Metal roofing shear

Types of Metal Roofing Shears

Metal roofing shears are tools used to cut metal sheets for roofing and other construction projects. There are numerous kinds of shears that are part of the metal roofing shear family.

• Hand Shears for Metal:

Hand shears for metal are manually operated shears. These tools are small, lightweight, and easy to carry. They are used to make straight cuts and minor notches on metal sheets. Hand metal shears are not limited to cutting roofing sheets. They can be used to cut through many other kinds of metal sheets. When using hand shears, the operator places the metal sheet in between the shear blades and then manually pushes the tool down to make the cut.

• Power Shears for Metal:

Power shears, also known as electric shears, are shears that have been fitted with an electric driving motor to make cuts easier. While they can be similar in structure to hand shears, power shears are usually larger and bulkier due to the added components necessary to make them power driven. Power shears for metal can be used to make longer cuts with a lot less effort than manual shears. To use power shears, the operator needs to secure the metal sheet and then adjust the shear blade/s to the part of the sheet he wants to cut. Once it's adjusted, it's just a matter of pulling the trigger to activate the shears until the desired cut is achieved.

• Metal Nibbler:

A metal nibbler is a powered cutting tool used to cut through numerous types of metal, including galvanized steel and stainless steel. They are often used in the construction and sheet metal fabrication industries to cut roofing panels, flashing, gutters, and other components. Depending on the setup, metal nibblers can be incorporated into a punch press or as a handheld power tool. An air-powered nibbler is often preferred for roofing because it offers a cleaner cut with minimal burrs and less dust than electric nibblers.

Metal roofing shears can be further classified based on the design and specifications of the shear blade.

• Guillotine Shears:

With a stationary lower blade and a moving upper blade, guillotine shears operate in a similar way to standard hand shears. Metal shears are often referred to as guillotine shears when the blade shape is straight. They are quite common in the roofing shear family and are usually powered by hand crank or electric.

• Circular Shears:

This tool uses a circular blade to cut through roofing metal sheets. It is usually powered by electricity, but there are other variants that can be powered by air or hydraulics. Due to the fact that circular shear blades can only make straight cuts, they are often used in conjunction with other cutting tools that can make curved cuts.

Specifications and maintenance of metal roofing shear

Specifications

• Sizes: Shears for cutting roofing metals come in various sizes to accommodate different cutting capacities and metal thicknesses. Smaller, more portable models may have cutting beds that range from 1m to 2m, while industrial shear machines have more extensive cutting beds.
• Cutting Capacity: This measures the thickness and gauge of METAL the shear can cut. Roofing metal typically ranges in thickness from 0.3mm to 1.5mm. The shear chosen should be able to handle the job.
• Cutting Method: Metal shears use various methods to cut metal, such as rotary trimming, snips and shear blades. The cutting technique determines the quality of the cut and the level of precision.
• Power Source: Shears can be powered by electricity, hydraulics, or pneumatics. An electric metal shear typically has a motor power of 1.5kw and 3kw. Hydraulic metal shears probably have a higher motor power because hydraulics require more power to function.
• Weight: The weight of a metal shear indicates how heavy it is in kg. The shear can either be portable or not, depending on its dimensions and weight. Portable shears can be moved around.

Maintenance

• Cleaning: It is crucial to remove scrap metal and debris after each cut. In doing so, it prevents foreign objects from getting into the machine's parts and avoids any form of damage. Nevertheless, cleaning the blade after every use prevents clogging and corrosion. Regular cleaning of impacted areas prevents the shears from working inefficiently.
• Lubrication: Lubricating the moving parts of the metal shear is helpful in maintaining smooth operation and prolonging the machine's lifespan. Lubricating the machine reduces friction and abrasion-induced wear. It is essential to apply the right type of lubricant to specific parts of the shear machine.
• Periodic inspection: Carrying out inspections from time to time helps operators spot potential problems. It also aids in determining areas that need adjustments, repairs, or replacements. Inspect the blades and moving parts for any signs of damage, wear, or misalignment.
