INDEPENDENT TUBE MOUNTING

Self-supporting structural steel tubes are furnished with
grilles when so specified, to permit installation independent
of adjacent construction. This design is particularly suitable
to enclosed mall requirements. Tubes are anchored to floor
slab, and to steel beams or trusses above.

CITY-GATES was chosen by a world wide leader in the construction management industry to provide overhead coiling doors to well known retail store chain in the South East. The slide show you are looking at is one of fifteen trailers that were needed to deliver 225 doors to various sites throughout the South Eastern United States. The customer placed an order for our Model CG300 rolling steel doors. All of the doors were constructed from 20 gage galvanized steel slats, angle iron bottom bars, angle iron guides, counter balanced torsion springs, chain hoist operated and motorized. The size of the doors ranged from 6 feet wide to 35 feet wide. Please contact our special contracts department if you have a similar requirement.
