Building Steel Structure

Steel Building Structures Engineered Around Load Paths and Use.

Primary and secondary steel systems are developed around the building use, span, height, floor levels, local loads and project interfaces—then factory-fabricated, marked and prepared for coordinated international delivery.

Building Applications

Start with the Building, Then Select the Structural Logic.

A useful structural proposal begins with occupancy, circulation, equipment and envelope interfaces. The frame is then selected to create the required space while keeping fabrication, transport and erection practical.

01Industrial and Logistics Buildings

Efficient frames for production, storage, loading and future expansion.

02Commercial and Multi-Storey Frames

Floor-by-floor structures coordinated with circulation, facades and services.

03Large-Span Public Buildings

Truss or space-frame systems for halls, markets, sports and transport uses.

Structural Configurations

Choose a System That Fits the Span, Height and Building Use.

These are starting systems. Grid, member depth, connections, bracing and envelope supports are developed from the project brief and local design criteria.

Portal-frame steel building being erected for a single-storey industrial use

Best for efficient clear spans

Portal Frame Structure

An efficient single-storey system for industrial, storage and commercial buildings.

Five-storey steel frame with beams, columns and floor levels under construction

Best for vertical development

Multi-Storey Steel Frame

A regular floor grid for offices, mixed-use buildings and multi-level operations.

Best for column-free halls

Long-Span Roof Truss

Deep trusses create broad unobstructed areas for halls and public buildings.

Three-dimensional steel space-frame roof over a large public concourse

Best for broad roof footprints

Space-Frame Roof Structure

A three-dimensional roof system for broad or geometrically complex footprints.

Structural Supply Scope

Define Members, Connections and Building Interfaces Together.

The structural package is coordinated as one load path from primary members through bracing and connections. Envelope, floor, equipment and local works interfaces are identified before fabrication.

Core Structural Package

Primary columns, rafters, beams or roof trusses Secondary purlins, girts and stability bracing Connection plates, bolts and welded assemblies Base plates and identified foundation interfaces Fabrication drawings, member marks and packing lists

Project-Specific Options

Paint, galvanizing or specified corrosion protection Floor decking, stairs, platforms and mezzanines Crane, equipment and suspended-service supports Envelope rails, framed openings and facade interfaces Erection information and optional site guidance

Engineering Inputs

The Structural Scheme Follows Loads, Geometry and Interfaces.

Final member sizes and connection details depend on the building brief, applicable code, local site actions and coordinated loads from the envelope, floors and equipment.

Building use	Occupancy, operation, circulation and future change
Geometry	Length, width, height, floor levels, grid and roof form
Design actions	Dead, live, wind, snow, seismic and equipment loads
Interfaces	Foundations, floors, facade, services and specialist equipment
Design basis	Applicable code and authority requirements
Steel grade	Q235/Q355 or project-specified equivalent
Connections	Bolted and welded details developed for the system
Protection	Paint, galvanizing or fire protection by exposure and code

Structural Reference Configuration

A Long-Span Canopy Planned for Open Circulation and Wet-Weather Use.

This reference arrangement uses a repetitive long-span roof structure over an open-sided market and logistics space. The grid preserves circulation below while the roof geometry and drainage respond to a high-rainfall environment.

Project Delivery

From Structural Brief to Identified Steel Package.

Each stage confirms the load path and project interfaces before members are released for fabrication and shipment.

Define the Building Brief

Confirm use, geometry, loads, site criteria, interfaces and delivery scope.

Develop the Structural System

Coordinate the grid, members, stability system, connections and interfaces.

Fabricate and Inspect

Cut, assemble, weld, finish and verify components under factory control.

Mark, Pack and Coordinate

Bundle identified members with records and erection information for shipment.

Coordinated InterfacesStructure, envelope and operating requirements reviewed together

Defined Inspection PointsMaterials, welding, dimensions and finish checked by agreed scope

Installation-Led PackingMarked members, packing lists and erection information

Building Steel Structure FAQ

Questions That Define a Useful Structural Proposal.

Clear early inputs help select the system and avoid conflicts between structure, architecture, services and specialist equipment.

Which structural system is suitable for my building?+

The choice depends on use, clear span, height, number of floors, loads, architecture and erection conditions. Portal frames suit many single-storey buildings, while trusses, multi-storey frames or space frames may better fit other briefs.

What information is needed for an initial proposal?+

Start with the project country, building use, dimensions, grid or clear-span requirement, number of floors and available architectural drawings. Local loads, equipment and delivery requirements improve the first scope.

Can the structure be designed to a target market code?+

Yes, when the applicable code, load data and approval requirements are confirmed. The design basis and responsibility split should be stated before detailed engineering begins.

Can envelope and equipment interfaces be coordinated?+

Yes. Facade rails, framed openings, floor systems, crane loads, equipment supports and service penetrations can be included in the coordination scope when their requirements are available.

How are components prepared for site erection?+

Members are identified and bundled against packing records. Connection and erection information is prepared for the agreed scope, while the local contractor remains responsible for lifting, temporary stability and site safety.

Which works are normally completed locally?+

Foundations, slabs, underground services, permits, lifting operations and local installation are commonly handled at destination. The final quotation should state the exact supply and responsibility boundaries.
