# Flat Steel

**Material**

A36

A36 steel flats are for general structural use with a 36 KSI minimum yield strength. Material is certified to ASTM A36 and ASME SA36.

**Uses**

Actually Flat bar products are widely and professionally applied on manufacturing industry of steel structure, mechanical manufacture, automobile industry, Mine machinery and hoisting machinery, etc. According to its hot rolled and cold drawn process, we may consider its uses such as

Hot rolled flat bar steel

1. It may use for construction members, staircases and fences, etc. The hot rolled flat bar features smoother surface, good weldability, stronger load capacity, etc, so it is met to requirement of construction members, fences and staircases products.

2. Hot rolled flat steel can be used as the billet of welded steel and the slab of pack-rolled sheet.

3. The hot rolled flat steel could finish and produce about hoop iron because of its rectangle shape, good flexibility, variety of specification of width and length.

Cold rolled flat bar steel

The cold rolled or cold drawn flat bar meets to steel property and good surface evenness, so it is well used in machine tool building, hydroelectric facility manufacturing, fabrication of wood-working machine, home appliances, office equipment, instrument and meters, construction machinery, standard parts, steel furniture and crafts, fitness facilities, hardware industry, aviation, etc.

**Advantages**

The surface clean. The flat bar steel with the process of adopting high pressured water for descaling ensures smooth and clean of surface of steel flat bar.

The steel flat bar is made by negative deviation rolling, however it is delivered as actual weights. So the rate of uses is higher as 1 to 5 percentage than steel plates’.

It could be manufactured according to the customers’demand, with fixed thickness, width and lengths. Meanwhile, reducing the cutting method and saving the time and process for customers; lower the consumption of labors and materials as time-saving, labour-saving and material-saving; avoid the process loss of row materials.
