hanging file folders heavy duty

Heavy-duty hanging file folders are made from a mix of materials, including pressboard, PET (polyethylene terephthalate), aluminum, and polyethylene.

Listings commonly show both Letter and Legal sizes for heavy-duty hanging file folders and boxes, with some products specified as Letter Size and at least one as Legal Size.

Capacity varies by product; the listings include sheet capacities ranging from about 50 sheets up to 750 sheets, with examples at 50, 150, 600, and 750 sheets.

Reinforced and tear-resistant constructions are used, such as tall tear-resistant sides, polylaminate-reinforced tops, reinforced bottoms with pressboard inserts, and expandable rip-proof tape gussets to support bulky projects.

Listings describe built-in tension springs, stronger rods and hooks, and rods designed to bend less—features that keep folders riding on rails securely and allow smoother sliding.

Package quantities vary by product. Listings include packs of 25, packs of 20, and single-unit packs (examples listed as 25, 20, and 1).

Listings show several common overall sizes, for example: 13" × 11.25", 14" × 10", 13" × 9.56", and 12.6" × 10.3".
