Cable Tray Joint Plate
A cable tray joint plate is an important part of any cable tray system. It connects two trays together and ensures a strong joint. These plates are used in industries, commercial buildings, and large projects. They help in keeping the trays aligned and safe. A reliable manufacturer always focuses on quality because joint plates carry heavy loads of wires and cables. The right installation also matters because poor fitting can cause loose connections or safety risks. In this article, you will learn about cable tray joint plate manufacturing, its types, installation steps, and benefits. This will help you choose the best option for your project and understand how to fix it properly.
What is a Cable Tray Joint Plate?
A cable tray joint plate is a flat metal piece used to join two cable trays. It comes with drilled holes for nuts and bolts. The main job of the plate is to hold trays in place and provide stability. Without a joint plate, trays may shift or bend. This can lead to damage to cables.
Importance of Using Joint Plates
Joint plates keep trays aligned.
They increase the strength of the cable tray system.
They make the installation secure and safe.
They allow trays to carry heavy wires without bending.
Materials Used in Manufacturing
Most joint plates are made from strong metals. Common materials include:
-
Mild Steel (MS) – Affordable and strong.
-
Stainless Steel (SS) – Rust-free and long-lasting.
-
Aluminum – Lightweight but durable.
Manufacturers also apply surface coatings like hot-dip galvanizing, powder coating, or zinc plating. These coatings protect the plate from rust and increase life span.
Types of Cable Tray Joint Plates
There are different types of joint plates used for cable trays. The choice depends on the design of the tray.
-
Straight Joint Plate – Connects trays in a straight line.
-
L-Type Joint Plate – Used for 90-degree turns.
-
T-Type Joint Plate – Connects three trays in a T-shape.
-
Cross Joint Plate – Used when four trays meet at one point.
Features of a Good Manufacturer
When choosing a manufacturer, you must check a few qualities:
-
Use of high-quality raw materials.
-
Proper cutting, drilling, and finishing.
-
Strong coatings for anti-rust protection.
-
Affordable pricing with bulk supply.
-
On-time delivery.
A reliable manufacturer also provides technical support for installation.
