Magazines
Tread Corporation a leader in the manufacture of explosive storage facilities
and has supplied fine quality permanent and portable storage magazines to the blasting industry since 1957
All Tread Type 2 Portable Magazines are built to meet rigid government specifications as set forth in the Bureau of Alcohol, Tobacco and Firearms regulations in Title 27 Code of Federal Regulations, Paragraphs 55.208, "Construction of Type 2 Magazines".
These magazines are constructed from 1/4" hot rolled steel plate which is manufactured to our specification by some of America's leading steel producers. Wood linings are milled to full thickness from the finest Appalachian hardwoods, purchased in truck load quantities. We manufacture our own ventilator covers, hasp and staples, padlock covers, hinges, and skids.
Hinge pins are hardened and hinge barrels and lock staples are made from alloy steel for extra protection. The nose of the skids are beveled at approximately 45 degrees for easier moving. There are openings on the ends of the skids, as well as lift rings on the top of the magazine, for the attachment of chains or cables for moving. The doors are sheared from the side of the magazine to provide a close fit and each door is provided with drip protection from the weather. The first inner layer of hardwood is bolted securely in place with successive layers attached by air staples. All Type 2 Portables have stand-off strips on the inside layer of hardwood at the screened ventilators, thus preventing the packing of the explosives from hindering ventilation.
