Introduction of U40 Steel Support Mining Support

40U type U-shaped steel bracket
Specifications and dimensions:
Width: Approximately 40 centimeters.
Thickness: typically 4-6 centimeters, providing excellent load-bearing capacity.
Height: The height is generally 40 centimeters.
Main features:
Extremely high load-bearing capacity: The 40U model is designed to withstand heavy loads or extreme construction conditions, suitable for large-scale projects.
Scope of application: Suitable for high-strength application scenarios such as large buildings, bridge construction, and heavy equipment support.
advantage:
Durable design, long service life, and stability in harsh environments.
Combining mature supporting technologies to ensure the safety of construction operations.
U Type Arch Steel for Mine Timbering is ideal for all support timbering applications where greater strength and superior corrosion resistance is required. Stainless Channel has a durable dull, mill finish that is widely used for all types of fabrication projects that are exposed to the elements - chemical, acidic, fresh water, and salt water environments.
The standard length for most size channel is 12'-14' random lengths, but lengths are available in some sizes up to 20' and longer. Finishes on channel can vary and include cold drawn, centerless ground, smooth turned, rough turned, turned ground and polished, and HRAP.
We will custom saw cut to length.
DEFARS or domestic material available in many sizes.
Polishing services are available.
