Built for Winter: Boxwell’s Snow Load Strength 

Winter weather puts real demands on storage facilities. Heavy snow, freezing temperatures, and unpredictable storms can stress roofs, structures, and long-term performance. For operators in snowy climates, strong engineering isn’t optional—it’s essential. That’s why Boxwell designs both relocatable self-storage units and portable storage units to perform reliably in winter conditions.

How much snow is too much for your storage units? With Boxwell, that question is already answered. Every unit is engineered for winter from the very start.

How Snow Load Works  

Snow load refers to how much weight a roof can safely support. Higher numbers mean stronger roofs built to carry more snowfall during storms. Boxwell roofs are engineered with a snow load capability that can support several feet of heavy, wet snow, even during the biggest winter events. For reference, that’s what you’d see in major storms across northern regions and high elevation climates.  

For those who like the technical side, our units are engineered to a 60 PSF snow load, which aligns with structural requirements commonly used for permanent buildings in cold-weather states. This level of engineering protects your site from winter stress and gives operators peace of mind through long seasons of heavy accumulation.  

Winter Ready by Design  

Boxwells are built from high-grade steel designed for long-term outdoor performance. Several features support winter strength and durability, including:  

• 4.0mm corrugated steel roofing – for structural rigidity 

• Stainless steel hardware – will not rust 

• Anti-condensation spray – helps manage interior humidity 

• Marine-grade flooring – stays strong, even in fluctuating temperatures 

These details work together to keep your units weather resistant, secure, and dependable year-round.  

Whether you’re expanding your portable storage fleet or adding relocatable units to your self-storage site, Boxwells performs the same way in winter as they do in summer.  

Myth Busting: Portable and Relocatable Units in Snow  

Myth #1: Portable containers cannot handle heavy snowfall.  

Some portable containers on the market use lightweight materials or fiberglass materials that may crack under pressure or extreme temperature changes. Boxwell’s portable storage containers are built different. They are engineered with the same snow load strength as our relocatable units and built for long-term, all-season outdoor use. You get dependable units that hold up when snow starts to pile up.  

Myth #2: Relocatable units are not as strong as permanent buildings.  

This is a common misconception. Boxwell relocatable units use corrugated steel roofing supported by reinforced framing. This gives them the structural performance needed for winter climates while still offering the flexibility of relocatable design, fast installation, and no foundation requirements.  

Installation Without the Seasonal Slowdown  

Winter weather does not stop our team! Boxwell’s install crews work year-round and are experienced with projects in cold, snowy, and fast changing conditions. Our installation process is efficient and reliable, which helps operators stay on schedule even when winter arrives early. Minimal downtime means your project keeps moving, no matter the forecast. 

Smart Choice for Snowy Climates 

If you operate in a region with heavy snowfall, snow load should be one of the first factors you consider when choosing storage units. Boxwells combine high strength engineering, weather resistant design, and proven winter durability. The result is a long-lasting solution that protects your investment and keeps customers confident that their belongings stay secure all season.
