UniversalQReader vs Steel Sections

Universal QReader™ is a completely free smartphone/tablet App that allows you to read a Digital Seal SQCode®, a Digital Stamp dedicated to protecting documents that are typically used and controlled (even off-line) on the go. The Digital Seal SQCode®, is a QrCode code containing digitally signed data and therefore unfalsifiable. The data structure in the SQCode® Digital Seal is designed specifically for this kind of two-dimensional code and is ready to adapt to different contexts and applications. Data can also be encrypted, when it is necessary to ensure their confidentiality; they are also always signed, with the same philosophy, the same encryption algorithms and the same secure signature equipment used in a qualified signature. This architecture allows -only when it is necessary- the application of a qualified signature in the format CAdES/PAdES: in this case, the certificate of signature must be assigned to a natural person.
 In more general cases of use, instead, unqualified certificates will be used, typically assigned to a legal entity; this approach allows to define "Digital Seal SQCode®" an Electronic Seal, oriented to what is indicated in Europe's Digital Agenda. The Universal QReader™ App checks the data signature and presents it in a layout suitable for viewing on a mobile device. From the Universal QReader™ App you can then reconstruct the original document in PDF format so you can eventually share it in this form.

Steel Sections is a practical and fast-to-use tool designed to assist in the structural design of steelwork. The application, conceived and developed by Fondazione Promozione Acciaio and tested by leading executive design firms, architectural practices, and structural engineers, features a comprehensive database of over 9,000 steel profiles: IPE, IPN; HE, HD, HL, HLZ, HP; T-sections; UPN, UPE, U channels; equal and unequal leg angles; hot-finished and cold-formed circular, square, and rectangular hollow sections; plates; sheet piling; cold-formed steel (CFS) sections and sandwich panels. Key Features and Functionality: • Commercial Availability: Real-time data on profile availability, procurement lead times, and minimum order quantities. • Profile Search & Geometric Data: Quick and advanced search via category-specific filters. • Beam Verification: Calculation of stresses and deflections for single-span beams, including Ultimate Limit State (ULS) resistance checks and Serviceability Limit State (SLS) deformation checks. Calculations are adaptable based on boundary conditions, span length, loading types, profile arrangement, and steel grade. • Plate Verification: Thickness-based assessment. • Mass and Surface Area: Calculation per unit length. • Critical Load: Evaluation of the buckling load for members. • Design Resistance: Calculation of cross-sectional design strength. • Structural Analysis: Calculation of internal forces and deflections for both statically determinate and indeterminate beams. • User Customization: A "Favorites" section to save up to 50 profiles and a "Compare" function to evaluate different profile characteristics side-by-side. Future updates will integrate additional products and advanced functionalities.
