About Yard

Rollock was founded in 1996 to manufacture and distribute Rollock clamps, Which utilize a proprietary mechanism that can be applied to a wide variety of clamping applications.  The company has since diversified in ferrous and non-ferrous metals processing and recycling, commercial analytical services, and the production of ferroalloys. Rollock has locations in Stoystown, PA and Johnstown, PA.  The main office is located in Stoystown - recently moved from Flight 93 to our current location on Rt. 30.  Before relocating to the current location in Franklin Borough, Rollock operated in Coopersdale.  Both locations accept ferrous and non-ferrous materials.  At the Johnstown location aggregate materials, such as anti-skid, 2-B, and sand, are available for sale (please call the main office at 814-629-9400 for more information).  Rollock prides itself with being honest.  Our truck scales and floor scales are tested at each location every year by the Pennsylvania Department of Weights and Measures.  All weights are punched on a ticket, which the 
customer receives.   

Scrap Specifications and Definitions

Scrapper’s #1 rule: ALWAYS check everything with a magnet!!!

General Information

*Check each piece with a magnet
*Grind the surface of questionable pieces. Steel is often chromed to prevent corrosion and will resemble brass; Die cast is often coated with a yellow coating which also resembles brass.

Yellow Brass

Yellow brass is the most common brass you will come across. It is used in belt buckles, plumbing, plaques, jewelry, marine hardware, musical instruments, and other things that call for an anticorrosive material. It can be painted, tarnished, or chromed so always grind the material to see its true colors. It is completely non-magnetic (a magnet should not stick).

Red Brass

Red brass is the second most commonly used brass found in most markets. It is generally used for non-corrosive, heavier applications. Red brass ground against an abrasive wheel will show a reddish color. Red brass cannot be chromed-all die cast must be removed. Red brass is also nonmagnetic.


General Information

*The most common uses for copper are for plumbing and electrical applications.
*Copper has a reddish appearance but can take on a green tarnish as it ages.
*All copper is non-magnetic and does not have a spark
Steel can be coated with copper to protect it from the elements (i.e. lightning rods and sheets)

#1 Copper

#1 Copper MUST BE CLEAN! There can be no foreign materials, paint, melted solder or attachments on the surface. Wire must be a pencil lead thick or thicker. Natural tarnishing is fine.

#2 Copper

#2 Copper includes copper tubing with solder, wire with shellac, hair wire, and borings. Can not be over 15% tin-coated, lead coated, or solder coated. No thin hair copper wire or burnt brittle wire.

Light Copper

Also called Sheet Copper. Copper roofing, flashing, kettles, pots, hanging artwork, and gutters can all be considered Light Copper.

Insulated Copper Wire
Insulated copper wire is identified by cutting back the material on jacketed electrical wire to expose copper.


General Information

*All radiators must be cleaned of steel

Auto Radiators

Most auto radiators are made of copper, tin, and lead. They are identified by the dark copper center and yellow tanks on either end. The radiator that cools the water in the engine is the auto radiator. Auto radiators are found in cars and trucks.

Aluminum and Copper Radiators

Found in air conditioning units. Before removing make sure that the CFC’s have been removed. To identify look for the aluminum fins with copper pipe running through the middle – all steel dividers should be cut off.

Aluminum Radiators

Found in cars and air conditioning units. They are all aluminum.

Heater Cores

Found in cars. Small in size, usually weighting three to four pounds. Yellow brass is the primary metal.

General Information

*Aluminum is a lightweight, non-corrosive metal.
*The color of aluminum does not change – a grayish color.
*To identify check for the following: no rust, non-magnetic, no spark, lightweight, and the unique grayish color.

Aluminum Siding

Aluminum Siding is removed fro houses. Aluminum gutters and spouting can also be sold with siding. Paint is fine, but all steel screws and rivets must be removed to be considered clean.
** Steel siding is also made so always check with a magnet.

Cast Aluminum

Cast aluminum can be identified by the rough texture found when broken from the mold in which it was created. Watch for magnesium and die cast – the have a darker grey color than aluminum; magnesium is lighter than aluminum and die cast is heavier

E.C. Aluminum

It is used in electrical applications. Busbar and wire are two products classified as E.C. aluminum. It is very soft and pliable – easily bent by hand.

New Aluminum

Is either square of round stock. There is not anything protruding from the main body of the material. Look for factory markings.

Aluminum Cans

Aluminum cans DO NOT have to be crushed. It takes approximately 18 cans to make one pound of cans.

Very distinctive dark grey color, non-magnetic, no spark, very soft, and very heavy. If not sure take a knife and cut a piece – it will carve off easily in a curl shape. If it chips it is too hard to be lead. Lead will also leave a mark on white paper.

Heavy Melt

At least ¼ inch in thickness. Much of the metal comes from demolished buildings, truck frames, and heavy duty springs. Prepared lengths are 3 feet by 2 feet, anything larger is considered unprepared.

Appliance Tin

Also known as Major Appliances, White Goods, and Shred. Any domestic or commercial device; including, but not limited to, a washing machine, clothes dryer, water heater, dehumidifier, conventional oven, microwave oven, stove, refrigerator, freezer, air conditioner, trash compactor, or residential furnace.

Whole Cars

We accept whole cars. The title must be surrendered at the time of sale. All tires should be removed or $10.00 per tire will be charged for disposal fee. The gas tank and battery should also be removed from the car – however Rollock does purchase both separately. The average car weighs approximately 3,500 pounds (Therefore as of 3/11/08 a car would be worth – on average – approximately $280.00).
