Rolling sheet roll-up doors are often confused with rolling steel slat doors. From a distance, they look the same. They both have metal curtains that roll up around a barrel covered by a hood (not all models have hoods). The main difference is that rolling sheet doors are a continuous unit that is one vertical unit whereas rolling steel doors are interlocking slats on a curtain that attaches to a spring barrel inside a hood. The guides for rolling sheet doors are thin gauge metal whereas their counterpart has guides that are structural steel angles. The curtain on rolling sheet doors are lower gauge metal and rolling sheet doors are never fire-rated.
Rolling sheet doors are less expensive and lightweight compared to a rolling steel slat door, which is used for medium and heavy-duty applications. Storage facilities all use rolling sheet doors since they need security and aesthetic look but not the heavy-duty option. These doors are low maintenance, easy to install and can easily be pushed up. Door operation options include crank, push up, chain hoist and, for ease of use on larger openings, a commercial garage door operator is incorporated.
