Is the C.H.I. Full View Aluminum a steel or aluminum garage door?

The name says it plainly: the C.H.I. Full View Aluminum Collection uses aluminum, not steel. That is not a coincidence or a trade-off. Aluminum is the standard structural material for full-view garage doors across the industry, and for good reason. When a door section is mostly glass, the frame has to be lightweight enough not to overload the opener and the spring system. Aluminum is about one-third the weight of steel at the same cross-sectional dimension. It makes a large glass door practical.

The choice of aluminum over steel also reflects the design intent of the Full View category: this is a contemporary door built for homes where light, transparency, and clean lines are priorities. Aluminum frames make that possible. Understanding what aluminum offers, where it differs from steel, and how it performs in Colorado is worth your time before buying.

Aluminum vs. Steel in Garage Doors: The Key Differences

Both aluminum and steel are common garage door materials. They serve different purposes well.

Feature	Aluminum (Full View)	Steel (standard residential)
Weight	Lighter	Heavier
Rust resistance	Natural (no coating needed)	Requires galvanizing or paint
Dent resistance	Lower than heavy-gauge steel	Higher, especially 24 ga
Glass area potential	Full-view sections practical	Limited by structural needs
Corrosion from road salt	Resistant	Can corrode if paint chips
Typical finish	Anodized or powder coat	Baked paint over primer

The critical advantage aluminum provides in a full-view door is structural efficiency at low weight. A two-car garage door in aluminum with full glass panels operates on the same spring systems as a standard steel door. The same opener works. That would not be possible with a steel frame of equivalent section size carrying the same glass load.

Steel doors remain the better choice when dent resistance is the primary concern. A 24-gauge steel panel resists hail impact better than an aluminum frame of similar section depth. For Colorado homeowners where hail resistance is the top priority, a steel door is the stronger material. The Full View Aluminum is not optimized for impact resistance. It is optimized for light, design, and corrosion resistance.

How the C.H.I. Full View Aluminum Is Built

The door's aluminum frame carries the structural load. Large glass panels fill the frame area. The glass runs the full height of each door section. That full-height fill is what makes the door look like a glass wall when closed.

Glass options: - Plain (clear): Full light transmission, direct street view into the garage - Tinted: Reduces glare and solar heat gain, partial privacy - Obscure: Frosted appearance, full privacy with diffused light

Frame finishes (10 standard options):

Clear Anodized, White, Almond, Sandstone, Brown, Bronze, Dark Bronze, Gray, Desert Tan, and Black, plus 188 powder-coat options for projects needing specific color matching.

Insulated and non-insulated versions are both available. The insulated version includes a panel fill between the glass and frame that slows heat transfer. The R-value for the insulated version should be confirmed with your dealer before ordering for a heated or attached garage, as manufacturer documentation does not publish a specific figure openly.

The frame finish does not fade, chip, or rust in the way paint can. The section warranty is a limited lifetime. Springs carry a 3-year warranty, and hardware a 6-year warranty.

Why Aluminum Makes Sense for Colorado Homes

Aluminum brings specific advantages to Colorado's climate that steel does not naturally offer.

Rust resistance: Steel corrodes when its coating is breached. Road salt from Denver's highway de-icing program runs from October through April. Salt spray migrates onto garage doors near busy streets. Steel doors require intact paint and galvanizing to hold off corrosion. Aluminum oxidizes naturally on its surface, forming a layer that stops further corrosion without any coating. That process is called passivation. The frame remains intact even if the finish is scratched.

Freeze-thaw stability: Colorado experiences dozens of freeze-thaw cycles between October and April, sometimes multiple cycles in a single day. Materials that absorb moisture and expand when frozen can develop alignment and sealing problems. Aluminum does not absorb moisture. It expands and contracts with temperature uniformly and predictably. A Full View Aluminum door installed correctly maintains its alignment through Colorado's temperature extremes better than wood and comparably to well-built steel.

UV performance: At Front Range elevations, UV intensity is roughly 25 percent higher than at sea level. Anodized aluminum finishes resist UV fading better than liquid-painted finishes over a long service life. For a door with clean, simple lines where any surface discoloration is immediately visible, that long-term finish stability matters.

Glass selection for Colorado exposures:

South- and west-facing garages face intense afternoon sun in summer. Tinted glass is the right call for those orientations. It reduces heat buildup inside the garage and limits solar glare. East-facing doors get morning light and can use plain glass without significant solar load. North-facing doors benefit from plain glass to let in as much natural light as possible given the indirect solar exposure.

What to Know Before You Buy

The Full View Aluminum is not the right door for every situation. Here are the honest trade-offs.

Hail: Aluminum can dent under severe hail. Colorado's hail seasons regularly produce quarter-sized to golf-ball-sized stones. A solid aluminum panel does not resist that impact as well as heavy-gauge steel. Homeowners in high-hail-exposure neighborhoods should weigh this risk. Glass panels in any full-view door are also vulnerable to direct hail impact. Check your homeowner's insurance coverage for garage door glass before ordering a full-view door in a hail-exposed location.

Insulation: Confirm the R-value of the insulated version with your dealer. Aluminum frames conduct heat more readily than steel, which means the frame area contributes less to overall thermal resistance than an all-steel panel at the same thickness. For an attached, heated garage where energy efficiency is a priority, a high-R steel door may outperform the Full View Aluminum on thermal metrics.

Frame finish and home style: The 10 standard frame finishes cover most architectural directions. Black and Dark Bronze frames are popular on contemporary builds in Denver's urban infill neighborhoods. Clear Anodized is the most minimal choice, letting the glass read as the primary design element. Dark Bronze is popular on traditional homes where an aluminum full-view door is being specified for a detached garage or workshop that needs to complement the main house.

Planning for glass privacy: Before ordering, walk through the garage's proximity to the street and neighbors. A garage that opens directly toward a busy sidewalk or a neighbor's driveway is a different privacy situation than one that faces a private court. Plain glass in a street-facing situation means your garage interior is visible to anyone passing by. Obscure glass eliminates that. Tinted glass is a middle ground. G Brothers can walk through this decision at the estimate so the glass choice fits how you use the space.

Spring sizing for aluminum doors: Aluminum full-view doors are lighter than comparable insulated steel doors, but they still require properly sized springs for safe and balanced operation. G Brothers checks spring calibration at installation and balances the door before completing the job. A door that is out of balance puts uneven stress on the opener and on the track hardware. Proper calibration at installation extends the service life of every component in the door system.
