About products and suppliers

A metal clamp is a device used to hold two or more objects together, typically by applying pressure to prevent them from moving or separating. Metal clamps are commonly used in woodworking, metalworking, architecture, and other industries.

Types and usages of metal clamps

Lifting clamps for steel are designed to firmly grip and lift steel plates, sheets, or other steel structures. They are commonly used in conjunction with cranes or other lifting equipment. There are several types of lifting clamps for steel. Vertical plate clamp is designed to lift and transport steel plates in a vertical direction. It typically has a pivoting cam that engages the steel plate when pressure is applied. The horizontal plate clamp is similar to the vertical plate clamp but the horizontal plate clamp is used for lifting steel plates in a horizontal orientation. It is suitable for lifting plates that need to be positioned horizontally.

Sheet metal clamps or sheet metal lifting clamps are designed to securely hold and position thin sheets of metal during various working processes such as welding, cutting, forming, and assembly. Sheet metal clamps are used to prevent the metal sheets from shifting or deforming during these operations, which can ensure precision and accuracy in the work. Sheet metal clamps usually have jaws that are designed to tightly grip the edges of the sheet metal. The jaws may have serrations to enhance the strength of the grip. Some sheet metal clamps can be quickly released and rapidly adjusted. These features can be especially useful when working on multiple sheets or when the sheets need to be frequently positioned again.

Tips on using metal clamps

Select a metal clamp of an appropriate size and material for the specific task and material that is to be processed. For example, small metal clamps are used for tasks that need special accuracy and precision. Aluminum clamps, though lightweight, are known for their strength, and they also have resistance to corrosion, which makes them an ideal choice for many important tasks. Before using metal clamps, check the metal clamps for any signs of damage or wear and whether it is bent, and make sure the moving parts of the metal clamps operate smoothly. Damaged metal clamps should be repaired or replaced.

Keep metal clamps clean. Lubricate moving parts regularly to ensure that they can operate normally. This procedure is especially important for metal clamps with screws, hinges, or other adjustable mechanisms. Ensure that the metal clamp is positioned correctly for the task, and the jaws should be close to the working materials in the appropriate place. Avoid tightening a clamp excessively, which can lead to damage to some delicate materials. When the task is finished, release the metal clamps carefully and avoid sudden releases that can cause the working materials to move unexpectedly.
