KLY Building Systems

Interior of a KLY steel building system — clear-span frame, insulated envelope and loading doors

Overview

Complete pre-engineered steel building systems

KLY delivers the complete building — structural system, building envelope, engineering and documentation, and project delivery. You buy a finished engineered building, not a list of steel parts.

The same system is configured for a battery storage building, a warehouse or a generator hall. What changes is the configuration — spans, heights, envelope, openings and access.

The system

Four parts of one building

Engineered, manufactured and delivered together as one building.

01

Structural System

The frame that carries the building — sized for its span, height and the actions of the site it stands on.

  • Primary steel frame
  • Secondary steel systems
  • Connections
02

Building Envelope

The weather-tight shell, specified to the building's use and thermal requirement.

  • Roof systems
  • Wall systems
  • Insulation
  • Weather protection
03

Engineering & Documentation

The engineering that makes the building work, issued with it — so it can be approved, built and maintained without going back to the drawing board.

  • Structural design
  • Drawings
  • Technical specifications
  • Compliance documentation
04

Project Delivery

Manufacture through to delivered building, sequenced to the site programme.

  • Manufacturing coordination
  • Quality documentation
  • Logistics

Configuration

Standard configuration ranges

Every building is configured to its site and its contents. These are the standard starting points:

ParameterStandard range
Clear span8 – 40 m single span; wider with internal columns
Eaves height3 – 12 m, set by equipment and access requirements
Bay spacing4.5 – 9 m, adjusted to openings and equipment positions
Roof pitch3° – 15°, matched to the roof system and climate
EnvelopeSingle-skin or insulated composite panel, factory-finished; insulation thickness to the thermal requirement
Frame protectionHot-dip galvanised to EN ISO 1461, painted, or duplex where the environment requires it
Design actionsEurocode wind, snow and imposed loads for the site location

Standard starting points, not limits — every building is configured to the site, the equipment inside it and the applicable design actions.

Delivery

How a building is delivered

01

Project Requirement

Site, building use, equipment and programme. Drawings welcome, not required.

02

System Configuration

Spans, heights, envelope, openings and access, set to the requirement.

03

Engineering

Design coordination and technical documentation, aligned to Eurocodes.

04

Manufacturing

Manufactured through qualified production partners to project specifications.

05

Delivery

Inspection release, packing and freight to the agreed destination.

06

Installation Support

Installation is completed by the customer's appointed contractor, supported by KLY drawings and documentation.

KLY configures, engineers, documents and delivers the building. Manufacture is through qualified production partners and installation is completed by your appointed contractor, with responsibilities agreed before manufacture.

Documentation

Engineering & quality documentation

Structural steelwork is manufactured under EN 1090 through qualified production partners, with the execution class set per project and certification held by the manufacturing partner. Every building is supplied with a project document pack:

  • Declaration of Performance (DoP)
  • CE / UKCA marking documentation
  • Material test certificates (EN 10204 3.1)
  • Welding procedure and welder qualification records
  • Inspection and dimensional check reports
  • Galvanising or coating certificates
  • General arrangement and structural drawings
  • Packing lists and delivery documentation

See engineering & documentation for what the engineering covers.

FAQ

Building system questions

A pre-engineered building system is a complete building engineered as one system — structural system, building envelope, engineering and documentation, and project delivery — configured to each project rather than designed from a blank sheet. The result is a shorter engineering programme, predictable manufacturing and a complete documentation pack.

Spans, eaves heights, bay spacing, roof pitch, envelope build-up, openings and finishes are all configured per project. The standard ranges published here are starting points; buildings outside them are assessed on the project requirements.

Every building is engineered before it is manufactured — design basis, structural calculations, general arrangements and connection details — and the engineering is issued with the building. Deliverables and design responsibility are agreed for each project before manufacture.

Through qualified production partners, selected around the project's technical requirements, programme and commercial priorities. Structural steelwork is manufactured under EN 1090, with the execution class set per project and certification held by the production partner.

KLY delivers the complete engineered building — structure, envelope, engineering and documentation — to site. Installation is completed by the customer's appointed contractor, working from KLY drawings and documentation, with the interfaces to the civils and installation teams set out before delivery.

A site location, the intended use, approximate footprint and any equipment the building has to house is enough to start. Drawings are welcome but not required — most projects begin with a requirement rather than a design.
