ASTM A36 C Channel Steel for Construction Roads Bridges Manufacturing
A36 hot rolled steel C channels, also known as "American Standard Channels," are highly versatile and suitable for various processing techniques. These channels have a rough, blue-grey surface finish. A36 material is a durable and long-lasting type of mild steel with low carbon content. Hot rolled C channels are classified as "structural shapes" because at least one dimension, excluding length, exceeds 3 inches. What sets them apart from "MC" channels is the approximately 16-2/3% slope on the inside flange surface. These channels find common applications in structural support, trailers, and architectural uses. The ASTM A36 / A36M-08 standard specification governs the use of carbon structural steel.

Application
Channel steel is widely used in construction, roads, bridges, manufacturing, photovoltaic and other fields.
The main uses include:
1. Manufacturing frames and columns - Channel steel is characterized by being solid and durable and can withstand heavy and other types of unstable loads. Construction workers usually use channel steel to build building frames and columns.
2. Manufacturing light steel structure - light steel structure steel skeleton is composed of channel steel, I steel, square steel, etc., as a new generation of steel structure system, its construction speed, low cost, light weight, long life, has been widely used.
3. Manufacturing doors and Windows - Channel steel can be made into different shapes and sizes of doors and Windows parts, widely used in industrial, commercial and residential buildings.
4. Making machine parts - Channel steel is usually used to make important parts of machines and equipment, such as hydraulic devices and the skeleton of large machines.
FAQ
1.What is the C-channel used for?
C channels are one of the more common types of metal channels and are widely used in construction as building, wall, roof, and ceiling supports. The term C channel encompasses a wide variety of channel types, dimensions, and sizes since sheet metal can be roll formed to fit any specific requirements.
2. What do you need to consider when choosing C channel steel?
Tensile strength, dimensional accuracy, surface quality.
3. What are the specifications of C channel steel?
Waist height (h), leg width (b), waist thickness (d), etc. For example, the Japanese standard channel steel specifications are jisg3192-2016 and jisg3101-2015, and the size is expressed in ways such as h*b* d.150 *75*6.5, indicating that the waist height is 150mm, the waist width is 75mm, and the waist thickness is 6.5mm.
