Panelised Building Kit

When freight volume matters more than site labour, the building ships as flat panels and marked members — a numbered kit that a local crew erects from our drawings.

Product overview

What It Is and What It Does

A panelised kit is the same engineered building as a volumetric module, taken apart for the sea leg. Wall, floor and roof panels ship flat and the frame ships as marked members, so the container carries building rather than air.

The trade is straightforward: lower freight cost and a smaller crane requirement, in exchange for more assembly work at the destination. Where local labour is available and freight is expensive — which describes most long-haul projects — the kit wins.

The UMMO complex in El Salvador is the clearest example: over 3,000 m² of two-storey blocks on a light steel frame, delivered as a numbered kit and erected on site by a local crew working from our drawings and bolt schedules.

Key benefits

What You Get From It

Lowest freight per square metre

Flat panels and marked members fill a container far more efficiently than finished modules.

Smaller crane requirement

Panels are lighter than whole modules, which matters on sites with limited lifting plant.

Local labour does the assembly

Work and money stay in the destination economy, which is often a contract requirement.

Same engineering as a module build

The kit is engineered for your loads, not simplified for shipping.

Problems it solves

The Situations This Product Answers

Freight budgets on long hauls

Shipping finished volume across an ocean is the most expensive way to move a building.

Sites with light lifting plant

A kit can be built with plant that could never place a volumetric module.

Local content requirements

Contracts that require local labour are satisfied by the erection scope.

Buildings that must be extended later

A kit system extends cleanly by adding bays.

Who it is for

Materials

What It Is Made From

Frame

Light steel members, cut and drilled on CNC lines, galvanised or primed.

Wall and roof panels

Insulated panels specified for the destination climate.

Floors

Engineered floor build-up specified per project.

Fixings

Bolts and fixings supplied with the kit against the schedule.

Manufacturing process

How It Is Made

Engineering

Building engineered for your loads; erection sequence designed with it.

CNC cutting

Members cut and drilled so bolt holes match the erection drawings.

Welding and finishing

Frames robot welded and galvanised or primed.

Panel production

Panels cut to the frame module and finished.

Marking

Every member and panel marked to its position on the erection drawings.

Load

Packed to the container plan and photographed before sealing.

Quality control

Three-Stage Quality Control

  • Engineered to AS/NZS and EN (CE) where specified
  • Material certificates and load-test reports supplied per order

Customisation Options

  • Building layout, bay spacing and storey count
  • External facade finish and colour
  • Insulation specified for the destination climate
  • Openings, glazing and door schedule
  • Foundation interface detailing
  • Phased delivery across several shipments

Getting It Right on Site

Read the bolt and panel schedule before starting

It sets the sequence; working out of sequence is the most common cause of rework.

Check the kit against the schedule on arrival

Confirm completeness before the crew mobilises, not on the day they need a part.

Erect the frame square before panelling

Panels are cut to the frame module, so frame accuracy decides panel fit.

Use the engineering support

Our engineers stay reachable through assembly — a question answered in an hour is cheaper than a week of guessing.

Buyer questions

Panelised Building Kit FAQ

What buyers ask before placing an order for this product.

What exactly arrives in a panelised kit?

Marked steel members, wall, floor and roof panels, fixings, erection drawings and a bolt and panel schedule — everything the crew needs to build in sequence.

How much cheaper is a kit to ship than whole modules?

Flat panels fill a container far more efficiently than finished volume. The exact saving depends on the building, and is shown on your loading plan before you order.

Do we need specialist labour to erect it?

No. The UMMO complex in El Salvador was erected by a local crew working from our drawings and bolt schedules. Supervision is available for the first block.

Can we extend the building later?

Yes. Kit systems extend by adding bays, provided the original engineering allowed for it — tell us at the design stage if extension is planned.

Is the engineering the same as a module build?

Yes. The kit is engineered to your wind and seismic loads with stamped reports for your jurisdiction; only the delivery format differs.
