Added Security
Add full insulation types, drywall, and various flooring options for comfortable, finished interiors, maximizing the usable space. High-efficiency insulation options like spray foam or rigid panels ensure climate control, while drywall and a selection of flooring finishes transform the container into a fully customized, comfortable environment.
Install compact HVAC and electrical wiring for climate control and power, including various lighting solutions. Efficient, space-saving mini-split HVAC systems ensure optimal climate control, while professional electrical wiring and LED lighting provide necessary power and bright, energy-efficient illumination for any application.
Add man-doors for easy access, and window cutouts with security bars or skylights for natural light. We install high-security steel personnel doors for convenient and protected entry, along with window cutouts—complete with security bars or roll-down shutters—and skylights to maximize natural illumination.
Design custom workspaces with built-in desks, shelving, and racking systems to optimize the smaller interior. We design fully custom layouts to maximize every square foot, integrating features like built-in fold-down desks, adjustable heavy-duty shelving, and specialized racking systems to perfectly organize the interior for any intended purpose, from an office to a mobile workshop.
Customize your exterior with specialized paints, including the color of your choice and professional branding applications. We apply industrial-grade coatings and a full spectrum of custom colors, including durable marine-grade and specialized anti-graffiti paints, and can professionally apply your company's logos and branding directly to the exterior for maximum visibility.
Container security can be significantly enhanced with lock boxes for preventing bolt cutter access, heavy-duty steel doors and window bars, and advanced locking mechanisms like tamper-proof puck locks. We also offer installation of alarm systems and motion-sensor lighting for comprehensive protection of your valuable contents and assets.

Frequently Asked
Questions
What is the primary benefit of a 20-foot open side container over a standard container?
The main advantage is the ability to open the entire long side, providing incredibly wide access. This is perfect for loading oversized items, creating a large entry point for customers (like in a retail setting), or opening up a space for natural light and airflow, which is great for workshops or event booths.
How is the structural integrity maintained when such a large section of the side is removed?
Our container fabrication process for open side units includes careful structural reinforcement around the new opening. We add steel framing and supports to ensure the container maintains its strength and durability, adhering to safety standards even with the large side access.
Can the open side be fully enclosed or modified with different door types?
Yes, the open side can be customized. We can install various door types, including bi-fold doors, glass sliding doors, or even roll-up doors, allowing you to enclose the space when needed or create different entry/display configurations.
Are there any special considerations for delivering a 20ft open side container?
While the 20-foot length is manageable, the open side design doesn't typically impact delivery methods more than a standard 20-foot unit. However, we always perform a delivery site assessment to ensure clear access for placement, especially if you plan to open the side fully upon arrival.
What are some common uses for a 20-foot open side container?
These units are popular for pop-up shops at beach events, mobile food stands, or open-air workshops where natural ventilation is a plus. Their Corten steel construction resists salt air, and with options for insulation types, they can be comfortable even with the side open.
