ASTM A36 Jis Ss400 Q235 Hot Rolled Structural Mild Plates For Construction And Fabrication
ASTM A36 PLATE STEEL is a structural quality product designed for use in welded, bolted, or riveted fabrications such as oil rigs, buildings and bridges. Produced with a min. yield of 36,000 psi, A36 plate can be used in the construction of a variety of lightweight structures and equipment where good welding properties are important.
Standard thicknesses and plate sizes of each plate condition in SA516 are as follows.
| Grade | Condition | Thickness | Prefered Width | Length |
| Q235 | In Coil | 0.5mm to 6mm | 2438 To 3048mm | Random |
| Q235 | Sheet / plate | 3mm to 50mm | 30 up to 4500mm | up to 18 m |
Technique : Hot rolled , Cold rolled as per requested .
*Length restrictions exist, depending on plate weight and mill capabilities.
other Dimension is also available upon request

This is the most common and simple finish and the first step to making steel plates and sheets. A steel slab is heated, typically to 1,700 degrees F, and passed through a series of rollers - each set of rollers making the slab thinner until the desired thickness is achieved. Then the steel is allowed to cool to room temperature and cut to size or rolled into large coils.
Hot rolled steel is the easiest and cheapest sheet steel to find. It is fairly ductile, and thinner sheets can be easily formed with hand tools. Its dimensions are less refined compared to cold rolled steel.
A roll or sheet of hot-rolled steel is dipped or passed through a pickling bath. A solution of very strong acid removes the scale and dirt from the sheet or plate, leaving the raw steel exposed. It is then passed or dipped in an oil bath to protect the raw steel from oxidation, which would begin immediately without protection, especially in humid environments.
Steel that has been pickled and oiled has the same material properties as straight hot rolled steel but is cleaner to work with and easier to clean for painting.
Hot rolled steel sheets or plates, that have previously been pickled and oiled, are again run through a series of rollers without the addition of heat. This compression of the steel at room temperature causes it to become work hardened.
To produce the finished product, the steel is then annealed and tempered.
Cold rolled sheet or plate is put into a furnace and heated to a temperature below the melting point of the material. The steel is removed from the furnace and allowed to cool to room temperature. When heated, the steel grain realigns and some of the effects of work hardening are diminished.
Annealed steel is passed through one more set of rollers. These rollers are primarily to refine the finish further and diminish slight deformities or warps in the steel.
Cold rolled steel is made to much tighter dimensional tolerances and the surface is more uniform and refined. Typically the edges are quite square. This steel is harder and stronger but won't hold shape as well as hot rolled steel when it is bent. It is less ductile and when bent, the deformed zones are more likely to spring back than to take the bend. Steel sheets or plates that make it to this stage are ideal when looks and strength are important.
Specialized coatings can be applied to the surface of the steel via dipping or electroplating. Most commonly zinc is applied to the surface to produce what is known as galvanized steel. Learn more about the galvanizing process
