Y Post vs Star Picket: Choosing the Right Fence Post
Y post vs star picket is the question that decides the cost and holding power of every steel-post fence, and the two names are often used for the same product by different suppliers. Both are driven steel posts with a pointed foot and holes for wire, but the cross section, weight and length options differ, and those differences decide how the post behaves in soft ground, in wind and under a strained netting panel. This comparison sets out the profile, typical weights, lengths, coating and holding power, so you can specify one post type and stop mixing them on the same run.
What the Two Names Actually Mean
A star picket is a steel post with a Y-shaped section that tapers to a sharp point, driven with a driver and held by friction and the disturbed soil around it. A Y post is the same family of product, usually the heavier end of the range with a more pronounced Y web and a longer taper. In practice the names overlap: a supplier may list one catalogue line as both. What matters is not the label but the section thickness, the weight per metre and the length fabricated to the tolerance you need.
Profile and Weight
Section and Web
The Y section gives the post stiffness in two directions without the mass a round tube would need. A deeper web and thicker section raise the drive resistance and the pull-out force, which is why heavier posts are specified for netting, for wind-exposed sites and for corners where tension collects.
Weight Per Metre
Light pickets run around 1.58 kg/m and heavier Y posts around 2.04 kg/m. On a 1,000 post order that difference changes the container payload and the price per post more than the headline rate suggests, so quote against kg/m rather than against a photo of the section.
Length Options
Common lengths are 1.8 m, 2.1 m and 2.4 m. A 1.8 m post driven 400 to 500 mm leaves a little over 1.3 m above ground, which suits stock fencing; 2.1 m gives more margin in loose or sandy soil; 2.4 m is used where the fence must stand above a bank or where a higher wire line is required. Decide the driven depth first, then choose the length that leaves the exposed height you need.
Coating and Life
Hot dip galvanized coating is the working default: it survives soil moisture, fertilizer runoff and the abrasion of a driver better than a thin electro coating. Ask for the coating mass per square metre, not just the word galvanized, and match the coating class to the site - coastal and high-rainfall ground needs more zinc than dry inland pasture.
Holding Power in Real Ground
Pull-out resistance comes from soil compaction around the post and from the depth driven, not from the paint colour. In firm loam a light picket holds a stock fence well; in sand, peat or recently cultivated ground the same post leans under tension within a season, and the fix is a heavier section, a deeper drive or a stay, not more posts at the same spacing.
Which Post for Which Animal
Sheep and Lambs
Sheep push low and rub, so the fence needs posts that stay vertical under a tight mesh panel. Heavy Y posts at 3 m centres with strainers at corners are the usual choice, and the bottom wire sits close to the ground.
Cattle
Cattle lean and rub hard against a fence. A heavier post section and shorter post spacing near gateways and crush areas reduce the leaning that starts every repair cycle.
Netting and Wind-Exposed Sites
A netting panel catches wind like a sail. On exposed boundaries, use the heavier section, add stays at intervals and set posts deeper than the stock-fence standard.
Mixing Post Types on One Run
Samples from two mills rarely share dimensions, and a driver set for one section damages the other. If both types must be used, keep them on separate runs, order clips that fit each section and record which post went where. On a contract with staged deliveries, that record is the difference between a clean handover and a fence that will not tension.
What to Specify in the Enquiry
Send the post type, section weight in kg/m, length, coating class, quantity, clip type and destination port. With those six points a supplier can quote a matched set of posts, clips and caps rather than three items that arrive incompatible.

FAQ About Y Posts and Star Pickets
Q: Is a star picket the same as a Y post?
Largely the same product family. The useful difference is section weight and length, so specify kg/m and metres rather than relying on the name.
Q: What length post do I need for a stock fence?
1.8 m with 400 to 500 mm driven is typical for stock fencing; 2.1 m suits loose ground or a higher exposed line.
Q: How much does post weight matter?
A light picket is about 1.58 kg/m and a heavy Y post about 2.04 kg/m. The heavier section resists leaning and pull-out far better under netting.
Q: Can light and heavy posts be mixed on one fence?
They can, but keep types on separate runs, use clips that match each section and record the placement.
Q: Do you supply posts, clips and caps together?
Yes. Send type, kg/m, length, coating class, quantity and destination port to Dutai. WhatsApp / Mobile: +86 158 0311 4155 | Email: sales@cndutai.com or info@studdedtpost.com. Address: Anping City, Hengshui City, Hebei Province, China.
