STRUCTURAL STEEL FABRICATION & INSTALLATION

BESPOKE STEEL BEAMS, FRAMES & SUPPORT STRUCTURES

Precision steelwork for complex construction projects.

Structural steel plays a critical role in modern construction, providing the strength and support needed for structural openings, extensions, renovations, balconies and specialist architectural projects. Accurate fabrication and careful installation are essential to ensure steelwork fits the building correctly and performs as intended.

360 GSS provides bespoke structural steel fabrication, supply and installation for homeowners, architects, builders, developers and main contractors. We manufacture steel beams, columns, posts and support structures to suit the dimensions, drawings and engineering requirements of each project.

From a single beam for a structural alteration to more complex steel frameworks for extensions, balconies and glazing installations, our team combines practical fabrication expertise with a coordinated approach to installation.

Where required, we can also work alongside our structural engineering and calculations service to help coordinate the engineering requirements with the steelwork being manufactured and installed.

This opening targets the core service while reinforcing a useful differentiator: the ability to coordinate engineering, fabrication and installation.

Structural Steel for Extensions, Openings & Bespoke Builds

Structural steel is often required when a building layout changes, a wider opening is introduced or a new structure needs reliable support. The correct steel components and connection details help transfer loads through the building in accordance with the project’s structural design.

360 GSS fabricates structural steelwork for a range of applications, including:

Rear and side extensions requiring steel beams and supporting columns.
Structural alterations involving load-bearing walls and enlarged openings.
New-build and renovation projects requiring bespoke steel frames.
Balcony projects incorporating structural support and glass guarding.
Architectural installations where steelwork must integrate with glazing or other materials.

For projects involving balconies and glazed guarding, our balcony and balustrade systems can be coordinated with the associated steelwork where appropriate.

Where a project needs a complete metal staircase rather than structural support beams alone, see our bespoke steel staircases.

Whether manufacturing an individual beam or a more complex steel package, our focus is on producing components that meet the project specification and can be installed accurately within the wider build.

our process

STEP 1

Request a Quote

Share your drawings, dimensions, photographs or project requirements so our team can review the proposed steelwork and prepare an initial quotation.

STEP 2

site survey & measure

Where required, we assess site dimensions, access, fixing conditions and installation requirements to confirm the details needed before fabrication begins.

STEP 3

DEPOSIT, Design & Engineering

Once the quotation is approved, a 50% deposit secures the order. Final fabrication details, dimensions and any outstanding engineering requirements are then confirmed before manufacture.

STEP 4

Structural Steel Fabrication

Steel components are fabricated to the agreed specification, with attention to dimensional accuracy, connection details and the required protective finish.

STEP 5

Install & completion

Where installation is included, our team positions and fits the steelwork with careful attention to alignment, connections, site safety and the finished result.

Structural Steel Designed for Long-Term Performance

Structural steelwork must do more than fit the opening or support the structure above. It needs to integrate correctly with the surrounding construction, accommodate the design requirements and provide dependable performance throughout its intended service life.

Our fabrication and installation process focuses on:

Accurate manufacture to the approved drawings and project specification.
Reliable connections and fitment in coordination with the supporting structure.
Integration with surrounding materials, including brickwork, timber, concrete, glass and aluminium.
Appropriate protective finishes selected for the installation environment.
Careful installation planning to account for site access, lifting and construction sequencing.
Coordination with engineering requirements where structural calculations or technical documentation are needed.

Where required, our structural engineering service can support the project with calculations and technical reports. The appropriate engineering, fabrication and approval requirements depend on the specific structure and application.
