There is a luggage storage service a short one minute walk from Union Station in downtown Denver - LUGDEN. You can make a reservation online - lugden.com, call - (303) 747-5600, or show up as a walk-in. They offer hourly, day, overnight and weekly bag storage. Great place to store your luggage if you're on a layover from Denver International Airport, or going to a concert, or headed to a Rockies game at Coors field and want to enjoy yourself without having to lug your bags around.
AIS Industrial & Construction Supply’s locker division also handle heavy-duty metal lockers for the unique needs of Law Enforcement and Fire Protection professionals. A dual locker system provides a single tier locker with a vertical partition separating the bottom into two compartments. This works great for situations where work clothes and street clothes need to be kept separate.
Terry, there are many storage unit places closer to the airport, but then of course you'd have to rent a car. DIA Self Storage, for example, is less than 10 miles away. You can google map Denver International Airport, then "search nearby" for "self storage units" if you think that's something you might want to do. http://www.coloradoselfstorage.com/
Wilderness Exchange is within walking distance of Union and they require you leave a bag with them when you go into the store, they may be willing to stash your bag for a few hours. No guarantee on that, but an option if you can't find anything else. They are only open 10am-6pm on Sundays, so you may have to wait around a bit or pick it up early depending on when you get there and will be leaving.

Material: steel is the traditional material; but wood, plastic, or laminate are sometimes used. Plastic or laminate lockers are sometimes advocated in environments, such as near swimming pools, where moisture accumulation may cause steel lockers to rust over time. They can also be used in external applications where internal space is not available.
Stepped/2-step lockers are two-tier lockers, usually available only in 15-inch (38-cm.) width; but the compartments and their doors have an L-shaped cross-section, which causes the division between the doors to follow a zigzag pattern. This configuration enables more hanging height to be included in both upper and lower lockers; but part of each compartment (the lower part of the upper one and the upper part of the lower one) will be only half the usual width of two-tier lockers.
With the same standard features as the Traditional line, the Traditional Plus Collection is intended for more rugged applications. Available in single-, double- or triple-tier configurations, this collection features 14 gauge doors with 16 gauge full-height reinforcement channels, frame-secured 11 gauge frame hooks with protruding padlock hasps, and a maintenance-free, single-point latching system.
