Before you begin cutting, be sure to have the proper tools and safety equipment on hand. Tools commonly used to cut the edgings of corten steel include angle grinders, plasma cutters and metal saws. Angle grinders are versatile and can be used to cut and shape steel. Plasma cutters are suitable for more precise cutting, especially for thicker Corten steel sheets. Metal saws, such as hacksaws or reciprocating saws with suitable blades, can also be used for cutting. Safety equipment is essential. You will need a pair of heavy duty work gloves to protect your hands from sharp metal edgingsand sparks, safety goggles to protect your eyes from flying debris, and a dust mask is recommended to prevent inhalation of metal particles generated during the cutting process.
III. Preparation Before Cutting Garden Edging
Measuring and Marking Corten Steel Edging
Accurate measurement is the first step to successful cutting. Use a tape measure to determine the length and width of corten steel edging needed for your garden project. Mark the steel with a permanent marker or metal scribe. For straight cuts, use a straightedge to make sure the lines are straight. For curved outdoor corten edgings, use a flexible curve board or string to mark the desired shape. Check measurements and markings carefully to avoid mistakes, as incorrect cuts can waste material and affect the final result.
Securing Corten Steel Edging for Safe Cutting
Once the rusted steel edging has been measured and marked, it needs to be securely fastened. This prevents the steel from moving during the cutting process, resulting in an uneven or inaccurate cut. You can use a jig to secure the steel tightly to a table or other stable surface. If using a larger piece of COR-TEN, consider securing it in a bench vise. Make sure the steel edging is secured in a location that makes it easy to maneuver the cutting area.
Safety Precautions (Gloves, Goggles, Etc.)
Wear all necessary safety equipment before starting any cutting operation. Ensure that work gloves fit comfortably and provide adequate protection. Safety goggles should completely cover the eyes without any gaps for debris to enter. Check dust masks to ensure they fit properly over the nose and mouth. Familiarize yourself with the safety features of the cutting tools you are using, such as the emergency stop button on an angle grinder or the proper grounding method for a plasma cutter. Work in a well-ventilated area to minimize the risk of inhaling fumes or dust.
IV. Step-By-Step Cutting Corten Steel Lawn Edging Process
1. Using An Angle Grinder
Selecting the Appropriate Cutting Blade
When using an angle grinder to cut rusted steel lawn edging, it is important to choose the right cutting blade. For weather resistant steel, it is recommended to use diamond or abrasive cutting blades designed for metal cutting. The thickness and diameter of the cutting blade should match the thickness of the steel being cut. Thinner cutting blades may be better suited for thinner steel plates, while thicker, more robust blades are suitable for thicker materials. Make sure the cutting blade is properly installed on the angle grinder according to the manufacturer's instructions.
Cutting Along the Marked Line
Start the angle grinder and allow it to reach full speed before approaching the steel. Hold the angle grinder firmly with both hands so that the cutting blade is perpendicular to the marked line on the steel. Slowly and steadily move the angle grinder along the marked line, applying even pressure. Avoid pushing the angle grinder too hard as the cutting blade may overheat or break. If the cut is not straight, stop the angle grinder and adjust the position before continuing. It may take some practice to achieve a smooth, straight cut.
Sanding the EdgingsAfter Cutting
After cutting, garden edging wholesale may be rough and sharp. Use a wheel or file mounted on an angle grinder to sand the edges. Move the wheel or file along the edge in a gentle, consistent motion to remove any burrs or jagged edges. This not only makes the edge safer, but also improves the overall appearance of the cut steel.
Setting up the plasma cutter requires some technical knowledge. First, make sure the plasma cutter is properly connected to the power source and that all hoses and cables are in good condition. Adjust the power setting of the plasma cutter according to the thickness of the outdoor steel edging to be cut. Thicker steel requires a higher power setting. Connect the torch to the plasma cutter and install the proper consumables such as electrodes and nozzles.
Precision Cutting
Hold the plasma cutter's torch at a 90 degree angle to the surface of the weather resistant steel, close to the marked line. Press the trigger on the torch to start the plasma arc. Slowly move the torch along the marked line, maintaining a steady speed. The plasma arc will melt the steel and create a clean cut. Plasma cutters are known for their accuracy, but it still takes some practice to achieve the best results. Watch the cut during the cutting process to make sure it follows the marked line accurately.
Cleaning Up After Cutting
After cutting with a plasma cutter, the kerf metal edging may have some slag (molten metal residue). Remove the slag with a wire brush or chisel. There may also be slight oxidization on the edges. If desired, the edgingscan be sanded and cleaned with an angle grinder or sandpaper. This helps improve the appearance of the cut steel and prevents potential corrosion problems.
3. How to Use a Metal Saw
Selecting the Right Saw Blade
For metal saws, choosing the right blade is crucial. Fine tooth saw blades are suitable for cutting CORTEN metal edging. the number of teeth per inch (TPI) should be adapted to the thickness of the steel. For thinner steel, use a blade with a higher TPI for a smoother cut. For thicker steel, a saw blade with fewer teeth but stronger construction is needed. Make sure the blade is properly installed on the saw according to the manufacturer's instructions.
Slow and Steady Cutting
Clamp the CORTEN Steel securely to the workbench. Start the metal saw and allow it to reach a steady operating speed. Slowly lower the saw blade onto the steel and cut along the marked line. Apply gentle, consistent pressure while cutting. Cutting too fast will cause the saw blade to overheat and may roughen the cut surface. If the saw blade begins to jam or cut unevenly, stop the saw and check the position of the blade and steel.
Finishing
After the cutting is complete, METAL EDGING may have some small burrs. Sand the metal edgingswith a file or sandpaper. A deburring tool can also be used to clean up the edges more effectively. This final step will give the cut steel a smoother appearance.
It is very important to clean the cutting edge thoroughly after cutting. Use a wire brush to remove any rust, chips or slag that may have accumulated during the cutting process. For more stubborn residues, solvents or metal cleaners can be used. Cleaning the edgings not only improves the appearance of the steel, but also helps prevent corrosion from occurring. A clean surface is also more conducive to the application of any protective coatings or installation into the garden.
Apply Protective Coatings Where Necessary
Although corten steel lawn edging will naturally develop a protective oxide film over time, there are certain situations where applying an additional protective coating may be beneficial. This is especially true if the steel will be exposed to particularly harsh environmental conditions, or if you want to enhance its appearance. There are a variety of coatings available, such as clear varnishes, waxes, or specialized antirust paints. Always follow the manufacturer's instructions carefully when applying a coating. Ensure that the steel surface is clean and dry before applying the coating for optimum adhesion.
Installing WeatherSteel Edging in the Garden
After the cutlawn edging has been cleaned and the coating has been applied if needed, it is time to install corten steel lawn edging in the garden. Dig a shallow trench in the area where the edging is to be installed. Place the steel edge into the trench, making sure it is level and straight. Stakes or other fasteners can be used to secure the edge in place. Backfill the trench with dirt, compacting the dirt tightly around the steel edge to keep it in place. The installation process should be done carefully to ensure that the edge looks neat and functions properly.
To prevent excessive rusting and weathering, avoid placing outdoor steel edging in areas that are frequently wet or exposed to standing water. If possible, provide drainage around the edge. Clean steel surfaces regularly to remove dirt, leaves and other debris that can accumulate moisture and accelerate the rusting process. If you notice any signs of uneven or excessive rusting, gently scrub the area with a wire brush and apply a rust inhibitor if necessary.
Regular Cleaning and Inspection
Get into the habit of cleaning OUTDOOR STEEL EDGING on a regular basis. This can be done with a simple garden hose and a mild detergent. Check the edgings for any signs of damage, such as cracks or loose parts. If you find any problems, deal with them promptly. For example, if a part of the edging is loose, refasten it using the appropriate fasteners. Regular maintenance helps to keep the edge looking good and functioning properly for many years.
Long-Term Durability Maintenance
Over time, the oxide film on corten steel will continue to develop and change. While this is a natural process, steps can be taken to control it if you want to maintain a particular appearance. Avoid using strong chemical or abrasive cleaners that may damage the oxide film. If you want to slow down the formation of oxide film in specific areas, you can apply a clear protective coating. Keep in mind, though, that this may also affect the natural aging process of the steel. By following these long-term maintenance tips, you can ensure the durability and aesthetics of your outdoor corten steel edging.
VII. Common Mistakes to Avoid When Cutting Garden Corten Edging
Using the Wrong Tool
One of the most common mistakes is using the wrong tool for cutting metal landscape edging. For example, using a miter saw or a saw blade not designed for metal can result in poor quality cuts, damage to the tool, and is a potential safety hazard. Always make sure you use the right cutting tools and accessories for the type and thickness of the garden metal border.
Rushing the Cutting Process
Cutting a metal landscape border requires patience. Rushing the process can lead to uneven cuts, overheating of cutting tools and even injury. Whether using an angle grinder, plasma cutter or metal saw, take the time to make accurate cuts. Follow the recommended cutting speed and technique for the tool being used.
Neglecting Safety Measures
Safety should always be the primary consideration when working with METAL GARDEN BORDER. Neglecting to wear proper safety equipment such as gloves, goggles and dust masks can result in serious injury. Failure to properly secure steel before cutting or follow safety instructions for cutting tools can also pose a significant risk. Always take the time to set up your work area safely and follow all safety guidelines.
VIII. What Precautions Should Be Taken When Cutting Metal Edging Of Different Thicknesses?
Thinner metal edge banding (usually less than 5 mm): In terms of tool selection, angle grinders should use thinner cutting blades. For example, when cutting 2-3 mm thick metal, 1-2 mm thick cutting blades are more suitable because they are more flexible and can reduce damage to thin materials; metal saws require saw blades with fine teeth and high TPI values, such as saw blades with 18-24 teeth per inch, which can make the cutting surface smoother. During operation, the angle grinder can be pushed at a slightly faster but uniform speed to prevent edge deformation caused by high temperature, and the cutting blade must be kept vertical; the pressure should not be too high when cutting with a metal saw to prevent thin metal from bending.
Thicker metal edge banding (usually greater than 5 mm): Angle grinders should be equipped with thicker and stronger cutting blades. For cutting 8-10 mm thick metal, 3-4 mm thick cutting blades are more suitable, and the material needs to be more wear-resistant; plasma cutters have obvious advantages in cutting thick metals, but the power must be adjusted accurately according to the thickness. For materials thicker than 10 mm, the power must often be adjusted to more than 100 amps; metal saws should use saw blades with fewer teeth but thicker teeth and a sturdy structure. Saw blades with 6-10 teeth per inch are more suitable. During operation, the angle grinder should slow down the cutting speed, apply force evenly and not too much force to prevent the cutting blade from breaking, and pause to cool down when overheating; plasma cutters should reasonably adjust the cutting speed according to the thickness, and slow down for thicker materials; metal saws should cut smoothly to avoid saw blade jamming.
Corten steel edging has a long service life, up to 20-50 years in general outdoor environments. Its unique alloy composition forms a protective oxide film that resists corrosion. However, the service life is affected by many factors. In harsh environments, such as high-salinity areas near the sea or areas with severe industrial pollution, the life span may be shortened to 15-30 years due to accelerated corrosion caused by salt and pollutants. Daily maintenance is also critical. Regular cleaning, removing accumulated dirt, leaves and other debris, and preventing moisture retention and rust can extend the service life; if early signs of rust are found, timely treatment will also help maintain its durability.
How Much Will 100 Feet of Edging Cost?
The cost of 100 feet of weathering steel edging fluctuates greatly. The price of weathering steel is affected by the thickness of the steel and market supply and demand. Generally speaking, the cost of 3-5 mm thick weathering steel is about $10-20 per foot, so the cost of 100 feet is about $1000-2000. If the thickness increases to 8-10 mm, the cost per foot may rise to $15-30, and the cost for 100 feet is $1500-3000. In addition, the cost also includes processing fees, such as cutting and bending, which will increase the cost. Transportation costs must also be considered. The farther away from the supplier, the higher the cost. Some suppliers may give discounts when purchasing in large quantities.
How Deep Should Steel Edging Be?
The depth of the steel edging depends on the actual use and soil conditions. For garden borders to prevent soil and lawn from mixing, the edging depth of 10-15 cm is more appropriate, which can stabilize the edging and resist daily trampling and rain erosion. If it is used to prevent the spread of plant roots, the depth should be increased to 15-20 cm, which can effectively block root growth. In soft soil, the edging depth should be appropriately deepened to ensure stability; in compact soil, it can be slightly shallower, but not less than 10 cm.
