Physical properties of galvanized channel steel: The total heat transfer coefficient of metal depends on other factors besides the thermal conductivity of metal. In most cases, the heat dissipation coefficient of the film, the scale and the surface condition of the metal. Stainless steel keeps the surface clean, so it conducts heat better than other metals with higher thermal conductivity.
The galvanized channel steel is heated to 850 to 1250°C, and then subjected to a heat treatment of cooling at a cooling rate of 1°C/s or more. In this way, it can become a high-strength galvanized channel steel with a volume fraction of more than 12% martensite, high strength of more than 730MPa, corrosion resistance and bending performance, and excellent toughness of the welding heat-affected zone. Reuse of Mo, B, etc., can significantly improve the stamping performance of the welded part.
Hot and cold rolled steel channels are perfect for all types of industrial structural applications, including structural applications, general fabrication, manufacturing, maintenance, and repairs. Since it’s easy to cut, weld, form, and machine, ASTM A36 steel channel is the preferred choice for industry specialists worldwide.

According to customer's requirement
Cold Rolled Steel Channel
Also known as cold-rolled channel (CRC), cold-rolled u-channel is strong, resilient, and provides increased yield strength and hardness qualities that hot rolled steel does not possess.
Cold Rolled Steel Channel Applications
Cold rolled ASTM A1008 steel channel products are used for the following applications:
