Corten steel lawn edging is typically supplied in modular standard sections, though custom lengths are also available for complex or large-scale landscaping projects.
The length of the edging directly affects the number of seams, transportation challenges, installation efficiency, and material waste. For simple, straight lawn borders, standard sections are the preferred choice, offering the best value for money.
For curved flower beds, extra-long commercial borders, or situations where you wish to minimize visible seams, you can consult with the supplier to arrange custom cutting or pre-bending solutions.
Of course, length is just one parameter. Before placing an order, you’ll need to confirm the height, sheet thickness, profile style, fastening method, and corner treatment solutions.

Garden lawn edging available on the market is generally produced in modular sections; it is rarely manufactured as a single, infinitely long steel strip.
Common standard section lengths include 1,000 mm, 1,075 mm, and 2,000 mm, though specifications may vary by manufacturer.
The benefits of a modular design are clear: it makes handling, packing, and on-site installation much easier. However, segmented sections inevitably result in seams, so the connection structure must also be confirmed in advance during the procurement process—it cannot be left until the construction phase.
AHL’s standard segment length is 1,075 mm, available in two thicknesses and two heights:
These dimensions can serve as the basis for calculating project quantities. However, before placing a large-volume order, be sure to verify the latest product specifications. Manufacturing tolerances, overlap allowances, and cutting allowances will all affect the effective length after installation.
Longer sections reduce the number of seams along straight sections. Fewer seams simplify alignment and adjustment, and fewer connectors are required for on-site installation.
However, longer panels also have their drawbacks. The longer the panels, the more difficult they are to transport and handle, and they can be challenging to maneuver through narrow garden paths.
The ideal length essentially involves striking a balance between the number of seams, ease of handling, and site layout.

Standard specifications are ideal for frequent restocking and inventory management, making it easier to plan construction schedules. They are well-suited for conventional designs such as straight lawn borders, garden paths, and rectangular flower beds.
For dealers, standard specifications simplify quoting and make it convenient to restock or replace parts later. Contractors can begin work immediately upon receiving the materials, without having to wait for custom production lead times.
Custom lengths are better suited for large-scale commercial landscapes, irregular planting areas, unique boundary designs, or projects where on-site cutting needs to be minimized. Custom cutting also allows the seams of flexible metal garden edging to align with paving joints, steps, and other landscape features, resulting in a neater overall appearance.
Customization does not necessarily mean cost savings. While it can reduce on-site cutting waste and shorten construction time, it increases processing and packaging costs, and the delivery lead time will be longer.
AHL can negotiate custom lengths, heights, thicknesses, and cutting plans based on project requirements, provided they are technically feasible.
You will need to provide layout drawings with dimensions, total linear meters, corner details, and radius requirements for curves. Additionally, please confirm: whether custom lengths can be produced, the packaging and shipping plan, and whether cutting will be completed prior to shipment.

For straight edges, simply lay standard sections continuously. Plan the joint locations in advance to minimize the amount of very short scrap pieces left over at the end.
We recommend using a string line for layout. Check alignment frequently during installation to ensure the line remains straight.
For curved areas, use corten flexible edging or factory-pre-bent products. Do not force straight sections to form tight curves, as this can cause deformation and compromise the final appearance.
You can first use a hose to outline the curve and confirm the radius. Before placing an order, clarify with the supplier whether pre-bent sections are available or if the installation team will need to bend them on-site.
For large projects, divide the total perimeter into multiple construction zones, positioning seams along pathways, paving joints, and areas with elevation changes. This facilitates batch delivery, phased construction, and simplifies future maintenance.
Calculate material quantities based on drawings whenever possible; do not rely solely on total length estimates. Ask suppliers to provide cutting lists to verify material usage.
For small gardens with simple designs, standard edging is sufficient. When planning the cutting layout, try to ensure that leftover sections are long enough to facilitate reuse and guarantee secure fastening.
Do not base your purchase quantity on the theoretical minimum. Corners, minor adjustments, and cutting waste will all result in additional material consumption.

Measure the edges of the lawn, the sides of walkways, and the borders of flower beds. Record straight sections and curved areas separately. For curved areas, measure along the centerline of the edging; do not simply measure the straight-line distance between the two ends of the flower bed.
Using the AHL 1075mm standard section as an example: Number of sections required = Total length (mm) ÷ 1075
Round the result up, then account for joints, corners, and cutting waste based on your layout.
The installation method affects the effective installation length of each section. Overlapping joints and connecting plates will occupy a portion of the length, so the actual usable length will be less than the nominal length.
At corners, a bevel cut or specialized corner pieces are required. For exposed landscape edging, the corner solution must be confirmed in advance to avoid unsightly seams after completion.
A 20-meter-long straight boundary: Total length: 20,000 mm; Single-section specification: 1,075 mm; Theoretical number of sections: 18.6; Actual purchase: 19 sections
This calculation assumes that each section can be laid in its entirety. Be sure to reconfirm the final effective coverage length with the supplier, taking the connection method into account.

AHL offers two thicknesses: 1.6 mm and 2.0 mm. Thickness should be selected based on the application, soil pressure, and on-site handling conditions—do not base the decision solely on appearance.
For commercial projects, confirm whether the thickness listed in the quote refers to the base material thickness or the finished product thickness, and request a material certification.
Available heights are 100 mm and 150 mm. Part of the edge will be buried underground, so the height exposed above ground will be less than the total height.
Confirm the desired finished height, burial depth, and soil conditions in advance. For applications requiring earth retention or where distinct vertical lines are desired, choose a taller profile.
Select straight profiles for linear designs to achieve clean, crisp lines; choose flexible or pre-curved profiles for curved designs.
Before selecting a model, confirm the minimum bending radius, as not all edging profiles support on-site bending. This directly affects the installation method, joint spacing, and final appearance.
Confirm the required accessories—such as ground anchors, connecting plates, and screws—and verify whether the quote includes these components. For exposed edging, pay close attention to joint alignment solutions; a high-quality connection structure ensures stability while minimizing the visibility of seams.

There is no uniform industry standard. AHL’s standard single section is 1075 mm; specifications vary among other manufacturers.
Yes, subject to manufacturing constraints. AHL supports customization of length, thickness, height, and pre-cutting.
Divide the total perimeter length by the effective coverage length of a single section, round up to the nearest whole number, and allow extra for corners and cutting waste.
This depends on the profile, thickness, and target radius. For curved sections, prioritize flexible profiles or factory-pre-bent components.
Yes. Longer sections have fewer seams but are more difficult to transport and install on-site. We recommend comparing the total project cost rather than focusing solely on the unit price per section.
There is no universal optimal length. Prioritize flexible or pre-bent profiles, and confirm the bending radius, seam locations, and installation method with your supplier.
Yes. Provide the total length in meters, profile type, height, thickness, and drawings to obtain a detailed quote that breaks down costs into main materials, fabrication, accessories, and shipping.
For straight edges, prioritize the standard 1075mm sections; For butt joints, curved sections, or special shapes, choose custom cutting. Before placing an order, clearly confirm the height, thickness, profile style, and mounting solution.
