Product data
A multi-storey building framework is the steel skeleton that lets you build upward quickly, safely and cost-effectively. Engineered around a repeating column grid, our steel frames deliver the strength of traditional construction with a fraction of the on-site time, making them an ideal choice for offices, apartments, hotels and industrial buildings that need multiple floors.
Every frame is designed, detailed and fabricated as one coordinated system – columns, beams, floor decks, bracing and connections all produced to fit together precisely. On site, crews simply bolt the members into place, floor by floor, with no wet-trade delays and no wait for concrete to cure. The result is a building that reaches its final height faster and starts earning earlier.

Multi-Storey Frame System Breakdown
A multi-storey steel frame is more than a stack of columns – it is a coordinated system of load paths:
Columns & Beams – H-section members form the vertical and horizontal grid.
Floor Systems – steel deck with concrete topping or composite slabs carry live loads.
Lateral Systems – braces, moment connections or core walls resist wind and seismic forces.
Connections – bolted or welded joints engineered for strength and ease of erection.
Composite Action – steel and concrete working together increases stiffness and span.

Why Choose Steel for Your Multi-Storey Building
For buildings of several storeys, steel framing changes the economics of construction. Because members are fabricated in the factory while site foundations are being prepared, the two critical paths run in parallel – typically cutting months off the overall schedule compared with cast-in-place concrete. A lighter frame also means smaller foundations, which matters on urban sites where soil conditions and basement work add cost.
Structurally, steel offers the highest strength-to-weight ratio of common building materials. That allows longer column-free spans for flexible floor planning, and it keeps the dead load low so seismic forces, which depend on mass, are reduced. With engineered bracing or moment frames, multi-storey steel buildings are designed to perform predictably in earthquakes, giving owners and occupants the safety they expect.
As an EPC supplier, Derun coordinates the entire delivery – design to your loads and codes, precision fabrication, documented inspection, international packaging and erection guidance. One team carries the responsibility from first drawing to final bolt, which keeps quality and schedule under control.
Typical Multi-Storey Configurations & Layout Options
Most multi-storey projects follow configurations we adapt to your site, use and budget:
Rectangular Grid – the most economical layout for offices and residential blocks, with regular bay spacing.
Long-Span Office Floor – wider bays for open-plan offices with fewer columns in the workspace.
Mixed-Use Tower – parking levels below and office or residential levels above in one frame.
Mezzanine-Enabled Industrial – factory floors with steel mezzanine levels for offices or storage.
Core & Perimeter Frame – a service core of stairs and lifts with perimeter columns for tall buildings.

Design & Engineering Process
Every multi-storey building starts with your requirements, not a template. Our engineers take your architectural drawings, storey plan or simple description and confirm the key parameters – number of storeys, bay spacing, floor loads, seismic zone and the local design codes that apply. That confirmation becomes the basis of the structural design, so the frame is right for your building from the very beginning.
The design then moves into detailed engineering: member sizing, floor system selection, connection design, lateral bracing and material schedules, all produced as clear workshop drawings. Because design and fabrication live in the same organization, every detail is checked against our production capability – cutting, welding and coating details are resolved before steel is ordered, not discovered on site.
Finally, production begins: steel is cut, drilled and welded on our intelligent fabrication lines, shot-blasted and coated, then inspected against the drawings. The result is a frame that arrives on site as precise, labeled members, ready to be erected floor by floor exactly as designed.
Performance, Durability & Maintenance
A steel multi-storey frame is engineered for decades of service with low, predictable maintenance. Fire-resistant coatings protect the structure where required, corrosion protection matches the local environment, and the dry, precision frame keeps walls and floors stable over time.
Expected Service Life – engineered for long-term use with proper maintenance.
Corrosion Control – coating and galvanizing systems matched to your environment.
Stable Structure – steel's dimensional stability keeps floors level and façades true.
Adaptable Space – partitions and services reconfigure without structural work.
Sustainable Material – steel is recyclable and fabrication minimizes site waste.
Understanding Your Cost & Quotation
Every multi-storey building is quoted individually because every project is different. Your quotation is built from the parameters that actually drive cost, so you can compare options and adjust the design to fit your budget.
Steel Quantity – the weight of columns, beams, floor systems and bracing.
Storeys & Floor Area – total levels and footprint set the scale of the frame.
Floor System – steel deck with concrete topping or composite options.
Fire & Seismic Provisions – protection systems required by local codes.
Façade & Finishes – cladding, glazing and architectural systems.
Shipping & Installation Scope – freight, packing and erection services.
Send your storeys, area and requirements, and our engineers will respond with an itemized quotation as soon as your requirements are confirmed.

Installation Services & On-Site Support
How your multi-storey frame gets erected is your choice, and we offer three levels of support. The most common is guidance-only: our erection drawings and step-by-step instructions travel with the steel, and your local crew bolts the frame together under our remote support. For teams with less experience, we can provide a supervisor who leads the erection on site and trains your workers floor by floor.
For clients who prefer a complete package, our installation team can manage the full erection. Either way, the process is planned in advance: foundations are prepared to our drawings, members are delivered in erection order, and each level is bolted and braced according to the sequence that keeps the structure stable at every stage.
Quality and safety are built into the process. We provide tightening specifications, inspection checklists and safety guidance, and every shipment is documented so site teams can verify each member against the drawings. Whatever level of support you choose, the goal is the same: a frame erected correctly, safely and on schedule.
Guidance-Only – drawings, instructions and remote technical support.
Supervision – an experienced supervisor leads and trains your crew.
Full Installation – our team erects the complete frame.
After-Sales – spare parts, maintenance guidance and warranty support.
