What Makes Steel Portal Frames So Effective?

Steel portal frames are known for their ability to span large areas without the need for intermediate supports. This allows for more open floor plans and makes the structure more efficient to build and maintain.

Network Steel’s structural steel portal frames are expertly Crafted for Modern Construction. They come in various profiles, including RHS, SHS, U-Beam, and PFC. Smaller portal frames can be fully shop welded for simple installation, while larger frames often use bolted connections for easy transport.

It’s all about flexibility – the right frame for the right application.
