Water and Power

Recycling steel scrap is a major part of the steel industry, but the industry doesn't stop at just using recycling steel scrap; about 95% of water used in North America for making steel is recycled. Recycling steel also saves the equivalent energy to power about 18 million households for a year.

Standard Industrial Corp Model AS500-10 Shear

The Old Shear
 The New Shear

Tell Steel offers several different steel and aluminum cutting services ranging from band saw to plasma cutting. Shearing sheet metal and thin plate has been a service Tell Steel has offered for years, and with cutting steel comes a lot of wear and tear on machinery. After years of service one of the shears has now been replaced. The new shear is a Standard Industrial Corp Model AS500-10 Shear. Its capabilities are abundant and it will fit perfectly in with the demands at Tell Steel.  It is a 100% Made in the United States of America guillotine style shear. 
While many competitors use a Swingbeam/Rocker Arm, the power and precision of a straight line cut of the guillotine style shear is far more advantageous. In a guillotine style shear the drive system makes sure the upper blade comes down on the material in a straight line. This is due to the linkage being driven directly above the metal being cut.  In comparison, a Swingbar/Rocker Arm styled shear has the blade come down in an arc or “swing” motion.  The system pivots the blade from one side of the end frames and brings the blade down in a swinging movement.  In this process, the top blade moves in relationship to the metal being cut while in a guillotine style it never moves in relation to the metal.
There are some crucial factors in providing the best cut possible and some of them include the hold down system and its capabilities to hold the material in place, the angle of the upper blade to the steel as the blade cuts it, and the strength of the drive system.  The Model AS500-10 has all the crucial factors for providing the best possible cut as well as many additional features.  It is 80,000 PSI capacity rated, ensuring to have enough power for all of the cuts needed by Tell Steel, Inc. It also has a strong sturdy frame and high tonnage to hold down the steel being cut. 
This shear comes equipped with many features including an 8’ squaring arm, manual swing-away backstop, infinitely variable power blade gap adjustment and a protractor for angle shearing.  The following are some other interesting specs of the shear:

Recycling Steel Cans

The United States uses over 100 million tin and steel cans in a single day. Strong magnets are then used to collect the tin and steel cans from the rest of the trash. These magnets recover about 9,000 cans every minute.

Different types of steel have different purposes and uses. Because of this, Tell Steel Inc maintains an inventory of 18 different types of metal plate. All of which can be custom cut by Tell Steel in its facility and delivered for free the next day.

Ocy-Acetylene

The Oxy-Acetylene welding and cutting process is one of the oldest in the world. It requires acetylene gas to be mixed with pure oxygen instead of air. This combination boosts the flame temperature from about 2,000°C to about 3,500°C. It is sometimes called the “Gas Axe”.

A-36 Steel Bar, Plate and Shapes

ASTM A-36 is a general purpose structural quality low carbon steel without advanced alloying. It has good forming, weldability and mechanical properties and easy to fabricate using structural methods like mild cold and hot forming or welding.  A-36 specifications for standard bars, shapes and plates 8” or less in thickness maintain yield strength of 36,000 psi and an ultimate tensile strength of 58,000 to 80,000 psi. Elongation in 2” is a minimum of 23%. This material is easily welded using all welding processes. Commonly produced in sheet, plate, bar, and structural shapes, its intended use is riveted, bolted or welded construction like that of bridges and buildings and for general structural purposes where aforementioned A-36 specifications are required.
