Built for the Rain: How Our Parcel Boxes Keep Your Mail&Parcels Dry

When Rain Ruins More Than Your Mood

Imagine this: a friend sends you a heartfelt holiday card. You open your parcel box, excited—only to find soggy paper, smudged ink, and a ruined surprise. Sound familiar?

Rain is no friend to mail. But our parcel boxes are designed to make sure water stays out—no matter the weather.

The Problem: Water Sneaks In Through the Cracks
Most outdoor parcel boxes are made of metal panels joined together. But where there are joints, there are gaps—and where there are gaps, water finds its way in. Whether it's a drizzle or a downpour, traditional designs often leave letters and packages vulnerable.

We set out to change that.

Our Waterproof Engineering: Small Details, Big Results
We completely rethought how our parcel boxes manage water. Here’s what we added:

Angled Metal Rain Guards
At the mail slot and storage compartment, we introduced precision-folded metal rain lips that block water from streaming directly into the box.

Sealing Gaskets
Rubber weatherstrips line the edges where doors meet the box. These gaskets close the microscopic gaps that water can seep through, ensuring a tight, weather-resistant seal.

The Entry Points: Tested and Improved

We examined the two most common types of mail slots:

Push-to-open metal flap

Lift-up metal flap

Both were subjected to simulated torrential rain testing to observe how well they repel water under realistic conditions.

Test Results: Dry Mail, Happy Customers
Each entry type was tested under controlled water exposure, and we analyzed the results using a combination of visuals and inspection criteria.

What we found was clear:
Our redesigned rain guards and gasket system dramatically reduce water intrusion—even during extended exposure. Your mail stays dry. Period.

Final Takeaway
Rain happens. But it shouldn’t ruin your deliveries. With upgraded waterproof barriers and intelligent design, our parcel boxes do more than store your mail — they protect it.

Because your letters, cards, and packages deserve to arrive exactly the way they were sent.
