U-Shapped Carbon Steel Strut Channel (3)

Core Manufacturing & Material Difference

C Channel (Hot Rolled Channel Steel)

Production: Hot rolling process, wall thickness ≥5mm

Material: Q235B / Q345B carbon steel, high bearing capacity

Feature: No curled lip, solid thick wall, good welding performance

C Purlin (Cold Formed Galvanized C Purlin)

Production: Cold bending galvanized strip steel, thickness 1.5–4mm

Material: S275GD galvanized steel, anti-corrosion for coastal projects

Feature: Pre-punched standard holes, curled edge for stronger torsion, lightweight

Load Capacity & Application Scenarios

When to choose C Channel

1.Main load-bearing frame, multi-story workshop support, bridge brackets, heavy equipment base

2.Projects with large vertical & dynamic load, require welding connection

When to choose C Purlin

1.Warehouse roof purlin, wall secondary support, solar bracket, temporary shed, billboard frame

2.Light steel building, fast assembly project, save freight & labor cost
 
Key cost advantage: C purlin is 30%-50% lighter than same-spec C channel, cut your ocean freight greatly; pre-drilled holes save 30% installation time without welding.
