Panel geometry and available sizes

The 358 system uses a fixed mesh opening of 76.2 × 12.7 mm. Panel lengths are 2 m, 2.5 m, and 3 m, and panel heights are 1.8 m, 2 m, and 2.4 m. Wire diameter is 4 mm or 5 mm. The continuous welded-wire layout suits a buyer who needs the same narrow opening across every bay of a perimeter.

The picket system uses separate vertical pickets and horizontal rails. Panel sizes include 1.8 × 2.4 m, 2.1 × 2.4 m, and 2.4 × 2.4 m. Rail sections are 30 × 30 mm, 40 × 40 mm, or 50 × 50 mm, with rail thicknesses of 1.0 mm, 1.2 mm, and 1.5 mm. Pickets are 19 × 19 mm, 20 × 20 mm, or 25 × 25 mm, with thicknesses of 0.8 mm, 1.0 mm, and 1.2 mm.

Picture the two fence lines at the site. A 358 bay presents a fine mesh from post to post. A picket bay leaves the gap between vertical members visible, so the spacing and top profile become part of the elevation. Picket spacing is 90 mm, 100 mm, 120 mm, or 150 mm. Top choices include flat top, spearhead top, and bent top.

Posts and installation layout

The 358 system uses post sizes of 60 × 60 mm, 60 × 80 mm, 60 × 120 mm, and 80 × 80 mm. Post thicknesses are 1.5 mm, 1.8 mm, 2.0 mm, 2.5 mm, and 3.0 mm. Post height is usually 500 mm longer than the fence height. For a 2.4 m visible fence, your order drawing should show the panel height and the corresponding post length together.

The picket system uses 50 × 50 mm, 60 × 60 mm, and 80 × 80 mm posts, with post thicknesses of 1.5 mm, 1.8 mm, and 2.0 mm. Its panel width is 2.4 m in the 1.8 m, 2.1 m, and 2.4 m high configurations. Measure the fence run, corners, gates, and end conditions before choosing the panel combination. A bay-by-bay drawing lets us match the panel, rails, pickets, and posts.

The installation decision follows the layout. Select the 358 arrangement when the enclosure needs a consistent 76.2 × 12.7 mm mesh and a specified wire diameter. Select the picket arrangement when the order depends on panel height, picket gap, rail section, and top treatment. In either case, measure gate openings and corner returns before finalizing the number of bays.

Material and surface treatment

The 358 system uses high-tensile steel wire with a hot-dipped galvanized surface. The picket system uses galvanized steel and combines hot-dip galvanizing with powder coating. These are both steel fence systems, so an aluminum specification should not replace the actual material selection in your purchase drawing.

The picket finish gives the design brief more choices for visible boundary fencing. Color options include RAL 9005 black, dark green, blue, and white. The 358 configuration centers on mesh opening, wire diameter, panel dimensions, post dimensions, and post thickness, with hot-dip galvanizing as the surface treatment.

For a garden boundary, send the desired height, 2.4 m panel width, picket spacing, rail section, picket section, top design, and color. For a security enclosure, send the required height, panel length, 4 mm or 5 mm wire diameter, post size, and post thickness. We can then prepare a coherent layout instead of treating a search phrase as a specification.

Questions to settle before ordering

Match the fence to the project brief

The 358 system suits a buyer specifying fine welded-wire geometry, 4 mm or 5 mm wire, and square posts for a security perimeter. The galvanized steel picket system suits a buyer choosing panel proportions, picket spacing, rail and picket sizes, top design, and powder-coated color. See our high-security 358 anti-climb fence for the mesh option, then send the fence run, heights, corners, gates, panel lengths, post sizes, finish, and quantity for a quote.
