Match the fence attachment first
Identify the actual wire or mesh attachment and the post geometry it must fit. Record stud or hole positions where they govern the connection, including top and bottom locations. Ask a proposed alternative to demonstrate fit against that assembly detail; a general claim that a clip suits Y-posts or T-posts leaves the relevant profile range unresolved.
Support any claim that a fitting suits Y-posts with a defined profile range. Check the actual post section and attachment dimensions; a similar overall shape does not establish compatibility.
| Drawing field | Purchasing purpose |
|---|---|
| Cross-section dimensions | Identify the profile and accessory fit |
| Total length | Distinguish supplied length from installed height |
| Hole or stud pattern | Match the intended attachment positions |
| End and top detail | Check installation and approved protective accessories |
| Coating | Confirm the ordered finish and relevant evidence |
| Mass basis | Compare like-for-like transport and material quantities |
Read kilograms per metre correctly
Suppose an illustrative post is 1.8 m long and has a stated mass of 2.0 kg/m on the supplier’s defined basis. Its calculated mass is 1.8 × 2.0 = 3.6 kg. For 250 posts, the calculated post mass is 900 kg before separately supplied accessories and packaging.
Confirm whether the supplier’s quoted mass includes coating, attached plates or other features. A figure of 2.0 kg per post is not equivalent to 2.0 kg/m. Record tolerances where the mass forms part of the agreed acceptance requirements.
Do not use mass as a capacity certificate
Post behaviour depends on section geometry, material, support conditions and loading direction. A heavier post may differ in useful ways, but weight alone does not establish allowable spacing or resistance in the installed fence.
Use the selected system’s design for line posts and the separate arrangements required at ends, corners and gates. A line post should not be substituted for a straining or gate support merely because its length is similar.
Trial the actual combination
Before committing a bulk order, compare an identified post, fitting and mesh sample with the approved drawing. Retain section, hole-pattern and finish references for delivery inspection and repeat supply. If an alternative profile is accepted, give it a distinct code so mixed bundles cannot create installation rework despite matching nominal length and colour.
Check delivery labels and separate any unapproved variant. A changed hole pattern can create site rework even if total length and colour still match the quotation.
For quantities along a route, use the post spacing and bracing guide. It distinguishes a count based on an already approved layout from designing the support system itself.
