Crossarm: Frequently Asked Questions

Short, direct answers to the questions buyers actually ask before ordering crossarms — collected from the specification, pricing and inspection questions that come up in real enquiries. Where an answer depends on your site conditions, the condition is stated rather than hidden.

Product questions

What is the usual galvanising specification for a crossarm?

Around 70–85 µm, tested by coating mass rather than by a thickness gauge alone, and with drain paths designed into the angle so the inside face actually gets coated. Arms with no drain path fail within five years inland.

Ordering questions

What is the typical minimum order and lead time for crossarm?

The usual minimum is 200 pcs, and repeat specifications run 25–40 days. First orders with new tooling or custom colours sit at the long end of that range; stock configurations sit at the short end.

How should crossarm be packed for export?

20 pcs per bundle, steel-strapped; holes must not be blocked by strapping. If your shipment routes through humid climates or long storage, say so in the RFQ — packing upgrades are cheap at the factory and expensive as a claim.

Which quality tests should accompany a crossarm shipment?

At minimum: coating thickness at three points per arm; dimensional check of the hole pattern; load test of the centre mounting; visual inspection for bare edges. Type-test certificates qualify the design; ask additionally for per-batch routine records, which are what tell you what actually shipped.

What goes wrong in the field with cheap crossarm?

The recurring failure modes are: zinc starved inside the angle; hole pattern drifting between batches. None of them are visible at goods-in, which is why the specification and the batch records matter more than the sample.

A note on honest specifications

Every answer above comes from the same product data behind the specification guide and the inspection checklist for this product. If your question is not answered here, put it in the quotation request — a supplier who answers an awkward question narrowly and honestly is worth more than one who answers everything with “yes, no problem”.

When this is the wrong product

Crossarms are the right tool when three-phase distribution lines; bracket arms for transformer mounting. If your situation is closer to “line conversions and upgrades” — or you are not sure — read the category guide first and check whether a sibling product fits better before you price the wrong one.
