Square Frame 2 Sided Rolltainer Description:

What Is a Square Frame 2-Sided Rolltainer

A Square Frame 2-Sided Rolltainer is a heavy-duty mobile storage trolley designed with two upright mesh panels and an open front and back for easy access and high-speed loading. It features a square-tube welded base that provides stronger support and better durability than traditional A-frame or Z-frame bases. Ideal for logistics, warehousing, and retail distribution, it allows for smoother, safer, and more efficient internal material flow.

Structure & Materials

2-Sided Panels

The two upright panels are made from high-strength cold-drawn steel wire, welded into a tighter mesh configuration that prevents smaller items from falling out. The outer frame of each panel is formed from heavy-gauge round tubing, precision-bent to maintain rigidity while allowing removable. Each panel is hinged to fold inward for space-saving storage when not in use.

Square Base

At the heart of this rolltainer is a fully welded square-tube base, built with thicker wall tubing for improved weight-bearing capacity. The square design offers a flatter, more stable platform than other base types, making it better suited for transporting stacked cartons or uneven loads. The perimeter of the base is reinforced to reduce flexing under stress, prolonging service life.

Casters / Wheels

Mounted beneath the base are four industrial-grade casters—two fixed and two swivel. Each wheel is made with wear-resistant polyurethane or rubber tread, depending on your floor type. Double ball bearings provide smoother rotation and less resistance during handling. Optional configurations include total-lock brakes or directional locks for improved safety on slopes or during static loading.

Shelves & Accessories

Optional foldable or fixed shelves can be inserted to create multi-level storage within the cage, ideal for separating fragile or high-turnover goods. These shelves are typically bolted in or secured with spring clips, offering better load stability. Other accessories include nameplate holders, ID card slots, straps, lids, or even branding plates for easier warehouse tracking and product identification.

How BOHONGKE Produce a Square Frame 2 Sided Rolltainer

At BOHONGKE, every Square Frame 2-Sided Rolltainer is manufactured through a more precise, more controlled, and more efficient production process than what you'll find at ordinary facilities. By handling all stages in-house—from raw material preparation to final inspection—we guarantee higher consistency and better product performance.

1. Steel Tube & Wire Preparation

We begin with premium-grade Q235 or Q195 steel. Square tubes are cut and deburred using high-speed saws for sharper edges and more accurate lengths. Cold-drawn steel wires are straightened and pre-processed to ensure higher tensile strength and smoother weldability.

2. Frame Forming & Welding

The square base is fabricated using precision jigs to hold each tube in position. We use robotic welders and semi-automatic machines to ensure cleaner weld seams and stronger joints, especially at load-bearing corners. Side panels are formed by bending heavy-gauge round or square tubing into frame shapes, then welding the mesh grid securely inside.

This step is monitored with more stringent tolerance checks to ensure every panel nests smoothly and folds reliably during use.

3. Surface Treatment

Depending on the application, each unit undergoes one of the following surface finishes:

Electro-galvanizing:

for light-duty indoor use with clean aesthetics.

Hot-dip galvanizing:

 for tougher environments needing stronger corrosion protection.

Powder coating:

for color-customized finishes and added abrasion resistance.

All treatments are done in-house, giving us tighter control over coating thickness, adhesion, and environmental compliance.

4. Caster Installation & Assembly

Casters are mounted using reinforced steel plates and secured with bolts or rivets to prevent wobbling or detachment. We select casters based on floor type, load capacity, and usage conditions. Afterward, the side panels are attached to the base via hinge brackets, and optional shelves or accessories are installed according to order specifications.

5. Inspection & Load Testing

Before packaging, each rolltainer undergoes a 3-stage inspection:

Visual check:

for weld defects, paint uniformity, and hardware completeness.

Dimensional check:

for height, width, caster alignment, and shelf fit.

Load test:

with simulated weights to ensure the base holds firm and the structure doesn't deform.

Products that pass are labeled with unique batch codes for traceability.

6. Packaging & Shipping

Rolltainers are partially folded and nested to minimize shipping volume. Each stack is stretch-wrapped and banded to heavy-duty pallets, reducing freight damage. Detailed packing lists and QC reports are included for seamless customs clearance and warehouse receipt.

How to Use Square Frame 2 Sided Rolltainer

Using a Square Frame 2-Sided Rolltainer is straightforward, but when operated correctly, it performs with greater safety, speed, and efficiency than traditional trolleys. Whether you're moving bulk cartons, loose packages, or unstable loads, this rolltainer streamlines the process with fewer touchpoints and less handling time.

1. Preparation & Installtion

Insert the disassembled panel mount into the hole of the Base. The two upright mesh panels will lock securely into the square base frame. Make sure the casters are fully functional—unlock the brakes if they're engaged.

2. Loading the Trolley

Place goods centrally on the base to distribute weight evenly. Stack heavier items at the bottom and lighter ones on top to maintain a low center of gravity. If you're using optional shelves, adjust their height to separate SKUs or fragile goods.

Secure loose or unstable items with straps, clips, or protective corner guards—especially during long-distance movement or transport over ramps.

Best Practice:

Don't exceed the designed load capacity—BOHONGKE rolltainers can handle more weight than typical models, but overloading can still shorten lifespan.

3. Moving & Maneuvering

Push the rolltainer using the ergonomic handle. Thanks to BOHONGKE's double-ball bearing swivel casters, steering is smoother—even when fully loaded. Always keep hands on both sides of the handle when navigating tight aisles.

Engage the brakes when stopping on slopes or loading docks. Use directional locks (if equipped) for improved control during long straight-line movement.

Important:

Avoid sudden turns or abrupt stops when fully loaded to prevent tipping.

4. Unloading & Sorting

Once at your destination, use the open front and back to quickly access and remove items. Because there are no front or rear panels blocking the load, you can unload in half the time compared to 4-sided cages.

For operations like picking or sorting, attach labels, barcode cards, or ID tags to the mesh for clearer tracking.

5. Disassembly & Storage

After use, remove the panel from the base plate. You can put the Panel on the base.

Maintenance Tip: Clean the casters regularly and inspect welds or hinges for signs of wear. Proper maintenance can extend the trolley's service life significantly.

When used correctly, a Square Frame 2-Sided Rolltainer not only improves operational flow but also reduces manual strain and product damage—making it an indispensable tool in fast-paced logistics environments.

How to Choose Square Frame 2 Sided Rolltainer and a Supplier In China

Choosing the right Square Frame 2-Sided Rolltainer—and the right Chinese supplier—can make a significant difference in your logistics efficiency, product lifespan, and total ownership cost. With dozens of manufacturers claiming to offer “quality,” it's crucial to go beyond surface-level specs and evaluate based on structure, material integrity, production capability, and after-sales reliability.

1. Choose the Right Rolltainer Based on Your Application

Load Type & Weight Capacity:

If your goods are bulky or heavy, choose a rolltainer with a thicker square-tube base (like BOHONGKE's 40×40 mm frame) and reinforced mesh panels. For lighter tasks like parcel sorting, lighter tubing may be acceptable.

Storage Efficiency Needs:

Look for nestable side panels and foldable options. BOHONGKE rolltainers nest more tightly due to the square chassis and hinge design—ideal when storage space is tight.

Caster Configuration:

Smooth floors? Use rubber or PU casters for quieter rolling. Need directional control? Choose options with lockable swivel wheels. Confirm if your supplier allows caster customization without high MOQs.

Surface Finish Based on Environment:

For dry indoor use, electro-galvanized finish is enough. In humid or outdoor settings, hot-dip galvanizing or powder coating is more durable. A good supplier will offer all three.

Optional Add-ons:

Does your operation need intermediate shelves, label holders, or locking lids? A flexible supplier like BOHONGKE offers tool-free add-ons that integrate seamlessly.

2. How to Evaluate a Chinese Supplier

Are They a Manufacturer or Trading Company?

Many trading companies outsource production. This reduces control over quality, delivery, and pricing. Always ask for factory audit photos, business licenses, or visit the facility virtually. BOHONGKE, for example, owns a 15,000m² factory and handles every stage in-house.

Do They Have Engineering & Customization Capabilities?

A serious factory will offer structural drawings, load calculations, and pre-production samples. If a supplier cannot adapt standard models for your needs, they likely lack internal tooling or welding resources.

What Quality Control Processes Are in Place?

Ask for details: How many QC stages? Do they perform load testing, caster inspection, weld seam checks? BOHONGKE implements multi-point inspections and batch traceability down to the raw steel supplier.

How Transparent Are Their Prices?

A trustworthy supplier will break down the pricing and explain cost differences—rather than offering only a vague “best price.” If price seems too low, it usually reflects cut corners in steel thickness, coating, or caster quality.

What Is Their After-Sales Commitment?

Will they send replacement parts? How fast do they respond to quality issues? BOHONGKE commits to 24-hour response and offers no-charge replacements for confirmed factory defects.

Can They Support Long-Term Growth?

If you're scaling operations, choose a supplier with the capacity to grow with you. BOHONGKE supports clients ranging from regional distributors to multinational retailers—offering consistent quality across thousands of units.

Final Tip:

Always start with a sample order and verify weld strength, caster smoothness, and overall handling feel. A well-built Square Frame 2-Sided Rolltainer should feel sturdier, roll more quietly, and load more evenly than cheaper, poorly assembled alternatives.

Choosing BOHONGKE means choosing a partner—not just a product. We don't just sell trolleys—we help you optimize your operations with more reliable, longer-lasting equipment made by people who understand what real logistics demand.
