About Gateway Engineering
Scrap sellers in and around South Sioux City, Nebraska can take material to Gateway Engineering, an industrial steel and scrap business in Dakota County. The site works with walk-in sellers and small contractors, and provides a paid intake channel for scrap metal across the surrounding county. Sellers will find aluminum, brass, copper, and lead on the posted list of accepted categories. The yard self-reported these to the directory, which makes the list a working baseline for the standard intake mix on a given inbound day at the gate. On the contact front, a phone line, a website, and an email contact are on file. Operating hours are posted in the directory entry, which together form the yard's published-facing schedule and channel mix as filed with the directory, and give sellers a working sense of how to reach the site before driving over. On larger loads, calling ahead with approximate tonnage and material spec lets the yard quote a working per-ton price and book gate timing. The site can plan inbound capacity, and the contractor walks in with a number rather than waiting at the scale on the day of the drop-off and the drive over.
