Multi-Story Steel Structure Office Buildings

KXD’s multi-story steel structure office buildings are engineered for corporate headquarters, administrative blocks, commercial complexes, and site office facilities that require fast construction, flexible layouts, and reliable structural performance.

Using pre-engineered structural steel framing, composite steel floor decking, and factory-fabricated components, these buildings help developers and contractors reduce on-site work while creating larger, more adaptable office interiors than many traditional concrete structures.

Each project can be customized according to footprint size, number of stories, floor-to-floor height, live load requirements, façade design, wind load, snow load, seismic conditions, stairwell layout, elevator shaft framing, and interior partition requirements.

Standard Specifications

The following parameters represent our standard manufacturing range. All specifications can be customized to meet your project requirements.

Technical Parameter Specification & Engineering Options
Primary Framing System Heavy-duty welded H-section steel or box columns (Q355B / Q235B grade, aligned with ASTM A572 / S355 standards)
Floor Decking System Galvanized composite steel floor decking sheets (integrated with cast-in-place concrete or precast concrete panels)
Secondary Framing Galvanized C/Z purlins, floor beams, secondary steel framing for stairwells, and elevator shafts
Facade & Exterior Walls • Glass Curtain Wall Systems (Double-glazed, low-E tempered glass for thermal and acoustic performance)

 

• PU/Rockwool Architectural Panels (With hidden-fix joints for a sleek cosmetic look)
Interior Partition Walls Lightweight drywall systems, acoustic gypsum boards, or integrated modular glass partitions
Surface Finish & Fireproofing • Anti-corrosive primer + polyurethane architectural topcoat

 

• Compatible with intumescent fireproof coatings to meet local fire ratings
Connection Technology Grade 10.9S high-strength structural bolt connections for primary frame joins
Live Load Capacity Standard office layouts (2.0 – 3.5 $kN/m^2$) or heavy filing/server room layouts (custom-engineered up to 5.0+ $kN/m^2$)

Frequently Asked Questions

  • Q

    What information is needed to design multi-story steel structure office buildings?

    A

    Please provide the building footprint, number of stories, floor-to-floor height, intended office layout, local wind speed, snow load, seismic activity level, façade preference, stair/elevator requirements, and any heavy-load areas such as filing rooms or server rooms.

  • Q

    How many stories can this steel office building system support?

    A

    The provided product system is optimized for low to mid-rise commercial office buildings, typically ranging from 2 to 6 stories. Final feasibility depends on structural calculation, local codes, site conditions, and the selected framing system.

  • Q

    How is the floor built in a multi-story steel office building?

    A

    A common method is galvanized composite steel floor decking installed on secondary floor beams, followed by reinforcement and concrete. Precast concrete panels can also be considered depending on project requirements.

  • Q

    Can the office building use glass curtain walls?

    A

    Yes. The structural steel framework can be engineered to support standard stick or unitized glass curtain walls, as well as aluminum composite panels or decorative sandwich panels for a modern office exterior.

  • Q

    Can the structure meet local fire safety requirements?

    A

    The steel frame can be designed for fireproofing treatments such as intumescent fireproof coatings or fire-rated gypsum board systems. The required protection method should be confirmed according to local fire-resistance rating codes.
