The engineering and construction company Rauta has published a guide titled “Fastening Cantilevered Structures to Sandwich Panels,” intended for designers and specialists working with building envelopes.
According to the company’s website, the guide will be useful when calculating loads on Ruukki sandwich panel cladding caused by suspended elements. The guide contains recommendations on the level of utilization of the panels’ load-bearing capacity, requirements for calculating fasteners for suspended elements, as well as specifics for determining loads from vertically installed U- and Ω-profiles or cantilever supports for cable ladders.
The document also specifically addresses point loads from through-fasteners. This is important for industrial, warehouse, logistics, and commercial facilities where engineering components, cable trays, additional structures, cladding, or auxiliary equipment may be attached to facades or wall panels.
For the construction market, these guidelines are of practical importance, as sandwich panels are widely used in prefabricated buildings, industrial facilities, cold storage warehouses, agricultural infrastructure, and retail and logistics complexes. Errors in the design of fasteners can lead to improper load distribution, damage to the cladding, compromised airtightness, or reduced durability of the building envelope.
Rauta operates in the engineering and construction solutions sector and offers building design, the supply of frames, sandwich panels, ventilated facades, and prefabricated buildings, as well as structural installation, general contracting, client services, building commissioning, and maintenance.
The company positions itself as a provider of reliable construction solutions in Ukraine and European Union countries. Rauta uses certified European-manufactured products and is the exclusive supplier in Ukraine of commercial products from the Finnish Ruukki Group.
One of Rauta’s key areas of activity is Ruukki sandwich panels. According to the company, these panels are manufactured using Finnish technologies at Ruukki’s European plants and comply with the European standard EN 14509. The supply of panels is accompanied by consultations on selection, the design of building envelopes, technical solutions, components, panel layout on facades and roofs, as well as calculations of the structures’ load-bearing capacity.
Rauta also develops its own engineering solutions. These include a patented frameless building design using sandwich panels, a construction technology for multi-story buildings that uses sandwich panels as walls, solutions to improve building airtightness, and technologies for renovating structures using energy-efficient sandwich panels.
In 2024, the company received a patent from the Ukrainian National Office of Intellectual Property and Innovation for a technical solution for a frameless building made of sandwich panels. According to Rauta, this technology can be applied to single-family homes, cottage communities, cold storage rooms, refrigerated warehouses, and other single-story residential or commercial buildings.
In addition, Rauta is a member of relevant business and industry associations. The company is part of the Ukrainian Center for Steel Construction, the Finnish Business Group, the Finnish-Ukrainian association UkraineOffice, and the German-Ukrainian Chamber of Industry and Commerce (AHK Ukraine).
The release of the new guidelines indicates that the company is focusing not only on the supply of materials but also on providing engineering support for projects. For clients, this can reduce risks during the design and operation phases of buildings, and for the market, it can raise standards for working with sandwich panels and cantilevered structures.
