PEB frame type
Multi-span frame with 2 interior columns
Two interior column lines give three spans under one gable roof – a common choice for large warehouses and factories.
Overview
What is a multi-span frame with 2 interior columns?
A gable frame divided into three spans by two interior column lines. Each rafter span is shorter, so the frame stays light even when the building is very wide.
The spans do not need to be equal: a wider central span can keep a main aisle or loading zone free, with narrower side spans for storage or offices.
Uses

Wide buildings where steel weight drives the price.
Wide central aisle
A larger middle span keeps the main circulation clear.

What our engineers check

- 02
Column grid and racking
Column lines aligned with the racking module to avoid lost pallet positions.

Foundations
Two extra rows of footings under the interior columns.
- 04
Roof drainage
One gable roof, so water still drains to the two side gutters.

FAQ
Questions Thai clients ask us
Can the three spans be different widths?
Yes. Each span is designed for its own width and loads.
When should I choose many interior columns instead?
When the building is even wider and more column lines still suit the layout. We compare the options for your size.
Not sure which frame suits your building?
