Steel Portal Frame

Product Overview

The Steel Portal Frame is a widely used structural system consisting of rigidly connected steel columns and rafters, forming a stable frame capable of resisting vertical and horizontal loads. It is one of the most economical and efficient solutions for low-rise, large-span steel buildings.

Steel portal frames are commonly applied in:
Industrial workshops and factories
Warehouses and logistics centers
Agricultural buildings
Aircraft hangars
Commercial and storage facilities
Pre-engineered steel buildings (PEB)
