It plays a vital role in various applications, making it an essential component in construction, manufacturing, and everyday life. This article will help you to get a clear idea about the type, buying guide, and the current price of Chain Kobja in Bangladesh.

Importance of Chain Kobja in Bangladesh

Supporting Diverse Industries: Chain Kobja finds applications in numerous sectors across Bangladesh, including:

Construction: Used for creating door frames, securing fixtures, and establishing temporary structures.

Manufacturing: Employed in assembling machinery parts, securing panels on enclosures, and establishing production line elements.

Furniture Making: Utilized for creating cabinet doors, folding tables, and other furniture with hinged components.

Home Improvement: Employed for hanging shelves, creating foldable workbenches, and establishing various DIY projects.

Affordability and Functionality: Chain Kobja offers a cost-effective and practical solution for various needs. It is readily available, easy to install, and provides a long-lasting hinge mechanism, making it a valuable tool for both professionals and individuals undertaking home improvement projects.

Durability and Strength: Typically crafted from galvanized steel, Chain Kobja offers superior resistance to rust and corrosion, ensuring its longevity in various environments. Additionally, its continuous link design provides exceptional strength and stability, allowing it to withstand significant pressure and stress.

Technical Specifications of Chain Kobja

While seemingly simple in design, Chain Kobja comes with various specifications to ensure its suitability for different applications. Here are some key aspects to consider:

Material: Primarily made from galvanized steel for durability and rust resistance. Stainless steel options might be available for specific applications requiring enhanced corrosion resistance.

Length: Chain Kobja is commonly sold by the meter, allowing for the purchase of the precise length required for your project.

Width: The width of the chain kobja refers to the distance between the two hinge leaves, and it influences the size of the gap created when the hinge is opened. Common widths include 1 inch (25.4 mm), 1.5 inches (38.1 mm), and 2 inches (50.8 mm).

Thickness: The thickness of the metal sheet used in the chain links determines the overall strength of the hinge. Thicker chains can support heavier loads but might be less flexible.

Finish: Chain Kobja is usually available in a galvanized finish for corrosion resistance or a blackened finish for a more aesthetic appeal.

Different Types of Chain Kobja in Bangladesh

Chain Kobja comes in various types to cater to specific needs and applications:

Long Link Chain Kobja: Features larger links and is suitable for heavy-duty applications like supporting large doors or securing heavy objects.

Short Link Chain Kobja: Offers smaller links and provides greater flexibility, making it ideal for applications requiring smooth operation and frequent opening and closing, like cabinets or jewelry boxes.

Double Loop Chain Kobja: Features two loops at each end, allowing for easy attachment to other objects. This type is commonly used for hanging applications like signs or shelves.

 Half-round Chain Kobja: Also known as a half-round piano hinge, this type has a rounded edge on one side, which creates a smoother appearance when the hinge is closed. It is often used for applications where aesthetics are important, such as furniture making.

Checklist for choosing the right Chain Kobja

Before purchasing Chain Kobja, consider these factors to ensure it meets your needs:

Intended purpose: Identify the specific application for the hinge (door hinge, cabinet hinge, etc.).

Required length: Measure the length needed for your project and purchase accordingly.

Width: Choose the width that aligns with the desired gap size when the hinge is open.

Thickness: Select the thickness that offers the necessary strength to support the weight and stress the hinge will be subjected to.

Material and finish: Select the appropriate material (galvanized steel is common) and finish (galvanized or blackened) based on your application and desired aesthetics.
