Glossary of Terms
#1 HMS- wrought iron and/or steel scrap π inch and over in thickness. Individual pieces not over 60×24 inches (charging box size) prepared in a manner to insure compact charging.
#1 Bundles- New black sheet scrap, clippings or skeleton scrap, compressed or hand bundled, to charging box size, and weighing not less than 75 pounds per cubic foot. (hand bundles are tightly secured for handling with a magnet.) May include Stanley balls or mandrel wound bundles of skeleton reels, tightly secured. May include chemically detinned material. May not include old auto body or fendor stock. Free of metal coated, limed, vitreous enameled, and electrical sheet containing over 0.05 percent silicon
#2 Bundles- Old black and galvanized steel sheet scrap, hydraulically compressed to charging box size and weighing not less than 75 pounds per cubic foot. May not include tin or lead-coated material or vitreous enameled material.
Baler- Balers compress saleable ferrous scrap into a more uniform, rectangular shape (sometimes referred to as a “log”) and enable scrap metal recyclers to move baled material more efficiently from the yard to the shredder or to the mill, depending on a number of factors.
Busheling- Clean steel scrap, not exceeding 12 inches in any dimensions, including new factory busheling (for example, sheet clippings, stampings, etc.) May not include old auto body and fender stock. Free of metal coated, limed, vitreous enameled, and electrical sheet containing over 0.5 percent silicon.
Clips- non coated or non-painted- shredded 1000 series carbon steel clippings or sheets. Material should have an average density of 60 pounds per cub foot.
End Dump- There are three basic types of end dump trailers; frameless, full frame,
and quarter frame. On a standard frameless dump trailer, the suspension
and wheels are rigidly connected to the body so that when it dumps only
the rearmost wheels stay on the ground and the trailer body rotates about
the point where the tires contact the ground. A rigid structure (dump
block) engages the rear axle at the spring end cap early in the dump cycle
(approximately 10-15 degrees into the cycle) and then transfers the point
of rotation from the trunnion tube to the rear axle and tire. As a result,
the rear end of the trailer significantly drops down during dumping.
Ferrous Metal- Ferrous metals include steel and pig iron (which contain a few percent of carbon) and alloys of iron with other metals (such as stainless steel.)
Non-Ferrous- The term non-ferrous is used to indicate metals other than iron and alloys that do not contain an appreciable amount of iron.
Plate and Structural- cut structural and plate scrap, 5 feet and under. Clean open hearth steel plates, structural shapes, crop ends, shearings, or broken steel tires. Dimensions not less than π inch thickness, not over 5 feet in length and 18 inches in width, Phosphorus or sulphur not over 0.05 percent.
Processor- grades of scrap prepared especially to meet with steel mill or foundry requirements, individual specifications to be agreed on between consumer and supplier.
Punchings- The small part a machine punches out of a larger piece of metal sort of like a cookie punch out of a rolled out dough. The cookie is punch and the skeleton is the charging clip.
Roll-off boxes- A metal box that is used to store loose material. Usually 20′ long and 8′ wide, heights vary 4′-8′ tall. Roll-off boxes are designed to roll the box on and off the truck using steel rollers on the box itself. These boxes can usually hold up to 17 tons of material.
Shear- is a metalworking process which cuts stock without the formation of chips or the use of burning or melting. Strictly speaking, if the cutting blades are straight the process is called shearing; if the cutting blades are curved then they are shearing-type operations. The most commonly sheared materials are in the form of sheet metal or plates, however rods can also be sheared. Shearing-type operations include: blanking, piercing, roll slitting, and trimming.
Shredded scrap- Homogenous iron and steel scrap, magnetically separated, originating from automobiles, unprepared no1 and no.2 steel, miscellaneous baling and sheet scrap.
Shredder- a machine whose purpose is to shred material such as automobiles and home appliances into fine particles normally in a time frame of 4-7 seconds.
Tilt Hoppers- Pivot style container that tilts for loading scrap into a roll-off box.
Torch- In construction usage, a torch is a small hand-held burner which makes a hot flame, usually fueled by oxygen and either acetylene or propane, that is used for either cutting or welding metals, particularly iron and steel.
Turnings- Small cork screw like metal shavings. Generally produced by machine shops when metal is spun on a lathe.
