U300×64×4 mm Steel U Profile — S500

The 300x64x4mm steel U profile is a cold roll-formed plain channel: 300 mm web, 64 mm flanges and 4 mm thickness, 12.98 kg/m. Roll-formed to order in S500 steel, it is used as tracks, edge and closure channels and in general fabrication. This page shows the size in black (uncoated) steel S500, minimum yield 500 MPa; other materials can be selected above.

Made to Order — Roll Formed

Applications & Usage

U 300x64x4 is used as top and bottom tracks in light steel framing, edge and closure channels for panels, guides and machine guards. Black steel suits indoor structures and members that are painted or hot-dip galvanized after fabrication. Each size is roll-formed to order in lengths from 1 to 25 m. The minimum order is 5000 kg per size and material — add your sizes to a quote request and we confirm lead time and delivered price.

Weight and section properties are nominal values from the mill catalogue table. Values marked ≈ are calculated from the section centerline.

Indicative load span (single span, simply supported)

Allowable uniformly-distributed load (kN/m) limited by elastic bending about the strong axis (γ = 1.5 on yield, S500 (black steel)). Deflection is not checked and usually governs long spans. Indicative only — confirm with a project calculation.
