Sheared Hot Rolled Steel Sheet Plate 16 Gauge Custom:

Steel sheets and plates are made by rolling a slab of steel through a series of rollers until the desired thickness and material properties are achieved. Each stage in the rolling and finishing process produces a salable sheet or plate with distinct finish and properties.

Hot Rolled Steel Sheet Plate

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.

Cold Rolled Steel Sheet Plate

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.

Annealed Steel Sheet Plate

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.

Galvanized Steel Sheet Plate

Galvanized steel is coated with zinc to create a physical and chemical barrier that prevents corrosion. Galvanized steel has a longer lifespan and reduced maintenance costs over its life.

There are two types of Galvanized steel available, Hot-dipped and Electro-galvanized. The major difference between these two types is the production method.

A few of the most common grades of steel plates and sheets are:

A36 - a low carbon steel with good strength, formability that can be securely welded with a minimum yield strength of 36,000 PSI

A572-50 - higher strength steel with a minimum yield of 50,000 PSI and increased corrosion resistance

A516-70 - steel with a minimum tensile strength of 70,000 PSI that is generally used in pressure vessels and boilers

AR400 - abrasion resistant, quenched and tempered alloy steel with a high level of hardness, making it brittle and so it is not intended for structural applications

A588 - also known as Corten, this steel weathers well, forming a stable rust-like appearance that eliminates the need for painting
