Carbon Steel Profiles

Carbon steel profiles are rolled structural sections such as H and I sections, channels, tees and hollow sections; they are purchased as standardized members, not as a fabricated building system delivery package.

Common grades

Grade + product

ASTM A36 Structural Steel Profiles

ASTM A36 structural steel profiles for general welded, bolted and riveted structural work; order the exact product form, section, dimensions and supplementary requirements.

Grade + product

ASTM A572 Grade 50 Structural Steel Profiles

ASTM A572 Grade 50 structural steel profiles for higher-strength structural work; thickness, section, toughness and fabrication requirements remain project-specific.

Specifications and dimensions

Section designation, nominal depth, flange width, web and flange thickness and mass per length
Standard mill length or fixed length, straightness, sweep, camber and twist
Rolled surface, blast-cleaned or primed condition and permitted end processing

Standards and supply condition

ASTM A6/A6M general requirements with the ordered structural grade specification
EN 10025-2 material requirements with section dimensional standards such as EN 10034 where applicable

Manufacturing and processing

Bloom or beam blank is reheated and passed through section mills to form the web and flanges.
Controlled cooling, straightening, cutting, marking and optional shot blasting or primer complete supply.

Typical applications

Building and industrial frames
Bridges, platforms and transport structures
Equipment supports, pipe racks and crane structures

Quality and acceptance controls

Match heat or coil identity, grade, product specification and delivery condition to the material certificate.
Check dimensions, tolerances, straightness or flatness, surface condition, marking and permitted repair.
Agree mechanical, impact, pressure, NDE or coating tests and third-party witness points before production.

Include in your RFQ

Grade and governing product specification
Hot-rolled or cold-rolled route and delivery condition
Dimensions, tolerances, length or coil geometry and quantity
Surface, edge or end preparation and coating requirement
Mechanical, impact, pressure, NDE and inspection-document requirements
Marking, traceability, packing, destination and delivery term

Selection limits

Section availability and dimensional series vary by regional standard and mill; nominally similar shapes may not share properties.
Member selection and connection design remain the responsibility of the project structural engineer.
