Ordinary surface (FA)
Pickling surface: The surface is allowed to have minor, local defects such as pitting, concave surfaces, scratches, etc. with a depth (or height) not exceeding half of the steel plate thickness tolerance, but the minimum allowable thickness of the steel plate and steel strip should be ensured.
Higher level surface (FB)
Pickling surface: The surface is allowed to have local defects that do not affect the formability, such as slight scratches, slight indentations, slight pitting, slight roller marks and color differences, etc.
Mainly used in construction, bridges, ships, vehicle structural parts, manufacturing various tools, cutting tools, molds and measuring tools, etc.
“Strut channel” refers to a common structural component used in construction and electrical installations. It is also known as “channel,” “channel strut,” “strut,” or “strut channel system.” The term often refers to a standardized structural system composed of metal channels shaped like the letter “C” or “U.”
Key features of strut channels include:
Material: They are typically made of metal, commonly steel or aluminum, offering strength and durability.
Shape: The channels are often in a “C” shape, allowing for easy attachment of various components and fixtures.
Perforations and Holes: The channel may have regularly spaced holes or perforations along its length. These holes facilitate easy attachment using bolts, nuts, or other fasteners.
Uses:
Support Structures: Strut channels are commonly used to create support structures for conduits, pipes, cable trays, and HVAC systems in commercial and industrial buildings.
Electrical Installations: They serve as a framework for mounting electrical panels, switches, outlets, and other electrical components.
Racks and Framework: Strut channels are often used to construct frameworks and racks in various applications.
Compatibility: They are designed to be compatible with a range of accessories and fittings, such as channel nuts, spring nuts, angle brackets, and beam clamps.
Adjustability: The perforations along the channel allow for easy adjustment and customization of the system to suit specific needs.
Standardization: Strut channels are often produced based on industry standards, such as those set by the Metal Framing Manufacturers Association (MFMA) or other regional standards.
Finishes: They may come with different finishes, such as galvanized, pre-galvanized, or painted, to provide corrosion resistance.
The versatility and ease of use make strut channels a popular choice for constructing support structures and frameworks in a variety of applications within the construction and electrical industries.
