Aluminum Glass and Storefront Doors
Full-view aluminum sectional doors for restaurants, dealerships, fire stations, and modern storefronts.
We specify, install, and service every aluminum full-view door from Century Avenue using our own crews. We cover 11 Maryland counties, handling everything from a single restaurant wall to a row of fire station bays. A full-view door turns a patio wall into an open room, a dealership bay into a showroom, and a fire station front into daylight. You can choose the glass and frame to match the building. The complete Overhead Door aluminum line is here: the narrow stile 511, the wide stile 521 up to 26 ft wide, the springless EverServe 521S, and the frameless 522.
Aluminum doors 511, 521, and 522 carry a one-year limited warranty on all parts and components, with three years on the optional powder coat finish. The EverServe 521S is warranted for 24 months or 300,000 cycles, whichever comes first, on a published service schedule. It carries the same three years on powder coat.
Narrow stile aluminum full-view door
Model 511
Model 511 is the narrow stile aluminum full-view door, sized up to 16 ft 2 in wide by 16 ft 1 in high. Its 21/32 in center stile makes it sleek: the frame steps out of the way so the opening reads as glass. Sections are 1 3/4 in extruded 6063-T6 aluminum. Stiles and rails are held by 1/4 in through-rods on galvanized steel hinges and fixtures. The frame includes a 2 3/4 in end stile, a 2 3/8 or 3 3/4 in top rail, and a 2 3/8, 3 3/4 or 4 1/2 in bottom rail. Double strength glass is standard. Options include tempered, obscure, Low E, Solar Bronze, wire glass, acrylic, Clear Lexan, and multi-wall polycarbonate. You can choose 1/2 in insulated units for a conditioned opening, or solid aluminum panels where a section should be blind. Clear anodized is the standard finish. Bronze anodizing, black anodizing, and about 200 RAL powder coat colors are optional. Pull rope is standard. A chain hoist or an electric operator is optional. It runs on 2 in track, with 3 in available, and 10,000 cycle springs, with 25,000 to 100,000 cycle options.

Full-view aluminum sectional door
Model 521
Model 521 is the full-view door for openings where light and visual access are the point. It is the largest in the line at 26 ft 2 in wide by 20 ft 1 in high. A wide 2 11/16 in center stile and 3 5/16 in end stile carry the larger glass. Sections are 1 3/4 in extruded 6063-T6 aluminum tied by 1/4 in through-rods. The glazing choices match the 511 and add impact polycarbonate, which only the 521 takes. Stiles and rails can be polyurethane filled on doors up to 18 ft 2 in wide. With 1/2 in insulated units, the door tests to a U-factor of 0.30 with clear, tempered, or obscure DSB, and 0.28 with Low E, verified per ANSI/DASMA 105. Clear anodized is standard. Bronze anodizing, black anodizing, and about 200 RAL powder coat colors are optional. Pull rope is standard. Options include a chain hoist, an electric operator, a pass door, exhaust ports, higher-cycle springs, and a wind load and impact rated build under Florida Building Code approvals. It is the full-view door our crews install most often on fire station bays and service shops around Baltimore.

EverServe springless full-view door
Model 521S
Model 521S EverServe is the springless 521. It provides the same maximum light and visual access in a sectional aluminum door up to 20 ft 2 in wide by 18 ft 1 in high. It features the wide 2 11/16 in center stile and a 3 3/4 or 4 1/2 in bottom rail. There is no counterbalance spring to break or retension. The sections are 1 3/4 in extruded 6063-T6 aluminum, clear anodized or white. It offers the 521 glazing choices and the same tested U-factor of 0.30 with insulated DSB and 0.28 with Low E. A direct drive gear, motor, and brake assembly turns the shaft. It includes a built-in brake against uncontrolled travel and a hand chain for power outages. It runs on 230 V three-phase power as standard. The floor-level controller carries self-diagnostics, a digital readout, a timer to close, a cycle counter, and an open, close, and stop station. It opens at up to 15 in per second. It is rated for 300,000 cycles, 30 times a standard sectional door. It ships with a monitored sensing edge and photoelectric sensors. Track is 3 in, side mounted for vertical lift. Wind load builds use the 521 FBC or TDI approvals up to the door's full size.
