ASTM 2mm Thickness HDG C Channel
Product Overview
ASTM 2mm Thickness HDG C Channel is a hot-dip galvanized steel channel used for structural framing, solar mounting systems, cable supports, equipment frames, and industrial applications. The 2mm wall thickness offers a good compromise between strength and weight, and the HDG zinc coating enhances corrosion resistance for outdoor applications.

Hot-Dip Galvanized Steel C Channel Manufacturing Process
1.Steel Coil Preparation – ASTM-grade steel coils are inspected and prepared for processing.
2.Slitting – Coils are slit to the required width according to the C channel dimensions.
3.Roll Forming – The steel strip is continuously roll-formed into the required C-shaped profile.
4.Cutting & Punching – Channels are cut to specified lengths, with slots or holes added when required.
5.Hot-Dip Galvanizing – The formed C channel is coated with molten zinc for corrosion protection.
6.Inspection – Dimensions, thickness, surface condition, zinc coating, and material certificates are checked.
7.Packing & Delivery – Finished C channels are bundled securely and prepared for container or bulk shipment.
Application
Solar Mounting Systems – Rails, supports, and PV structures.
Steel Framing – Wall, roof, and structural framing.
Cable Tray Supports – Supports for electrical and communication systems.
