20ft Conex Storage Container – Used, Yellow Gold Finish

A 20ft Conex Box for Sale That Is Easy to Find on Site

Looking for a straightforward 20ft conex box for sale? This used unit is exactly that, finished in a yellow-gold livery that makes it easy to pick out at the far end of a lot or across a field. Colour sounds cosmetic until you are directing a driver over the phone or telling a crew which box the fittings are in. Beyond the paint, it is a standard 20 ft steel container that gives you about 160 square feet of dry, lockable floor.

Buying used means accepting the marks that come with cargo service. What you get in return is shipping-grade steel at a price that leaves budget for a pad, a good padlock, and shelving.

Portable Storage Container Uses for a 20 Foot Box

The 20 ft size is popular because it fits where a 40-footer will not, and it still swallows the contents of a full garage.

• Tool and material security on active job sites
• Backyard or driveway storage during a renovation
• Sports clubs, schools, and community groups storing equipment
• Small business inventory overflow at a rented unit or yard
• Seasonal storage for mowers, snow gear, and outdoor furniture

Preparing the Ground and Taking Delivery

Give the container four solid bearing points — concrete blocks, railroad ties, or a gravel pad — level in both directions, and lift it slightly off the soil so air moves underneath and the underframe stays dry. Keep the door end facing the direction you will approach from. For the drop itself, allow the container length plus roughly 40 ft of straight run and about 15 ft of overhead clearance, and clear low branches beforehand. Delivery is a flat $500 to all 50 states, booked once your order is confirmed and quoted by route.

Frequently Asked Questions

Can I repaint the container a different colour?

Yes, and it is a common weekend job. Wire brush or pressure wash the surface, treat any bare metal with a rust-inhibiting primer, then use a direct-to-metal exterior enamel. Two lighter coats hold up better than one heavy one. Painting the roof a reflective colour also slightly reduces heat build-up inside during summer.

What lock should I use on a used container?

A hardened puck-style padlock inside a lockbox is the standard answer, because there is very little shackle exposed for a bolt cutter to reach. If this unit does not have a lockbox fitted, one can be welded on inexpensively by a local fabricator. Locks are supplied by the buyer, not included with the container.

How do I stop condensation inside?

Keep the factory vents clear, avoid storing damp items or wet timber, and raise stored goods off the floor on pallets so air circulates. In humid climates, adding a vapour barrier, insulation, or a few desiccant units makes a noticeable difference. Sweating is caused by warm moist air meeting cold steel, not by a leak.
