O steel structure is a load-bearing framework composed of interconnected structural steel members—such as beams, columns, trusses, and braces—designed to support both vertical and lateral loads with high stiffness and reliability. Its high strength-to-weight ratio allows slimmer profiles and longer spans with less material than concrete or timber constructions.
Common Types of Steel Structures

Descriere |
Aplicații tipice |
|
Portal Frame |
Rigid connections of steel rafters and columns provide large, clear spans for industrial buildings. |
Warehouses, factories, aircraft hangars |
|
Multi-Storey Frame |
Vertical columns and horizontal beams supporting floors and walls allow flexible floor plans and vertical expansion. |
Offices, hospitals, hotels, residential highrises |
|
Truss |
Triangulated steel members forming lightweight, high-span assemblies are efficient under axial loads. |
Bridges, stadium roofs, and exhibition halls |
|
Space Frame |
A 3D lattice of steel tubes distributes loads in all directions, making it ideal for roofs that require minimal internal supports. |
Airport terminals, large atria, conference centers |
|
Light Gauge Steel Frame |
Cold-formed C or Z sections are used in low-rise buildings, supporting rapid, modular construction. |
Prefab homes, retail pods, and temporary structures |
|
Cable (Tensile) Structure |
High-strength steel cables anchored to towers form suspended decks or tensile roofs, achieving ultra-long spans with minimal depth. |
Suspension bridges, tensile canopies |
|
Pre-Engineered Buildings |
Factory-fabricated components delivered and bolted on site for fast assembly; optimized for cost and standardization. |
Distribution centers, workshops, and agricultural sheds |
Top 5 Reasons to Choose Steel Structure
- Eficiența costurilor
Lower material volume, fast fabrication, and simplified foundation reduce both initial and lifecycle costs. - Flexibilitatea proiectării
Enables column-free spans, complex geometries, and abundant natural light, allowing architects to bring their creative visions to life. - Speed of Construction
Precision fabricated in controlled environments and quickly erected onsite, shortening project schedules. - Durability & Safety
Resists extreme loads, seismic events, wind, and fire (with proper protection), outlasting many alternatives. - Sustenabilitate
100% recyclable steel supports circular economy goals; off-site fabrication minimizes waste and site impact.
Key Applications
High-Rise Buildings: Flexible floorplates and lightweight frames are ideal for skyscrapers.
Industrial Facilities: Clear-span factories and warehouses accelerate workflows.
Bridges & Infrastructure: Trusses and tensile elements enable record-breaking spans.
Sport & Event Venues: Space frames cover vast spectator areas with minimal supports.
Modular & Prefab Housing: Light-gauge frames deliver energy-efficient, rapid assembly homes.
Best Practices & Standards
Material Selection: Choose ASTM A36/A572 or EN S355 grades based on strength, corrosion, and fire requirements.
Connection Design: Bolted and welded joints must follow AISC (USA), EN 1993 (EU), or GB 50017 (China) guidelines.
Protective Coatings: Use galvanizing or intumescent paints in coastal or chemical environments.
Load & Stability Analysis: Conduct limitstate design per ASCE 7 or Eurocode 1 for accurate wind, seismic, and snow load combinations.
Controlul calității: Factory inspections, ultrasonic testing, and dimensional checks ensure consistency.
