Steel Seals: A Key Component for Cargo Safety and Transportation

Steel seals are usually made of steel and are used to secure and close steel straps (or other types of strapping) to maintain the stability of the cargo. These seals pressurize and lock the steel straps, making the entire package more sturdy and reliable. They are widely used in the bundling and transportation of various industrial products, building materials, machinery and equipment, steel, and other bulk commodities.

Main Types of Steel Seals
There are many types of steel seals to meet different bundling and packaging needs. Common types include:

Traditional Metal Seals
This seal uses high-strength metal materials to compress and lock the steel straps, which is suitable for heavy-duty bundling and provides maximum security.

Aluminum Seals
Aluminum seals are lighter in weight, but still strong enough to suit the bundling of light and medium-duty cargo. They are corrosion-resistant and suitable for use in wet or harsh environments.

Double Ear Seals
Double Ear Seals are designed to lock with two different ear-shaped structures, which can quickly and firmly close the strapping without the need for additional tools.

Single Ear Seals
Single Ear Seals are simpler than double ear seals, suitable for small and medium-sized goods, and provide efficient sealing functions.

Application areas of steel belt seals
Steel belt seals are widely used in various industries, especially in logistics transportation that requires heavy bundling, playing a vital role.

Steel and metal industry
Steel products such as steel pipes, steel coils, metal sheets, etc. need to be bundled with steel belt seals to ensure that they are not displaced or damaged during transportation.

Construction industry
Heavy building materials such as cement, bricks and sand and gravel often need to be bundled with steel belts, and steel belt seals provide security for fixing these items.

Wood and paper industry
During the transportation of fragile items such as wood, cartons, and wooden boards, steel belt seals also play a role in preventing damage to items and ensuring transportation safety.

International Trade and Cargo Container Transport
As global trade increases, steel seals have become a standard feature in container transport, ensuring the safety of goods during long-distance transport.
