Kales High-End Logistics DivisionWhat is a Curtainsider (Tautliner) Trailer?
A curtainsider semi-trailer (or tautliner) is an advanced logistics vehicle that combines the fast, unobstructed side-loading capability of a flatbed with the weather-proof protection of a dry van. Featuring sliding PVC curtains, aluminum roof structures, and a T700 high-strength chassis, the Kales curtainsider is the gold standard for transporting palletized FMCG, beverages, and automotive parts rapidly.
Aerodynamic chamfered corners to reduce wind resistance and save fuel.

In the fast-paced world of FMCG, Beverage, and Automotive logistics, time is money. Traditional dry vans limit you to rear-door loading, creating severe bottlenecks at the dock. The Kales Curtainsider changes the game:
- 🚀 Side Loading Efficiency: The heavy-duty PVC curtains slide open completely, revealing the entire 13-meter deck. Forklifts can load pallets from both sides simultaneously, reducing loading time from 1 hour to just 20 minutes.
- 📦 Versatile Cargo Handling: Unlike fixed-wall dry vans, the tautliner can easily accommodate oversized width cargo, long steel pipes, or heavy machinery that simply cannot fit through a rear door.
- 🛡️ Cargo Security: The internal structure features movable pillars and horizontal side planks, allowing operators to secure cargo tightly with straps, preventing shifting and damage during transit.
Quick-Release Tensioner System for Fast Access 🌍 Field Record: FMCG Fleet Efficiency
“We distribute beverages and palletized groceries across cross-border routes. Switching from dry vans to Kales 13M Curtainsiders revolutionized our turnaround times. Since multiple forklifts can access the side deck simultaneously, our dock loading time dropped by 60%. The T700 chassis easily handles the 45-ton payloads, and the PVC curtains keep the cargo 100% dry during monsoon seasons.”

2. Premium Chassis & Manufacturing Technology
A trailer is only as good as its backbone. Kales utilizes advanced manufacturing processes to ensure extreme longevity and lower tare weight:
💎 T700 High Strength Steel
We upgraded the main beam material from standard Q345 to T700 High Strength Steel. This drastically reduces the trailer’s tare weight while safely increasing the payload capacity to 40-50 tons without any risk of chassis deformation.
🎨 Polyurethane Paint System
Before painting, the chassis undergoes deep Shot Blasting to remove all rust and stress. We then apply a premium Polyurethane Paint system (2 primers + 2 topcoats), guaranteeing 5+ years of rust resistance even in highly corrosive coastal environments.
🔗 Aluminum Alloy Structure
To further maximize payload efficiency and reduce dead weight, the roof support framework, side rails, and heavy-duty toolboxes are forged from Aluminum Alloy. This directly lowers fuel consumption for the tractor head.
3. Global High-End Configuration Options
Kales partners with the world’s best component manufacturers to ensure your fleet stays on the road, not in the repair shop.

Is the curtain secure against cargo theft?
The standard 900gsm PVC curtain is exceptionally tough and designed for heavy weather protection. However, for high-value cargo routes, we offer an optional “Anti-Slash Mesh” reinforcement embedded directly inside the curtain to prevent cutting and theft. Additionally, the rear doors are solid steel or aluminum with robust container-style locking bars.
How durable is the sliding curtain mechanism?
The curtain rollers, top tracks, and quick-release tensioners are industrial-grade components designed to withstand tens of thousands of opening cycles. With simple routine cleaning and light lubrication of the aluminum tracks, the entire mechanism will operate smoothly for years without jamming.
Can I customize the trailer’s length and height?
Yes. While 13.75m is the global standard length, we frequently build 15m or 16m super-long versions for clients looking to maximize cubic meter (CBM) volume. We can also adjust the internal height up to 3 meters, strictly depending on your local highway and bridge clearance regulations.
What is the manufacturing and delivery time?
Due to the highly customized nature of curtainsiders (including specific axle choices and curtain branding), production typically takes 20-25 working days after receiving the deposit. We strongly recommend ordering in advance to synchronize with international Ro-Ro or Bulk Cargo shipping schedules.

Frequently Asked Questions
Can you customize the trailer design according to my requirements?
Yes, absolutely. As a manufacturer, we have a professional engineering team. We can customize the dimensions, loading capacity (e.g., 60 tons, 80 tons), axle brand (FUWA/BPW), suspension type, and paint color to suit your specific road conditions and transport needs.
What material do you use for the main beam?
We use high-strength Q355 or T700 steel for the main beam. This ensures the trailer is lightweight yet strong enough to withstand heavy loads and rough road conditions in Africa and Central Asia.
What is your production time?
Standard models usually take 15-20 working days after receiving the deposit. For urgent orders, we can even shorten it to 10 days. We will keep you updated with photos and videos during production.
What are your payment terms?
Our standard term is T/T (30% deposit, 70% balance before shipping). For large orders, L/C (Letter of Credit) is also negotiable.
Do you provide a warranty?
Yes, we provide a 24-month warranty for the main beam. For spare parts (like brake pads, lights), we supply original parts at factory cost for the lifetime of the trailer.
Flexible Logistics Solutions: Safe & Cost-Effective Delivery
