What is stainless steel?

Stainless Steel is an iron-containing metal alloy made up of two or more chemical elements. It comes in more than 57 stainless steel alloys along with numerous proprietary alloys.

How is steel delivered?

Con-Tech built its reputation on reliably delivering flat roll steel products when you need them, shipped directly from the mill to your plant or JIT delivery by drawing from our inventory from world-class suppliers.

Which steel products does Con-tech offer?

Con-Tech provides steel mill products for steel drums and other applications including cold-rolled, galvanized, tin plate coils, as well as blanks from hot and cold rolled and steel plates.

Does Con-Tech provide hot and colled rolled steel?

Con-Tech specializes in importing both hot roll steel coils and cold roll steel coils. Our diverse range of hot rolled steel coils and cold roll steel coils are used in the manufacturing of 55-gallon steel drums and other containers, as well as in numerous other industrial applications.

What are spiral ducts?

Spiral Ducts are specialized metal housings employed for HVAC airflow.

How are most spiral ducts fabricated?

Galvanized steel is used for many applications in the HVAC manufacturing process for the fabrication of spiral ducts used for HVAC airflow housings.

What is Stainless Steel?

Stainless steel is an iron-containing metal alloy made up of two or more chemical elements.

How many different types of stainless-steel alloys exist?

Stainless steel comes in more than 57 stainless steel alloys along with numerous proprietary alloys.

What industries use stainless steel?

Stainless steel is used in innumerable applications and industries. Stainless steel is found in marine and shipbuilding, industrial packaging and containers, bulk materials handling equipment, building exteriors and roofing, automobile components, chemical processing plants, pulp and paper manufacturing, petroleum refining, water supply piping, consumer products, pollution control, sporting goods, food handling, storing, cooking, and serving equipment and transportation, to name just a few.

What are the key properties of stainless steel?

As an iron-containing alloy—a substance made up of two or more chemical elements—stainless steel is stain and rust resistant.

Why is stainless steel preferred for marine applications?

Stainless steel is one of the materials that is preferred for marine hardware as it is highly resistant to rust and less likely to corrode in saline conditions. Its long-lasting capabilities make it preferred in many marine applications.

What is electrogalvanized steel?

Electrogalvanized steel is a steel to which corrosion protection is added by bonding a zinc layer to it.

How is electrogalvanizing of steel accomplished?

Electrogalvanization is done when raw steel is placed into an electrolytic saline/zinc liquid and subjected to an electrically charged zinc anode and steel conductor. Current flows from the zinc anode, through the solution, and into the metal cathode. Tiny particles of zinc are dissolved in the electrolytic solution and bond to the surface of the metal.

What the results of electrogalvanizing of steel?

Electrogalvanized steel has a layer of zinc coating for protection and a shiny finish.

What are different types of electrogalvanized steel?

Electrogalvanized steel comes in a variety of forms including in electrolyte zinc coated, electro-galvanized, galvennealed and galvalume, hot-dip galvanized and aluminum-zinc alloy coated steel.

How is hot dipped dip galvanized steel made?

Cleaned and rinsed raw steel is placed into molten zinc at a high heat which bonds the zinc into a thick dull coating over the steel.

Why would hot dipped galvanized steel be used instead of electrogalvanized steel?

Hot dipped galavanzed steel is used when durability and longevity are sought while electrogalvanized steel for items not expected to withstand the tests of time.

Is electrogalvanized steel rust proof?

Rust prevention in galvanized steel will depend both upon the nature of the zinc coating and environmental humidity.

What is the difference in price between electrogalvanized steel and hot dipped galvanized steel?

Hot dipped galvanized steel can be two to three times the cost of electrogalvanized steel as it will be more long lasting.

Galvalume is a coating consisting of zinc, aluminum, and silicon that is used to protect the metal from oxidation.

What is galvannealed steel?

Galvennealed Steel is steel processed by galvanizing followed by annealing.

What are the benefits of galvannealed steel?

Galvennealed steel is easier to paint and harder and more brittle than galvanized steel.

What is hot rolled steel?

Hot Rolled Steel is steel which is heated to just beneath its melting point and then repeatedly subjected to rolling, making it thinner and longer.

What are the benefits of hot rolled steel?

Hot rolled steel is softer and more malleable.

What are the uses of hot rolled steel?

Hot rolled steel is perfect for larger steel shapes like structural beams and rail tracks, sheet metal and parts that need to be molded into very precise or distinct shapes.
