Pre-engineered building or conventional steel? How to choose for a Thai project

Tapered built-up frames versus hot-rolled sections: steel weight, speed, flexibility and when each system makes sense for warehouses, factories and commercial buildings in Thailand.

Most single-storey industrial buildings in Thailand are built either as pre-engineered buildings (PEB) or with conventional structural steel made from standard hot-rolled sections. Both are steel; the difference is how the members are shaped.

How a PEB saves steel

In a PEB, columns and rafters are welded from plates into tapered I-sections. Software varies the depth along each member to follow the bending moment, so material is concentrated where forces are highest. Combined with lapped Z-purlins, this usually gives a lighter frame than one built from uniform rolled sections.

Where conventional steel wins

  • Multi-storey frames, heavy mezzanines and complex geometry
  • Heavy crane buildings where rolled or built-up runway beams dominate
  • Pipe racks, platforms and industrial structures with many connections

Speed and simplicity on site

Both systems arrive as bolted kits from our factory. PEB frames have fewer, larger pieces and standardised connections, which suits Thai erection crews and keeps crane time short.

Flexibility for the future

A PEB can be designed with removable end walls and frames ready for extension. Tell us about phase two at the start and the first phase will be ready for it.

Our approach

We do not sell one system – we design the one that is cheaper and better for your building, and often combine them: a PEB main hall with a conventional steel mezzanine and canopy, all from one model, one factory and one shipment.
