Canale in acciaio zincato a caldo – Canale a U Q235B

QIDAMT · GALVANIZED CHANNEL

Q235B U-channel hot-dip galvanized for structural frames, arcarecci, supports and heavy racking.

Hot-dip galvanized channel steel is Q235B U-section channel immersed in a molten zinc bath. The thick zinc coating protects the flanges, web and inner corner against corrosion, giving excellent durability in humid, coastal and industrial atmospheres. It is widely used where a strong, corrosion-resistant structural section is required.

Vantaggi principali

Heavy-Duty Coating

Zinc protects all surfaces, dentro e fuori.

High Load Capacity

U-section resists bending and torsion.

Resistente alla corrosione

Ideal for coastal and humid climates.

Saldabile & Boltable

Easy to join with all common methods.
