Can I get different colors?

Yes. Our standard colors are black, white, gray, medium and dark blue, harvest yellow, red and deep green. View color options.

What colors can I get?

There is really no limit to what we can do provided the color the customer requires is manufactured. View color options.

Why the different colors?

The different colors enable many of our customers to keep track of what they have stored in different containers easily without having to open them. They can glance at say, 50 drums, and easily identify what each contains.

What type of linings do you have?

Our standard linings are epoxy phenolics (both red and buff color), phenolics (both reddish and olive color), and modified phenolics (also reddish in color). All of our linings are food grade but their properties vary substantially, as does their compatibility and their composition.

What are the different kinds of gaskets?

There are a huge variety of gaskets both in material and profile (shape). Examples of different materials are EPDM, neoprene, Teflon, rubber and cellulose. All gaskets have differing properties that make them more suitable for some applications rather than others. Gaskets also vary substantially in terms of performance, specifically the profile/shape which affects the UN rating of the container, so their impact on the overall package can be very dramatic. It is important to note that a United Nations certified container must use the tested gasket in order not to invalidate the test certification.

What gasket will work with which container?

A number of gaskets may work with a particular container, but if the container is going to be used for the shipment of dangerous goods then the gasket must be tested with the container on which it is to be used, as it is an integral part of the container. There is no hard and fast rule on what gasket / drum combination are compatible, it is however not permissible to change one gasket type for another unless the container has been tested with both.

How does the bolt ring work?

A bolt ring is a closure ring that holds the cover on to the body of the container by encompassing the cover and the top of the container in a groove. This ring is then tightened by a bolt that pulls the ends of the rings together. A calibrated torque wrench is used to confirm proper closure.

How does the Leverlock ring work?

The Leverlock ring holds the cover on to the container with a latch (or toggle) that is pulled from one side to the other and applies torque to the two ring ends in a similar fashion to the bolt ring. No torque wrench is required to confirm proper closure.

What is an open head container?

Open head containers, also called 1A2 drums, have a fully removable cover secured with a Leverlock or bolt ring closure.

What is a closed head container?

Closed head, also known as tight head or 1A1 drums, have a non-removable top. Access to the container is via 2" and 3/4" plugs in the top of the container.

What's the difference between an Open Head and a Tight Head container?

An open head container is one in which the cover of the container can be completely removed. A tight head container is one where the cover is an integral part of the container and is non-removable (and access is only via the plugs).

What is a bolt ring?

A bolt ring is a closure device used to secure a cover to the body of an open head container. This ring requires a nut and bolt to secure the closure.

How is the lining put on the container?

The interior lining is sprayed on to a container in an interior-lining booth. The shell of the container rotates and as it rotates the interior is coated with a coating that is sprayed from a nozzle inside the container. The container is then oven-baked for a specified time and temperature.
