Hot Rolled Technique ASTM 201 304 304L 316 409 Stainless Steel U C Shaped Channel For Building Structure

classification

Channel is divided into ordinary channel and light channel. The specification of hot-rolled ordinary channel steel is 5-40#. The specification of hot-rolled flexible channel steel supplied by agreement of both parties is 6.5-30#. Channel steel is mainly used in building structures, vehicle manufacturing, other industrial structures and fixed cabinets, etc. Channel steel is often used with I-steel.

Channel steel can be divided into four kinds according to shape: cold-formed equilateral channel steel, cold-formed unequal channel steel, cold-formed inner coiling channel steel, cold-formed outer coiling

According to the theory of steel structure, it should be the channel steel wing plate force, that is, the channel steel should be standing, not lying down.

2
Serial number

① Use international symbols of chemical elements and national symbols to represent the chemical composition, use Arabic letters to represent the content of the composition:

For example: China, Russia 12CrNi3A

② With fixed number of numbers to represent the steel series or numbers; Such as: The United States, Japan, 300, 400, 200;

③ Use Latin letters and order to form serial numbers

3
Cosmetic requirements

The allowable deviation of channel steel surface quality and geometric shape is specified in the standard. It is generally required that the surface shall not have harmful defects and significant torsion, and the allowable value of channel steel wave bend (sickle bend) and the value and allowable value of relevant parameters (H, B, D, T, etc.) of channel steel surface shape in various specifications. Channel steel geometry is incorrect main performance is: Angle, leg spread and leg and so on.

U section steel is a kind of high quality economic section steel with double mechanical properties made from l section steel.
U-shaped steel has the characteristics of low cost, high precision, low construction cost of steel structure and light assembly.
Adopt advanced machinery and equipment to process, cut smooth, save welding work.
The commonly used specifications have sufficient stock, large quantity of stock and fast delivery.
