A steel elevator shaft is a prefabricated steel structure that houses elevator systems. Compared with concrete shafts, steel is faster to build, more flexible in design, and certified for safety and sustainability. This makes it the preferred solution for modern high-rise, residential, and commercial projects.
In this guide, you will learn the main components of a steel elevator shaft, the different types for various buildings, design options and section details, a clear comparison with concrete, and the top advantages including speed, cost savings, and adaptability.
At SteelPRO PEB, we are not just providing information—we are the Steel Structures / PEB Manufacturer & Producer behind these solutions. With ISO and CE certifications, EN 81-20 compliance, and factory-direct supply, we deliver certified elevator shafts, construction drawings, and wholesale pricing to clients worldwide.

Structural Components of Steel Elevator Shafts
A steel elevator shaft is made of several key components: the frame, protective skin, motion system, and optional add-ons. Each part is designed to ensure safety, durability, and compliance with international standards such as EN 81-20 and ISO certifications. Below we explain the main structural elements and their role in performance and long-term reliability.
1. Steel Frame Network
The steel frame is the load-bearing skeleton of the elevator shaft.
- Vertical Columns: High-strength steel columns (H-beam, box, or lattice type) spaced for load efficiency.
- Horizontal Beams: Connect columns and distribute floor loads.
- Diagonal Braces: Add lateral stability against wind and earthquakes.
- Connections: High-grade bolts or robotic welds for precise, certified joints.
This frame ensures stability and allows customized framing details and section layouts according to building codes.
2. Protective Skin
The protective layer ensures safety and resistance.
- Cladding Panels: Corrugated or flat steel sheets (galvanized or coated).
- Fireproofing: Mineral wool boards or spray coatings, certified to 2-hour fire rating (EN 81-20).
- Weather Protection: Corrosion-resistant finishing (zinc/aluminum-magnesium alloy).
This skin protects the structure from fire, moisture, and corrosion while meeting international safety certification requirements.
3. Motion Control System
This system keeps the elevator moving smoothly.
- Guide Rails: T-shaped rails installed with laser alignment.
- Damping Pads: Reduce noise and vibration.
- Hoist Beams: Integrated in the frame for lift operation (common query “hoist beam”).
Designed for precision and compliance with ISO 9001 quality control.
4. Smart Add-Ons (Optional)
Steel shafts can be upgraded with smart features:
- Utility Channels: Pre-installed for cables, sensors, and ventilation.
- Access Panels: Bolt-on doors for easy inspection and maintenance.
- IoT-ready Integration: Sensors for predictive maintenance and load monitoring.
These add-ons improve future adaptability and meet modern construction demands.Looking for detailed construction drawings or section details? SteelPRO PEB, as a certified PEB manufacturer, provides factory-direct elevator shaft components with full documentation.
Types of Steel Elevator Shafts: Choose the Right Fit
Steel elevator shafts are designed in three main types: freestanding, building-integrated, and modular. Each type meets different project needs, whether it’s a skyscraper, hospital, or fast-track housing. Choosing the right type depends on speed, cost, and building codes. Below we explain each type with applications and benefits.

Steel Structure Elevator Shaft Designs
Steel elevator shaft designs are usually divided into frame systems, truss systems, and hybrid systems. Each design affects load capacity, section details, installation speed, and noise resistance. Choosing the right design ensures safety and efficiency, and all designs can be customized by our factory to meet EN 81-20 and ISO 9001 standards.
1. Frame Systems
- Definition: Rectangular grids made of columns and beams, with welded or bolted moment connections.

Steel vs. Concrete Elevator Shafts: Key Considerations
When comparing steel elevator shafts vs concrete elevator shafts, the key factors are construction speed, long-term cost, design flexibility, sustainability, and structural performance. Below we break down each aspect with clear pros and cons.
Speed of Construction
- Steel: Prefabricated modules, no curing, installed in days. Example: a 20-story hotel completed shafts in 18 days.
- Concrete: Requires formwork, pouring, and 28-day curing. Weather delays common.
Winner: Steel – saves 50–70% of project time.
Long-Term Costs
- Steel: Higher material cost but lower labor and maintenance. No spalling or rebar corrosion.
- Concrete: Lower upfront cost but frequent repairs and waterproofing issues.
Winner: Steel – ~25% lower lifecycle cost.
Design Freedom
- Steel: Span up to 15m, curved or sloped shafts possible. Slim wall thickness frees floor space.
- Concrete: Limited to straight box shapes with thick walls.
Winner: Steel – more usable space and architectural freedom.
Sustainability
- Steel: 90% recyclable, prefab cuts waste by 80%. Contributes to LEED credits.
- Concrete: Cement responsible for ~8% global CO₂. Difficult to recycle.
Winner: Steel – greener and more sustainable.
Structural Limitations
- Concrete: Inherent fire and sound resistance.
- Steel: Modern coatings and EN 81-20 certified fireproofing close the gap. Acoustic panels add insulation.
Winner: Balanced – concrete still strong in fire resistance, but steel is safer and certified for modern use.
Manufacturer Perspective: SteelPRO PEB provides ISO/CE certified coatings and load-tested designs, ensuring compliance with international safety codes.
| Factor | Steel Shaft | Concrete Shaft |
| Speed | Installed in days, no curing | Long curing time, weather delays |
| Cost | Lower lifecycle cost | Higher maintenance |
| Design | Flexible, slim walls, custom shapes | Rigid, thick walls |
| Sustainability | 90% recyclable, low waste | High CO₂ footprint |
| Fire & Sound | Needs certified coating (EN 81-20, ISO) | Naturally resistant |
