural engineer approval, fabrication documentation, or site verification. With Restoric®, you receive not only detailed connection drawings, but fully justified engineering support for every fix.

In accordance with Eurocode 3 (EN 1993), structural steel connections are critical to ensuring the safe transfer of loads between steel members. Common connection types include fin plate connections, end plate connections, toe plate connections, splices, and cleat angles. Fin plate connections are simple shear connections often used in beam-to-beam or beam-to-column scenarios, comprising a vertical plate welded to a support and bolted to the adjoining member. End plate connections—available as flush or extended—offer a stiffer alternative, enabling both shear and moment resistance by welding a plate to the end of a beam and bolting it to another member. Toe plate connections, often used at beam-to-column base junctions, involve a plate fixed at the “toe” of a member, typically for bracing or stabilising functions. These are particularly useful where space is limited or eccentric loading is present.
Splice connections enable the joining of steel members end-to-end, commonly used in beams and columns for ease of transportation and erection. Depending on project requirements, these can be executed with bolted or welded methods, allowing for both structural continuity and constructability. At Restoric, our steel detailing and connection design services are fully aligned with Eurocode 3 standards, ensuring precision, compliance, and efficiency. From standard connections to bespoke solutions like toe plates and complex moment joints, Restoric supports engineers and fabricators with high-quality detailing tailored to structural performance and cost-effectiveness.
Why Connection Detail Drawings Are Essential – Precision Engineering by Restoric®
Producing detailed connection drawings for each individual steel connection is a vital step in ensuring compliance with structural codes and constructability on-site. These drawings visually communicate the exact arrangement and dimensions of elements such as bolt spacing, edge distances, plate thicknesses, and weld specifications. By explicitly showing these detailing requirements, connection drawings verify that critical factors—like edge distances to prevent material failure, correct bolt pitch for load transfer, and spacing for tolerances—have been carefully considered. This level of clarity helps eliminate ambiguities during fabrication and installation, reducing costly rework and site delays.
At Restoric®, our steel detailing and connection design service prioritises the production of accurate, code-compliant connection drawings for every joint. These include precise dimensions, bolt layouts, weld types, and tool accessibility zones to ensure not only structural integrity but also ease of fabrication and erection. By addressing practical detailing aspects—such as wrench clearance, hole alignment, and material tolerances—Restoric® ensures that all connections are both buildable and structurally sound. Our expert team adheres strictly to Eurocode 3 requirements while optimising each connection for efficiency, safety, and fabrication cost—making Restoric® the trusted partner in steel detailing and connection design.
Electrical Schematic Drawings
Electrical schematic drawings are detailed, standardised diagrams that visually represent the electrical connections, components, and functions within a system. Unlike wiring diagrams, which focus on physical layout, schematics emphasize the logic and relationships between components, using internationally recognized symbols to depict elements such as switches, relays, circuit breakers, and power sources.
At Restoric® Design, we specialise in producing high-precision electrical schematics tailored to each client’s specifications. Using industry-standard CAD tools and adhering to relevant standards such as IEC and IEEE, our team transforms technical requirements and system data into clear, accurate drawings. These schematics support safe installation, efficient maintenance, and regulatory compliance across a wide range of engineering and infrastructure projects.
