PEB frame type
Multi-span frame with 1 interior column
A gable frame with one column line under the ridge, giving two spans under one roof. Shorter rafter spans mean lighter steel for wide buildings.
Overview
What is a multi-span frame with 1 interior column?
The same gable roof as a clear-span frame, with one extra column line in the middle. The interior column shortens each rafter span, so rafters and exterior columns can be slimmer.
The roof stays a single gable with one ridge – no valley gutters – while the building can be much wider than a comparable clear-span frame.
Uses
When this frame fits
Wide buildings, one aisle
Warehouses where a central column line falls between two racking zones or along a main aisle.
Two production areas
Factories that naturally split into two halls under one roof.
Steel economy
When the extra column costs less than the heavier rafters of a clear span.
Cold and dry stores
Large storage buildings where the column line suits the room layout.
Design
What our engineers check
- 01
Column position
We place the column line to suit your racking, aisles and machines – it does not have to be exactly central.
- 02
Interior foundations
An extra row of footings is needed under the interior columns.
- 03
Crane runways
Each span can carry its own crane where needed.
- 04
Clear-span comparison
We show the steel weight of both options so you can decide.

FAQ
Questions Thai clients ask us
Does the interior column have to be in the middle?
No. It can be offset to suit your layout; the two spans are then designed separately.
Will the roof have a valley gutter?
No. A multi-span frame keeps one gable roof; valley gutters appear only on multi-gable frames.
Not sure which frame suits your building?
Send us your building size and use. Our engineers propose the frame type, steel weight and a CIF/DDP price for your site in Thailand.
