SM400 Structural Steel Channel

SM400 c channel is a structural steel commonly used in construction and engineering applications. It belongs to the Japanese Industrial Standard (JIS) series and is particularly suitable for heavy structures that require excellent mechanical properties.

There are three sub-grades under SM400 c section steel:

SM400A channel steel: basic grade with standard mechanical properties.

SM400B channel c steel: better toughness at lower temperatures.

SM400C c channel steel: enhanced toughness and stricter chemical composition control.

Common sizes of SM400 structural channel steel include: 50x37x4.5 mm; 63x40x4.8 mm; 80x48x5.0 mm; 100x63x6.0 mm, etc. GNEE can also provide larger sizes according to customer needs.

Advantages of SM400 Channel Beam: High strength-to-weight ratio; Excellent toughness, especially in Class B and C roadbeds; Good machinability and weldability; Suitable for applications where high strength and reliability are critical.

Surface treatments of SM400 Channels manufactured by GNEE can be customized to meet customer requirements:
Hot-rolled surface treatment (as is): Suitable for general use.
Galvanized coating: Provides enhanced corrosion protection.
Painted or powder coated surface treatment: For aesthetic purposes or additional protection.
