Steel Coil

Your Leading Steel Coil Supplier

Tangshan Zhenxiang Plate and Strip Processing Co., Ltd. has become a comprehensive steel enterprise integrating plate and strip longitudinal shearing, hot-dip galvanizing processing, machinery purchase and trading, and logistics distribution. Our steel coil has many categories, including hot rolled steel coil, cold rolled steel coil, galvanized steel coil, PPGI coil, galvalume steel coil, stainless steel coil, etc. Steel coil is defined as sheet or strip of steel that is wound or coiled after rolling. It is manufactured by placing a slab into a continuous rolling machine to reduce its thickness until it forms a sheet. This sheet is then wound into coils. The uses of steel coils are diverse and wide-ranging.

Types of Steel Coil

Hot Rolled Steel Coil
Hot-rolled steel coils, are steel rolled at high temperature. This process imparts unique characteristics to it. It is a strong, durable, and cost-effective material for so many purposes. It is used to build frames and bridges.

Cold Rolled Steel Coil
Cold rolled coil is a flat steel product made by the cold rolling method. This is passing a hot rolled coil that has been pickled and oiled between a set of room-temperature work rollers after it has been unrolled.

Galvanized Steel Coil
Galvanising is process in which a protective coat of zinc is applied to steel. So, galvanised steel coils are steel sheets with zinc coating. This application of the zinc coat makes coils durable as it protects the coil from rusting.

PPGI Coil
PPGI is pre-painted galvanised iron, also known as pre-coated steel, coil coated steel, color coated steel etc., typically with a hot dip zinc coated steel substrate.

Galvalume Steel Coil
Galvalume steel coil is a type of steel sheet that has been coated with an alloy consisting primarily of aluminum and zinc. This unique coating provides a high degree of corrosion resistance, making it an ideal material for a wide range of applications, especially in environments that are prone to rust and corrosion.

Stainless Steel Coil
Stainless steel coils are flat strips of stainless steel that have been wound into a coil shape. They are manufactured from stainless steel sheets or plates and can be used in various applications across different industries.

Five Surface Treatment Methods for Steel Coil

Mirror treatment
Processing method: Through polishing technology, mechanical or chemical polishing methods are used to make the surface of the stainless steel roll as smooth as a mirror, reflecting a bright luster.

Drawing treatment
Treatment method: A layer of rough texture is formed on the surface of the stainless steel coil through mechanical or chemical methods, showing a brushed effect.

Pickling treatment
Treatment method: Chemical pickling is used to remove oxide scale, rust and other undesirable substances on the surface of the stainless

Remove black oxide
Treatment method: It mainly deals with the black oxide scale produced during the processing of stainless steel. Commonly used methods include sandblasting (shot) method and chemical method.

Surface coloring treatment
Treatment method: Through chemical oxidation, electrochemical oxidation, ion deposition oxide, high temperature oxidation or gas phase cracking, various colored films are formed on the surface of the stainless steel coil.

Usage of Steel Coil

Construction
Like many other metal materials, steel coils are also popular in the construction industry. They're used as materials for roofing sheets. building panels, pipes, walls, reinforcing bars (rebars), and structural components like beams, columns, and trusses.

Automotive
Steel coils can also be commonly used when producing various automotive components. These include car body parts, chassis components, and even exhaust pipes.

Packaging
While steel coils are most often unrolled, cut to size, stamped, and welded to produce metal cans, this is not the only way they are used in the packaging industry. Steel coils are also used to produce steel straps that secure packages and pallets during the transportation of goods.

Consumer goods
Quite a number of things you find in stores are actually made of steel coils. These include appliances like refrigerators, washing machines, and ovens, furniture like desks, chairs, and shelving, tools like hammers, wrenches, and saws, sports equipment like golf clubs, tennis rackets, and bicycles, and various kinds of hardware like nails, screws, and bolts.

Machinery
Many machine parts are made out of steel coils, like frames, bearings and shafts, gears, springs, and engine components. The benefit of steel coils in the machinery industry is how flexible they are—because they can be shaped into a variety of forms, there are so many standard and customizable machine parts they can be formed into.

Energy and electrical equipment
Steel coils are used in the construction of wind turbines and transmission lines for the electrical power industry. They are also used in the production of pipelines, boiler tubes, pressure vessels, and solar panels. Their strength and durability are key in ensuring that the products formed from steel coils are long-lasting and reliable.

Q: What are the advantages of your factory?

A: Our factory is equipped with a large number of high-precision production facilities, and they have passed the international ISO certification. Highly praised by customers at home and abroad.

Q: What is the best hardness test for steel coils

A: Rockwell C - typically used on materials with high hardness values, such as tool steels, castings and heat-treated materials.
Rockwell B - comes into play for softer material, including non-ferrous metals like aluminum, copper alloys, brass and softer steel.

Q: How do you store steel coils?

A: Steel coils should be stored on stable, level surfaces, either stacked on their side (eye to the sky) or upright in storage racks to prevent accidental rolling or falling. Racks and supports must be designed to handle the weight and dimensions of the coils.

Q: What precautions should be taken when loading steel coils?

A: Steel coils can vary in weight and size, so they must be dispersed throughout the vessel to ensure stability. Heavy coils should be placed on the bottom of the stack, while lighter coils should be placed on top. This arrangement will prevent the vessel from listing or capsizing during transport.
