Prefabricated Steel Structures – Engineered for Efficiency and Durability

Signal manufactures prefabricated steel structures, engineered for easy transport, fast on-site assembly, and long-term reliability. All components are produced in-house — from laser cutting and welding to finishing — under strict quality control and full compliance with EN 1090-1, EN 1090-2, and EN ISO 3834-2 standards.

Depending on the project scope, we either: Design and produce complete structures internally, or Fabricate and assemble structures based on client-supplied technical documentation and static calculations.

1. Bus Shelters and Urban Pavilions - Architecturally refined steel shelters and pavilions, developed and designed in-house by our engineering team. Used in parks, along bicycle trails, and in public rest areas, these prefabricated structures combine precise steel fabrication with modern design and quick installation.

2. Telecommunication Tower Bases and Frames - Prefabricated steel base frames and tower components for telecommunication installations - telecommunication antennas, radio units, microwave dishes, and associated transmission equipment fabricated according to external technical documentation. Our team ensures full conformity with EN 1090-2 production requirements and dimensional precision for effortless site assembly.

3. Gantry and Portal Sign Structures - Certified steel gantries and portal frames for road and traffic signage installations. These structures are designed and calculated by our traffic engineering team, ensuring full compliance with national road safety and static requirements. Each portal is fabricated in modular sections for easy transport and bolted assembly.

4. Custom Steel Frames and Equipment Supports - We also manufacture custom substructures, platforms, and equipment supports for industrial, civil, and infrastructure projects. Each structure is optimized for compact transport and fast on-site anchoring.

  • Prefabricated & anchored steel constructions
  • Fully manufactured in-house (design to assembly)
  • Compact transport – modular sections per project
  • EN 1090-1, EN ISO 3834-2 certified production
  • Durable welded steel frameworks

All production follows European standards: EN 1090-1 / EN 1090-2 – conformity of structural steel components and EN ISO 3834-2 – comprehensive welding quality requirements. Whether you require full in-house development or precise fabrication from existing technical documentation, our certified team ensures the same level of structural integrity, accuracy, and finish quality across every project.
