Why Steel Structure & Sandwich Panel Loading Requires Specialized Expertise

Quick answer: safe loading of steel structures and sandwich panels depends on inspection, accurate measurement, loading planning, surface protection, proper stacking and secure fixing inside the container. If you want to evaluate packing quality or compare panel options before shipment, see our inspection guide, product page and sandwich panel comparison guide.

• Long and heavy components: H-beams, columns and purlins can be up to 12 meters long and weigh several tons each
• Easily damaged surfaces: Color steel sheets and sandwich panel surfaces are prone to scratches and dents
• Irregular shapes: Different components have different sizes and shapes, making space planning difficult
• High value: A single 40-foot container can carry steel structure materials worth tens of thousands of dollars

You could lose thousands of dollars and experience several months of delays on your project due to a single mishap in the loading process. This is the reason we have made significant investments in developing and perfecting our professional loading process.

Our 7-Step Professional Container Loading Process

Step 1: Pre-Production Quality Inspection & Measurement

Before any product leaves our factory, we conduct a comprehensive quality inspection and precise measurement of every component.

• We verify that all steel structure components and sandwich panels meet your exact specifications
• We measure the exact dimensions and weight of each item to create an accurate loading plan
• We identify any oversized or overweight items that require special handling
• We check for any surface defects or damage that may have occurred during production

This step ensures that only high-quality products are loaded into the container, and that we have all the information we need to create an optimal loading plan.

Step 2: Customized 3D Loading Plan Design

Our logistics team comes up with a clear 3D loading plan for each order using the measurements from Step.

• We use specialized software to calculate the exact placement of each item in the container
• We maximize space utilization by fitting components together like puzzle pieces
• We distribute weight evenly throughout the container to comply with international shipping regulations
• We plan the loading order to ensure easy unloading at your site

Optimized loading plans would typically allow us to store approximately 15 to 20% more product in the same volume of container when compared to the traditional loading process, thereby reducing your freight expense.

Step 3: Product-Specific Packaging & Protection

Different products require different packaging and protection measures. We have developed customized packaging solutions for all our products:

• Sandwich panels: Each panel is wrapped in protective film, with extra thick foam padding on the corners and edges
• Steel beams and columns: Wrapped in waterproof plastic film to prevent rust during shipping
• Small components and hardware: Packed in labeled wooden crates to prevent loss
• Glass and other fragile items: Packed in shock-absorbent foam and wooden crates

All packaging materials are moisture-resistant and suitable for long ocean voyages.

Step 4: Container Inspection & Preparation

Before loading starts, we check the container carefully. We want to make sure it’s in good shape.

• We check for any holes, leaks or structural damage in the container
• We clean the container floor to remove any dirt, debris or sharp objects
• We lay down wooden pallets on the floor to protect the bottom layer of products from moisture
• We install protective padding on the container walls to prevent scratches

This step makes sure that your container won’t harm your cargo while shipping.

Step 5: Layered Loading According to Plan

We put the container exactly the way we designed it with the 3D loading plan in Step 2 on the basis of the general rule of “ put the heavy things at the bottom and the light things at the top”.

• First, we load the heaviest items such as steel columns and main beams
• Next, we load medium-weight items such as purlins and secondary beams
• Finally, we load the lightest and most fragile items such as sandwich panels and accessories
• We leave appropriate gaps between items to allow for air circulation and prevent friction damage

We made our reinforcement methods tough enough for all that rough handling and wild movements during ocean shipping.

————————————————————————

Step 6: Comprehensive Reinforcement & Securing

Critical step for cargo damage prevention is during shipping. Multiple reinforcements provide you with the assurance that the item will not move during the transit process.

• We use heavy-duty steel straps to secure all large components to the container floor and walls
• We use wooden blocks and braces to fill any gaps and prevent items from shifting
• We use foam padding between layers to prevent scratches and dents
• We install additional cross-bracing for long components to prevent bending and deformation

We create reinforcement methods that can handle tough conditions and wild movements found in ocean shipping.

————————————————————————

Step 7: Final Inspection, Sealing & Documentation

After loading is complete, we conduct a final inspection of the entire container.

• We check that all items are properly secured and protected
• We take detailed photos of every layer and the final loaded container
• We seal the container with a tamper-proof seal and record the seal number
• We prepare all necessary shipping documents, including the packing list, commercial invoice and bill of lading

We provide you with photos and other documents directly from the load site so that you can feel confident while following the shipping process.

Custom Loading Solutions for Our Most Popular Products

For Sandwich Panels

Sandwich panels require special care during loading to protect their delicate surfaces and insulation cores.

• We load panels vertically on special racks to prevent bending and crushing
• We use foam separators between each panel to prevent surface scratches
• We add extra reinforcement around the edges to prevent chipping and damage
• We never stack heavy items on top of sandwich panels

For Prefabricated Steel Structure Factory Buildings

For steel structure factory building projects, we arrange loading in the opposite order of how things get set up.

• We load the items that will be installed first last, so they are the first to be unloaded
• We label all components clearly with installation numbers
• We pack all hardware and small parts in separate labeled crates
• We include a detailed installation guide and packing list with every shipment

The 3 Most Common Shipping Damages And How We Prevent Them

1. Sandwich panel surface scratches: Prevented by protective film wrapping and foam separators
2. Steel beam bending: Prevented by proper support and cross-bracing
3. Small parts loss: Prevented by sealed wooden crates and detailed packing lists

Because we use a 7-step loading system, less than a half percent of our shipments are ever damaged, whereas the rest of the industry averages 5-10%.
