Steel Building Manufacturing

ESB has a dedicated manufacturing facility focused on producing our own steel building system. This allows the principal building components to be manufactured and coordinated as one complete package.

The steel frame, brackets, cladding and flashings are all produced within the same facility, helping maintain consistency between the approved drawings, structural components and external envelope.

By controlling these connected stages, ESB can prepare each made-to-measure building around its agreed dimensions, openings, specification and intended use.

This footage shows the automated production equipment used to manufacture the cold-rolled steel sections that form the main structure of an ESB building.


The main structural and external components of an ESB building are manufactured together, helping the completed package correspond with the approved design and specification.

Steel Frame

Cold-rolled columns, rafters, purlins and side rails are produced to suit the building dimensions and structural design.

Brackets and Connections

Connection brackets and associated fabricated components are prepared for the fully bolted ESB building system.

Roof and Wall Cladding

Single-skin profiled cladding is manufactured to the required lengths, profile and agreed colour specification.

Flashings and Trims

Corners, ridges, eaves, openings and other junctions are finished with purpose-made flashings and trims.

Specialist components
Including: Doors, insulated panels, rooflights, bolts and fixings are sourced from established manufacturers and coordinated with the ESB building package.

Manufacture begins after the building specification and general arrangement drawings have been approved. The principal components can then be produced, identified and prepared as one coordinated package.

An ESB building is manufactured as a coordinated structural system rather than a collection of unrelated components. Each part has a defined position and purpose within the approved building design.

The system is often described as “giant Meccano” because the individually identified members can be cross-referenced with the construction drawings and interactive 3D model during erection.

  • Fully bolted steel-frame construction

  • Purpose-made brackets and connections

  • Rigid structural bracing rather than wire bracing

  • Individually identified structural members

  • Construction drawings supplied with the building

  • Interactive 3D model showing how the components connect

Keeping the principal components within one coordinated process helps the manufactured building correspond with the agreed design and construction information.

Approved Information

Manufacture follows the approved building configuration, drawings and agreed specification.

Made-to-Measure Production

Structural members, cladding and flashings are produced for the dimensions and openings of the individual building.

Identified Members

Structural components are marked so they can be cross-referenced with the construction drawings and 3D model.

Coordinated Packing

The completed components are organised and packed together ready for transport and erection.

Once manufacture is complete, the structural members, cladding, flashings and agreed accessories are organised for the individual project and prepared for loading.

ESB arranges transport to the confirmed delivery address. The customer normally provides suitable unloading plant and a competent operator unless an alternative arrangement has been agreed in advance.

Careful delivery planning helps ensure the vehicle can reach the site, the building can be unloaded safely and the components can be stored appropriately before erection begins.


Tell ESB your required dimensions, intended use, site postcode, openings and preferred cladding specification. We will help develop the right made-to-measure building package for your project.
