OOG FLAT RACK Lashing ✓

Open top containers have an open roof that is covered with a tarpaulin. They are used for machinery, marble blocks, glass, steel and long materials that need to be crane-loaded from above or exceed the container door height. Over-height cargo can be shipped with the tarpaulin properly secured.

Flat rack containers are platform-type units with no side walls or roof and with collapsible front and rear end walls. They are preferred for out-of-gauge cargo whose width or height exceeds container dimensions, such as construction machinery, transformers, tanks, boats and steel structures. Loading can be done from the side or from above.

In special equipment container operations, success depends on limited equipment availability, shipping line approval, out-of-gauge charges and the securing plan. Wislog Lojistik manages equipment sourcing, lashing at the loading point, port and vessel planning, and discharge coordination at destination from a single point.

Frequently asked questions

What are the dimensions of an open top container?

A 20’ open top container has internal dimensions of approximately 5.9 m in length, 2.35 m in width and 2.35 m in height; a 40’ open top offers an internal length of about 12 m. As the roof is open, cargo can exceed the container height to a certain extent.

How much cargo can be loaded onto a flat rack container?

Although it varies by equipment type, a 20’ flat rack can offer a payload of approximately 30 tonnes and a 40’ flat rack approximately 40 tonnes. The exact capacity depends on the technical specifications of the equipment used.

Are OOG (out-of-gauge) shipments subject to additional charges?

Yes. Because out-of-gauge cargo takes up extra space on board, shipping lines generally apply additional freight and equipment charges. Charges are calculated based on the amount of overhang and the route.

For every transport mode and cargo type, we have summarised our processes, the benefits and the key points to consider.

Transport Modes

International Sea Freight

Sea freight is the most economical option for high-volume, long-distance cargo. We manage the entire process — from freight booking and port operations to container tracking and delivery at the port of destination. Our strong line connections support Far East imports and Mediterranean–Gulf exports.

FCL and LCL Container Shipping

If your cargo fills a container, FCL gives you a container dedicated solely to your shipment; for smaller volumes, LCL means you pay only for the space you use. We move your full and part container loads from Far East ports and Europe on regular sailings.

International Road Freight

Road freight is the most flexible way to deliver door to door. We run regular shipments to Poland, Germany, the Netherlands, Belgium, France, Italy, Bulgaria, Greece, Albania and the Baltic states, carrying your cargo safely with curtainsider, mega trailer and ADR-equipped vehicle options.

Full Truckload and Groupage Trucking

If your cargo fills a truck, we offer fast, direct full truckload transport with no transhipment; for loads of just a few pallets, we provide a cost-effective part load solution. We run regular shipments on routes to Poland, Latvia, Lithuania, Germany, the Netherlands, Belgium, Bulgaria, Greece, Italy, France and Albania.

International Air Freight

For urgent production parts and high-value goods, air freight turns time into an advantage. We organise your exports departing from Istanbul and Sabiha Gökçen airports, as well as your imports from around the world, in line with IATA rules.

Domestic Road Transport in Türkiye

We provide full truckload and part load road transport across Türkiye, connecting factories, warehouses, ports and bonded warehouses. We manage the movement of your export cargo to the port and your import cargo from the port to your warehouse, fully integrated with your international operations.

Cross-Trade (Third-Country) Shipping

Goods you buy in the Far East, Europe or the Americas can be shipped straight to Libya, Lebanon, Dubai, Saudi Arabia, Morocco, Italy or France without a detour through Türkiye. We manage freight, documentation and customs coordination from a single desk and protect commercial confidentiality between your supplier and your buyer.

Specialist Cargo

Chemical and Dangerous Goods Transport

We specialise in hazardous cargo such as chemical raw materials, aerosols, flammable liquids and corrosive products. With correct classification, packaging, labelling, documentation and equipment, we deliver fully compliant transport by road, sea and air.

Cosmetics, Deodorant and Detergent Transport

Aerosol products such as deodorants and perfumes, cosmetics and personal care products, and liquid and powder detergents all need specific planning — both because of dangerous goods rules and because they are easily damaged. We bring experience of regular shipments in these product groups to European, Middle Eastern and African markets.

Raw Material Transport

Keeping your production line running depends on raw materials reaching your factory at the right time. From plastic granules to chemical raw materials, and from minerals and fillers to packaging materials, we manage your raw material imports and exports by sea and road in a planned way.

Furniture Transport

We carry Türkiye’s strong furniture exports to European, Middle Eastern and African markets. For bulky, fragile furniture with delicate surfaces, we aim for damage-free delivery through the right vehicle, careful stowage and protective packaging.

Machinery and Project Cargo Transport

Production lines, CNC machines, generators, steel structures and out-of-gauge equipment require route surveys, special equipment and lifting plans. We plan your machinery and project cargo from loading after dismantling through to delivery on site.

Warehousing & Bonded Storage

Warehousing Services

By combining transport with warehousing, we make your supply chain more flexible. In warehouses in Türkiye and, through our partners, around the world, we provide short- and long-term storage, handling, palletising, labelling and shipment preparation services.

Bonded Warehouse and Customs Storage Services

You can hold imported goods in a bonded warehouse without paying customs duties and fees, release them for free circulation in partial quantities as needed, or re-export them. We manage your bonded warehouse processes together with transport and customs coordination.

Cargo Collection and Consolidation Services

We bring together the products you buy from multiple suppliers — in different countries or within the same country — at collection warehouses, inspect them and combine them into a single container or truck shipment. This lowers your freight costs and reduces your documentation and tracking workload.
