I Beams (S-Shapes)
I beams engineered for load bearing applications where a narrower flange profile is required. Hot rolled from certified steel and processed to tight dimensional tolerances, these beams are suited for framing, support structures, and general fabrication where consistent strength and predictable performance are essential.
Key Features
- Standard I beam (S) profile with tapered flange surfaces
- Hot rolled construction for consistent grain structure and strength
- Manufactured to ASTM A36 and A992 standards
- Straightness and camber controlled within AISC tolerances
- Mill finish, primed, or hot dip galvanized coating options
- Custom cutting, drilling, and length options for project specific orders
