How to Inspect a Shipping Container Before Purchase

Purchasing a shipping container can be a savvy investment for storage, construction, or customization projects. However, the key to making a wise purchase lies in a thorough inspection. Rust, dents, and faulty doors can turn a seemingly good deal sour. This article aims to guide you through the essential steps to inspect a shipping container before purchase, ensuring you know exactly what to look for to avoid hidden problems and secure a container that meets your needs.

Understanding Shipping Container Grades

When embarking on the journey of buying a shipping container, the first step is to decode the alphabet soup of container grades. These grades, ranging from new and pristine to well-worn and seasoned, play a pivotal role in determining the container's suitability for your project. Here's a quick breakdown:

Grade A: These containers are closest to the new condition. They may have been used for one trip or less and show minimal signs of wear. Ideal for projects requiring a clean, aesthetically pleasing appearance.

Grade B: A more cost-effective option, these containers have been used but are still in good condition. Expect minor dents and surface rust, but nothing that compromises the structure.

Grade C: With visible wear and tear, including dents, rust, and possibly repairs, these containers are functional but may require some TLC. They're a budget-friendly choice for storage or projects where appearance is less critical.

Understanding these grades helps you align your expectations and budget with the container's condition, ensuring you choose the right type for your specific needs.

Preparing for the Inspection

Before you dive into inspecting a shipping container, a little preparation goes a long way. Equipping yourself with a few basic tools can help you conduct a more thorough inspection. Here’s what you should bring along:

Flashlight: For peering into dark corners and under the container to check for holes or rust.

Gloves: Protect your hands from sharp edges and rust.

Measuring Tape: To verify dimensions and ensure the container meets your space requirements.

Camera: To document any issues you may need to discuss or negotiate with the seller.

Timing is also key. Try to schedule your inspection during daylight hours to take advantage of natural light, which will make it easier to spot potential issues. Remember, the goal of the inspection is to uncover any hidden problems that could affect the container's functionality or your project's success. With the right tools and timing, you’re set to assess the container's condition accurately.

Structural Integrity Checks

Inspecting the structural integrity of a shipping container is like playing detective - you're looking for clues that tell a story of the container's past and its fitness for your future plans. Here's how to go about it:

Roof Inspection: Start your investigation at the top. The roof bears the brunt of heavy loads and weather, so check for any sagging that suggests structural weakness. Use your flashlight to spot rust patches, significant dents, or holes, particularly at the corners where water tends to pool and cause damage. These flaws can compromise the container's integrity and lead to leaks.

Wall Inspection: The walls of a shipping container should stand tall and proud. Run your hands along them, feeling for indentations. Your flashlight will come in handy here to highlight any corrosion or impact damage. Beware of bulges or bends, as they indicate the container may have been overloaded or hit.

Floor Inspection: The floor takes a beating from the inside. In containers with wooden flooring, probe for signs of rot or pest infestation, which can undermine the structural and health safety of the container. Metal floors should be checked for rust or corrosion, especially along the seams.

Door Functionality and Security

Doors are the gateway to your container's usability, so their functionality is non-negotiable. Here's what to focus on:

Ease of Operation: Open and close the doors several times. They should move smoothly without resistance. Any sticking or difficulty in operation could signal alignment issues, which are not only a hassle but could also compromise security.

Seals and Gaskets: Examine the rubber seals around the door edges. These are crucial for making the container weatherproof. Cracks or brittleness in the seals can lead to water ingress, damaging the contents. Ensure the gaskets are intact and replaceable.

Locking Mechanisms: Security is paramount, so give the locking mechanism a thorough check. Ensure it operates smoothly and doesn't show signs of tampering or wear that could make it easy to break into.

A container might pass the eye test, but the true measure of its condition lies in these structural and functional details. By conducting a meticulous inspection of the roof, walls, floor, and doors, you're not just assessing a container's current state; you're also gauging its longevity and reliability for your project.

Identifying Common Issues

When inspecting a shipping container, keep an eye out for:

Rust and Corrosion: Look for extensive rusting that could compromise the container's structure. Surface rust is manageable, but deep rust indicates serious decay.

Dents and Deformations: Minor dents are typical, but significant deformations can affect the container's usability and integrity. Ensure the container stands straight and level.

Other Red Flags: Beware of strong chemical odors or stains, suggesting hazardous materials were previously stored inside. Missing or illegible identification codes can also be problematic for tracking and verification purposes.

The Value of Professional Inspection

Even if you feel confident in your inspection skills, a professional inspection can uncover hidden issues and ensure the container meets all necessary standards:

Professional Insight: A certified inspector can provide a detailed assessment of the container's condition, highlighting any concerns and verifying structural integrity.

Certification Check: For shipping purposes, containers must have a valid CSC (Container Safety Convention) plate. A professional can confirm this certification or guide you on getting the container certified, ensuring it's fit for international transport.

A detailed self-check combined with a professional inspection ensures you make an informed decision, securing a container that meets your needs and complies with all required standards.

Conclusion

Concluding, the key to successfully purchasing a shipping container lies in meticulous inspection and understanding what to look out for. By keeping an eye on rust, dents, and ensuring the doors work properly, you can avoid common pitfalls. Don't underestimate the value of a professional inspection to confirm your findings and ensure the container is up to standard. This process ensures you invest wisely, securing a container that meets your needs and stands the test of time.
