How to choose a highway fence for roads and railways

Start with the opening size

The opening controls how much of the barrier remains open while setting the size of objects that can pass through it. Our rectangular mesh sizes include 50 × 150 mm, 60 × 120 mm, 75 × 150 mm, 80 × 160 mm, 90 × 170 mm, and 50 × 200 mm. The product range also includes a 9 × 17 mm galvanized mesh option.

For road and rail applications, we recommend a mesh size no larger than 80 × 160 mm. This gives you a defined upper limit for the opening while leaving several choices below it. A smaller opening can suit a project that requires tighter separation. Measure the required clear opening on the project drawing, then compare it with the mesh size before fixing the panel order.

Match wire diameter to exposure

Wire diameter ranges from 3.5 mm to 6.0 mm. The road and rail recommendation is at least 5.0 mm. This is a suitable starting point for fencing along transport corridors, where the barrier may face contact from pedestrians, animals, maintenance activity, or small vehicles. The fence can withstand general external impact, including collisions with pedestrians and small vehicles. The specific load-bearing capacity depends on the wire diameter and column configuration.

A 5.0 mm or larger wire suits a corridor protection project that needs a stronger panel than a basic isolation fence. Consider the wire together with the post diameter, wall thickness, and spacing. Wire diameter alone does not define the whole fence capacity.

Select the panel and post dimensions together

Standard fence heights are 1.2 m, 1.5 m, 1.8 m, and 2.0 m. A 2.4 m height is also available as a customizable option. Standard lengths are 2 m and 3 m, with lengths up to 6 m available for customization.

The columns can be round steel tubes with 48 mm or 60 mm diameters, or 50 × 50 mm square tubes. Wall thickness ranges from 1.0 mm to 2.5 mm, and column heights range from 1.5 m to 3.0 m to match the mesh. For the road and rail configuration, we recommend a 60 mm column with a 2.5 mm wall. Standard column spacing is 2.5 m to 3 m, adjusted according to mesh length.

Picture the installation beside a long rail boundary: panel length affects the number of joints, while column spacing affects how the fence follows the alignment. For bridge decks and cement floors, specify the flange option. The flange is installed at the bottom of the fixed column and has a thickness of at least 4 mm. A rain hat can be added to the column to prevent water accumulation inside it.

Choose the finish for the site environment

The fence is available in low carbon steel and stainless steel. Low carbon steel wire options include Q195/Q235 wire, cold drawn wire, and galvanized steel wire. Surface treatments include plastic dipping, plastic spraying, hot-dip galvanizing, and cold-dip galvanizing.

For road and rail use, we recommend hot-dip galvanizing plus plastic dipping. Plastic dipping is specified at 0.8 to 1.2 mm, and hot-dip galvanizing has a zinc layer of at least 60 μm. With this hot-dip galvanizing and plastic dipping combination, the listed service-life range is 8 to 15 years. Plastic-coated colors include grass green, dark green, white, yellow, black, and blue.

This combination suits an outdoor transport corridor where corrosion protection and a visible finish both matter. Send the site environment and color requirement with the inquiry so we can match the finish to the project.

Choose the connection for the installation method

Two connection methods are available: snap-on connection for quick installation and anti-theft bolt fixing. Select the connection method according to the installation arrangement and the fixing detail shown on the project drawing.

The fence has a modular structure with reinforcing wire on both sides of the mesh. That double-sided wire forms the frame and improves fence stability. Posts, spacing, connection method, rain hats, and flanges should be treated as one installation package. This is especially important on bridge or cement-floor sections, where a flange-mounted column may be required instead of a buried post.

Questions to settle before ordering

Send the corridor details with the inquiry

Choose our Highway and Railway Fence for road and rail boundaries that call for at least 5.0 mm wire, mesh no larger than 80 × 160 mm, 60 mm columns with 2.5 mm walls, and hot-dip galvanizing plus plastic dipping. Send the route type, total length, height, mesh opening, surface condition, column spacing, connection method, finish color, and quantity for a project quotation.
