Square, Round, Rectangular or Peach Posts for Welded Mesh Fence Panels?

A compatibility guide for 3D, 656 and 868 panels, clips, centre spacing, foundations and replacement batches

Article copy

A welded-mesh fence post cannot be selected from shape alone. Square, round, rectangular and peach profiles create different faces, bending directions, cap arrangements and fixing interfaces. The panel width and wire build-up determine the required clearance and post centre spacing, while fence height, site exposure, gates and ground conditions influence section, wall and foundation design.

MaiFa publishes square, round, rectangular and peach-post directions for 3D fence panels and also lists these directions in current double-wire product content. This confirms available product families, not universal interchangeability. A buyer should approve one panel-post-fixing assembly and retain its drawings for installation and future replacement.

Compatibility rule: freeze the panel first, then choose a post profile and matching clip, bracket or cover system. Confirm post centres, wire clearance, foundation interface and trial assembly. Do not assume that 3D, 656 and 868 panels, or different production batches, can share the same posts.

1. Quick comparison

The table is a procurement map, not a substitute for project design. Every final selection should be repeated in the quotation and approved drawing, with unresolved decisions and excluded evidence clearly marked.

2. Freeze panel geometry and centres first

State the product family, finished panel width and height, wire arrangement, mesh, V-bend profile where applicable and finished tolerance. The post-centre dimension must account for panel width, connector thickness, installation gap and any overlap. A nominal 2500 mm panel should not automatically be installed at 2500 mm centres unless the approved connection drawing says so.

For 3D panels, bends and wire intersections can affect clip positions. For 656 and 868, twin horizontal wires create different clearances at fixing rows. If the same post is proposed for both, require drawings and trial assemblies for each panel rather than approving the post in isolation.

• Mark finished panel width and post centres as separate dimensions.
• Show wire location at every clip, bracket or cover bar.
• State the permitted installation adjustment.
• Control panel, post and fixing drawings under one system revision.

3. Compare the fixing concepts, not only post profiles

Square and rectangular tubes may use discrete clips, brackets or continuous cover bars. Round posts need a connection formed for the stated outside diameter. Peach posts may use profile-specific grooves or hooks. Each concept should state component material, thickness, hole or slot locations, bolt diameter and grade where required, finish, fixing count and installation method.

A secure-looking fastener photograph is not enough. If tamper resistance matters, name the head, mating part, tool and access condition. Check whether the fixing can be installed and replaced without damaging panel coating or requiring an unapproved site modification.

• Request an enlarged fixing section and elevation.
• List clips, bars, bolts, washers, nuts, caps and tools as separate parts.
• Check coating contact and repair rules at metal-to-metal interfaces.
• Include buyer-defined spare packs under stable part numbers.

4. Select wall, length and foundation from project inputs

Post profile does not determine structural adequacy by itself. Section size, wall, steel requirement, fence height, bay width, wind, terrain, attached screening, gate loads, corner geometry and foundation all matter. A rectangular post also has a strong and weak orientation that must be shown. The supplier can quote selected post options, while the responsible project team confirms the structural and foundation design.

Base-plated and embedded posts require different lengths and interfaces. For base plates, provide substrate, anchor requirements, edge distances and level tolerance. For embedded posts, provide ground, foundation concept and required post length. Do not copy one foundation detail across all sites.

• Separate line, end, corner and gate-post schedules.
• Show post orientation at every direction change.
• Disclose screens, signs and mounted equipment.
• Record whether anchors or civil works are included or by others.

5. Control slopes, corners and replacement compatibility

Slopes may be stepped, raked or resolved with special panels; each approach changes fixing positions and post length. Corners can require different post faces, double fixing rows or two posts. End posts and wall returns need termination details. These conditions should appear in the quantity take-off so installers do not improvise by drilling or welding finished posts.

For repeat orders, preserve approved profiles, wall, hole and clip dimensions, color, coating route and system revision. If tooling or profile changes, require written compatibility review and a trial bay with old and new components. The statement same size is insufficient when internal radii, groove depth or hole position have changed.

• Issue location-specific drawings for slopes and corners.
• Label special posts by fence-zone ID.
• Retain reference samples or full dimensional records.
• Confirm backward compatibility before ordering replacement batches.

7. A defensible selection workflow

• Select the exact 3D, 656 or 868 panel configuration.
• Define line, end, corner, slope, base and gate conditions on the layout.
• Choose post profile, section, wall, length and connection concept.
• Complete project review of wind, ground, foundation and gate inputs.
• Trial-assemble production panel, post, clips and bolts.
• Approve labels, spares and revision records for future compatibility.

8. What the quotation should include

9. Copy-ready inquiry template

Please quote a compatible post and fixing system for [3D/656/868] panels at [finished H x W, wire and mesh]. Proposed post direction: [square/round/rectangular/peach]. State exact section or OD, wall, length, orientation, post centres, cap, base or embedment, clips/brackets/cover bars, bolt set, fixing positions, finish and tolerances. Include line, end, corner, slope and gate posts; foundation and anchor scope; spare fixing packs; production trial bay; packing; and [Incoterm] to [named place]. Confirm replacement compatibility only against the attached revision or sample.

Frequently asked questions

Which post is best for 3D fence panels?

There is no universal best profile. Select the post and connection that fit the exact panel, project and installation method.

Can 656 and 868 panels use the same posts?

Possibly in a designed product family, but do not assume it. Check wire clearance, posts, fixings, loads and trial assembly.

Is a peach post stronger than a square post?

Shape alone does not establish adequacy; section, wall, orientation, spacing, foundation and loads all matter.

Is panel width the same as post centres?

Not automatically. The connection detail and installation gap determine centres.

Can line posts be used at corners or gates?

Do not assume so. These conditions need separate connection and load details.

What should be kept for replacement orders?

Drawings, profile dimensions, wall, hole positions, clips, bolts, finish, sample and revision record.
