20ft Open Side Shipping Containers for Sale 

A 20ft new open side shipping container — also called a full-side access container or side-opening conex box — is a factory-fresh steel unit you own outright with bi-folding doors along one full side for loading wide, tall, or frequently accessed cargo. Standard end-door containers cannot match the loading efficiency of full-length side access.

What makes open side different? Built from corrosion-resistant Corten steel to ISO standards, this one-trip container has made only a single transit and arrives in excellent condition. It retains full cargo doors on one end plus the full-side opening — versatile access for pallets, furniture, machinery, and inventory that needs regular rotation.

Ideal for retail stockrooms, event equipment staging, warehouse cross-docking, construction material access, and any workflow where drive-up side loading saves time. Customization options like additional doors, windows, and HVAC are available through our fabrication team. Units ship in stock for nationwide delivery, giving you secure steel storage on a timeline that matches project deadlines without waiting on custom lead times.

Buy your 20ft new open side container online now while it is in stock, or rent this size from $209/month — both delivered in 3-7 days nationwide. Pricing, specs, and FAQs are in the product tabs.

We offer two types of trucks for container delivery:

Tilt-Bed Truck
Ideal for easy offloading without equipment.
Requirements: 65 ft of straight clearance, 12 ft width, and 16 ft vertical clearance.

Flatbed Truck
Best if you have on-site equipment (like a forklift) for unloading.
Requirements: 65 ft of straight clearance, 12 ft width, 14 ft vertical clearance, and side access for unloading.
You will need a forklift rated for at least 10,000 lbs to remove the container.

Site Preparation
Before scheduling delivery, please ensure:

• Clear, unobstructed access for the truck.
• No overhead obstacles like trees, power lines, or structures.
